Model Series: BD-300

Gas Absorption Trainer with DCS Control 

The separation of gas mixtures and recovery of the components usually involves a regenerable absorbent. In the natural gas processing industry sulphur compounds and CO2 are removed by absorption by an aqueous amine solution. In this trainer, an air / CO2 mixture emulates the raw gas stream and CO2, the acid gas. The amine is regenerated and recycled through the process. The trainer is equipped with industry-typical process measurement and control devices, providing a realistic training environment in which the students are exposed to many available technologies. The trainer is controlled by a distributed control system.

Process Highlights:
  • Continuously variable flows
  • Liquids are recycled
  • air and CO2 are vented outside
  • Intrinsically safe design
  • Designed for operations training
