Problems solved by technology

The common practice of enterprises for this non-condensable gas is to directly discharge it to the flare gas main pipe, and burn it through the torch to avoid environmental pollution. The main components of the non-condensable gas are ethane, ethylene, propane, isobutane, etc. Alkanes, ethylene, propane, and isobutane are all very good fuels. It is a pity to burn them directly, which not only causes a waste of resources, but also is not conducive to the improvement of the economic benefits of enterprises.

Embodiment Construction

[0015] Such as figure 1 The shown alkylation compressor non-condensable gas recycling system includes compressor non-condensable gas outlet 1, fuel buffer tank 2, waste acid incinerator inlet 3, torch light inlet 4, the compressor The non-condensable gas outlet 1 communicates with the air inlet of the fuel buffer tank 2 , and the waste acid incinerator inlet 3 and the torch light inlet 4 communicate with the fuel buffer tank 2 air outlet.

[0016] It also includes a flare gas main pipe inlet 5, the flare gas main pipe inlet 5 communicates with the air inlet of the fuel buffer tank 2 through a pressure control valve 6, and the fuel buffer tank 2 is connected with a pressure control valve for controlling the pressure. 6 open and close pressure sensors 61.

[0017] The air inlet 4 of the torch light is communicated with a supplementary gas tank 8 through a self-operated regulating valve 7 .

[0018] It also includes a non-condensable gas outlet 101 of the light removal tower an...

Abstract

The invention discloses a system for recycling uncondensed gases of an alkylation compressor. The system comprises a compressor uncondensed gas outlet, a fuel buffer tank, a waste acid combustion gas inlet and a torch alert lamp gas inlet, wherein the compressor uncondensed gas outlet is communicated with the gas inlet of the fuel buffer tank; the waste acid combustion gas inlet and the torch alert lamp gas inlet are communicated with the gas outlet of the fuel buffer tank. By adopting the system, uncondensed gases generated in the alkylation production process of sulfuric acid can be recycled, and compared with the conventional mode that the uncondensed gases are directly discharged to a main torch gas tube and are consumed through torch combustion, the system has the advantages that resource waste can be avoided, and the economic benefits of companies can be increased.

Description

technical field [0001] The invention belongs to the technical field of non-condensable gas recovery and utilization systems, and relates to a non-condensable gas recovery and utilization system of an alkylation compressor. Background technique [0002] Sulfuric acid alkylation uses isobutane and butene as raw materials and concentrated sulfuric acid (98%w) as a catalyst to produce industrial isooctane. The process includes raw material pretreatment, reaction compression, refining, product fractionation, etc. During the production process, non-condensable gas will be discharged in an organized manner, such as non-condensable gas from compressors. The common practice of enterprises for this non-condensable gas is to directly discharge it to the flare gas main pipe, and burn it through the torch to avoid environmental pollution. The main components of the non-condensable gas are ethane, ethylene, propane, isobutane, etc. Alkanes, ethylene, propane, and isobutane are all very g...
