Let’s talk about the development and current situation of coal-to-natural gas technology.
Thread Content
What is being built in China seems to be the Datang Keqi project and the Xinjiang Guanghui LNG project. What is the technological development level and prospects of coal-to-natural gas? Let’s discuss it:)
From the perspective of my country’s resources, the development of coal-to-natural gas is very necessary.； In terms of supply, demand and market, the gap for natural gas is still relatively large. ； In terms of clean energy, it is also necessary to prepare coal into natural gas. ； In terms of technological maturity, I think it is more reliable than coal-to-olefins. So I think it’s very promising.
Methane from coke oven gas is separated through a pressure swing adsorption unit and further processed into liquefied natural gas (LNG)
Our company is preparing to gasify coal for natural gas, and the technology should be relatively mature.
The coal-to-natural gas project technology is very mature, and Datang has already started placing orders for equipment.
The coal-to-natural gas technology is very simple. After gasification to formulate syngas, a methanation reaction is added to increase the methane content. The market prospects depend on regional resources, and overall it is not very hot yet.
Our country's resource structure is rich in coal, low in oil and low in gas, so for a long time, coal will be the main source of energy consumption. At present, the clean utilization of coal is a key and basic technology. Both coal gasification and liquefaction have great development prospects. The contradiction between my country's natural gas supply and demand is increasing day by day, and oil security is under pressure. Therefore, seeking technological solutions for replacing oil and coal with coal is not only necessary to maintain the sustainable development of energy and economy, but also to ensure my country's energy security.
It should be technically mature, and except for methanation technology which needs to be imported, other technologies are basically mastered domestically. The biggest constraints are coal price and water. Coal type and total quantity are also big constraints. Although the prospects are good, there are not enough financial resources to support and * * Can't support it
Coal-based SNG should have certain development prospects in the future. At present, transportation by other means besides pipeline transportation may be a problem.
I posted here about the current status and development of coal-to-natural gas technology and made a detailed analysis of the questions you raised. Please refer to it. I hope it will be helpful to you. http://bbs.hcbbs.com/thread-436178-1-2.html
