Biodiesel Plant

Biodiesel Plant ‒ Clean Fuel from Grease

A biodiesel plant produces environmentally friendly, profitable biodiesel from vegetable and animal fats and waste oils. Biodiesel can be used blended with normal diesel as transport fuel, as heating oil or fuel for generators. The end-products of the production process are biodiesel and valuable glycerol for the chemical industry. 

Suitable feedstocks for biodiesel production include:

  • animal fats
  • oils from fish production
  • used cooking oils from restaurants 
  • waste oils and fats from the food industry
  • fat from grease traps and other low-grade fats mixed with water.

Biodiesel Plant Profitability

Biodiesel production cost is low and the demand for end-products high, hence the biodiesel project payback period is typically very short, usually only 2 to 4 years. The plants are factory-built, so they are quick to install and start up. The processing capacity for a profitable biodiesel project is at least 20 tons of feedstock per day. The capacity of the plant is fully scalable.

Advantages of the biodiesel technology offered:

  • Extensive raw material base
  • The end-product meets the requirements of ASTM D6751 and EN 14214 and has a very wide market as a blend with fossil diesel
  • Short payback period; typically 2-4 years
  • Suitable for decentralized biodiesel production
  • Easy-to-use, continuous, automated processes
  • Accurate technology solution based on the quality of the raw material
     

Biodiesel Hybrid Technology

Hybrid biodiesel plant combines traditional biodiesel production technology with a next generation patented supercritical process. Hybrid technology provides significant benefits when dealing with reasonably challenging feedstocks with a free fatty acid (FFA) content between 0 and 20 %. The hybrid process enables the separation and conversion of free fatty acids into biodiesel in a supercritical process, whereby only good quality fats are introduced into the conventional catalyst process.

Hybrid Technology Benefits: 

  • Possibility to handle challenging feedstocks with FFA up to 20 %
  • High total biodiesel yield
  • Very good quality of end products (biodiesel and glycerol)
  • Methanol consumption only 25% compared to acid esterification
  • Catalyst consumption 25% compared to conventional process
  • Lowest processing cost in the industry and thus excellent profitability.
     

Supercritical Biodiesel Process for Challenging Feedstocks

Supercritical biodiesel process is an excellent alternative when the content of free fatty acids (FFA) in a feedstock is higher than 20%. The process does not require acid or base catalyst. Chemical reaction occurs at high pressure / temperature, breaking the chemical bonds of the fatty acids and reacting with methanol. The end products are clean and require little post-treatment, making it an outstanding technology.

Supercritical Biodiesel Process Benefits

•    Handles feedstocks with FFA up to 100 %
•    When handling challenging feedstocks, the production costs are significantly lower compared to the traditional process
•    Excellent quality of end products 
•    No need for alkali or oxygen catalyst
•    No salts, no soaps and no side products formed during the process
•    Simple process, low maintenance costs.
