For the new thermal power plant in Elabuga, gas compressor units have been shipped

2 September 2017

In the city of Elabuga (the Republic of Tatarstan) a new GTU-TPP is being built at the site of the Central boiler house. The generating equipment consists of four gas turbine units Solar of type Taurus 60 GS with a unit capacity of 5.6 MW and four hot-water waste-heat boilers. The installed electrical capacity of the station will be 22-23 MW.

The designer is LLC "Tatbelenergoproekt". The owner of the facility and the operating organization is LLC "PRP "TatEnergoRemont".

For GTU-TPP, ENERGAS will supply a comprehensive gas treatment system - a gas treatment unit (packaged gas purification unit - PGPU) and a booster compressor station. This process equipment will be put into operation by ENERGAS step by step.

The main elements of the PGPU are a gas purification system consisting of three filtration lines and a drainage module, and a two-line gas metering unit. Additional equipment is a continuous chromatograph (calorimeter) and a dew point measurer with sampling devices. 

In accordance with the project PGPU will carry out the following functions:

  • gas purification from solid particles and droplet moisture to the turbine manufacturer's design requirements;
  • collection of trapped liquid in a drainage tank with subsequent transfer to a mobile vessel or special transport;
  • gas flow measurement;
  • determination and recording of gas composition and its changes;
  • determination of calorific value;
  • dew point measurement.

After preliminary treatment, the gas flow is directed to the booster compressor station, including two screw-type units. The BCS compresses and feeds fuel gas to the turbines at the required design pressure of 1.65 MPa. The process scheme of the BCS also provides for the provision of a set gas feeding temperature to the GTU-TPP. 

The capacity of the comprehensive gas treatment system is 8,240 m3 / h. All units are automated; local ACS will be integrated into the APCS of the thermal power plant. Equipment version - container, block-modules are equipped with safety and life support systems. 

At present, after successful factory tests, gas compressor units have been shipped and are being transported to the construction site of GTU-TPP. The shop assembly of the gas treatment unit is on-going.
