RYDALL VP is a biodegradable specialized cleaner/degreaser specifically designed for refinery process vessel cleaning and degassing.

This truly revolutionary product will reduce downtime, labor and water required for cleaning and degassing storage tanks and refinery process equipment.  RYDALL VP can be applied in circulation or Vapor Phase applications.  In vapor phase applications, RYDALL VP will remove oil, gas, LEL, H2S and benzene with the added benefit of cleaning up to 70% of the hydrocarbon deposits in a single application.

How Vapor Phase Cleaning Works

Initially, the saturated steam with the vapor phase RYDALL VP will condense on the hydrocarbon residue coating the walls of the vessel, and start to increase the temperature of the residue.  Once the residue is heated, the vapor phase RYDALL VP will penetrate the residue and condense on the metal surfaces of the vessel. The presence of the vapor phase RYDALL VP will cause the vessel metal surfaces to become water wet, and allows the hydrocarbon residues to be flushed more easily from the metal surface by the action of the steam condensate containing the chemical.  Vapors, gases and volatile components will be carried out through the venting of steam, usually to the low point drains and plant flare header.  The remaining hydrocarbon residues and sludge that accumulate in the bottom of the vessel will be emulsified by the steam condensate and vapor phase RYDALL VP that also runs down to the bottom.
