Crude oil desalting operations produce an effluent stream which is challenging to treat due to its salt, heavy metal and hydrocarbon content. Consequently, desalter effluent (DE) is usually diluted into other effluent streams and sent to conventional wastewater treatment plants which may lead to upsets the plant operation.
In this study, a novel microbial approach was applied which investigated DE treatment using halotolerant yeast Debaryomyces hansenii (LAF-3 10 U) or the environmentally robust micro-algae Parachlorella kessleri strain CPCC 266. The effect of these two different approaches on both synthetic and actual DE was investigated in both batch and/or continuous mode. …

In the petroleum industry, Fluid CokerTM are used to upgrade the heaviest remains of heavy oil into useful lighter products such as fuel oil or petrochemical feed. The development of a better injection into a Fluid CokerTM is a key parameter to obtain a more efficient and sustainable use of heavy crude oil. The main detrimental factor in Fluid CokingTM is the formation of agglomerates between the injected oil and the coke particles. These agglomerates not only trap injected oil, not allowing free reaction, but also cause harm to the CokerTM when they fall to the …
