The revolutionary and versatile RYDALL VP Specialized Degreaser provides a comprehensive cleaning solution for refinery process vessel cleaning and degassing that will reduce downtime, labor and water usage.

The revolutionary and versatile RYDALL VP Specialty Degreaser provides a comprehensive cleaning solution for refinery process vessel cleaning and degassing that will reduce downtime, labor, and water usage.

RYDALL VP Specialty Degreaser is a pH neutral degreaser that can be applied in circulation or vapor phase applications. In vapor phase applications, it will remove oil, gas, lower explosive limit (LEL), hydrogen sulfide (H2S), and benzene (C6H6 ) with the added benefit of cleaning hydrocarbon deposits in a single application. RYDALL VP  is also effective as a wetting agent additive to alkali or acidic solutions for chemical cleaning. 

Additionally, your plant personnel or on-site contractor can safely use RYDALL VP  without the need to bring in specialized consultants or contractors. It is also biodegradable and provides a fast and effective formulation of surfactants that is powerful, yet safe for your personnel, equipment, and our environment.

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’s 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 RYDALL VP. 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 accumulates 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.

Circulation Cleaning and Degassing Information

The basic process for vessel and pipe cleaning and degassing involves an aqueous solution of RYDALL VP that is circulated at an elevated temperature through the specified equipment and associated piping. A procedure that utilizes RYDALL VP in a chemical circulation will remove the oil and sludge from all wetted surfaces and reduce benzene to less than 1 ppm, H2S to near zero, and LEL to near zero.

RYDALL VP cleaning and degassing technology is the fastest, safest, most cost-effective solution for a wide variety of applications. RYDALL VP allows our customers to significantly reduce downtime for degassing and cleaning vessels and piping allowing you to get the unit on-line faster. Apex Engineering Products Corporation can provide comprehensive project planning services prior to your turnaround that can include pre-planning meetings, on-site inspections, detailed application procedures, estimated water & chemical usage, and waste disposal recommendations.

The addition of chemicals to the saturated steam injection (meaning the vapor phase) enhances the steam to remove the unwanted contaminants in shorter time periods.
