Preparation of fuel for gas reciprocating power plants

The most affordable form of electricity with minimum expense is supplied by autonomous power plants. As the main source of electric power gas-fueled reciprocating power plants can be used by industrial enterprises, depots, agricultural complexes and a number of social facilities: residential buildings, shopping centers, hotels, service stations, health centers, hospitals. Gas reciprocating power plants are normally used at sites requiring high reliability of power supply.

Gas engines operate on different kinds of combustible gases: metallurgic gases, biogases, landfill gases, coal mine gas, associated petroleum gas.

If you decide to switch over to electricity from your own gas reciprocating power plant, you need to assess the costs, consider the load, calculate the cost of production and finally resolve whether the construction is expedient or not. The advantages are low cost of electricity and heat, quick payback.

Gas piston generators are designed for continuous operation, are reliable and low-toxic.

Autonomous power plants can be of varying capacity. When the rated capacity per unit is less than the capacity required, two or more units operating parallel and isolated can be used. The use of two engines operating on gaseous and liquid fuels is possible. Precise data on the unit’s makeup can be obtained in the design process. The power unit can function both as an autonomous power source and in parallel with other power installations.

However, one must understand that the reliability and low operating costs are provided first of all by the quality of the which is delivered to a gas reciprocating power plant. Lured by the prospect of almost free electricity for one’s needs due to combustion of byproducts and environments which in fact are production wastes, power engineers do not emphasize the preparation of such media for its consumption at gas piston units.

The use of gas reciprocating power plant at -extracting enterprises could be hold up as an example. The consumption of associated petroleum gas for power generation in contrast to its useless flaring is undoubtedly a great achievement for and gas production industry. However, as practice shows, in most cases APG causes problems by the consumption at gas reciprocating power plants.

When testing our equipment at one of the -extracting enterprises we were tasked to prepare the gas for consumption at gas reciprocating power plant of the U.S. production. Untreated APG caused a constant machinery breakdown. And no wonder, except that the APG was heavily watered (about 20 g / m ³), it contained a large number of very fine inclusions, which were taken for a finely dispersed “ dust” by the producing people. These inclusions were not filtered off by regular filters with filter fineness equal to 1 micron, but flowed together with the to the gas piston power unit, where adversely affected the equipment and coked in the piston block.

After these particles were filtered off at our equipment together with moisture and liquid petroleum fractions, the inclusions were found to be not small droplets but polymer particles, similar to fine sand, formed by the interaction of salts with petroleum products under the pressure and temperature.

Laboratory of filtering technology “Cribrol” delivers a high-quality and low-cost equipment with low operating costs on the basis of a specially developed filtering material for the preparation of APG to be consumed by gas reciprocating power plants, as well as for other purposes. The equipment has been tested in a production environment.
