Chemical Cleaning Process

Chemical cleaning processes use chemicals to dissolve or loosen scale, debris and organic materials from pipe and process equipment during the commissioning phase of new plant facilities and equipment. Specific processes will vary based on specific equipment, the commissioning process and operational use cases.

In general, chemical cleaning processes follow these steps:

  • A system flush is performed with a chemical cleaning solution that’s often circulated through the system by a pump
  • The concentration and temperature of the solution are closely monitored, and the speed of the fluid circulation is held within a tight range
  • Fluid solution is used in a three-stage cleaning process, with rinses in between: degreasing, acid cleaning (metal collection) and passivation
  • Degreasing — an alkaline wash of internal process equipment surfaces to remove organic materials and debris
  • Water rinse
  • Acid cleaning — removes ionic deposits from metal
  • Water rinse
  • Passivation — the cleaned metal is in a reactive state; to reduce corrosion, it must be coated with a protective layer, which is typically done by reacting the metal with an oxidizing agent

At ESI, we handle both pre- and post-operational chemical cleaning, and we use environmentally friendly, biodegradable materials.
