PML has worked with many refiners to develop solutions to some of the most difficult instrumentation and control problems in coker applications. Our team hcan help you streamline maintenance and reduce unplanned downtime caused by asset reliability issues.

The delayed coking process in a refinery is used to break down vacuum residual hydrocarbons into shorter hydrocarbon chains that can then be hydro processed into sellable products. The coker generates high temperatures and high vibration, and produces erosive petroleum coke particles that can be hard on instrumentation and erosive to piping and valves.

  • Rely on trusted solutions for difficult instrumentation and control problems

  • Avoid downtime and lost revenue

  • Protect against erosion to instrumentation

Distillation and Fractionation

Distillation and Fractionation

PML works to help you meet product specifications, minimize energy usage, and improve throughout to optimize your fractionator and distillation processes.

One of the biggest challenges of separation processing is to obtain the desired yield of sidecuts and products that meet specifications while maintaining the lowest cost and energy usage possible. PML team has developed control solutions for both fractionators and distillation units, ensuring the proper process control adjustment and selection of instrumentation. Let’s optimize fractionator and distillation processes to minimize disturbances, improve recovery, and increase refinery efficiency.

  • Minimize disturbances

  • Increase refinery efficiency

  • Improve recovery

Fluidized Catalytic Cracking

Fluidized Catalytic Cracking

With high temperatures and severe conditions, using the proper field instrument measurements is essential to understanding how the process is performing at any given moment. PML’s experts have developed measurement and control solutions to ensure the unit is monitored safely, and is optimally controlled.

Fluid Catalytic Cracking (FCC) units produce refined products, such as gasoline, distillates, and olefins, through highly controlled and selective reactions in the presence of heat. The FCC unit is a critical element in the refinery and provides feedstock to several other units. It is essential that reliable, highly accurate flow and pressure control are maintained to ensure safe FCC unit operation and unscheduled shutdowns are minimized to avoid significant financial impact. Let’s reduce steam usage while maintaining quality with improved distillation control.

  • Maintain reliable and highly accurate flow and pressure control

  • Avoid significant financial impact

  • Ensure safe FCC unit operation and unscheduled shutdowns are minimized

Gas Plant

Hydrogen Plant

Hydrogen Plant

Hydrogen is essential to the hydrocracking and hydrotreatment processes used to create high value and clean products, and for the reduction in compounds that are harmful to the environment. Additionally, with the quality of crude slowly declining, the efficient use of hydrogen is essential for the profitability of the refinery.

The efficient use of hydrogen is critical in refinery operations, and you need to ensure uninterrupted and safe operation of your hydrogen supply. PML understands how important it is that the supply of hydrogen to the refinery is extremely reliable and safe. Our best-in-class technologies and solutions ensure that your hydrogen supply remains uninterrupted and is operated in a safe and reliable manner to reduce risk to your personnel and assets

Sulphur Recovery

Sulphur Recovery

The sulfur plant is a key unit that can limit the output of the entire refinery, and up-time and safety are essential to maintain refinery throughput. The Sulfur Recovery Unit (SRU) capacity dictates what types and volumes of high sulfur feed stocks can be processed. A small gain in capacity in the SRU can yield significant profit for the refinery.

Our world-class technologies help to reduce environmental concerns by maintaining the proper ratio of H2S to combustion air to avoid the release of excessive H2S or SO2. Additionally, our experts at PML ensure the sulfur recovery process is executed to meet the highest reliability and safety standards.

  • Maintain uptime
