Process equipment

Compressor package

Compressor packages are the primary process equipment of a gas compressor plant (GCP). They consist of centrifugal blowers driven by a gas turbine or electric motor and compressors powered by gas-fuelled engines. These process systems are capable of power output of up to 15 MW. High performance GCP are designed to be used with a centrifugal blower driven by a gas turbine power plant with capacity of 25 MW or more.

The GCP process complex includes a compressor yard, gas purification, drying and cooling plants, auxiliary power plant (step-down substation for electricity-powered GCPs), telecommunications facility and maintenance and repair facilities.

GCPs have a control room. Compressor yard systems are controlled either from local control panels or from a central control panel, depending on automation solutions adopted on site. A fully automated GCP is controlled remotely from a central control room.

A gas compressor plant is a system that steps up natural gas pressure in the course of extraction, transfer and storage of gas. In terms of their intended use, GCPs are classed into main (booster) units serving main gas pipelines, intermediate GCPs on main gas pipelines, underground storage GCPs and gas re-injection GCPs.

A GCP’s primary process parameters are its performance, power, gas compression and maximum operating pressure.

Air plant

Compressed air is used as instrument air in many process and municipal applications. Air plant compressor design depends on the required air supply and purity of air at maximum operating pressure. Compressors can be integrated with adsorption or refrigerated air dryers, oil-water separators, level-controlled condensate drain systems, dew point control equipment, and piping.

API / CPI Separators

API oil-water separators and corrugated plate interceptors (CPI) enable separation of suspended solids during oil-water treatment and gravity separation of oil droplets from emulsions based on the difference in specific gravity between phases (oil, solids, water). API and CPI separators are often used for pre-treatment to decontaminate wastewater before it is fed into flotation facilities.

Sodium hypochlorite dosing systems

Sodium hypochlorite is a chemical compound that is highly relevant for domestic and industrial applications because of its diverse useful properties and reasonable cost. Since it is rather unstable in its base crystalline state, it is normally stored and transported in the form of aqueous solutions. It is therefore most expedient to use specialised dosing pumps to handle and dose sodium hypochlorite.

Even at low concentrations, sodium hypochlorite solutions (also known as sodium perchloric acid or NaOCl) can quickly neutralize most commonly encountered pathogenic microorganisms, including many bacteria and fungi. Exposure to NaOCl over a longer term eliminates organic toxins and inhibits reproduction of small aquatic flora. These properties make the compound best suited for disinfection of domestic and industrial facilities.

Its many applications include decontamination of natural water to be supplied as potable water to water supply systems of settlements; disinfection of water in private and public pools, small urban water bodies, fountains; decontamination of environments made potentially pathogenic by urban and industrial wastewater; disinfection measures in polyclinics, hospitals, and other public buildings; bactericidal treatment of pipeline systems and pumping units at food industry enterprises; preventive treatment of grain and agricultural feed; and other decontamination activities for various containers, premises, materials, etc.

Membrane wastewater treatment plants

Membrane bioreactor (MBR) water treatment process combines complete biological treatment (denitrifier – aerotank nitrifier) with activated sludge together with mechanical membrane filtration. The MBR is used to separate activated sludge and treated water. The membranes are designed for treatment of highly contaminated industrial wastewater.

Advantages of membrane bioreactors over traditional wastewater treatment plants:

The degree of water purification is significantly higher at 99.99%, which makes it possible to discharge wastewater into open natural reservoirs of all categories without additional treatment.

Pressure Vessels

Pressure Vessels are containers which are designed to hold liquids, vapors, or gases at a pressure substantially higher or lower than the ambient pressure that can be hazardous. We can offer our clients the design, fabrication and erection of pressure vessels with the capacity of 1m3 to ANY custom-required size according to API, ASME, EN, DIN, ГОСТ standards. There are specialized application pressure vessels such as reactors and regeneration vessels, however most correspond to the three common types: storage vessels, heat exchangers and process vessels. We can offer you any type of pressure vessels with or without coating at your choice and specific requirements.

Industrial pumping equipment

We offer industrial pumping equipment for a wide range of applications. We embrace cutting-edge technology and strive for the best possible reliability and optimal energy efficiency.

Groundwater treatment plant

Industrial water treatment plants have a wide range of applications. Water treatment is used to make water compliant with production requirements or suitable for domestic and drinking water supply. Industrial water treatment plants are chosen based on chemical analysis results and production requirements for water as well as the required flow rate.


A nitrogen membrane system is an efficient alternative to PSA systems. This design uses hollow fibre membranes with high selectivity for nitrogen separation. These semi-permeable layers are composed of flexible cylindrical filaments with pore sizes ranging from 0.03 to 10 microns.

Dry compressed air is fed onto the material to separate the nitrogen gas that is present in the cylindrical vessel. The nitrogen membrane allows N2 to pass through and keeps out oxygen, inert gases, water vapour and other admixtures. Membrane selectivity depends on the pore size. Membrane-based nitrogen generators enable nitrogen purity of up to 99.99%.

Emergency flame arresters

Atex certified breather valves, vents and flame arresters of different types according to the combustion process and by type of installation. The working principle of flame arrester is flame quenching in small gaps. The gap width and the gap length of the flame filter of flame arresters determines its extinguishing ability. The narrower and longer the gap, the greater the extinguishing effectiveness. The wider and shorter the gap, the lower the pressure loss.

Ventilation system for gas venting

Emergency gas vents release into the atmosphere the gases discharged by automated emergency safeties and relief valves of gas control units and automatic gas distribution stations. They are also used to disperse petroleum product vapors at refineries. These vents can have input pressure ranging from low (up to 0.1 MPa) to high (up to 16 MPa) and be equipped with flame arresters.

Measurement and accounting of gas consumption

Industrial flow meters are used for commercial metering of gas volume during operation of various gas supply systems and gas distribution stations of various capacities.

Volume correctors automatically calculate the gas compressibility coefficient and make corrections based on the information received from pressure and temperature sensors as well as the base gas parameters.

Gas chromatographs are designed to analyze gas composition and determine density and calorific value of natural and associated petroleum gas.
