The Minicombust is a catalytic oxidiser developed for a range of applications in both environmental remediation operations and industrial applications. This compact fully automatic catalytic oxidation system comes in two standard versions with rated capacities of 150 m³ / h and 500 m³ / h.

The Minicombusts are equipped with a dedicated control system to maximise productivity and safety. Constant monitoring of parameters, such as combustion chamber temperature, allows a high level of self-regulation via automatic dilution valves whilst an exceedance of user-defined operating limits, factory-set critical points or any type of failure will force a controlled plant shut down. All Minicombusts feature the very latest in true “fail-safe” technology.

Cooling and drying of the gas flow (stream).
This process is based on cooling the effluent to very low temperatures, using liquid nitrogen or other cryogenic fluid as the refrigerant. This allows the separation of the pollutants by reducing the vapour pressure in relation to the equilibrium between liquid / vapor and solid / vapor.

By implementing a condensation system it is possible to reduce the moisture loading and to potentially recover contaminants present in the gas streams from strippers, MPE and SVE systems.

The process is applied as a pre-treatment stage in the gas treatment phase to reduce excessive loading on the final treatment plant. In particular, the use of condensation as a pre-treatment for adsorption systems (activated carbon) increases the efficiency of the adsorbent matrix and reduces operational costs. Reduction of moisture in the gas flow and lowering of the gas temperature promotes maximum efficiency in the process of adsorption.

The application of condensation in the treatment of vapours is a particular specialism of Geostream.
