2 HistoryPSI-WS7 has its origins 20 years ago in the Western Canadian Sedimentary Basin. This development was a new approach to dealing with the heavy paraffin waxes and asphaltenes present in those limestone, shale and sandstone formations. The product has now been refined and has built on those early successes with current activity in the Middle East, backed up with independent third party verification.
3 Services with PSI-WS7Equipment cleaningCrude tank cleaning
7 Common problems Paraffin and asphaltene wax formation Pipeline plugging or restrictionsCorrosion of pipeline, tanks and equipmentWax build up in pipeline or plant facilitiesScaling and emulsionsDifficulties in removing H2SExcessive pressure, reduced volumesLow productivityHigh maintenance costs
8 What is PSI-WS7? PSI-WS7 is a charge soap or an anionic surfactant It has an affinity for any positively charged carbon or stainless steel surface, where it is drawn to the steel it forms a protective barrier filmTypically, results can vary depending onproject but can be as short as 24 hours
9 Features of PSI-WS7 Single product – multi purpose surfactant Corrosion control and preventionParaffin/asphaltene control and prevention (incl. crystalline wax)Drag reducerCleans pipe lines, pumps, valves and equipmentCleans tanks and facilitiesChemical injection servicesWell stimulation and work overEmulsion control and breakingReduces maintenance down time
10 Benefits of using PSI-WS7 Single product corrosion and wax inhibitorSolution drops out into the water and is water solubleEnvironmentally friendly and safe to administerEffective for onshore/offshore operationsCost effective and in most cases can reduce overall costs of chemical program
11 Application considerations for PSI-WS7 Pipeline dimensionsProduct being transportedFlow ratesGas and oil analysisFacility sizeAvailability of injection points, pumpsServices available: power, water, workforce campBrief history of identified problemsSpecifications of equipment related to problem
12 Application benefits of PSI-WS7 No limiting or restricting flow during injection processPSI-WS7 works quickly giving improved performance of valves, instrumentation and plant efficiencyResults often seen in just 24 hours:sales tanks cleanedflare tanks cleanedprocess vessels and lines cleanedclean and clear separation of water
