Our product

The core business of BTG Bioliquids is the delivery and deployment of our patented fast pyrolysis technology. We do not produce pyrolysis oil but instead focus on delivering to our clients the core components of a pyrolysis installation.

The coming years BTG Bioliquids will focus on decentral, self-supporting fast pyrolysis units on a 5 to 30 dry tonnes per hour scale as these fit in with the logistics of the biomass feedstock. These units are self-supporting in the sense that heat for drying of the biomass is available from the process and sufficient electric power to cover the plant's total demand can be generated using a steam turbine in most cases. External energy from (fossil) fuels is only required during start-up of the plant. Furthermore no chemicals need to be added to the biomass in our process. These plants will be constructed using the modular building approach.

This video is about how we built our biomass fast pyrolysis plant Empyro in just 8 days by using the modular building approach.

Our unique technology benefits

BTG-BTL’s has taken BTG's patented RCR (Rotating Cone Reactor) fast pyrolysis technology and engineered it into a commercial industrial installation. Our improved RCR design offers a number of substantial advantages over competing pyrolysis technologies, including:

  • Compact equipment design resulting in low CAPEX
  • Skid-mounted modules to ensure plant construction is on time and on budget
  • Excess process steam and electricity production resulting in low OPEX
  • High feedstock flexibility
  • Clean and stable oil

Due to the characteristics of the BTG-BTL process it achieves lower CAPEX and lower OPEX than competing pyrolysis technologies. This also means that a BTL pyrolysis production plant can already be economic at lower biomass availability (from 5 t/h).

Pyrolysis oil price

Pyrolysis oil price

Giving a general relation for the price of pyrolysis oil produced using our technology is not straightforward. In general the production costs of the pyrolysis oil will depend on the investment in the pyrolysis installation (CAPEX) and operational costs (OPEX). In this example a standard BTG-BTL 5 t/h pyrolysis installation is assumed to operate on clean pine wood, which gets delivered and is then sized down and dried on site. The pyrolysis oil output of this installation is close to 24.000 metric tons per year.

OPEX

The largest share of the production costs of pyrolysis oil is usually the price of the biomass that is used as feedstock. This graph shows the operational costs per gigajoule of pyrolysis oil produced as a function of the cost price of the biomass on a wet basis. It is based on conservative values of the other operational costs, including personnel, maintenance and utilities, and a depreciation period of 10 yearsThe reason for also indicating the influence of the moisture content is that, in case the moisture content of the biomass is lower than 55%, BTG-BTL pyrolysis plants produce excess steam and electricity which can be sold. Steam is valued at 8 [€/GJ]  and no green incentives or subsidies are included in this calculation.

 

CAPEX

The total installed costs (turn-key) of a standard 5 t/h BTG-BTL pyrolysis installation are in the range of 20-25 MEUR. This includes the storage and pretreatment of the biomass, the proprietary pyrolysis components and flue gas treatment and oil storage.
