BIODIESEL Process Technology Bard Holdings

BIODIESEL Process Technology

There are three basic routes to biodiesel production from oil:
  • Base catalyzed trans-esterification of the oil.
  • Direct acid catalyzed trans-esterification of the oil.
  • Conversion of the oil to its fatty acids and then to biodiesel.

Most of the biodiesel produced today is done with the base catalyzed reaction for several reasons:

  • It is low temperature and pressure.
  • It yields high conversion (98%) with minimal side reactions and reaction time.
  • It is a direct conversion to biodiesel with no intermediate compounds.
  • No exotic materials of construction are needed.

The basic process is described below:

Algae Technology

Process / Production Plan

MAIN PRODUCTION PLATFORM - CULTIVATION: Initially six modules will be set up for the pilot facility. When we achieve full production each acre of floor space will contain approximately 1015 modules. The modules will receive the water, nutrients and carbon dioxide to commence the growth process at scheduled increments that would be staggered throughout the system.

HARVESTING: The harvesting of the algae is accomplished by a partial removal of the fluid contained in the clustered tubes. The remaining algae will multiply and refill the tubes when additional enriched water and carbon dioxide are introduced into the system. The algae, water and other products will be pumped to the processing area outlined above.

EXTRACTION: The algae will be extracted and the cells of algae will be exposed to ultrasound to free the oil content. The algae will then be separated by a centrifuge. The excess water will be re-circulated as will any excess carbon dioxide. The centrifuge will separate the algae oil and the algae residue, which becomes algae cake.

Key Benefits of BARDís Photo-bioreactor (PBRs)

  • It offers maximum efficiency in light utilization and therefore greatly improves productivity. Typically the culture density of algae produced in our PBRs is 10 to 20 times greater than bag.
  • Space saving. Can be mounted vertically.
  • Dramatically reduces labor requirements and eliminates handling problems.
  • Systems can be operated for long periods without culture crashes occurring.
  • Easy self-cleaning system can dramatically reduce fouling.
  • Closed, controlled, continuous automated systems and therefore cultures may be more easily kept hygienically. Environmental parameters are simply controlled.
  • Oxygen poisoning is eliminated, the system automatically releases all Oxygen.

Quality Assurance Plan

BARD is committed to producing the highest quality biodiesel; a critical aspect of achieving that goal is to be accredited under the BQ-9000 Quality Management Program. The accreditation process involves a formal review and audit of the capacity and commitment of the applicant to produce biodiesel that meets the ASTM D-6751 Specification for Biodiesel Fuel (B100) Blend Stock for Distillate Fuels. The accreditation process is comprehensive and includes a detailed review of the applicantís Quality System documentation, followed by a formal audit of the applicantís conformance to its System.

From the outset, BARD will be complying with BQ-9000 standards.
