The purge stream from the methanol stripper is routed to the biological wastewater treatment system. Previously the purge stream was taken at an elevation mid-way up the side of the stripper. By relocating the purge line to the bottom of the stripper, less methanol was sent to wastewater treatment.
This project reduced 9,300 gallons of methanol previously sent to treatment.
