Embodiment Construction

[0050]In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] see figure 1 , a gas separation device for pyrolysis gas in an embodiment, including a purification device (not shown in the figure) and a liquefaction separation device 100 .

[0052] The purification device is used to purify the pyrolysis gas. The volume content of effective components methane in pyrolysis gas is about 40%-45%, the volume content of hydrogen-rich gas is about 20%-25%, the volume content of C2-C5 is about 10%-14%, and it also contains a small amount of carbon monoxide and nitrogen. One or more impurities in inert gases such as carbon dioxide, trace organic sulfur, sulfur ...

Abstract

A gas separation device of pyrolysis gas comprises a purification device and a liquefied separation device. The purification device is used for purifying the pyrolysis gas. The liquefied separation device comprises a first heat exchanger, a first gas-liquid separator, a hydrocarbon mixing rectifying tower, a second heat exchanger, a dehydrogenation rectifying tower and a methane rectifying tower. The first gas-liquid separator outputs a first hydrocarbon mixing product. The hydrocarbon mixing rectifying tower outputs a second hydrocarbon mixing product. The first heat exchanger outputs hydrogen rich gas. The methane rectifying tower outputs an LNG product. The liquefied separation device further comprises a mixed refrigerant circulation refrigerating device and a nitrogen circulation refrigerating device so as to supply the cooling capacity. According to the gas separation device of the pyrolysis gas, the first gas-liquid separator is used for gas-liquid separation, and then, the hydrocarbon mixing product, hydrogen rich gas and the LNG product can be obtained through three times of rectifying and separation. The device is not complex, the connection relation is simple, the gas separation technology is simple, and operation is easy. The invention further provides a gas separation device of the pyrolysis gas through the device.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a gas separation device and a gas separation method for pyrolysis coal gas. Background technique [0002] The resource conditions of "rich coal, little gas, and lack of oil" determine that China's energy structure will be dominated by coal for a long time. Modern coal chemical industry is an important way to promote the clean and efficient transformation and utilization of coal. The scientific and technological innovation and technological development around coal chemical industry have very important social and economic significance. The quality-based utilization of coal led by pulverized coal pyrolysis technology is one of the important technical routes of the coal chemical industry. [0003] Coal separation and utilization refers to a process in which coal is pyrolyzed through medium and low temperature dry distillation, volatile components (coal tar, gas) are removed, an...
