METHOD FOR REFINING CATCHER OIL PRODUCT OF SLOW CARBONIZATION DEVICE Russian patent published in 2007 - IPC C02F9/02 C02F9/10 C02F11/00 C02F11/18 

FIELD: technology for refining heavy oil.

SUBSTANCE: method for refining catcher oil product of slow carbonization plant includes thermo-exposure of water in sedimentation tank and refining of dehydrated catcher oil product on distillation plant. Catcher oil product of slow carbonization plant forming at stage of heating of coke chambers is sent to first sedimentation tank, where water is separated from it, and then sent for mixing with carbonization raw stock. Catcher oil product formed at coke steaming stage in coke chambers, is sent into second sedimentation tank, where it is mixed with light hydrocarbon fraction, water is separated from it and it is sent for mixing with carbonization raw stock, or for mixing with heavy oil leftovers for production of reduced fuel oil. Invention allows reduced amount of catcher oil product formed at slow carbonization device, increased output of light products (gasoline, diesel fraction) from slow carbonization device, decreased costs of transportation and refining of catcher oil product, decreased corrosion-erosion wear of equipment during transportation and refining of catcher oil product.

EFFECT: decreased volume of catcher oil product of slow carbonization device by 70-80%, increased output of clear oil products from slow carbonization device by 1,5%.
