METHOD AND APPARATUS FOR REPROCESSING OF GASEOUS RAW HYDROCARBON INTO SOLID PHASE POLYMERS Russian patent published in 2002 - IPC

FIELD: petroleum processing, petroleum chemical, gaseous and chemical industry. SUBSTANCE: method involves subjecting raw hydrocarbon to plasma chemical pyrolysis and plasma polymerization; discharging solid phase polymerization products from gas-plasma flow; purifying gas flow from unreacted raw hydrocarbon gases; pressurizing remaining inert gas and returning gas in the form of plasma flow to the stage of plasma chemical pyrolysis of raw hydrocarbon; discharging solid phase hydrocarbon polymers from two-phase flow. Inert gas or mixture of gases is used as plasma forming gas. Flow rate and composition of plasma forming gas are selected on the basis of measurements of chemical composition and consumption of raw hydrocarbon, which were separated before pyrolysis stage by radiation spectra and energy of electronically excited particles. Method further involves blowing plasma and raw hydrocarbon in the form of supersonic jets into reaction chamber at controlled rate of gas-plasma flow. Method and apparatus may be used for recovery of gaseous raw hydrocarbon, such as accompanying oil gases, gas condensates and other hydrocarbons by reprocessing them into solid phase products. EFFECT: increased extent of reprocessing of raw material into solid phase hydrocarbon polymers, including network polymers, and improved ecological safety of recovery process. 26 cl, 15 dwg
