Schroeder increases throughput of ColdClear

Enabling large continuous flow operations to conform to new cold soak requirements in the ASTM standard is now possible as Schroeder Biofuels has increased the handling capacity of its purification system for biodiesel. "This technology really has no top end" as to what capacity it can handle, said Jonathan Dugan of Schroeder Biofuels.

In the past year ASTM published specifications for blended fuel-from B6 to B20-as well as pure biodiesel which means fuel terminals and distribution centers which perform blending operations also have to comply with ASTM specifications. The increased handling capacity of Shroeder's ColdClear product will allow them to purify blended fuel as well.

"Biodiesel can get blamed for a lot problems," Dugan said. "You can have some really sparkling bio, but if it gets mixed with some crappy diesel, then you have cold flow problems-there's no specification for [petrol] diesel."

Because terminals and fuel distribution often have much higher flow rates than producers, Schroeder said they recognized the need for a 15 gallon per minute unit and a 45 gallon per minute unit. "We had customers ask us about larger systems and we were able to piggy-back on our standard technology to deliver a larger cartridge for filtration," Dugan said.

ColdClear is said to be the first multistage treatment system for solving the cold soak dilemma in biodiesel and biodiesel blends, and reducing costs associated with post-production treatments. "We have a terminal in our area that spent $2.5 million on cold flow additives last year, with our purification system in place it is going to drastically reduce its costs, because ColdClear reduces the need for additives," Dugan said.
