Process and device for treating catalyst discharged from bubbling bed hydrogenation of residual oil // 2607764
FIELD: chemistry.SUBSTANCE: invention relates to a method for treating a catalyst discharged from bubbling bed hydrogenation of residual oil. Method comprises following steps: (1) adjustment and control to reduce viscosity, wherein catalyst discharged intermittently from a bubbling bed hydrogenation reactor for residual oil, is adjusted for storage and then discharged continuously, subjected to temperature adjustment by adding water, such that viscosity of oil adsorbed on surfaces and inside pores of discharged catalyst particles is reduced, and flowability of adsorbed oil on surfaces and inside pores of the discharged catalyst particles is improved; (2) desorption and separation by rotational flow, wherein adsorbed oil is desorbed and separated from surfaces and inner pores of discharged catalyst particles by a flowing shear force from a rotational flow field; (3) separation and resource utilisation of three phase oil-water-catalyst, wherein oil/water/catalyst mixture produced from desorption and separation by rotational flow, is subjected to three-phase separation, achieving recovery of oil, recycling of water obtained by separation, and full recovery of solid particles obtained by separation. Invention also discloses a device for implementation of method.EFFECT: technical result consists in reduction of cost of treatment, simplified process, higher oil recovery factor, reduced tendency to formation of secondary sources of contamination.10 cl, 1 dwg, 1 ex

ethod of reducing content of organic chlorides in oil // 2605601

Method includes preliminary dehydration and degassing of oil, heating oil with extraction of organic chlorides, discharge of purified oil. Preliminary dehydration is performed to oil water content of not more than 1 %, heating is carried out to temperature, which enables to distill a fraction from oil in a rectification column, said fraction containing organic chlorides and boiling at atmospheric pressure in temperature range from initial boiling point to 204 C, and part of distilled fraction - reflux is used for irrigation of rectification column, volume of reflux is defined empirically depending on structural features of said column and oil volume, fed for distillation.EFFECT: proposed method enables to obtain purified oil with content of organic chlorides of less than 10 ppm.1 cl, 1 dwg, 1 ex
ethod of gas-saturated oil stabilisation // 2465304
FIELD: oil and gas production.SUBSTANCE: invention relates to stabilisation of gas-saturated oil. Proposed method comprises two-stage separation at 20-80C with separation of gas at 1st separation stage at 0.11-0.16 MPa. It comprises also separation of degassed oil at 2nd separation stage at 0.01-0.06 MPa to obtain separated oil and gas. Separated gas is sucked off by degassing device, for example, ejector operated on associated gas from oil field separation stage. Here, extracted gas is mixed with 1st separation stage gas. Produced gas mix is cut in stable condensate and dry gas. Then, stable condensate is mixed with separated oil to feed stabilised oil and dry gas to consuming equipment.EFFECT: higher yield of separator oil.3 ex, 1 tbl
