Automation and Control Solutions for Hydrogen Production and Alternative Energy

Automation and Control Solutions for Hydrogen Production and Alternative Energy

One of the most important ways to reduce CO2 emissions in the chemical, oil, gas, paper, energy and transportation sectors is to generate and use green hydrogen from renewable sources. Electrolysis can convert electricity generated from wind, hydropower, or solar energy into hydrogen, which can then be stored in tanks, transported, and used whenever and wherever needed. Hydrogen's use is ubiquitous -  in CO2-neutral transportation, such as fuel cell vehicles, the chemical industry, steel manufacturing, and power plants. 

Process control is a primary and centralized function that responds to changes in operational consistency and load demand. Online monitoring and remote sensing advances, particularly for open-loop operations, are operated by controls and automation to develop actionable information for closed-loop control functions. In these situations, innovative automation solutions, such as those specified and implemented by Ives Equipment with flexible and integrated control technology, are required. 

With a focus on technical and economic feasibility for producing alternative energy and hydrogen fuels, Ives Equipment automation expertise provides exceptional control system experience that saves time and money and improves safety.

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

Self-regulating Heat Tracing Cable

Constant Wattage Heat Tracing CableThese self-regulating, cut-to-length cables are normally installed in commercial and light industrial applications, to maintain pipe temperature and/or prevent freezing. These heating cables are available in 120 and 240 voltages and are designed for use in ordinary or hazardous locations (with proper selections and application). Typical applications for this product are freeze protection and low watt density process temperature systems such as product pipelines, fire protection, process water and dust suppression systems.

MI (Mineral Insulated) CableConstant Wattage Heat Tracing Cable

Constant wattage heater cable is ideal for use in maintaining fluid flow under low ambient conditions. The product is used for freeze protection and process temperature maintenance systems such as product pipelines, process water, dust suppression systems, lube oil and condensate return.

MI (Mineral Insulated) Cable

MI Cable is a metal sheathed cable that uses a metallic conductor as the heating element. It is custom designed and fabricated for specific applications. MI Cable is a high performance, industrial grade heat tracing cable used for applications requiring high temperature exposure, immunity to stress corrosion, high maintain temperature, under tank heating (cryogenic tanks), high power output, constant power output over entire, rugged cable construction heater length, and extended heater life.

It is critical to consider the specific application requirements for any heat tracing application. The following checklist always needs to be clearly understood:

  • The mass and material of the item being traced
  • Insulation availability - type and thickness
  • Temperature to be maintained
  • Minimum ambient temperature
  • Minimum start-up temperature
  • Available supply voltage
  • The chemical environment - expose
  • Maximum intermittent exposure temperature
  • Electrical area classification

Always share your heat tracing requirements and challenges with a process heating specialist. There are many options and product variants from which to choose. A consultation with an expert can help direct you to the safest, most efficient, and most cost effective solution.

White Paper: Breakthrough Solenoid Valve Technology for Upstream Oil and Gas Heating Equipment

Low-temperature stainless steel fuel shutoff valves are usually utilized for on/off control of fuel gas
within gas fuel trains in process heating system burners. These systems are widely used by oil and gas firms as well by as original equipment manufacturers (OEMs) that produce gas heating equipment or burner management systems (BMSs) and controls in upstream oil and gas pipelines and tanks.

In recent years, a new generation of solenoid valve technology has been changing the shutoff valve game. Their modern designs provide pipeline and tank heating systems with robust, durable performance; safety; and regulatory compliance — all while increasing efficiency and productivity.

Many operators in North America and beyond are moving away from using pneumatically operated shutoff valves on their pipelines and tank heaters. They’re replacing them instead with valves introduced within the last decade by a few manufacturers — all based on solenoid shutoff valve technologies. White paper courtesy of ASCO.

2 Wire, 3 Wire, and 4 Wire RTD Sensor Connections

Industrial temperature transmitters
Industrial temperature
transmitters (courtesy of
Siemens)
Industrial temperature transmitters are devices that measure the temperature of a process and provide a measurable output over some desired temperature range. Industrial temperature transmitters primarily use either of two popular temperature sensors - the thermocouple or the RTD (resistance temperature detector). The RTD changes resistance as process temperature changes, while a thermocouple provides a changing micro-voltage with process temperature change. RTDs are inherently more accurate, but require excitation voltage. There are three style RTD's - 2-wire, 3-wire, and 4-wire.


