Biodiesel: Centrifuges Enable a Paradigm Shift

from Batch-to-Continuous Process Productivity

Executive Summary

• Demand for biodiesel as a viable petrochemical alternative is growing exponentially.

• Traditional “garage-style” production methods such as settling tanks, filters and similar methods are slow, expensive, and cannot meet growing demand.

• A new method for biodiesel production must speed up production without diminishing product quality, while remaining cost-effective.

• This new method must not require a large-scale redesign of current facilities and must easily “plug-in” to existing systems.

• A paradigm shift from a batch-process to a continuous-process philosophy will maximize business profitability.

Industrial centrifuges are the clear answer, and deliver measurable financial and operational

results.

Common Production Issues

1. Biodiesel production can be slow

2. Biodiesel production can be process-intensive

3. Biodiesel production can be inefficient

4. Biodiesel production can be costly

These problems can be seen objectively as factors of:

• Time vs. output

• Labor vs. output

• Space vs. output

• Operations cost vs. output

At the end of the day: Output effects your Profitability

Issue 1 of 4

1. Biodiesel production can be slow and costly – WHY? • Solids clarification:

– Floor space cost: Tanks dispersed over large area.• Tank-to-tank transfer of fluids takes time and space. • Settling tanks are time-consuming for decanting and cleaning.• Labor-cost and downtime during decanting, cleaning and maintenance.• Expensive filters create costly production downtime -- components must be

disposed of OR cleaned for even less efficient re-use later • Process chemicals wasted in reaction with solids - wastes input costs.

– Light-Heavy Phase separation:• Solids suspended in both light and heavy-phase products reduce the quality and

resale value of end products.• Chemical / physical separation require heat and/or process chemicals.

– Lots of time and space needed for production flow from process to process.– Extensive latent time during actual production. – Large equipment expenditure.

3. Biodiesel production can be inefficient – WHY?• Batch production efficiency diminishes as the size of operation

increases. Efficiency per-unit volume goes down in large size production facilities.

– Batch tracking– Higher staff count– Product transit from space to space– Labor effort dispersed over a large area consumes time and effort– Settling tanks and filter systems occupy relatively large floor space

• Ability to grow (financially & volumetrically) is restrained by:– Current technology and – Limited floor space

Space vs. output factor…

Issue 4 of 4

4. Biodiesel production can costly – WHY?• The previous three issues all contribute ultimately to cost. • Additional factors not considered previously include:

– Cost of power to operate and maintain large facility– Cost to insure large facility– Environmental (fire, spills, etc.) risk of operating large

facility

All these issues effect your bottom-line productivity.

Where do Centrifuges Make the Difference?

• Pre-Production: Gross solids clarification

• Post-Mixing of catalyst (phase 1): Light/heavy liquids separation (including water separation)

• Post-mixing settling of catalyst and feed-stock (phase 2): Light/heavy liquids separation

• Phase 1 washing water separation

• Phase 2 washing water separation*

What else?

Particulate Separation In Mere Seconds

• Use US Centrifuge centrifuges to spin out particulate solids and water from crude bio-oil feed stock.

• Generally removes solids down to <5 microns.

• No need to replace or use filters.

• Also keeps you from having to scrape sludge out of mixing and storage tanks. Throughput = static settling speed X g-force X settling area

Translation:

“A centrifuge is nothing more than a large settling tank rolled into a compact package.”

Oil / Glycerin Separation In Mere Seconds

• Using alkaline-based catalysts currently accepted in biodiesel production, our stainless steel centrifuges separate the light (pure biodiesel) from the heavy (glycerin-based) compounds in seconds.

Features of US Centrifuge Equipment

• Automated particle sludge discharge (continuous operation) or manual-clean machines (interrupted operation).

• Oil stock is subjected to anywhere from 2000 to 18000 G forces for fast separation.

• Process anywhere from 250 - 1500 gallons / hr.

• 1-phase 120V AND 3-phase 220/480V available.

• Explosion proof design for safe use with controlled flammables.

Cost-effective solutions for both large & small operations.

Business & Operational Benefits

• Reduction in time vs. product output• Reduction in labor vs. product output• Reduction of floor space vs. product output• Redeployment of current floor space• Cost-effective• Labor reduction• Process-intensive systems reduced, simplified or eliminated • Plug-and-play• Accelerated return on investment• No point-of-failure in production system*

All these – PLUS...
