Black powder contamination in the process water prevented the de-salter filtration to efficiently purify the water.
The Pentair Filter had been increased to 25 microns in order to get a 5-8 day cleaning schedule at a cost of $13,000.00 per element change-out and disposal. The Pentair unit was unable to protect the $800,000.00 MycelX VOC and Oil removal system, rendering it out of service.
Install 2 BPS Magnetic Separators between the desalter vessel and water tanks, prior to the Pentair Filter.
The Pentair filter was changed to a 5 Microns polishing filter.
Pentair Filter Change-outs have gone to 130 days, eliminating 65 change-outs annually.
The solids loading dropped to unexpected levels, allowing the MycelX unit to operate.
Total Annual Equipment Savings: $200,000
