Abstract

The invention provides a treatment device and method for alkali-washed butter of MTO product gas. The device includes a C4 deep-processing fuel oil supply device, an alkali-washed butter supply device, a mixing device and an oil storage tank; the C4 deep-processed fuel oil supply device is used to supply C4 deep-processed fuel oil; Butter; the mixing device is respectively connected with the C4 deep-processed fuel oil supply device and the alkali-washed butter supply device, and is used to mix and dissolve the alkali-washed butter and C4 deep-processed fuel oil to obtain dissolved oil; the oil storage tank is connected with the mixing device for Store dissolved oil. The above-mentioned treatment device provided by the present invention uses the C4 deep-processed fuel oil provided by the C4 deep-processed fuel oil supply device as a solvent, which can effectively dissolve the alkali-washed butter after being mixed with the alkali-washed butter in the mixing device, and form the dissolved oil to be stored in the oil storage Can. Dissolved oil has high stability and good fluidity, making it convenient for delivery and processing.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a processing device and method for alkali-washed butter of MTO product gas. Background technique [0002] The methanol-to-olefins unit (MTO unit) and the olefin separation unit are the core units in the coal chemical industry, which play a key role in connecting the past and the future, and are the key units for the success of the coal-to-olefins project. The methanol raw material is converted into product gas (MTO product gas) including ethylene, propylene and mixed C4, C5 and other hydrocarbons through the MTO unit, and then enters the olefin separation unit for product separation. After the MTO product gas is compressed in the second stage of the product gas compressor, it will enter the water washing tower to wash off the entrained oxides, and then enter the alkali washing tower to wash off the carried acid gas with strong alkali. Water washing and alkali washing are th...
