Answer 2

Mahler AGS process gas membrane units can be employed in numerous processes. The application area can range from purification or recovery of waste gas streams to generation of a high quality product (e.g. hydrogen, methane, syngas, helium).

Package units including process gas compression, pre- and after-treatment can be realized. A typical membrane system includes a treatment unit with filter and a heater for performance adjustment of the separation process itself. Additional after-treatment units can consist of optional drying units, heat management systems or even high-purity PSA systems. Also units including high pressure process gas compressors can be provided.

A unique selling point of Mahler AGS systems is the possibility of tailor made control systems for adjustable part-load operation and the design and execution of the plant based on customer's specifications.
