Marathon Ashland Petroleum to Save $39,000 through Cleaning Changes
Marathon in Ashland, Minnesota, had been using a terpene-based cleaner and petroleum distillate for external cleaning of large equipment. The terpene solvent was suspected to be impairing the biological processes of the refinery's wastewater treatment plant. During testing, two aqueous cleaners were applied as a foam that adhered to vertical surfaces for several minutes -- enough time for the cleaner to work -- then rinsed off with hot water. The refinery staff using one of the foaming agents described the result as "requiring less chemical, less time and less water, while providing better results" compared to the terpene-based cleaner.
