METHOD OF REGENERATION OF ZEOLITE OF DEHUMIDIFICATION AND CLEANING PROCESSES OF NATURAL GAS FROM SULFUR COMPOUNDS Russian patent published in 2000 - IPC

FIELD: adsorption cleaning of natural, oil and other hydrocarbon gases; gas, oil and petrochemical industries for regeneration of zeolites of dehumidification and cleaning processes of gases from sulfur compounds. SUBSTANCE: method includes successive blowing of zeolite with heated gas of regeneration and cooling, for example natural gas properly dehumidified and cleaned from sulfur compounds; cooling process gas is subjected to low-temperature condensation and rectification (at separation of hydrocarbons C2 and higher), residual sulfur compound and moisture before blowing zeolite; remaining methane fraction is compressed and cleaned from compressor oil vapor and after blowing zeolite, it is additionally heated and is used as regeneration gas. Methane fraction is cleaned from compressor oil vapor by blowing through used zeolite layer whose adsorption capacity is worked out in main process. Saturated regeneration gas is used as fuel gas. EFFECT: improved quality of regeneration of zeolite; increased service life; additional production of useful products: ethane fraction and wire fraction of light hydrocarbons. 2 cl, 1 dwg, 2 tbl
