Regarding solvent washing before the commissioning of petrochemical plants
Thread Content
I would like to ask everyone: is solvent washing required before the initial startup of petrochemical plants, and what are the requirements for such solvents? What kind of solvents are generally used?
Equipment that needs to be washed with a solvent likely has special requirements; generally, this is not done. For example, the special cleanliness requirements for fine chemicals and pharmaceutical equipment, etc
If solvent cleaning is necessary, it is essential to develop measures for occupational health protection, safety protection, as well as fire and explosion prevention, based on the physical and chemical properties of that solvent, and to prepare appropriate emergency response plans
