  • Patent number: 10081766
    Abstract: A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.

  • Patent number: 10076722
    Abstract: Provided is an NMP recovery system 1 for causing NMP-containing gas to contact NMP-absorbing water, including: fillers (10A) to (10D) that are permeable to the water and hold the water, wherein the permeated water moves according to gravity to flow out from the fillers; an NMP-containing gas distribution unit (30) for distributing the NMP-containing gas so as to cause the NMP-containing gas to contact the water held by the fillers (10A) to (10D); and a water distribution unit (40) for distributing the water so as to make the water permeate through the fillers (10A) to (10D). In the fillers (10A) to (10D), the NMP-containing gas is made to contact the NMP-absorbing water. Accordingly, NMP in the NMP-containing gas is absorbed in the water, so that the NMP is separated from the NMP-containing gas.
