Filtration for biodiesel plants

The Durco Biodiesel Equipment division of Ascension Industries Inc has announced a new range of biodiesel dry washing and filtration systems. The company has developed these new biodiesel purification and clarification systems from a line of vegetable oil dry washing & filtration units.

The new range of biodiesel processing equipment uses a two-step magnesium silicate dry wash and filtration process to purify and clarify biodiesel into high quality product (capable of meeting or exceeding ASTM-D6571 requirements) from a wide range of biodiesel from prepared feedstocks of yellow grease, tallow, canola oil, palm oil, rapeseed oil, soybean oil and waste vegetable oil.

Durco says that the systems can reduce overall biodiesel production time and cost because they eliminate the need for an oil/water emulsion gravity settling stage or a drying stage. This also significantly reduces biodiesel plant start-up and operating costs by eliminating the capital and maintenance associated with the traditional washing equipment. They also do not produce water effluent waste streams, which are hazardous by-products of traditional biodiesel washing and drying techniques.
