METHOD OF TRAPPING OF THE HARMFUL GASES EJECTIONS FROM THE REACTORS OF CARBONIZATION Russian patent published in 2007 - IPC B01D3/16 C10B55/00 

FIELD: oil-processing industry; methods of trapping of ejections of foul gases from rectors of a carbonization.

SUBSTANCE: the invention is pertaining to the field of the oil-processing industry and may be used at trapping the harmful gases ejections from the reactors of carbonization. The method provides for the preliminary separation of the products of the heating-up of the reactors, the coke steaming and cooling in the additional rectifying column with extraction of the intermediate fractions guided into the basic rectifying column, the water condensate and the gas. At that for separation into the additional rectifying column they feed the products of the heating-up with the flow temperature below 240°С and the products of the steaming and cooling with the flow temperature of 150-240°С, and as the intermediate fractions gate out the low quality fractions at -180°С, 110-180°С and +180°С. The products with the flow temperature of above 240°С may be guided directly to the basic rectifying column, and the products with the flow temperature below 150°С - in the separator. It is preferable to conduct separation in the separator at the temperature of 80-140°С and duration of 1-3 hours. The method allows to raise the quality of separations of the trapped harmful ejections, in particular, to reduce the share of petroleum in the water condensate and to decrease the petroleum products losses and to increase efficiency of the process of trapping, as well as improve the ecological indexes of the process of the retard carbonization.

EFFECT: the invention ensures the improved quality of separation of the trapped harmful ejections, reduction of the share of petroleum in the water condensate, the decrease of the petroleum products losses, the increased efficiency of the process of trapping, the improved ecological indexes of the process of the retard carbonization.
