Hydrostatic Level Measurement Settings for SITRANS P320/420


SIEMENS SITRANS P320/P420 pressure transmitters are digital pressure transmitters featuring extensive user-friendliness and high accuracy. SITRANS P hydrostatic level technology can handle extreme conditions and is widely used in the environmental, chemical and petrochemical industries.  SITRANS P pressure/differential pressure transmitters are extremely resistant to chemical and mechanical loads as well as commonly occurring electromagnetic interference.

SITRANS P320/420 is the first pressure transmitter on the market to feature remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually programming each individual device across a facility, operators can access transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. Both pressure transmitters have an increased proof test interval over other devices on the market with testing periods of up to fifteen years rather than every two. This lowers maintenance costs significantly.

Lead-Free Valves from ASCO and Ives Equipment



Lead is extremely toxic. Tight US safety regulations affect manufacturers of products such as drinking water fountains, reverse osmosis systems, coffee machines. and commercial kitchen equipment. A lead-free system cannot contain soldering flux with greater than 0.2% lead content, or more than a weighted average of 0.25% lead in the wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures. Under the law, lead free is a cumulative concept.  In response, Ives Equipment and ASCO have coordinated to provide a range of valve choices that meet the new regulations, are NSF certified, and come in the industry’s broadest range of characteristics in terms of pipe size, pressure or temperature ratings, and flow coefficients.

Industrial Control Systems (ICS) Face New Ransomware Concern

Industrial Control System Ransomware

Dragos is a company that provides industrial asset identification, threat detection, and response to help organizations stay ahead of adversaries. According to Dragos intelligence and threat reports, it appears that a segment of code called Snake or EKANS, first recognized in December, 2019, has been designed as ransomware to target Windows systems used in industrial control systems (ICS). 

Ransomware is malicious software that will lock up data on a computer’s drive, then travel across the network and encrypt other data. The saboteurs will then demand payment in exchange for releasing the data. Whereas industrial control system machines are high-value targets (healthcare is the other high-value target) EKANS is unusual in that the malicious code uses targeted intelligence for control systems to first encrypt the root data (files are encrypted and renamed with random 5-character extension) and then ruin the software processes and hold the data hostage.

EKANS targeted companies and are sent a ransom note with the instruction to pay the ransom in cryptocurrency. There is an email address provided for contact/replies.

Manufacturing plants, power grids, and industrial concerns (such as oil refineries) are all targets of this malicious malware.

Another feature of the EKANS ransomware is it is programed to terminate sixty-four (64) various processes on computers – most of which are ICS specific.  This suggests the possibility that the EKANS may also share features similar to the Megacortex ransomware, which first appeared in early 2019.  Megacortex relies on a manual method of deployment rather than self propagation ransomware deployment.

It is still unknown whether the EKANS ransomware originated from state-sponsored hackers or via real cybercriminals trying to profit from industrial control system owners. It appears that it may be the latter, based on the most recent analysis of the nature of the ransomware – analysis by Dragos researchers.

It is wise to raise awareness with among everyone who touches your systems and it would be prudent to have someone within your organization (or a consultant) tasked with keeping data security protections current.  In addition, it is crucial to have ICS organizations rethink their cybersecurity leadership philosophy. In many organizations, the evangelists for cybersecurity are not equipped to exert influence in the company.  Cybersecurity is still treated as a back-office job, but it needs to be treated as priority by the organizational leaders.

Dragos adversary hunters recommend keeping ICS systems segmented from the rest of the network. In this way, if just one Window machine is infected, the virus can’t mobilize to the systems that control the infrastructure. In addition, standard practices such as backups, stored offline, and including the last known good configuration data will somewhat reduce the liability of slow recovery. Guardrails such as improved access and mechanisms for authentication will also help to reduce the risk of these increasingly troubling attacks on ICS systems.

Don't Risk Equipment or Safety: Freeze Protect Your Plant Now

industrial heat tracing and freeze protection
Don't let this happen at your plant.
Winter is here in its full glory. Plant engineers and plant maintenance have to pay special care in preventing freezing in pipelines, tanks, Vessels, conveyors, and impulse lines.  The cold temperatures in the Mid-Atlantic can often damage or destroy process equipment and it's valuable contents. Most commonly, pipes, instrumentation, and valves are the vulnerable items affected by the sudden drop in temperatures, causing devastating consequences, including costly downtime and unplanned outages. But there's also safety issues to be considered with snow and ice build up, so attention must be paid to snow and ice melting.

Main Categories for Industrial Heat Tracing


  • Industrial Pipe Tracing Cable
  • Industrial Tank and Vessel Heating
  • Industrial Snow Melting
  • Industrial Roof Gutter Deicing

Responsible facility management includes protecting buildings and equipment against freeze damage. There are many items in any given manufacturing plant to protect, including piping systems, process instrumentation, holding tanks, transfer vessels, and valves. For each of these items, there's a good freeze protection solution to be applied. Here are some of the more common heat tracing products used in these applications.
Self-regulating Heat Tracing Cable

White Paper: Predicting Cavitation Damage in Control Valves

Cavitation can occur in control valves handling fluids, causing loud noise as well as damaging valve components and ultimately leading to additional costs in process plants. A standardized procedure to evaluate the destructiveness of cavitation-induced still does not exist whereas noise emission can reliably be predicted with the international EN 60534-8-4 standard. This white paper, courtesy of Samson Controls, describes a method to solve this problem by evaluating structure-borne noise in the ultrasonic range.

