FIELD: transportation; gas industry.
SUBSTANCE: invention relates to installations for draining and preparing LPG tank cars for maintenance and repair. LPG draining and tank car degassing plant includes a compressor unit connected to the buffer tank and tank cars connected to the nitrogen production unit by nitrogen supply line. Degassing unit consists of liquefaction units for catalytic oxidation, wherein the liquefaction unit is connected to the compressor unit by a line for supplying a mixture of LPG vapors and inert gas, to the inert gas supply line – by a line for supplying a lean mixture of LPG vapors and inert gas, and to the buffer tank – by a LPG discharge line. Catalytic oxidation unit is connected to the compressor unit by a line for supplying a mixture of LPG vapors and inert gas and is equipped with air supply and oxidation gas discharge lines.
EFFECT: prevention of atmospheric pollution by hydrocarbons and reduction of LPG losses.
