Significantly Decreased Environmental Impact

Durco Filters Biodiesel Dry Washing & Filtration Systems supersede traditional water washing or bubble washing equipment to achieve highly efficient separation of the transesterified biodiesel process stream into clarified biodiesel (methyl-ester) end-product and recyclable by-product.

Durco Filters Biodiesel / Biofuel Dry Washing & Filtration Systems use a unique magnesium silicate dry wash process to achieve large-scale production of high quality biodiesel / biofuel, capable of meeting or exceeding ASTM-D6571 requirements. Pilot-scale testing facilities are available to validate product specifications for Your specific biodiesel / biofuel process in Your specific plant*.

Durco Filters Biodiesel Dry Washing & Filtration Systems reduce overall biodiesel / biofuel production time because they completely eliminate the need for an oil/water emulsion separation stage or a drying stage.

This also significantly reduces biodiesel / biofuel plant start-up and operating costs by completely eliminating the capital and maintenance associated with traditional washing equipment.

Additionally, these highly efficient and more environmentally friendly large-scale biodiesel processing systems have no water effluent waste streams, which are normally hazardous by-products of traditional biodiesel washing and drying techniques.

Durco Filters Biodiesel Dry Washing Procedure

The dry washing step employs a magnesium silicate mixing and adsorption process to quickly separate contaminants away from the purified biodiesel product:

Following transesterification, the unwashed biodiesel stream is sent to the mixing tank. Here a small amount of magnesium silicate adsorbant is intimately combined with the unpurified biodiesel to complete the "dry-washing" process.

After this short dry washing step, the process stream is then sent through a biodiesel filter that separates the purified biodiesel liquid from the solid dry wash adsorbant that is now loaded with impurities. The clean biodiesel product is now ready for storage and the solid by-product may be sold for a variety of uses including animal feed or fertilizer.

2 Proven Filtration Technologies For Large-Scale Biodiesel Plant

Durco Filters Biofuel Filtration Systems Are Specifically Designed & Engineered For Large-Scale (1,000,000 gal/yr PLUS) Biofuel Processing

Following the Dry Washing Step, a Filtration Step is required to remove contaminated adsorbent, and any other particulate as small as 1 micron. There are 2 highly proven filtration technologies, but only one of these will provide optimum performance in your specific process:

A wide range of suspended solids (typically 1-3%, by weight) may be removed, with the optimum choice of filter technology, depending on the specific size of your large-scale biodiesel production operation and several other critical process factors. Manual, Semi Automatic, or Fully Automated Operation. Optional fail-safe bag filter station available.

Dry Washing & Filtration For Biodiesel / Biofuel & Other Applications

Durco Filters Biodiesel Dry Washing And Filtration Systems are available as complete turnkey packages. Individual filter units can also be integrated into existing large scale biodiesel / biofuel production, or indeed any large-scale general silicate (ex. Magnesol or Trisyl Silica) filtering plant.

By choosing the optimum Durco Filters filtration technology, any dry washing or other particulate filtering system can be configured to handle a wide range of flow rates from virtually any industrial process stream. Batch or continuous production operations can both be supported.

Consult a Durco Filters Biofuel Filtration Engineer to arrange testing and analysis of your biodiesel / biofuel process stream and to determine the optimum filtration technology for your particular operation:
