Computational Studies of Increasing the Energy Efficiency of a Gas Piston Plant Running on LNG by Enriching the Fuel-Air Mixture with Oxygen

In this paper, the object of the study is a power complex, which includes a set of several circuits, to provide electricity to settlements or human life objects. The scheme of this complex consists of the main circuit (gas piston power plant) and auxiliary power plant (air separation unit (ASU)). Liquid methane is used as the main fuel. Calculations of the main circuit in cases of standard and modified (10 % and 20 % additional addition of oxygen) fuel-air mixtures were carried out, also thermodynamic calculations of the air separation unit circuit, auxiliary LNG regasification circuit were performed.
