摘要： A method and apparatus for improving a hydrogen utilization rate in a hydrogenation hot high-pressure separation process. Hydrogenated distillate oil, a gas product and hydrogen pass through an inertia separation distributor arranged in an inlet of a hot high-pressure separator under high pressure for preliminary gas-liquid separation, and a gas phase goes to a subsequent system; a liquid phase goes into a hot low-pressure separator. Releases a part of low-pressure separated gas (mainly hydrogen) after preliminary separation through an injection flash separator in the hot low-pressure separator, and is divided into a gas phase and a liquid phase based on gravitational settling; hydrogen and some micro bubbles that are still dissolved in hot low-pressure separated oil under the pressure are separated from the oil through a centrifugal degassing device; the gas phase exits from the apparatus after carried liquid droplets are removed completely through hydrocyclone separation or coalescence separation, and distillate oil goes to a subsequent facility.

摘要： This invention involves a method and a device for enhanced oil-water separation and desalination in a low-pressure separator. The water-containing oil is mixed with desalted water in a countercurrent way at the entrance, wherein the desalted water accounts for 0-1% of the water-containing oil by volume. The resultant oil-water mixture then enters a T-shaped liquid-gas separator (3) for degassing treatment to quickly separate gas from the mixture. In a low-pressure separator, the oil-water mixture flows, from left to right, to a flow conditioner (4) to uniformly distribute the mixture in the transverse section, and then flows to a hydrophilic droplet agglomeration module (5) and a CPI fast separation module (6) to separate water from oil, wherein part of the separated water is discharged and the oil with a trace of water (0-0.01%) passes over a partition (18) to a deep separation segment. The oil is subjected to deep water removal by a conjugated fiber water removal module and then discharged, and the water captured by the conjugated fiber water removal module is subject to a conjugated fiber oil removal module for deep oil removal and then discharged.

摘要： The present invention relates to a device for liquid degassing by means of the swirling or the centrifugal field coupled with the pressure gradient field. This device comprises a cavity. The cavity is furnished with an inlet for liquid gas, an outlet for gas phase and an outlet for gas liquid phase. The outlet for gas phase is inserted into the cavity through the upper surface of the cavity, wherein the depth of the insertion is around 0.1-3 times of the maximum diameter of the cavity. Specifically, the outlet for gas phase is realized through an overflow pipe with the diameter gradually increasing from the bottom to the top. The end of the overflow pipe is further furnished with a bell mouth. The advantages of the present invention are: The present invention designs the structure of an inverted cone shaped outlet for gas phase which is inserted into the cavity of the swirling device. The present invention makes full use of the impact of pressure gradient in the cavity on the solubility of gas in liquid and combines the centrifugal field and the pressure gradient field to remove the gas entrained with liquid while the dissolved gas is removed under the inlet partial pressure.

摘要： The present invention relates to a method and a device for deep oil removal from wastewater containing a low concentration of wasteoil. Wastewater containing a low concentration of wasteoil enters the device via an inlet and passes through a flow conditioner, causing the fluid to become uniformly distributed. Then, by means of a layer of oleophilic-hydrophobic fibers and hydrophilic-oleophobic fibers woven in a certain manner, a trace of oil droplets are captured and then coalesce and grow on the layer, and a trace of oil-in-water emulsion is demulsified and separated on the layer. Finally, by means of corrugation-enhanced sedimentation and separation, the oil droplets coalesce and grow and are then separated rapidly. The invention also provides a set of devices for implementing the method, having several parts such as a housing, a feed pipe, a flow conditioner, a fiber coalescence layer, a corrugation-enhanced separation layer, and a level gauge. The present technique is highly efficient in separation, consumes little power, and can operate continuously for a long period of time. Thus, this technique can be widely used in processes for treating wastewater containing a low concentration of wasteoil.
