Case Study: Wastewater Treatment Plant Supplied In Tight Time-Frame Helps Louisiana Refiner Treat Increased Flow, Maintain Discharge Levels

Challenge

Calcasieu Refining, Lake Charles, La., needed to treat increased wastewater flow associated with major process expansions, while maintaining existing net load discharge levels.

In order to meet the timetable for the first process expansion, the equipment for the new plant needed to be designed and shipped to the job site within four-and-a-half months of the order award.

Solution

Siemens supplied oil/water separation, aeration and clarification equipment to the plant, and also was able to reuse some of the existing wastewater treatment equipment and tanks on site.

Siemens also identified other equipment and systems on site that could be used for temporary treatment while modifications to the existing system were made.

Results

The new wastewater treatment plant went on-line less than a year after Siemens supplied the plant's new equipment. The project was on-time, on-budget and is working well, and by reusing some of the existing equipment at the plant, the cost and area of the new wastewater treatment system was significantly reduced.

Says Toni Bennett, Technical/Safety/Environmental Superintendent at Calcasieu Refining, "Because we have numerous construction projects going on simultaneously at the site, we wanted a wastewater treatment company with significant experience in the petroleum industry that could provide all the major equipment, coordinate the design of the system and provide a complete mechanical and process guarantee. Siemens fit that bill."
