WATER TREATMENT CHEMICALS
Emulsion occurs at many stages in the production and treatment of crude oil. About two third of petroleum production of every oil field exists in the form of an emulsion. The emulsion stability results from the presence of interfacial barrier preventing coalescence of the dispersed water or oil droplets.
This is due to the presence of polar components such as asphaltenes, resins, wax and naphthenic acids in the crude oil. Therefore, before transporting or refining the oil, it is essential to separate the water for economic and operational reasons.
Minimizing the water level in the oil reduces pipeline corrosion and maximizes pipeline usage. The most effective method to overcome the problem is to demulsify the crude by using demulsifiers. The demulsifiers will destabilize the interfacial film between the droplets.
At the same time, it is important to reduce the oil content in produced water so that it can be discharged in the environment or reused. Thermax has a wide range of these separation additives. Screening of these products on fresh emulsion is needed to design the best suitable formulation and to optimise the dosage level for achieving the desired separation.
Mixture variety of surfactants to separate water in oil emulsions. Effective on a variety of oil emulsions with water cut ranging from 5 to 40%.
Deoilers / Reverse Demulsifiers :
In-house cationic polymers and modified polymers to treat oil in water emulsions. Suitable to meet environment norms for produced water.
