How to remove benzene from the raw material benzene tank…

It is a tank containing raw benzene, and work involving open flames is to be carried out on it; how should the benzene be handled? I seek advice from everyone
Reply to 1# Drunk￥Third Young Master: 1. First, drain all the benzene from the storage tank. 2. Close all the valves in the pipes connected to the benzene tank and install blind flanges on them. 3. Flush the tank with steam. 4. Conduct analysis tests to ensure everything is satisfactory. Be sure to check that there are no dead corners; if conditions permit, I will keep the steam flow at an appropriate level during the work to maintain a positive pressure in the tank and eliminate any oxygen.
Cook it with water at a boiling temperature of 100°C, which is higher than the boiling point of benzene; cook for an extended period of time, three to four days, and then test it with water again – it should meet the requirements. I’ve done this before
Benzene is toxic, as well as flammable and explosive; it must be thoroughly cleaned before use, without any doubt. There are various cleaning agents available for cleaning benzene, and you can choose the one that works best. Additionally, benzene has a boiling point of 80 degrees, so boiling it or using steam heating can also be effective ways to remove it.
