EFB Briquette: 3.942MWe Biomass Gasification & 1.7MWe Biogas Power Plant, Raub, Malaysia (Raub Energy Ventures Sdn Bhd)

The first EFB briquette biomass gasification plant in the world in Raub, Malaysia

Empty Fruit Bunch (EFB) is processed and converted into briquette. This EFB briquette, a homogeneous product with a higher energy density, is converted to renewable energy fuel called Product Gas via  gasification process. Anaerobic digestion is used to treat biodegrable EFB effluent generated by fuel treatment plant. This process produces biogas, consisting of methane and carbon dioxide. Product gas and biogas are fed into gas engines to produce electricity for captive use and export to the local transmission grid. In this way, waste materials that would traditionally be disposed off, are now generating revenue and profit.

Project Design Highlights

  • Biogas generated via anaerobic digestion process
  • Biogas produces 1.7MWe via gas engine for plant captive 
  • Conversion of EFB briquette into product gas
  • Product gas generates 3.942MWe for export to utility grid via gas engine 

Technical Specifications

  • 2 units of Biomass Gasifier
  • 4 units of Gas Engine
  • Gasifier consumes  105 tonne/day to generate:

⊕ 9,990 Nm³/hr of Product Gas
⊕ 3.942 MWe power

The most versatile machine that is used to grind almost all types of biomass materials. The grinding takes place between the high speed swinging hammers and top / side liners. Once the particle size reduces to that of the perforated / bar type screen at the bottom. It will be discharged through the hopper. The fineness of the material can be controlled by changing the speed of rotor (hammer), content of serrations on liners, number of hammers and diameter of perforations on the screen.
