Countless processes produce gases and exhaust gases. We offer gas technology solutions for all applications.
Uncontrolled emissions of combustible gases can harm the environment, create safety risks and violate applicable regulations. At the same time, many of these gases represent a valuable source of energy.
Hofstetter provides complete gas technology solutions for the safe collection, treatment, combustion and beneficial utilisation of combustible gases across a wide range of industries and applications.
Hydrogen sulphide is a by-product in biological processes and corrosive in the presence of water. When H₂S is combusted, acids can form which cause major engine corrosion. We reduce H₂S to levels that meet engine manufacturer specifications.
Organic silicon-containing compounds are present in landfill and sewage gas. Silicon dioxide formed during combustion is highly abrasive. The Hofstetter siloxane removal system reliably removes them by adsorption.
By cooling and condensing the moisture in the gas, temperature and moisture content are brought to the desired level. Air fin gas coolers or chiller systems are used depending on required conditions.
Gas particles are removed by robust filter units. Different technologies are offered depending on the gas quality, particles in the inlet gas and desired degree of filtration.
Our engineers combine gas analysis, cooling, filtration, H₂S and siloxane removal into a single skid or containerised system — matched to your gas composition and engine specifications. That means fewer suppliers, faster installation, and one point of accountability for the lifetime of the plant.
Every Hofstetter installation is supplied with integrated control hardware and software — from blower capacity and pressure regulation to fully automated combustion control and continuous data logging.
Our engineers design the flare, skid or treatment stack — including FMEA, HAZOP and full P&ID documentation.
Radial and Roots blowers with variable speed drives to minimise power consumption.
Granulated bed activated carbon (also KI-impregnated) for siloxane and H₂S removal.
Gravel, ceramic, dust and coalescing filters — matched to gas quality and particle load.
PLC (Siemens, ABB, Allen Bradley or Mitsubishi), blower and pressure control, fully automated combustion control, data monitoring and logging.
Our specialists are happy to discuss your project — from custom flare design to complete gas treatment installations.
