Pentane foaming agent is extremely flammable. Its vapor and air can form an explosive mixture. It is very easy to burn and explode in case of open fire and high heat Strong reaction with oxidant and even combustion Liquid is lighter than water and insoluble in water. It can drift and spread to a distance with water and cause combustion in case of open fire In the fire scene, heated containers are in danger of explosion.
The new technology of hydrobenzene removal with pentane foaming agent is to remove impurity benzene from raw materials under mild conditions (temperature 130 ~ 150 ℃, pressure 0.3 ~ 0.5MPa) and nickel catalyst. This process is used in the production of blowing agent of Junyuan Petroleum Group. After the application of this technology, the benzene content in pentane blowing agent is reduced from 300mg / kg to 5mg / kg, which has good economic and social benefits.
