Peter Cheong
- Principal, Proxima Cancorp Inc.
- Director & Founder of Petrozyme Asia Ltd. – currently actively bidding on all major petroleum sludge/contaminated soil remediation jobs in Asia & Middle East
- Chartered Accountant – PwC, E&W
- Assembled a team of scientists to provide a solution for NORM
- Role – project & cost management
اسلاید 5 :
Treatment Rationale
- Had to look out of the box for a more cost effective solution
- The risk of NORM comes from small particles of radioactive metals
- Treat the cause not the symptom
- Solution had to isolate the NORM and then manage along with other metals
اسلاید 6 :
Treatment Process
- An advanced four-stage integrated bio-physico-chemical process to treat NORM-contaminated oily sludge & soil from the petroleum industry
- Each of the stages in this process has been field proven
اسلاید 7 :
Stage 1 – Removal of hydrocarbons
- biological process for oily sludges
- physico-chemical process for hydrocarbon-contaminated soils
- bioreactors and mixers will provide added shielding from NORM for the operators
- water is an integral part of both these processes
اسلاید 8 :
Stage 1 – oily sludges
- subjected to bio-treatment in a slurry bioreactor using the patented “Petrozyme Process”
- microorganisms, a blend of proprietary nutrients and optimized air flow facilitate accelerated biodegradation of petroleum hydrocarbons
- result is a >90% TPH removal in 8 to 12 days.
اسلاید 9 :
Stage 1 – contaminated soils
- for low oil-contaminated soils (<8% TPH), “Remsep” is used
- patented 2-phase remediation & separation process
- hydrocarbons are separated using hydrophobic sorbents & mobilizing agents in mixers
- removal of >90% of TPH in treatment periods of 4 to 6 hours.
اسلاید 10 :
Stage 2 - Solubilization
- solubilization done in tanks
- process proven on uranium, radium, thorium & strontium
- proprietary list of reagents containing selected ligands are used to solubilize radioactive & inorganic elements
- challenge is to ensure no reaction among reagents
- treated sludge/soil is dewatered & solids are sent to a suitable landfill
