Regarding liquefied gas LPG/LNG
Thread Content
Dear experts, since I have no experience in the field of liquefied gas, I would like to ask you some questions. Please forgive me if they are too silly: Is the use of liquefied gas currently mature? What is the level of popularity? Where are the main technical challenges? If it is gas produced from biomass, is it possible to liquefy it? What are the challenges? Is there any technology to remove CO from biomass gas? Thank you so much
Biomass gas? Do you mean biogas? Theoretically, natural gas is also a biomass gas.
The technology is mature, but the promotion strategy is not clear； However, most of the natural gas imported by our country is LNG ； Biomass gases can also be liquefied ； Whether it is natural gas or biogas, the challenge lies in the production, storage, and handling at ultra-low temperatures. To remove CO from biogas, it’s no problem from the perspective of compression + condensation.
It’s not biogas, and strictly speaking, it’s not either a biomass gas. It just can’t be classified for now, so it is temporarily defined as biomass gas.
"...To remove CO from biogas, it seems fine from the perspective of compression + condensation. Do you mean that CO can be removed through compression + condensation? Are there any technologies available to remove CO under normal temperature and pressure? Our company has also considered feeding the produced gas into the gas network, but the slightly high CO content is a bottleneck.
The ammonia synthesis plant uses a technology involving the absorption of chemicals in solution. . . . . . . .
3% - 5% volume percentage.
If it’s not at normal temperature and pressure, then what are the temperature and pressure? Or where can I find information on that process? I’ll go and look for it myself
A process of absorption + analysis. . . . . . You can give Baidu a try and take a look
