Sinopec News Network reported on September 18 that the hydrogen-rich gas utilization unit of Sino-Korea Petrochemical's dry gas enrichment unit successfully entered the stage of production and transportation, and the hydrogen yield reached 66.
77%
.
The hydrogen-rich gas utilization project uses the difference in solubility and diffusion coefficient of different gases when passing through the membrane separator to achieve the separation of hydrogen.
The membrane separator is filled with hollow fiber membrane filament modules.
Permeate the fiber membrane filament at a faster rate to obtain hydrogen-rich product, which enters the cracked low gas PSA
.
In the past, only a very small part of the adsorbed waste gas produced in the dry gas enrichment unit entered the plant's No.
2 hydrogen production unit as a raw material, and the rest was burned as an ordinary fuel in the fuel gas pipeline network, resulting in a large waste of resources
.
After the hydrogen-rich gas utilization unit is put into use, the adsorption waste gas generated by the dry gas enrichment device is maximized, and the surplus production capacity of the cracked low-fraction gas PSA is rationally used, which creates certain economic benefits for the company
