Mining

Hofstetter - Coal Mine Gas Flare

The HOFGAS-CFM4c high-temperature flare provides safe and environmentally friendly combustion of coal mine gas (Goaf-and Coleseam gas). HOFGAS-CFM4c flare is able to burn methane concentration from 20 vol.% up to 95 vol.% For each specific project the HOFGAS-CFM4c gas flare is designed for the specific customer requirements and coal mine gas composition

Hofstetter - Coal Mine Degasification System

Customised solutions for safe degasification of coal mines with reliable processing of the methane gas for electricity or heat generation. HOFGAS-CPM is comprised of one or several blower stations and the necessary components for faultless degassing. Defined control and regulation concepts guarantee safe and efficient operation.

Landfill

Hofstetter - High-Temperature Landfill Gas Flare

The HOFGAS-Efficiency high-temperature gas flare provides safe and environmentally friendly high-temperature combustion of landfill gas. The exhaust gas emissions meet stringent requirements.

Hofstetter - Complete Extraction and Gas Flaring System

The HOFGAS-Ready is a complete extraction and gas flaring system for a the safe and economical degassing of landfills. The gas is continuously collected and prepared for further use. The installation can be equipped with a gas utilisation connection for energy recovery. A complete degassing unit is built in a ventilated container, which makes the HOFGAS-Ready C plant theft-proof and protected against environmental influences. Controlled high-temperature combustion with concealed flame is guaranteed by the HOFGAS-Efficiency high-temperature flare.

Hofstetter - Gas Flare for Low Calorific Gas

An optimum solution for safe and efficient degassing of old landfill sites. The innovative HOFGAS lowcal high temperature flare for low calorific gas is designed to provide greater gas control during the latter phases of a site. Low calorific gas high-temperature combustion is necessary on more and more sites due to increased aftercare requirements. Falling gas volumes and lower gas concentration require innovative solutions. With HOFGAS-Lowcal, the existing gas collection system can continue to be used. Innovative, safe and efficient.

Biogas

Hofstetter - Standard Gas Flare for Gasholder Operation

Standard biogas / WWTP gas flare biogas plants. Ideal in combination with gasholder operation and gas systems with constant pressure ratios. Thanks to concealed combustion, the HOFGAS-IFL1c flare attains more than 99% combustion efficiency. The captivating aspect of the biogas flare is its straightforward design, combined with the latest safety technology.

Hofstetter - Biogas Flaring System

A customised HOFGAS-IFL4c biogas gas flaring system is deployed to comply with the stringent gas emission regulations. The system is simple to operate and adjust, and starts reliably. The high-temperature flare for biogas comes with the latest safety technology.

Industrial Gas

Hofstetter - Industrial Flare for All Combustible Gases

Customised industrial gas flare with high-temperature combustion, conceived specifically for the disposal of industrial and contaminated gases. Ideal for combustible industrial gases, such as VOC gas, pyrolysis gas, wood gas, flue gas, benzene gas and much more.

Technologies

Hofstetter - Siloxane removal Plant

Organic silicon-containing compounds, often referred to as siloxanes, are present in landfill gas and sewage gas. These components can damage gas engines, as silicon dioxide is formed in the combustion engine, which is highly abrasive.The Hofstetter Siloxane removal system reliably removes the siloxanes by adsorption to very low levels. Moreover, the system can be designed to remove both H2S and siloxanes.

Measuring / Monitoring

HOFGAS - Monitoring System

The Monitoring systems used by Hofstetter records plots signals, monitors limits, analyses measurement points, stores the data internally as well as on data medium. The automatic signal analysis provides a quick summary. Serial interfaces connect the Monitoring equipment with the PC or modem and enable communication with bus systems.
