Rigorous testing and engineering design work have culminated in the development of the 'Pelly Model A5' Biodiesel Processor, our commercial introduction model. The sections below describe the processor and its capabilities.

Capability

The base 'Pelly Model A5' Biodiesel Processor will process 500,000 to 1,000,000 gallons of vegetable oil annually depending on configuration. The 'Pelly Model A' Series Biodiesel Processors are sold and delivered complete with a tank farm and related components. The final percent yields of fuel and final production times will vary depending on the condition of vegetable oil or animal fat feedstock. Fresh oil will produce the highest yield with the shortest duration washing time. Low free fatty acid (FFA) waste restaurant fryer oils will work in this system, but final biodiesel yields diminish depending on the degraded condition and concentrations of FFAs suspended in oil. Our system is recommended for feedstock oils with less than 5% FFA concentrations in order to achieve a higher percentage of biodiesel yield and shorter duration times for production, washing and polishing of the fuel.
 
Description

The 'Pelly Model A5' Biodiesel Processor is similar in size to a "refrigerator" and is coupled to a complete tank farm that is included in the package. Additional descriptors of this biodiesel processor include:
* Skid mounted 'Pelly Model A5' Biodiesel Processor incorporating innovative patent pending features coupled to a preheating, dewatering and reaction vessel with built-in safety, convenience and service features,
*Fast, on-site setup of complete processor,
*A system that is easy and predictable to operate, and quick and inexpensive to clean and service,
*Hands-free microprocessor managed washing/polishing system that incorporates fine-water misting, air bubbling, drying and filtration to clean up biodiesel product or the option for a ‘waterless’ polishing system to speed up operation and avoid the need for required water discharge permits.
*A fully enclosed, sealed, and easy to operate base catalyst and alcohol mixing system,
*Alcohol can be pumped to processor from drum/tote or moved to processor via inert nitrogen gas under low pressure. Either option has built-in safety features designed to both improve safety and increase operator convenience.
 
Operation

The 'Pelly Model A' Biodiesel Processor is designed to work on either freshly expelled and degummed oils or used restaurant fryer grease with low free fatty acid FFA content (<5%). The time needed to perform transesterification is about 200 gallons per hour. The time required to water wash and polish the fuel is usually 2-4 days depending on the condition of oil feedstock.
1. Vegetable oil is heated with a thermostat-controlled electric heater or boiler overnight when electric utility rates are lowest. The following morning water is removed from the heated oil (important when using waste kitchen grease).
2 .Operator next mixes oil blend prior to taking a sample for titration testing. The titration determines the amount of base catalyst necessary for a proper transesterification in any particular batch of oil.
3. Oil is mixed using the processor. Transparent flexible plumbing lines aid in observing fluids and reaction progress. Measured amounts of base-catalyst beads or flakes are introduced into alcohol tank for mixing. The processor's skid-mounted Alcohol/Catalyst reaction vessel mixes the alcohol and base catalyst into solution prior to mixing this solution with the vegetable oil.
4. The step of blending the catalyst solution with the vegetable oil is the actual transesterification step. Transesterification causes the vegetable oil to separate into biodiesel and glycerin. The 'Pelly Model A' series of processors will transesterify vegetable oil into biodiesel at a rate of about 200 gallons per hour.
5. After transesterification the glycerin separation is completed and crude biodiesel is pumped through a series of tanks for final washing, drying and polishing. After the polishing stage the biodiesel is pumped through a filter before exiting 'Pelly Model A' processing system and conveyed to the operators day tank or delivery truck. Glycerin by-product is conveyed into drums or totes for shipping to secondary users.
 We include; setting up system, a comprehensive operator safety equipment kit, operator training, a quick on the fly operator tutorial, and training on setting up a low cost restaurant waste grease collection route. Purchase is backed by ongoing technical support and a 12 month limited warranty from date of delivery. Delivery shipping costs of system and our travel expenses are extra.
Olympia Green Fuels is currently in development of an industrial grade version called the 'Pelly Model A6'. This system is a similar design to the 'Model A5' but engineered to process over five million gallons of oil per year. The price range and release date for this system is yet to be determined, but it will prove to be an affordable method for intensive biodiesel production.
