Embodiment Construction

[0007] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] The butane emission recovery system of the oil factory is realized by the following steps. The butane gas produced in the oil factory during the process of production refining, deep processing, and technological innovation passes through the collection device. The whole device opens the valve (2) from top to bottom, and the butane The gas enters through the air inlet (1) on the upper part of the device, the gas flows through the serpentine condenser (3) in the condensate container (7), cools down and liquefies, and the liquefied butane exits from the serpentine condenser (3) The liquid pipe (5) enters the butane collection device (6) at the bottom of the device and gathers. The condensate uses cold brine, which can reduce the time for gas liquefaction. The brine flows from the condensate inlet (8) into the condensate formi...

Abstract

The invention discloses a butane exhaust recovery system for an oil factory. Exhausted butane is recovered and utilized in a centralized manner. The system consists of coiled condensation pipe cooling equipment, a condensate container and a butane recovery device. The exhausted butane enters the system from a gas inlet, and is cooled to be liquefied by a coiled condensation pipe, liquefied butane flows into the butane recovery device from top to bottom along the condensation pipe, and the condensate consisting of salt and water can be recycled through a condensate recycling device to promote the liquefaction of butane. The butane exhaust recovery system is easy to operate, gas pollution is greatly reduced, and environmental pollution is also reduced; the system is simple, novel and unique in structure and convenient to operate, and economic benefits, social benefits and environmental protection benefits of the oil factory industry are improved.

Description

technical field [0001] The invention relates to the utilization and recovery of resources in enterprises and industries, is the recovery and utilization of polluted waste gas butane in industrial grease factories, and is a liquefaction device with simple operation. Background technique [0002] At present, the problem of exhaust pollution emission is a common problem, and it is also a subject that needs to be solved urgently. The butane exhaust gas produced in the production, refining and deep processing of oil factories is directly discharged into the atmosphere, which causes serious pollution to the environment and is also a waste of materials. . Butane is a raw material for organic synthesis, which can be used as solvent and refrigerant. Butane can also be used as a motor fuel blend to control volatile components; it can also be used as a deasphalting agent for heavy oil refining; a wax precipitant in oil wells; used for secondary Spilling agent for secondary oil recover...
