Eaton’s filter housing and filter bags improve biodiesel loading system for manufacturer

Supplier News

A solution provided by Eaton Filtration helped a biodiesel manufacturer eliminate the expensive but inefficient duplex cartridge filter in their biodiesel loading system.

With the alternative fuel market facing tighter quality standards, the biodiesel manufacturer had installed a vertical duplex cartridge unit to filter biodiesel from a storage tank into trucks and rail cars.

The purpose of the filter was to remove any storage tank related impurities from the product before transport to customers. The vertical cartridge vessels had bottom outlets, which raised the vessel opening to a height of over six feet.

There were several challenges in the handling, operation and servicing of the filter cartridges. The expensive jumbo cartridges used in the vessels were extremely heavy and difficult to remove, while the operators did not have a platform or any other method to position themselves for safe and easy removal of the dirty cartridges. Besides, several changes of cartridges were required to filter a single batch.

Key objectives for the customer in seeking a new filter system included lower costs, ease of operation, safe servicing and quality filtration. The ultimate goal was to filter a single batch of over 900,000 gallons of biodiesel without having to change filters.

After extensive testing with different types of Eaton filter bags, the customer concluded that the Eaton filter housings would improve filtration efficiency and reduce costs.

The old duplex cartridge filter was replaced with the QIC LOCK MAXLINE filter housing using Eaton’s DURAGAF Extended Life filter bags. The customer is now considering Eaton’s new HAYFLOW filter elements for even longer service life when they begin to process larger batches of biodiesel.
