Abstract
The invention discloses a method for reclaiming oil and gas in a tank car. Oil and gas overflowed when a volatile material is filled into the tank car can be effectively reclaimed by using a process of normal-pressure water absorption or negative pressure absorption produced by a water circulating vacuum pump and re-absorption of a water refrigeration unit so that the reclamation cost is relatively low, the operation is simple and the defect of high labor intensity due to frequent replacement of adsorbent in the conventional reclamation technology is overcome. When the volatile materials suchas capryl alcohol, industrial toluene, dimethyl benzene, gasoline and the like are filled by adopting the method, the reclamation rate of the organic materials can reach over 90 percent; and meanwhile, because the oil and the gas are not escaped in the filling field, the method avoids operation safety accidents of on-the-job employees, maintains the body health of the employees, realizes safe operation, reduces the production cost of enterprises and creates economic values for enterprises. The method is not only used for reclaiming the oil and the gas in the tank car, but also is suitable forcleaning the tank car.
Description
Technical field
The present invention relates to oil-gas recovery method in a kind of tank car, particularly during a kind of tank car can volatile material, the oil-gas recovery method in the tank car.
Background technology
Petrochemical complex supply and marketing enterprise and railway storage and transport unit when can gasoline in tank car and benzene class volatile organism material, adopt the oil filling riser injection mode.Because open wide roof manway, make the interior a large amount of oil gas of tank car excessive, not only cause the wasting of resources, also polluted environment.Simultaneously, also bring potential safety hazard and Occupational health injury to the operative employee.By retrieval, existing oil-gas recovery method exists the replacing sorbent material frequent, causes defectives such as the labour intensity change is big.Therefore, during can, invent a kind of method that oil gas is rationally reclaimed, petrochemical complex supply and marketing enterprise and railway storage and transport unit are seemed very important.
Summary of the invention
The invention provides the recovery method of oil gas in a kind of tank car, excessive oil gas when utilizing normal pressure or negative pressure state water to absorb can the can of efficient recovery tank car volatile class material; Not only can also protect environment, safeguard the healthy of employee for enterprise saves certain production cost, realize safety operation simultaneously.
Technical scheme of the present invention is: oil-gas recovery method in a kind of tank car, and its concrete steps are:
After A, tank car and the track contraposition, opened the roof manway lid of tank car by the operative employee; Then, computer control system is controlled special-purpose manhole casing and is covered described tank car manhole automatically; Described special-purpose manhole casing be fixed on the metal oil filling riser with hard tube that metallic hose is connected on; The soft foam pad of plastic cement is installed between described special-purpose manhole casing and the tank car roof manway;
B, described metal oil filling riser stretch at the bottom of the described tank car jar, the volatile class material of can; Work as when filling with substance, the organic materials gas of volatilization naturally in the described tank car through described metallic hose, enters in first heat exchanger package, is recycled stagnant liquid in the water that enters after the water cooling to 30 ℃～20 ℃ in the tourie;
Remaining air and a small amount of oil gas in the C, described tourie after second heat exchanger package is cooled to 10 ℃, cools off absorption agent in the tourie through two-stage again and stagnate and directly enter in the atmosphere after liquid is cooled to 5 ℃; Described second heat exchanger package and two-stage are cooled off the required low-temperature receiver of tourie again and are supplied with by the water refrigerating machine group;
D, cool off again total liquid in the tourie when described tourie and two-stage and run up to 50%～70% of tank volume separately respectively, and the proportion of supernatant liquid organic materials is 0.5～0.95 o'clock, computer control system commander pump start is recycled to the fluid organic material material automatically and waits in the storage tank to transport outward; Perhaps, the water that described tourie and two-stage are cooled off in the tourie again builds up to 30%～45% of tank volume separately through long-time the use, and the proportion of water is 0.98～1.0 o'clock, computer control system commander water pump cools off waste water in the tourie with described tourie and two-stage again and transports to and specify the industrial sewage pipeline.
Preferred embodiment of the present invention is: oil-gas recovery method in a kind of tank car, and its concrete steps are:
After A, tank car and the track contraposition, opened the roof manway lid of tank car by the operative employee; Then, computer control system is controlled special-purpose manhole casing and is covered described tank car manhole automatically; Described special-purpose manhole casing be fixed on the metal oil filling riser with hard tube that metallic hose is connected on; The ventilative gauze pad of stainless steel is installed between described special-purpose manhole casing and the roof manway;
B, described metal oil filling riser stretch at the bottom of the described tank car jar, the volatile class material of can; Work as when filling with substance, the organic materials gas of volatilization naturally in the described tank car through described metallic hose, is inhaled in first heat exchanger package, is recycled water cooling to 30 ℃～20 ℃, sucks stagnant liquid in the water in the tourie by water cycle vacuum pump group;
Remaining air and a small amount of oil gas in the C, described tourie after second heat exchanger package is cooled to 10 ℃, cools off absorption agent in the tourie through two-stage again and stagnate and directly enter in the atmosphere after liquid is cooled to 5 ℃; Described second heat exchanger package and two-stage are cooled off the required low-temperature receiver of tourie again and are supplied with by the water refrigerating machine group;
D, cool off again total liquid in the tourie when described tourie and two-stage and run up to 50%～70% of tank volume separately respectively, and the proportion of supernatant liquid organic materials is 0.5～0.95 o'clock, computer control system commander pump start is recycled to the fluid organic material material automatically and waits in the storage tank to transport outward; Perhaps, the water that described tourie and two-stage are cooled off in the tourie again builds up to 30%～45% of tank volume separately through long-time the use, and the proportion of water is 0.98～1.0 o'clock, computer control system commander water pump cools off waste water in the tourie with described tourie and two-stage again and transports to and specify the industrial sewage pipeline.
The present invention produces negative pressure absorption, water refrigerating machine group absorption technique again because using water at atmospheric pressure absorption or water cycle vacuum pump, make cost recovery cheap relatively, simple to operate, and it is frequent to have overcome existing recovery technology replacing sorbent material, causes labour intensity to become big defective.When adopting volatile materials such as can octanol of the present invention, industrial toluene, dimethylbenzene and gasoline, the rate of recovery of organic materials can reach more than 90%, simultaneously because the can scene does not have oil gas to overflow, avoided the generation of on-job employee's operational safety accident, safeguarded that the employee's is healthy, realized safety operation, reduced enterprise's production cost, for enterprise has created economic worth.
The present invention not only is used in the recovery of oil gas in the tank car, and is applicable to the cleaning of tank car.
