FREE PISTON STIRLING ENGINE FPSE
The FPSE is a hermitically sealed heat engine in which heating and cooling are applied externally to drive the engine.
Electricity is generated through a linear alternator attached to the piston which moves in a cyclic linear motion out of the high-pressure zone into the low-pressure zone.

The cyclic motion of the piston is driven by the pressure variations of the working fluid (helium) inside the engine, caused by the coaxial displacer periodically shuttling the working fluid from the heating zone to the cooling zone back and forth.

The FPSE is a completely maintenance-free power generation unit during its entire service life. This feature of the engine is due to the gas-dynamic coupling of the moving parts and absence of mechanical friction between the moving parts inside the engine, which excludes the need of a lubrication system and minimizes wear losses.

Heat is supplied to the engine from an external burner operating on low-pressure natural gas.

The service life of the engine is independent of the loads and the number of start-stop cycles.

EVOGRESS OFF-GRID POWER UNITS
The off-grid power unit EVOGRESS is an all-weather and anti-vandal power plant with the capability of supplying heat and power to facilities with constant electric power consumption in the range of 1 to 10 kW (short-term peak loads from 3 to 30 kW)

The standard configuration comes with the following main features:

1. The ability of connecting a renewable energy source (Solar &/or wind energy) to operate in parallel with the FPSE or independently.
2. A battery-inverter system for a guaranteed short-term peak power supply.
3. A separate heat supply circuit to the consumer from the FPSE cooling system.

The maximum efficiency of the power plant is achieved due to the realization of an optimization algorithm of the engine performance depending on the required constant power consumption (automated load control level from 10 to 100%)

Increased power output to power additional systems (Cathodic control, well monitoring, sand sensors, gas processing plant, etc.).
GAS PRE-TREATMENT SYSTEM AT GAS PRODUCTION FACILITIES
GAS FILTER SEPARATOR

Basic parameters:
Gravity type separator

The principle of operation of the gas filter separator.
After the ball valve (BV) opens, gas rises through the connecting pipeline (57x6 mm) at a speed of 0.007 m/s, up the body of the gas filter separator at a speed of 0.0004 m/s. Under the influence of gravitational forces, heavier particles of liquid and foreign matters fall into the lower part of the gas filter
separator and return to the gas well collector pipeline via the input pipeline. The filter element installed in the gas filter separator provides additional gas purification from the liquid phase.
