SH S-KAT

The SH S-KAT is a compact biological desulphurisation system designed for smaller biogas plants, pilot installations and lower gas flow applications where reliable hydrogen sulphide (H₂S) removal is still critical.

Using a simplified biological process, the system provides effective H₂S reduction in a smaller, cost-effective footprint, making it ideal for sites where space, budget or plant scale do not justify larger desulphurisation towers. Despite its compact design, the SH S-KAT maintains stable performance and supports consistent gas quality for downstream equipment such as CHP engines and upgrading systems.

The system is designed for ease of installation and operation, offering a practical and reliable solution for operators looking to protect assets and improve gas quality without the complexity of larger systems.

Allison Engineering supports the specification and integration of SH S-KAT systems as part of complete biogas process solutions tailored to smaller-scale applications.
