Hitachi Zosen Inova BioMethan

Gas Upgrading and Flue Gas Treatment

Hitachi Zosen Inova BioMethan GmbH offers innovative, comprehensive solutions for energy recovery from waste, gases, and flue gases. We develop and manufacture:

  • Gas upgrading plants that treat and refine raw biogas to deliver biomethane of a quality equivalent to natural gas
  • Facilities for feeding biomethane into the existing natural gas infrastructure
  • Carbon capture plants for separating CO2 out of flue gas for use as product gas or in liquid form for use as a fertilizer in glasshouses
  • Biomethane filling stations constructed in compact container form producing fuel from sewage gases or waste gases from communal facilities such as purification plants

We have the right technology to suit any client requirement, from pressureless amine scrubbing – a highly efficient, heat-led gas upgrading process – to our high-performance, pressure-controlled technology using membrane-based gas permeation.
This enables us to choose the process best suited in terms of the desired performance, the operator, and the requirements of the market.
Both of these upgrading processes ensure minimal methane slip while delivering a high degree of purity.
