Patent number: 5076893Abstract: The present invention relates to decoking of a residual oil delayed coke reactor. When decoking, the roller of the flexible pipe winch is rotated to cause the flexible pipe to vertically ascend or descend in the coker wherein the high pressure water rotates the turbine blades of the turbine-reductor which brings the drilling and cutting combination unit into rotation so as to drill a through hole in the coke accumulation and then conduct the decoking operation. The drilling and cutting combination unit is equipped with a pressure control unit so that switchover of the drilling and cutting operations can be automatically performed. The present invention eliminates the use of a derrick, resulting in significant savings in time, quantity of steel, capital investment, and equipment required to facilitate the decoking process and enhance decoking efficiency.Type: GrantFiled: August 16, 1990Date of Patent: December 31, 1991Assignees: LuoYang Petrochemical Engineering Corporation SINOPEC (LPEC), Institut Francais du PetroleInventors: Wuwei Tong, Deyu Sun, Qingyuan Zhang, Lielai Wu, Shicheng Zhou, Shande Yu, Daoji Du, Shili Yang
