Late stage of coking
Thread Content
With a turnaround time of 39 hours, the manager ordered that the flaps on the bridge pipe be closed once the waste gas had been completely removed. The question is: why has the waste gas been completely exhausted a few hours after coking? To put it directly, after how many hours of coking can the flip plate be closed?
It usually takes about 24 hours to drain the raw gas at the late stage of coking, after which the flap can be closed. The specific time may vary depending on the process and equipment; please refer to the actual operating procedures. .
