Which unit is responsible for treating wastewater in the refinery process?

The PWTC (Produced Water Treatment Complex) is specifically designed to handle and treat wastewater generated during refining processes. This unit plays a crucial role in the environmental management of the refinery by ensuring that contaminants are removed from the wastewater before it is released into the environment or reused within the facility.

The treatment process may include several stages such as oil-water separation, filtration, chemical treatment, and biological processes to effectively reduce the levels of pollutants to meet regulatory standards. Each of the other units mentioned—such as the Coker Unit, SCOT Unit, and DHT Unit—serves different purposes in refining operations, primarily focusing on crude oil conversion and product upgrading, rather than wastewater treatment. Thus, they do not address the specific needs related to managing and treating wastewater within the refinery.
