On May 18th, the conference on the industrial application of pentane as a new type of welding and cutting fuel was held at China Shipbuilding Corporation Guangzhou Shipbuilding International Co., Ltd.
This achievement is the first successful industrial application of pentane as a new type of welding and cutting fuel in China.
"Pentane" usually refers to n-pentane, the chemical formula C5H12, the fifth member of the alkane group.
It is understood that pentane has the characteristics of high combustion calorific value. After full combustion, it is safer and more environmentally friendly than conventional natural gas and other welding and cutting fuels. It is an ideal substitute for conventional fuels.
Its high calorific value can also perfectly solve the cutting problems of medium and thick ship plates and special steel plates in the shipbuilding industry.
Guangzhou Shipyard International and Shenghuo Energy Technology (Guangdong) Co., Ltd. jointly developed a mobile blended light oil gasification system in three years, which solved the stable gasification technology of liquid pentane welding and cutting fluid under normal temperature and pressure and the pipeline transportation of gasification equipment. , pressure allocation and other technical problems, the pentane welding and cutting fluid can be supplied in cans, and the pentane welding and cutting fluid supply point can also be established. Through the gasification system, it provides a new green for the industrial application of shipbuilding enterprises. fuel choice.
It is reported that after the application and third-party testing agency testing, the use of pentane welding and cutting fluid has obvious gas saving effect, and the consumption of fuel and oxygen is reduced by more than 30%; the cutting efficiency is similar to or slightly higher than that of existing natural gas; Natural gas has obvious advantages in reducing slag and preventing edge melting in medium and thick ship plate cutting.
