Biodiesel Production Technology Using Hydrodynamic Cavitation Reactor

BioGen Fuel Solutions has developed a proprietary production technique that provides a lower cost method ofproducing biodiesel, adds flexible feedstock capabilities and reduces the overall footprint of a commercialfacility. The proprietary process is based on the phenomena of hydrodynamic cavitation. Specifically, thetechnology centers on the design of an engineered orifice nozzle, or Vena contracta, based on incompressiblefluid dynamics, that will reliably produce hydrodynamic cavitation in large-scale production systems.

Each hydrodynamic cavitation chamber is a stainless steel assembly, with a 10 length and 3 diameter andwill process up to 20 gallons per minute (10 million gallons per year) of liquid. The standard hydrodynamiccavitation chamber is designed to safely operate at pressures in excess of 3,000 psi (lb per square inch),although our standard operating pressures are in the 1,000 psi range. The metal that is used to manufacturethe assembly is specially treated to reduce cavitation erosion of the chamber surfaces, which could occur atthese elevated operating pressures.

Hydrodynamic cavitation is the process of micro-bubble generation and implosion which occurs in a flowingliquid as a result of an increase and subsequent decrease in liquid pressure. Hydrodynamic cavitation can beproduced by passing a liquid through a constricted channel or orifice at a specific velocity. In our case, wehave designed a constricted channel with a unique geometry. When a liquid passes through the orifice, acombination of pressure and kinetic energy is produced that creates hydrodynamic cavitation downstream ofthe orifice, thus generating high energy cavitation bubbles.

The process of cavitation bubble formation and collapse results in very high energy densities, creating hightemperatures, intense shearing/mixing action and high pressures at the surface of the bubbles for a very short

time (microseconds). The overall liquid medium environment remains at ambient conditions, while at themicro level, the high energy phenomena occurs. This controlled cavitation can be used to enhance chemicalreactions, such as transesterification, which is the the chemical reaction responsible for the production ofbiodiesel.

Our hydrodynamic cavitation technology has the following advantages over conventional biodiesel processes:

Multi-Feedstock Capability

We can process a wide range of crude, refined and recycled feedstocks. This feedstock flexibilityreduces the overall feedstock cost, as we can utilize lower quality/lower cost materials.

Robust Cavtiation Chamber Design

There are no moving parts in the cavitation chamber, significantly reducing maintenance costs andincreasing process reliability.

Less Energy = Lower Processing Cost

Our process operates at a lower temperature than standard biodiesel processes, lowering overallenergy requirements.Less raw material (methanol) is lost due to evaporation during the lower process temperature, loweringoverall raw material cost.

Reduced Air Emissions

Lower process temperatures results in lower hazardous air pollutant emissions.Actual pollutant emissions will be below de minimus regulatory levels.

Because of the compact design of the process, a 10 million gallon per year biodiesel plant can easily beshipped in a single 40 foot long overseas container for final deployment in the field. The biodiesel process canbe coupled with a stand-alone generator, utilizing biodiesel as its fuel source, to provide the process electric

power.

Possible feedstock oils for the biodiesel process include:

Used Cooking Oil / Yellow Grease

Beef Tallow

Chicken Fat

Trap Grease

Soybean Oil

Algae

Corn Oil

Sunflower Oil

Canola Oil

Palm Oil

Jatropha Oil

Cotton Oil

Mustard Oil

Choice White Grease

Process Description

Biodiesel is produced with three principal feedstocks;

1. Feedstock Oil: Glycerides are commonly known as oils or fats, chemically speaking these are

long chain fatty acids joined by a glycerin backbone. They appear most often with three fattyacid chains connected to the glycerin, making them trigylcerides. In the US, the primary

triglycerides used for biodiesel production are soybean oil, waste vegetable oil (yellow grease)and animal fats.

2. Alcohol:Although a variety of alcohols can be used to produce biodiesel, such as, ethanol or

butanol, methanol is most frequently used. Therefore the biodiesel produced is referred to asmethyl esters. Methanol is one of the most common industrial alcohols. Because of its abundantsupply its most often the least expensive alcohol as well.

3. Catalyst: The third reactant needed is a catalyst that initiates the reaction and allows the

esters to detach. The strong base solutions typically used are sodium hydroxide (NaOH) andpotassium hydroxide (KOH).

The chemical reaction for the production of biodiesel is referred to as transesterification, and can bedescribed with the following equation:

CH2OOR1 CH2OH

catalyst

CHOOR2 + 3CH3OH ==> 3CH3OORx + CHOH

CH2OOR3 CH2OH

Vegetable oil + Methanol ==> Biodiesel + Glycerin

Our biodiesel system utilizes an advanced hydrodynamic cavitation design. Through this design, thetransesterification of feedstock oil occurs almost instantaneously, dramatically reducing the overall processing

time. High Free Fatty Acid (FFA) feedstocks, up to 10%, can be utilized with no pretreatment. We also havean alternative chemical process that makes it possible for us to convert trap grease (100% Free Fatty Acid)feedstock into biodiesel.

Each of the three chemical reactants are continuously metered into the hydrodynamic cavitation reactionchamber, which operates in the range of 1,000 PSI (pounds per square inch). The resultant product is amixture of biodiesel (methyl ester) glycerin excess methanol and catalyst The glycerin methanol and
