Production of LNG from coke oven gas
Thread Content
Hello, experts. Is it feasible to produce LNG by mixing coke oven gas with natural gas? What are the advantages and disadvantages? I would appreciate it if some expert could give me some advice. Thank you.
It is best to incorporate clean natural gas after it has been purified from coke oven gas, which can reduce the load on the purification process!
The purification of coke oven gas is well done, and the process route is feasible.
Coke oven gas can also be used to produce LNG; then why mix it with natural gas?
Components such as C2 and CO2 in coke oven gas have boiling points higher than that of methane; they must be purified, otherwise ice blockages will occur during the liquefaction of methane
With the existing mature technology, coking gas is first methanized to produce LNG, and many facilities across the country are engaged in this process. This needs to be determined based on the composition of your gas, mainly the ratio of carbon to hydrogen. The technology is mature; it depends on the conversion rate. You can send me the gas composition, and I’ll take a look for you
Feasible, process integration is required. Coke oven gas is purified and natural gas is also purified, followed by deep cryogenic refining.
Many companies are doing this; we carried out numerous dry quenching projects last year as well
