SG Turbo Blowers and Compressors

Providing high efficiency over a wide operating range

Howden SG Compressors have removed more than 13 million tonnes of sulphur from the atmosphere in the last 10 years.  The SG turbo compressors range are used to remove and recycle sulphur gases, preventing it reaching the air we breathe. This is achieved by removing sulphur from the acid gases via the claus process.

Our sulphur recovery technology caters for the full range of sulphur removal capacities that can be integrated parts of complex gas cleaning line-ups to provide a safe and reliable solution that is economically attractive and environmentally responsible.