Reducing Material Waste in Flexible Pet (Polyethylene Terephthalate) Production

Reducing Material Waste in Flexible Pet

Polyester is very popular because it is a light, soft, flexible, low-maintenance material that keeps you warm. Making it this way poses diverse challenges to PET producers.


A chemical plant specializing in producing PET was looking for a solution to reduce the waste resulting from product variance. The factory produces 25,000 tons of polyester annually, which is then provided to other manufacturers to produce a vast range of end products.

SITRANS FC430
The SITRANS FC430
monitors the glycol flow.
This vast range requires different PET grades, which are achieved by slight variations in the synthesis procedures. In order to investigate possible options to upgrade their primary processing, understanding the complete process is vital. In the case of PET production, this process starts with mixing three key ingredients – PTA and IPA powder along with glycol liquid – in specific ratios to make a paste.

These source materials are stored in stainless steel bins with a volume of 2649 ft3. Rotary feeders move the mate- rial from these bins to a batching vessel along with glycol to make the polyester paste. The batching vessel is agitated to ensure that the mixture is always consistent. Monitoring tank levels, precisely controlling the dosing, the efficient use of raw materials and ensuring a consistent mix are the key parameters
SIWAREX WP251
SIWAREX WP251
when it comes to improving the primary processing. When Siemens designed a new system for the chemical plant from the bottom up, the Siemens S7-1200 PLC controller was the first product that was installed to set up a compact and flexible automation solution, which keeps track of the key parameters and the process efficiency.

Don’t get mixed up during mixing

Each raw material bin is mounted on Siwarex WL280 ring torsion load cells to achieve optimum weighing accuracy. These load cells are connected to two Siwarex WP251 weighing modules, which are specifically designed for batching applications. The advantages of this solution are that the WL280 load cells feature a C3 class rating for accuracy as well as an IP68 rating for protection against dust and direct high-pressure cleaning – ideal for handling powder materials such as PTA. In connection with the Siwarex WP251, a customer-specific application was engineered with a resolution of up to +/- 4 million parts.

SITRANS TS500
SITRANS TS500
The glycol as the liquid component in this process is monitored by a Sitrans FC430 coriolis mass flowmeter providing a 4-20 mA output, which varies based on the flow rate of the material. This signal is fed into an analog S7-1200 input module. A Sipart PS2 positioner controls the valves to regulate the flow rate. In such flexible processes as this one, the operator individually sets the setpoint for total production. At the field level, this flexibility is achieved using Sinamics variable frequency drives, which independently adjust the flow rate of each material. To close the loop, the discharge rates from the raw material bins are monitored by the WP251. The output is then processed by the S7-1200 controller, sent through an analog module to control the Sipart PS2 positioner – which in turn allows more or less glycol to flow into the batching vessel. The downstream Sitrans FC430 flow meter additionally verifies the flow rate to ensure a high-quality mix.

How powder and liquid become PET

Pointek CLS200
Pointek CLS200
The temperature of the paste is another crucial factor when it comes to producing high-quality PET. If the agitation causes too much heat, the whole mixture could be lost, causing unwanted waste. In this configuration, a TS500 controls the temperature to the optimum level. To further cut down on product loss, a Pointek CLS200 capacitance- based switch acts as a backup device to ensure that the material discharges completely, and does not build up or overflow. Its high frequency oscillation makes it insensitive to product buildup, therefore guaranteeing reliable level monitoring in the PET paste vessel. For integrated control and alarm management, the level switch is connected to the S7-1200 controller. With 13 sensors, 2 VFDs, 3 geared motors, 4 modules and 1 HMI installed and connected to the control system, the plant managers reap the benefits of a comprehensive portfolio from one supplier. The new equipment is reliable and efficient and – together with the DCS solution – offers excellent process and data control.

Less material waste and reduced downtimes

SIPART PS2
SIPART PS2
Where did this leave the chemical company? After the equipment had been running for 3 months, the first estimates were made as to whether the initial goals of reduced waste and increased efficiency had been met. The result: plant efficiency had increased by 27 % due to the reduced material waste and product loss. Further, the more reliable process measurements and diagnostics help the company to service their equipment on a preventive basis instead of a reactive one, resulting in reduced downtimes and in- creased reliability.

Simplified diagram
Simplified diagram showing the customer’s process.
So the next time, you put on your running gear, take a sip out of a plastic bottle or attach your safety belt, maybe you will remember the effort that goes into producing the PET that is needed to manufacture these types of products. By the way – they have another important characteristic in common as they can be completely recycled.

