METHOD OF RETARDING OF PETROLEUM RESIDUE COKING Russian patent published in 2005 - IPC

FIELD: petroleum refining industry; petroleum residue coking retarding method.

SUBSTANCE: the invention is pertaining to the field of petroleum refining industry and is aimed at improvement of operation of installation of petroleum residue coking retarding. The method includes a preliminary heating of the original crude, its mixture with a recirculator - a heavy gas-oil of a coking with production of a secondary raw material and heating it up to the temperature of coking in the reactor with formation of a coke and distillate products of coking and preparation of the reactor. In case of failure of one of the reactors the thermal formation of the secondary raw material is cooled and is directed for separation into the rectifying tower, while in the operating reactor they conduct preparation and the following cycle of a coking is exercised in the same reactor. The invention allows by recovery of the process of coking to raise its efficiency.

EFFECT: the invention allows upgrade the coking process efficiency.
