Nathan DeMartino, president of Dexter Biodiesel Solutions in Pearland, Texas, said his company recently sold its first BCC900 Cold Clear unit to Keystone BioFuels, a 20 MMgy facility in Shiremanestown, Pa., and said that it is the largest unit sold “anywhere in the world,” and the largest install to date.

The larger models consist of completely different housing and filter systems than the smaller counterparts. They filter 45 gallons per minute of biodiesel fuel and can process 120,000 gallons to 200,000 gallons before the filters need to be changed.

This shows blenders and other high-throughput producers that the unit can handle their loads, DeMartino told Biodiesel Magazine. “I’m really excited about blenders and the market that is there for this system,” he said. “This installation at a 20 MMgy per year plant demonstrates to blenders that these larger units can be used to lead to better cloud point, pour point, cold filter plugging point and oxidation stability.”

Keystone BioFuels will use the Cold Clear unit as a quality control measure to ensure that the biodiesel they produce is consistently below the ASTM cold soak standard for biodiesel, which will “help them achieve the coveted BQ9000 status,” DeMartino said.

Cognis launches new cold soak, oxidative stability tests

By Nicholas Zeman

Posted September 2, 2009
Biodiesel Magazine
 
The latest system for cold soak filtration testing has hit the market, part of a trend over recent months that’s seen several companies offering solutions for biodiesel producers to meet upcoming enforcement of new ASTM guidelines.

Cognis Corp. announced that it has developed two new analysis capabilities for the Quality Trait Analysis (QTA) System for Biodiesel. “While already providing results in two minutes for 14 properties of biodiesel, the addition of the oxidation stability and cold soak filtration tests to the QTA System enables biodiesel producers and buyers to quickly assess the quality of their product,” the company stated.

This helps to reduce inventory carrying costs incurred while waiting on the traditional method of analysis at the same time, improving the throughput of the production facility or distribution terminal. “We are seeing a lot of companies offer their cold soak tests because they see an opportunity to help producers meet new ASTM guidelines,” said Raj Mosali of Ohio’s Jatrodiesel.

He added that distillation columns are the best way to meet cold soak requirements and that Jatrodiesel has developed its own testing procedures, and will not be looking to external sources to meet its testing needs. Other opinions were that distillation is very expensive, is not a guaranteed safeguard against sterol fall-through and removes natural antioxidants from the fuel. “It's so expensive and you have to use an oxidative stability additive, so I see distillation as self-defeating,” said one producer.
 
The problem in the field, according to Mosali, occurs when biodiesel is not blended promptly after leaving a refinery and experiences low temperatures, even if they are above cloud point. “What happens is that the fuel is heated back up before blending and then sterols fall through,” he said. Then that material is blended into the diesel fuel and it can contribute to filter plugging.

Megan Nitz, lab director for Prairie Pride Inc., in Deerfield, Mo., said she needed to see repeatability in the test phases of new cold soak products, the sample size and the result range before selecting a cold soak testing platform to meet the needs of her company’s facility.

“The addition of oxidation stability and cold soak filtration to the slate of tests required on each batch of biodiesel significantly increased the analysis time, by as much as 3 days,” said Barbara Stefl, Cognis global business director. “With the screening capability of the QTA System for these tests, producers and buyers of biodiesel can have confidence in the quality of the product before the long method is complete.”

Since it 2006 launch, the QTA System has conducted over 150 million biodiesel tests for its customers, has participated quarterly in the ASTM Interlaboratory Crosscheck program and recently, has successfully completed an AOCS sponsored round robin of its base capabilities as per the ASTM D6708 requirements.

Posted July 29, 2009

Enabling large continuous flow operations to conform to new cold soak requirements in the ASTM standard is now possible as SCchroeder 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.

Biodiesel companies pioneer process to assist in meeting ASTM cold flow standards

7/7/2009

Dexter Biodiesel Solutions and Schroeder Biofuels have developed a new proprietary multi-stage separation technology designed specifically to ensure that biodiesel products conform to the revised ASTM standard for cold flow properties. The ColdClear system consists of a three-stage bank of housings using a combination of filtration and adsorption principles to capture compounds that could cause plugging or crystallization in biodiesel fluids.

ColdClear solves the cold soak filtration dilemma in B100 biodiesel and biodiesel blends in a single pass with less than a .001% yield loss. There are variable sizes ranging from 25GPM, 50GPM and 100GPM+.

Schroeder launches Cold Clear Filtration system

By Nicholas Zeman


 

Posted May 18, 2009

Every biodiesel producer and distributor must pass the ASTM cold soak filtration test after Oct.1, 2009. Because many biodiesel fuel samples have failed cold soak filtration since its introduction into the fuel quality parameters, Schroeder Industries of Leetsdale, Penn., began to research the problems and develop a solution.

Adjusting the Quality Spec Won’t Alleviate Post-Production Concerns

..."One producer cited the fact that certain products, such as Schroeder Biofuels’ recently marketed Cold Clear filter, can bring biodiesel that fails the cold-soak spec into compliance while improving cold weather operability at the same time. “After this process does its work, there is the same level of monos,” says the producer. “The filter system eliminates the problems associated with longer cold-soak time biodiesel without reducing monos, so I don’t see the problems as being related.”

Region sees beginning of widespread energy boom
by Kim Leonard
TRIBUNE-REVIEW
...On a smaller scale, a Leetsdale-based company last month launched a filtration system for biofuels blenders that's designed to prevent the common problem of surface crystallization, and meet new production standards.

"I've seen more places in the U.S. that have more biofuels companies," said Jonathan Dugan of Schroeder Biofuels, founded two years ago as part of the industrial filters maker Schroeder Industries, which dates to 1946.:  "There's a big undercurrent of it beginning to emerge."
