DECONTAMINATION SPECIALIST

Chemical Decontamination

With PSC OZEST Life Guard™ decontamination programs, benzene and other hazards associated with refinery and petrochemical processing can be eliminated in a fraction of the time normally associated with a shutdown. PSC OZEST provides technical refinery expertise to enhance our turnkey service and to insure that every detail is properly addressed. The processes apply to crude units, FCCU units, lube oil plants, ethylene and butadiene plants as well. Our programs combine unique, environmentally safe chemical products with sate-of-the-art mobile pump and filtration systems. Furthermore, we can customize the service for various plant equipment including refinery distillation and fractionation towers, accumulators, drums, reactors and exchangers. It also safely removes Pyrophoric Iron Sulfides and residual H2S using second stage process that takes only 4 – 6 hours in most cases.

The Life guard chemical was developed and patented by PSC.

In general the client will determine what equipment within the unit is to be decontaminated. PSC OZEST will design a detailed procedure with regards to the most cost effective circulation loops. Upon approval of the detailed procedure PSC OZEST ties in the pump/filtration equipment and other accessories. A special formulated decontaminating solution is circulated for several hours at rates up to 2,000 gpm, filtering out solids down to 40 microns, if necessary.The emulsion that is formed is then broken down in a fracturing tank using a demulsifier to allow recovery of the hydrocarbon that is removed from the process equipment. The subsequent aqueous phase is discharged to the plant’s API or waste treatment facility. PSC OZEST closed loop system Life Guard™ makes EPA and OHSA compliance much easier to achieve.The major benefits are:

■ Zero LEL
■ Zero H2S
■ Less than 0.5 ppm Benzene
■ No steaming out or Nitrogen purging required
■ Less heat exchangers to be pulled during the shutdown, if included in the process.
■ Time saving.
■ Pyrophoric materials will be oxidized
■ Partial scales removal (when scale is bounded with hydrocarbon)
The Life Guard is
■ Neutral
■ Biodegradable
■ Has no impact on any material
■ Very powerful emulsifier
■ Can be easily Broken back into Oil & Water
■ More than 2000 projects worldwide including Saudi Arabia
■ Approved by CSDC ( Aramco ) & used in Ras Tanurah Ref, Riyadh Ref, Jeddah Ref, Yanbu Ref, Lub Ref, Sam Ref , Sas Ref, etc.
