METHOD OF CONDUCTING THERMAL CRACKING OF HIGH-VISCOSITY OIL STOCK

FIELD: petroleum processing. SUBSTANCE: method consists in mixing raw material with light hydrocarbon fractions, heating mixture in pipe furnace, and aging of mixture in reaction chamber, followed by separation of products into gas, gasoline, and cracking residue. Distinguishing feature of method is...

Beschreibung
Zusammenfassung:	FIELD: petroleum processing. SUBSTANCE: method consists in mixing raw material with light hydrocarbon fractions, heating mixture in pipe furnace, and aging of mixture in reaction chamber, followed by separation of products into gas, gasoline, and cracking residue. Distinguishing feature of method is that mixture is heated in pipe furnace at 455-465 C and aged in reaction chamber at 420-425 C for 4- 15 min. EFFECT: decreased viscosity of cracking residue and increased overhaul life of thermal cracking plant. 1 tbl, 7 ex
