Industrial gas is generally in the process of storage and operation, to strictly comply with the requirements, a little improper explosion may be, the following four causes of the explosion to tell.

The reaction got out of control and exploded

Most industrial gases under high pressure, oxidation, halogenation, polymerization and other exothermic reactions. When these reactions take place in the container, improper control of reaction conditions or failure of agitator, power failure, water stop, resulting in reaction heat accumulation, the temperature of the reaction system increases rapidly, so that the pressure in the reaction container increases sharply and the explosion occurs.

Gas industry

A gas leak caused an explosion

When the flammable gas is mixed with air to a certain concentration after leakage, it will explode under the action of ignition source. According to the explosion theory, the explosion of flammable gas in the air must meet the following conditions: First, the concentration of the mixture formed by flammable gas and air reaches the explosion limit, forming explosive mixture. Second, there is an ignition source capable of igniting explosive mixture.

Explosion caused by maintenance of production equipment

Industrial gas production equipment and equipment are complex, equipment and pipeline residual flammable, explosive, toxic and harmful, corrosive substances, maintenance operations are frequent and can not be separated from fire, a slight careless operation or violation of the operation process is easy to cause fire and explosion accidents. There are many reasons for equipment maintenance accidents, such as parking or test operation error, not according to the provisions of isolation and installation of blind plate, purging replacement is not complete, cleaning is not clean or improper, violation of maintenance operation rules, not according to the provisions of the fire analysis, etc..
