![]() A computer simulation of the refinery’s WWTP process was developed in ProMax. ![]() The project was executed using simulation software and computer aided design software in conjunction with a 3D laser scan of the existing facility. The now clean and de-gassed wastewater is then pumped to the existing atmospheric tanks, ready to be processed by the biological portion of the WWTP. The flash drum provides a means to sequester gases that may be entrained in the water during the stripping process. The natural gas and stripped VOCs are sent to the fuel gas system where they can be utilized in the process heaters. The packed column uses natural gas to strip the VOCs from the wastewater. The second phase was to install a new column and flash drum. The first phase of the project was to redesign piping to move the API Separator to the front of the process train, where it would be most effective. Jōb found that the facility layout and mode of operation did not promote full utilization of the API Separator (oil/water separation equipment). Jōb Industrial Services (Jōb) was contracted to evaluate the existing configuration of the facility and to design a solution to reduce air emissions to an amount significantly below their permitted limit. ![]() A client was having issues with volatile organic compound (VOCs) air emissions coming from the wastewater treatment plant (WWTP) within their refinery.
