Delayed coking process

WebDelayed coking process is a thermal process which increases the molecular aggregation or association in petroleum-based residues or coal tar pitches leading to extended mesophase domains. This is achieved by holding them at an elevated temperature (usually 750 K–765 K) over a period of time (12 to 36 h).

Delayed coking is highly efficient in rejecting mineral solids and metals as well as some organic nitrogen and sulphur in the coke. WebThe delayed coker process is a batch process with multiple valve cycles within a 24-hour period. The high thermal reactions cause a “state change” in the hydrocarbon which can result in coke/asphaltene solidification in drum isolation valves. This failure mode is known as “coking up”. Another byproduct of this reaction is coke particulate. red lion application
