NEW DCO Technology Oil Separation

A proven way to gain more Corn oil from your ethanol production process

Demonstrated performance through years of testing in our protein systems, this technology encompasses a multi-stage fiber washing with thin stillage clarification. A series of washing and clarification steps provide additional opportunities for the corn oil to be separated from the fiber for collection by the plant’s existing oil recovery system. Centrate from the fiber washing is sent to a final separation step to partition free oil from residual solids, producing an evaporator feed high in oil and low in suspended solids.

Because the DCO Technology™ system uses a fraction of the MSC™ patented protein separation technology, it is substantially less expensive. DCO Technology is housed within a new process building, constructed independent of the existing plant. This new building can be easily expanded to house the full MSC system when needed. A smaller footprint and streamlined equipment process means a relatively short construction timeline; as a result, biofuels facilities can quickly take advantage of rising oil values.

DCO Technology has many stand-alone benefits today, and can be a significant step toward the MSC protein system tomorrow.

DCO Technology utilizes multiple washing and separation systems to liberate additional distillers corn oil typically left on the fiber fraction in the DDGS. DCO Technology was born from FQT’s patented MSC protein separation system and is integral to the high corn oil yields obtained with MSC systems.

For Producers

CST™ Clean Sugar Technology – HIGH QUALITY, LOWER Carbon Intensity than traditional sources
  • Produce a lower carbon intensive sugar stream
  • Bolt-on commercially proven technology for ethanol plants
  • Operating since 2016

Get an equivalent sugar quality to a corn wet mill process with a >40% carbon reduction. CST not only produces an industrial sugar stream, it also yields a high-value corn oil stream and can produce valuable animal feed products, including a high-purity protein. The renewable chemicals market is growing rapidly, requiring a significant carbohydrate source. Add this system to a current ethanol facility to provide a sugar slipstream to meet those needs and significantly diversify a plant’s revenue streams.

For Consumers

A Lower Carbon Solution

Lower carbon footprints throughout the process

Clean Sugar Technology allows a dry grind facility to take full advantage of all the starch that is brought into the plant. By stopping the fermentation process at a key point of the starch conversion process (prior to ethanol production) allows the plant to produce the exact same sugars that the biotechnical, industrial and food industries are using today – at a smaller carbon footprint and more value than traditional sugar processes. The remaining streams are processed through the MSC process to produce high value proteins.

Technology Innovations

Fluid Quip Technologies has commercialized multiple patented technologies focused on enhancing the base corn-to-ethanol dry grind process and producing novel high-value feed/food products.

SGT™ Selective Grind Technology

  • Up to 3.0% increase in ethanol yield
  • Up to 22% increase in oil yield
  • Currently utilized in >2 billion gallons of annual production, globally
  • FQT paddle screens utilize a proprietary back-flush screen cleaning system, which can reduce labor
  • SGT reduces dough balling from slurry to achieve better corn flour water mixing, resulting in improved enzymatic activity

Increase ethanol and oil yields

The SGT system is installed in the mash cook process to expose more starch conversion to ethanol and to shear open the germ, releasing more renewable corn oil. This system reduces starch in dried distillers grains, reducing dryer loading while also increasing DDGS ProFat levels, depending on plant conditions. This allows for more oil to be recovered while maintaining a DDGS protein specification.

FQT provides customized systems based on plant size and objectives. FQT systems utilize various screen and mill designs including 36”, 40”, and 52” grind mills, to achieve optimum grind performance.

FBP™ Fiber By-Pass System

  • Remove fiber pre-fermentation
  • Produce a cellulosic ethanol feedstock
  • Increase fermenter capacity
  • Up to 10% plant throughput gain
  • Reduce distillation energy

Increase capacity
Fiber By-Pass separates fiber pre-fermentation for up to a 10% increase in fermenter capacity, boosting plant throughput. It can produce a pure fiber that is an excellent feedstock for cellulosic ethanol or industrial applications. Fiber can be recombined with stillage to produce traditional DDGS or sold separately achieving a higher-protein DDGS.

BOS™ Brix Oil Separation

  • High quality, low FFA oil (5-7% FFA)
  • Recover front end and back end oil
  • Total oil yield >1.0 lb/Bu

Recover corn oil from liquefaction
The BOS system separates free corn oil from liquefaction prior to fermentation. Recovering corn oil on the front end with BOS lowers the free oil content in fermentation. This allows for more oil extraction through fermentation and back-end oil yields are still significant.

L/MT Ethanol Yields From Corn




  • ~ 430-460L/MT ethanol yields from corn
  • Short payback timeframe
  • Removes corn fiber before fermentation

Blend corn with sugarcane as an ethanol feedstock
Integrate various FQT technologies for additive results, including SGT milling, BOS corn oil recovery, and FBP fiber separation. The WFS Flex Plant™ version produces a corn-based slurry stream without fiber, providing high yields of ethanol and co-products, and can blend into the existing sugarcane mill to utilize existing fermentation, distillation and evaporation. A facility can operate at full production capacity year-round.

WFS Flex Plant: Patent Pending


As the standard FQT process removes corn fiber prior to fermentation, we have developed a solution that allows corn sugars to be fermented in exactly the same way as sugarcane sugars, optimizing the process on rainy days and days of low ATR.

We have adapted our process so that the sugarcane mill does not have to adapt. This will allow the plant to process 100% ethanol, which will significantly improve its profitability.

How it works

FQT technologies are additive, so they can be combined in varying orders and applications to get the exact milling/separation process your plant needs. This mix of standard yet customizable configurations reduces capital expenditures, eliminates frustrations, and won’t leave your investments stranded.

1. SGT™ Selective Grind Technology

FQT has SGT, a selective grinding patented system, in which the wet grinding is made in the liquefaction. This mill liberates more starch so it can be converted into sugars.

The plants that operate with this system achieve higher ethanol yields (from ~3 to 5%), higher oil yields, besides reducing the enzyme consumption. In South America the corn is harder, therefore the SGT yield in that region can bump the yields to ~7% more, which will be in a range of ~430 to 460 liters hydrous ethanol per ton of corn at 15% moisture.

2. FBP™ Fiber Bi-Pass System

FQT has developed the FBP to remove the corn fiber before fermentation. This way, the sugarcane mills can use the existing fermentation, distillation, and evaporation systems.

The corn fiber is sold for animal nutrition, similar to corn gluten meal.

3. BOS™ Brix Oil Separation

FQT has developed BOS for oil recuperation from liquefaction. This low FFA oil can be destined to animal nutrition or chemical uses. The total oil yield (front-end + back-end) on FQT process can exceed the ~18kg/ton.


The MSC system created by FQT to produce protein after fermentation. Is a 50% purity protein product and is negotiated as a protein of high value in the corn gluten and brewer’s yeast market.
