WebOct 1, 2005 · Delayed coking evolved steadily over the early to mid 1900s to enable refiners to convert high boiling, residual petroleum fractions to light products such as gasoline. Pound for pound, coking is the most energy intensive of any operation in a modern refinery. WebThis patent describes a delayed coking process comprising of a coker fractionator, coker heater and coke drums wherein a coker fresh feed consisting of petroleum hydrocarbon derivatives from various refining processes is thermally processed in the heater and coke drums producing green coke, hydrocarbons and gases. ...
Webdelaying the coking until the cracked product entered the drum, and the use of two drums enabled the delayed coker to operate on a continuous basis. The Modern Delayed Coking Process The delayed coker is the only main process in a modern petroleum refinery that is a batch-continuous process. The flow through the furnace is continuous.
