Abstract

The invention discloses a coking-coking full range hydroprocessing combined process method. A simplified fractionating tower is arranged at a coking part, and a heat-exchange evaporation section and a condensing fractionation section are respectively arranged at the lower part and the upper part of the simplified fractionating tower. Oil gas produced by the coking reaction enter the simplified fractionating tower from the lower part, and flows upwards into the condensing fractionation section at the upper part of the simplified fractionating tower after being leached and exchanging heat with coking material, most of the oil gas is liquefied in the condensing fractionation section and led out of the simplified fractionating tower, a condensate led out of the simplified fractionating tower undergoes the hydroprocessing after separating out water, and a hydroprocessing product is separated into hydrogenated gasoline, hydrogenated diesel oil and hydrogenated wax oil. The method organically combines the coking technique and the hydroprocessing technique to simplify the coking technical process and improve the economical efficiency and reliability of the hydroprocessing part in the meanwhile.

Description

technical field

[0001] The invention belongs to the combined technology of thermal processing technology and hydrogenation treatment technology. Specifically, it is a combined process technology of delayed coking process and coking whole distillate hydrotreating process. Background technique

[0002] At present, the trend of heavy and inferior crude oil is obvious, and with the development of the economy, the demand for light distillate oil, especially clean light distillate oil, is gradually increasing. Therefore, it is necessary to process inferior and heavy raw materials into clean light distillate oil. quality distillate products. Coking is a commonly used method to convert inferior heavy and residual oil to light. Its advantages are low investment and wide source of raw materials. The main disadvantage is that the liquid yield is low, and the quality of liquid products is poor, which requires further processing.

[0003] In the coking process and subsequent product pr...
