Reduce benzene in waste water
This Midwest refinery was operating two separate sewer systems, only one of which was controlled per Benzene Waste Organic NESHAP (BWON) requirements. C&I handled complete engineering for the uncontrolled system, utilizing all disciplines to design and install two new flash drums with overhead condensers, overhead receivers, overhead oil pot, and related pumps and exchangers. In addition, the existing oily water sewer system for the petrochem area was converted to a controlled sewer system and connected to a new lift station via a new NESHAP Header, with two new feed tanks installed to collect the process waste streams.
C&I faced various logistical challenges, including restricted space for the installation and excavation that had to be shored up so that equipment was not negatively affected.
Coordination among departments and between C&I and the refinery was crucial to the success of this large project and was aided by 3D modeling, which helped with technical design.