NH3 Slip Measurement in the Fluidized-Bed Catalytic Cracking Process


AN APPLICATION NOTE FROM SIEMENS PROCESS ANALYTICS

Fluidized-Bed Catalytic Cracking (FCC) is the most important and widely used refinery process for converting low value heavy oils into more valuable gasoline and lighter products.

The typical FCC process will convert 75% or more of the heavy oils to gasoline and lighter products. Originally, chemical cracking was accomplished by heating the oil to super high temperatures but the catalytic process has almost completely replaced thermal cracking.

The cracking process produces carbon (coke) which remains on the catalyst particle and rapidly lowers its activity. To maintain the catalyst activity at a usable level, it is necessary to regenerate the catalyst by burning off the coke with air. As a result, the catalyst is continuously moved from reactor to regenerator and back to reactor.

What Are Pneumatic Actuators?

rack and pinion actuator
Internal view of rack and pinion actuator
(Flowserve Worcester)
Pneumatic valve actuators are used in extreme conditions in many industries such as oil and gas, chemical, water and wastewater, bulk storage, pulp & paper, and power generation. These devices are used in a multitude of valve control processes for regulation (or cessation) of flow, controlling pressure and adjusting level.  Due to their reliability and simplicity, pneumatic actuators are one of the most popular types of actuators used in industry today.

Pneumatic valve actuators work by conversion of air pressure into motion. The device applies a force of air to a diaphragm, rotary vane, or piston that is attached to the actuator shaft, which is then mechanically connected to the stem of the valve or damper. Depending on the type, pneumatic actuators produce either linear or rotary motion. 

ACTUATOR ACTION - SPRING RETURN OR DOUBLE ACTING

Spring Return — Pneumatic actuators with spring return design have air supplied from one side. The spring on the opposite side is responsible for the motion. With this design, air compression moves the opens or shuts the valves while the spring is responsible for the opposite motion. 

Double Acting  — Double acting actuators have air fed on both sides of a piston. The pressure on one side is higher as compared to the other that results in the required in movement. Air is used to open and close the valves.  

Diaphragm actuator
Diaphragm actuator
(Samson)
PNEUMATIC ACTUATOR DESIGNS

Diaphragm Actuators — Diaphragm actuators work by applying pressure to a thin membrane or diaphragm. 

Piston Actuators — Piston actuators apply compress air to a piston that is within a cylinder. Air is fed into a chamber that moves the piston in one direction. The piston moves in the opposite direction when air pressure is removed (spring assisted) or directed to the other side (double acting). 

Rack and Pinion — Rack and pinion actuators produce rotation by applying pressure to pistons with gears that turn a pinion gear. Rack and pinion actuators can be spring return or double acting. They are valued because of their compact size and versatility.

Scotch Yoke — A scotch-yoke actuator contains a piston, yoke, connecting shaft, and rotary pin.
Scotch yoke actuator

(Samson)
They can be direct acting or spring return. They are capable of providing very high torque outputs and are generally used on larger valves. Scotch yoke actuators can be powered by air or process gas.

Rotary Vane —Vane actuators use a mechanical vane, connected to a shaft, that separates a circular shaped body in two "clamshell" halves. The vane moves in response to the differential pressure inside the actuator body, turning the shaft clockwise or counter-clockwise in response to the pressure differential. External springs units are available for spring return models.

BENEFITS OF PNEUMATIC ACTUATORS

The use of compressed air (typically found in all industrial facilities) as the power source is the prime advantage for the use of pneumatic actuators. Additionally, pneumatic actuators have an advantage in suitability for different environments and can be used in extremes temperatures. They are preferred over electrical actuators in explosive, flammable and other hazardous areas because they do not require electricity (a possible ignition source) to operate. They do not create electrical fields or electrical noise since there is no electrical motor. Pneumatic valve actuators are faster opening and closing compared to their electric counterparts. Finally, they are low cost, lightweight, durable, require little maintenance (depending on quality) and there are a myriad of positioning controls, speed controls, and communications devices available for tailoring the actuator to the application.

DRAWBACKS OF PNEUMATIC ACTUATORS

While compressed air is the main reason for using pneumatic actuators, it can also be considered a drawback. For instance, pneumatic actuators can perform poorly when the air supply source is located at a distance, resulting in lag and slow response. Another drawback of pneumatic actuators is the additional cost for the compressed air system due to the requirement of dust filters and moisture removing dryers. These are required to ensure clean air is fed into the system.

APPLYING PNEUMATIC ACTUATORS

There are many aspects to the proper, safe, and efficient application of pneumatic actuators to valves and dampers. Sizing the power output (torque) being paramount. All valves and dampers have unique torque requirements. You must consider a threshold force for opening (breakaway), as the valve continues to move to its open or closed position, and then for seating. Matching the actuators to the valve type, and operating conditions is critical. Published torque curves must be reviewed and understood. Too little torque and the vale will not respond. Too much torque increases cost and can damage the valve. Spring return adds to this complexity. Considering all this, it is strongly suggested you always discuss any valve actuation requirement with an experienced applications expert. They will ensure the proper, safe, and cost effective mating of pneumatic actuator to valve or damper.