Proper connections for all three types of RTD sensor to a user- configurable transmitter are shown in the following illustrations:

proper wiring of RTDs
Proper wiring of RTDs
It is critically important to note that the common connections shown by the symbols for 3- and 4-wire RTD sensors represent junction points at the sensor; not terminals jumpered by the technician at the time of installation, and not internal jumpers inside the transmitter. The whole purpose of having 3-wire and 4-wire RTD circuits is to eliminate errors due to voltage drop along the current-carrying wires, and this can only be realized if the “sensing” wire(s) extend out to the RTD itself and connect there. If the transmitter’s sensing terminal(s) are only jumpered to a current- carrying terminal, the transmitter will sense voltage dropped by the RTD plus voltage dropped by the current-carrying wire(s), leading to falsely high temperature indications.

Combustion Analyzer Adds Higher Level of Safety by Measuring O2, Combustibles, and Methane

WDG-VThe reliable identification of low combustion oxygen in a fired heater or boiler has always been critical to the effectiveness of the Burner Management System for proper control and safety.

Low emission burners and aggressive firing control points to achieve increased efficiency and emission reductions have driven the industry to tighter control measures. But tighter control measures also hold a greater potential for combustion events. Reducing the risk of a combustion event has become a priority and has led to the implementation of Safety Instrumented Systems (SIS). This additional layer of safety is added to the Basic Process Control System.

The WDG-V has been designed to provide an additional layer of safety with the measurement of excess O2, Combustibles and Methane and by using these measurements to ensure the safe operation of the Burner Management System.

WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as well as CO and methane levels. Information from the Gas Analyzer allows operators to obtain the highest fuel efficiency, while lowering emissions for NOx, CO and CO2. The zirconium oxide cell responds to the difference between the concentration of oxygen in the flue gas versus an air reference. To assure complete combustion, the flue gas should contain several percent oxygen. The optimum excess oxygen concentration is dependent on the fuel type (natural gas, hydrocarbon liquids and coal).

Lost Plant Air a Hidden Source for Energy Savings

Save energy costs
Save energy costs by reducing
consumption of plant air.
Industrial plant air is one of the easiest sources of power to transmit and use. It’s also one of the most costly to generate. Information from the United States Department of Energy (DOE) indicates a wide variety of factors determine the cost of compressed air. These include, but are not limited to, local electrical energy cost, efficiencies of electric motors and compressors, load factors, and service time.

Plant maintenance are becoming more aware of air leaks and the subsequent increases in cost to overcome lost power because of those leaks. One of the major culprits for lost air in a plant is the pneumatic control valve positioner and the air required to operate them. In a typical process plant, there could be hundreds of control valves. Each control valve uses a positioner to move the valve actuator, based on a set point signal from a controller.

Control valve with SIPART
Control valve
with Siemens SIPART
It is the control valve positioner where the greatest air consumption savings lies.

Years ago, when electricity was cheap and when valve positioners were first introduced, plant maintenance and engineering were not concerned with something called the “bleed rate” of the positioner. Over the years though, plant personnel lost track of bleed rate and pretty much forgot that a positioner is just part of the system and it operates on air. Today, a modern process facility such as a power plant, refinery, or chemical plant can have several hundred control valves with positioners. The combined air loss due to the positioner “bleed rate” can be significant.

SIPART positioners
Siemens SIPART positioners
An immediate solution to this problem is to replace the control valve positioners with modern, energy-efficient, low-bleed models. One model, the Siemens SIPART PS2 has a proven track record of providing substantial savings to large plants. In one case, a tabacco company that had 2500 positioners was planning on spending $600,000 on a new compressor to increase output. After reviewing the capabilities of the low bleed positioner and running some tests, the plant decided to implement a plan for replacing the positioners which mitigated the need for a new compressor.

The significant change in technology came with the adoption of the adoption of a piezo ceramic valve block in low bleed positioners. Traditional positioners used an I/P and spool valve which both leaked air. Over time the leaks from these two parts is significant.

Could you and your plant be in the situation where lost energy efficiency through leaky positioners is costing big bucks? If you’re even the slightest bit concerned, call in an applications expert now for a system review.

Compact Coriolis Flowmeter with NTEP Custody Transfer Approval

NTEP approval
NTEP approval for
custody transfer

When oil and gas are physically transferred from one operator to another, the term custody transfer is used to describe the transaction. It is understood as the transfer of fluid material defined by a metering device, at a given location, to another party. Custody transfer occurs at a variety of locations including from production platforms to ships, trucks, railcars, barges, and also at the final destination, such as the processing plant or refinery.

Accuracy is very important in custody transfer as both parties and instruments such as flowmeters must have approval by the organizations such as the American Petroleum Institute (API) or the National Conference on Weights and Measures (NCWM).

The National Type Evaluation Program (NTEP) is an evaluation program overseen by the National Conference on Weights and Measures (NCWM). Manufacturers who carry NTEP approval comply with local state and government regulations regarding transactions selling, purchasing, exchanging, custody transfer, or establishing the cost for services on based on weight.
