Problems solved by technology

[0005] The purpose of the present invention is to provide a high-grade alkyne deep desorption device and process in the process of acetylene concentration, aiming at the defects of complicated acetylene concentration equipment and high energy consumption in the prior art. The absorbent of natural gas cracking products is desorbed sequentially in the upper and lower sections of the tower body. By setting process parameters such as temperature and pressure in different tower body sections, crude acetylene and higher acetylene are separated, which significantly simplifies equipment and energy consumption costs and improves the desorption effect. it is good

The device is characterized by comprising a desorption tower; the desorption tower is separated into two parts in the height direction: the upper part is an upper-section desorption tower (101), the lower part is a lower-section desorption tower (102), and the bottom of the upper-section desorption tower (101) communicates with the top of the lower-section desorption tower (102); the upper-section desorption tower (101) is provided with a liquid inlet, a crude acetylene gas collecting port, a lower outlet and a top inlet, and the lower outlet is connected to the top inlet through a second circulating pump (5) and a second heater (4); and the lower-section desorption tower (102) is provided with an advanced alkyne gas collection port, a bottom outlet and a top inlet, the bottom outlet is connected to the top inlet through a first circulating pump (2) and a first heater (6), and meanwhile, the first circulating pump (2) is also connected with an absorbent recovery pool.

Description

technical field [0001] The present invention generally relates to the technical field of producing acetylene from natural gas, and in particular relates to a high-level alkyne deep desorption device and process in the process of acetylene concentration. Background technique [0002] In addition to 8% acetylene by volume fraction, natural gas cracking products also contain a large amount of synthesis gas and a small amount of carbon black, methane, ethylene, methyl acetylene (M-C 3 h 4 ), propadiene (P-C 3 h 4 ), vinyl acetylene (C 4 h 4 ) and diacetylene (C 4 h 2 ) and other substances, in which the carbon black content is reduced to 3mg / m3 in the cracking device through the electrostatic precipitator 3 Within, the separation of the remaining components in the cracked gas is carried out in the enrichment section. Based on the physical and chemical properties of acetylene, NMP (N-methylpyrrolidone) is used as a solvent in the enrichment unit to separate the mixture of...
