METHOD AND PLANT FOR SLOWED-DOWN COKING WITH REDUCED CYCLE DURATION

摘要

FIELD: coking. SUBSTANCE: method is realized by heating of coke drum external surface section before coke drum filling with initial hot coking material. Said external surface section is located neat point of fastening of drum shell to bearing support in the form of shirt. Such heating of drum external surface allows reduction of heat stresses arising in welds fastening support. to drum. EFFECT: reduced plant cycle duration for slowed-down coking. 7 cl, 6 dwg
