ApplicationsWaste gas scrubbing, suitable for removal of e.g. SO2, H2S, CS2, COS.
Another important application for glycol diether based absorption liquids is the Solinox® process. The Solinox® process was developed by Linde AG with Genosorb® 1900 as absorption liquid.
In this process, Genosorb® 1900 absorbs large amounts of SO2 from flue gases. The product contains a proprietary stabilizer that protects Genosorb® against harmful effects of SO2 and SO3.
The sulfur dioxide resulting from the Solinox® process has a very high purity and can be converted to sulfuric acid or sold as food grade quality.
Several commercial units are operating globally. The following table shows data of a Solinox® plant based in Europe:
- Air flow: 225 000 m3/h
- SO2/SO3 inlet concentration: 20 000 mg/m3
- SO2 in cleaned gas: max. 200 mg/m3
- Sulfuric acid production: approx. 40 t/day
- Sulfur dioxide emissions are reduced by 99.9%
