Separation processes
  • Oil and gas separators
  •      ::. Design of separation train
  • Control safety systems for slug catcher
A slug catcher is a device used in the oil and gas industry to remove any liquid slugs (i.e., a large volume of liquid that enters the pipeline intermittently) from a natural gas stream. The slug catcher is typically a horizontal vessel located downstream of a gas/liquid separator and upstream of the gas processing equipment. The device works by slowing down the gas velocity, allowing the liquid slugs to settle to the bottom of the vessel. The liquid is then drained from the vessel, and the gas is sent for further processing. Slug catchers are an important part of the gas processing system as they help to prevent damage to downstream equipment and ensure safe and efficient operation of the plant.
  • Valves
Oil and gas valves are specialized valves designed to control the flow of oil and gas in various stages of the production process. These valves are typically made of high-quality materials such as stainless steel, brass, or bronze to withstand the high pressures and corrosive environments of oil and gas applications. There are many types of valves used in the oil and gas industry, including ball valves, gate valves, globe valves, check valves, and butterfly valves. Each type of valve has its own specific function and is used in different stages of the oil and gas production process. Ball valves are commonly used in oil and gas applications because of their quick quarter-turn operation, high reliability, and ability to provide tight shut-off. Gate valves are used for their ability to provide full bore openings and low-pressure drops, making them ideal for pipeline applications. Globe valves are used in applications that require precise flow control, such as in refineries and chemical plants. Check valves are used to prevent backflow in pipelines and other applications. Butterfly valves are used in applications that require high flow rates and low-pressure drops. Overall, oil and gas valves are essential components in the production and transportation of oil and gas, and their proper selection, installation, and maintenance is critical to ensuring safe and efficient operations.
Special separators

Equipment for oil and gas/ refineries:
  • Heat exchangers
  • Tube bundles
  • Vessels
  • Columns
  • Burners

Heat exchangers:

Heat exchangers are determined for universal use of heat exchanging, they can work as coolers, heaters, condensators, generators, evaporators etc. We deliver them of various designs and of various materials, e.g. fixed tubesheet, with floating head, with compensator in the shell, clad tubesheets, as per projection settings. We are also able to provide complete design including thermal design of the heat exchanger.
The columns are designed as per project requirements, can be delivered including inner parts and plates of columns.
Specially designed apparatuses that are determined for given operation, e.g. agitated reactors. They can be delivered of various materials, CS, SS + for example rubberizing or another surface finish by reason of resistance to used medium.
The burners are determined for chemical and petrochemical industries, both for domestic rafineries and plants engaged in oil products processing and also for petrochemical complexes in former USSR, Iraq and Syria
  • gas burners
  • oil burners
  • oil-gas burners
Pipelines, monitoring and protection

We provide corrosion inhibitors. Corrosion inhibitors are chemicals that can be added to pipelines to prevent or reduce the rate of corrosion. There are several types of corrosion inhibitors available, including:

1. Organic inhibitors: These are compounds that contain organic molecules such as amines, imidazolines, and quaternary ammonium salts. They work by adsorbing onto the metal surface and forming a protective film that prevents further corrosion.
2. Inorganic inhibitors: These are typically metallic compounds, such as zinc or calcium salts. They work by forming a protective layer on the metal surface that prevents further corrosion.
3. Mixed inhibitors: These are a combination of organic and inorganic inhibitors. They offer a broader spectrum of protection against corrosion.

The choice of corrosion inhibitor will depend on factors such as the type of metal used in the pipeline, the nature of the fluid being transported, and the operating conditions of the pipeline. It is important to note that while corrosion inhibitors can be effective in preventing or reducing corrosion, they are not a complete solution. Regular maintenance and monitoring of the pipeline are still necessary to ensure its long-term integrity.
