The fencing of the structure is made of building sandwich panels with pressed insulation made of non-combustible material, which complies with fire safety standards. The unit-box is equipped with a fire and security alarm system. The units provide for local and remote measurement of technological parameters. The plant equipment is controlled from the station automatic control and regulation system.

Climatic performance will be determined depending on the region of construction.

Advantages

• unit-modular design and maximum factory readiness allow the installation of equipment in a short time;

• simplicity and flexibility of technological process regulation;

• compactness of the installation, all Fuel and Impulse Gas Treatment Plants equipment is placed in a single monounit, which allows to reduce the construction site and reduce construction and installation work, which leads to a reduction in capital and operating costs of the Customer;

Part of the equipment

Fuel and Impulse Gas Treatment Plants generally includes:

• gas purification unit from liquid and mechanical impurities;
• impulse gas drying unit;
• gas heating unit;
• fuel gas reduction unit for in-house needs;
• gas metering unit (measuring unit);
• unit of the automated control system, which has the ability to communicate with the ACS of the compressor station to transmit information and receive control commands.

Principle of operation

FIGTUs are designed to prepare and supply gas with the required characteristics and quality to consumers located at the site.

The gas from the inlet manifold enters the gas purification unit (filter-separators), which includes at least two apparatuses operating in parallel.

The content of impurities is determined by the customer's requirements specification.

The gas flow metering unit is designed to measure the gas flow through the FIGTU, consumed for the in-house needs. The metering unit consists of two lines: working and bypass. A gas flow meter is installed at the metering unit, designed for commercial metering of gas consumption for in-house needs.

The gas flow measurement error should be no more than ±1%.

If necessary, the gas enters the gas supply pipeline to the gas heaters to heat the fuel gas before reduction and ensure the required gas temperature range at the gas compressor inlet. The gas is heated through an intermediate heat carrier.

The fuel gas is reduced to a pressure determined by the type of gas compressor units used at the compressor station. It is planned to install two threads (one working second reserve). The installation of two reduction lines provides a guaranteed gas supply of the required pressure to the GTU. In normal mode, gas is supplied through one of the reduction lines, the second line is in standby mode.

The impulse gas preparation unit is intended for the preparation of impulse gas for the control of pneumatic actuated valves of the compressor station and the connection unit. The unit provides dehumidification of pulsed gas at dew point down to minus 55 ℃. The unit is delivered as a single unit complete with an automation and control system. The installation parameters are monitored and controlled by FIGTU ACS .
