The sustainable alternative:
IMag S-ABSORB RAPID
Desulphurisation of biogas plants with iron hydroxide
The requirements for the desulphurisation of biogas processes are increasing. IMag S-Absorb RAPID, the sustainable iron hydroxide from IMagine, offers a solution. Our raw material is sustainable, made in Germany, REACH registered and undergoes continuous quality control. You are on the safe side with our iron hydroxide.
The sustainable solution for desulphurisation of biogas plants
Hydroxide IMag S-ABSORB RAPID is of natural origin
In Germany, streams, rivers and lakes are contaminated by iron-containing supply lines due to groundwater lowering as a result of mining. This has a massive negative effect on the ecology.
The polluted waters are extracted, cleaned and treated in a new process.
The aim is to clean the ecological systems with the downstream use of the active substances obtained in biological processes.
IMag S-ABSORB RAPID compared to previous processes
The iron products used in the European biogas industry are currently, as a rule, mined or produced in drinking water treatment through the use of iron chloride within the phosphate and heavy metal binding process.
IMag S-ABSORB RAPID makes the difference here:
Production process of IMag S-ABSORB RAPID
Until now, the raw material could not be used to manufacture a high-quality product.
The technical problem was solved in a two-year process development programme.
IMag S-ABSORB RAPID
Iron hydroxide – from ecological problem to product
IMag S-ABSORB RAPID is effective and sustainable
It is obtained synthetically and prepared, ground and homogenised using a wet-mechanical process. Due to the large surface area of the individual particles, IMag S-ABSORB Rapid is very reactive and produces a rapid desulphurisation effect. Thanks to its high purity, IMag S-ABSORB Rapid can be applied with the substrate as a fertiliser after the desulphurisation process. The material is REACH registered.
Iron hydroxide is often used in biogas production as an H2S absorber to remove hydrogen sulphide (H2S) from biogas. This process helps to improve the quality of the biogas, as H2S is undesirable and has corrosive effects. Iron hydroxide reacts with H2S to form iron(II) sulphide (FeS), which removes H2S from the biogas. This is an important step in the upgrading of biogas before it is utilised as a renewable energy source.
