Model Series: BD-300

Gas Absorption Trainer with DCS Control 

Function: The separation of gas mixtures and recovery of the components usually involves a regenerable absorbent. In the natural gas processing industry sulfur 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 from a distributed control system
