LOWER OLEFIN PRODUCTION PROCESS Russian patent published in 2003 - IPC

Abstract RU 2206598 C1

FIELD: petrochemical processes. SUBSTANCE: process for production of lower olefins via pyrolysis of hydrocarbon feedstock in tubular furnace at 790-850 C in presence of water steam is characterized by that hydrocarbon feedstock is a mixture of ethane, propane, and butane (3-71, 13,38-28.95, and 2.26-71.45 wt %, respectively), furnace residence time is 0.35-0.4 sec, and pressure in pyrolytic coil inlet and outlet is 3.5-4.4 and 1.0-1.1 bar, respectively. EFFECT: increased yield of ethylene and propylene and extended pyrolysis feedstock resource. 5 cl, 1 tbl, 10 ex
