Fuel gas production technology for the oil refining industry

Abstract

Reducing energy costs for production and reducing air pollution is one of the key tasks today. The main sources of atmospheric air pollution at oil refineries are: tubular heating furnaces - 50%; reactors of technological installations - 12%; flares - 29% and bitumen installations - 9%. Therefore, the development and implementation of methods to reduce harmful emissions and increase energy efficiency during fuel combustion is one of the main environmental objectives. In the process of oil refining, a large number of gas components of different potentials, pressures and homogeneity of the medium are formed. The forming gases are usually sent to the torch as a recyclable product, and the lack of energy resources is compensated by the use of liquid fuel or natural gas. Consequently, the task of better consumption of hydrocarbon gas is being formed with the possibility of reducing the consumption of liquid fuel and natural gas, i.e. increasing the energy efficiency of production, which leads to a reduction in harmful emissions into the atmosphere. To achieve these goals in the oil refining industry, on the example of LUKOIL-Volgogradneftepererabotka LLC, a plant for producing composite fuel gas for oil refining furnaces was developed and a new composite fuel gas based on hydrogen-containing and hydrocarbon gases of its own production was obtained. The composition of the composite fuel gas includes a "blow-off" hydrogen-containing gas, previously burned on a flare.
