Several questions about the LNG industry

I have the same question. It seems like LNG is a new industry, and I also think it’s a bit unnecessary – it’s possible to transport gas directly through pipelines, haha

This post was last edited by lllllljjj on 2010-2-10 09:42. LNG is short for liquefied natural gas. Natural gas is liquefied under high pressure, and the temperature of the liquefied natural gas is very low (usually around minus 100 degrees). There are two main issues with all LNG: high pressure ； Low temperature. The so-called high-risk and unique industries refer to the two points mentioned above. Here are some reference materials you can take a look at: 1. FAQ on Liquefied Natural Gas technology http://bbs.hcbbs.com/redirect.php?fid=35&tid=158363&goto=nextnewset 2. Manual on key equipment and materials for Liquefied Natural Gas (LNG) receiving stations http://bbs.hcbbs.com/viewthread.php?tid=362244

The key equipment for LNG includes cryogenic tanks and refrigerant compressors, as well as storage tanks.

The liquefaction temperature of LNG at atmospheric pressure is 163 degrees.

1. Many people say that LNG is a high-risk industry. Is that true? Why? Do accidents happen often? Search on the forum for “Major events in the development of the LNG industry and accidents at onshore facilities”; these are some major accidents that have occurred abroad. Accidents in the LNG industry are not as frequent as those in other chemical industries. 2. What are the working conditions like in this industry? Is it higher than the oil refining industry? It’s hard to specify the industry standards – it’s like being in an oil refinery; how can Fushun Petrochemical be compared to Zhenhai or Guangdong Petrochemical? 3. What are the unique or key equipment for LNG? Can those who used to work in crude oil refining handle LNG? The uniqueness of LNG lies in the fact that it is a hydrocarbon gas liquefied at low temperatures; its hazards to humans include being toxic, harmful, flammable, and explosive, in addition to the risk of frostbite. Those who used to work in oil refining will face similar safety requirements when moving to LNG, and they definitely need to learn the operations again.

I have worked on several LNG gasification plants, and from a safety perspective, they are much safer than LPG plants. To date, no major LNG accidents have occurred in China, but there have been countless safety incidents involving LPG! ! Response to the question regarding the 2nd floor: Pipeline transportation of natural gas is the most common method in the natural gas industry. However, due to various factors such as gas field production levels and market conditions, pipeline transportation cannot deliver gas to every location. LNG, on the other hand, can be transported by ships, trucks, etc., allowing for flexible supply to areas where pipeline transportation is not feasible. Its high storage efficiency results in transportation costs that are much lower than those of CNG.

I would like to share my paper titled \"Potential Hazards of LNG and Their Preventive Measures\" with everyone, in the hope that it will be helpful to readers.

What makes LNG special is its low temperature; in addition, there are reports of natural gas being flammable and explosive, but it poses not such a high risk to operators – it is much safer compared to the petroleum refining and chemical industries, with minimal harm to human health. As for the benefits, they should be better than those in the oil refining industry. The key equipment is the storage tank, primary pump, high-pressure pump, and vaporizer.

People in this industry don’t receive any special treatment

The advantage of LNG is that it can be stored in large quantities in a small space, serving to balance supply and demand when there is an imbalance.
