Chloroethylene sphere tank
Thread Content
1. Is it necessary to design a water injection system for vinyl chloride spherical tanks? Are there any specifications regarding water injection? Section 7.4 of SH3136-2003 states that spherical storage tanks for propylene, propane, mixed C4, extracted C4, and liquefied petroleum gas shall be equipped with water filling facilities. 2. The water injection setting is primarily used in scenarios where vinyl chloride leaks need to be contained at the base of spherical tanks; how can such leaks be repaired within a chemical plant? Are there measures for maintenance under pressure? It is still necessary to park the vehicle in order to work on the vinyl chloride storage tank; after venting the vinyl chloride, maintenance can be carried out.
1. Safety Supervision Administration General Order No. 3 [2017] 121: Criteria for Identifying Major Production Safety Hazards in Chemical and Hazardous Chemicals Production and Operation Units (Trial). VI. Full-pressure liquefied hydrocarbon storage tanks do not have water injection measures in place in accordance with ** standards.
1. The design of safety facilities for storing liquid vinyl chloride should follow the requirements applicable to the storage of liquefied hydrocarbons. Storage tanks for liquid vinyl chloride shall be equipped with a water injection system in accordance with current regulations. 2. In the event of a leak in the vinyl chloride storage tank, pressure-containing plugging methods should be used first for repairs, after which the vinyl chloride inside the tank should be emptied for further repair work.
