Zanni - Gas Stations

• To reduce the pressure an HP Reducing Station is required to reduce the gas pressure, for example, down to about 20 bar for the gas turbine applications.
• For most of the other applications, an HP Reducing Station is required as a first stage pressure reducing station followed by an LP station to reduce the gas pressure according to the requirements of the end-user, mostly down to less than 4 bar.
• A typical gas reducing station is consisting of emergency shut-off device (ESD), condensate knock-out drum, filter station, flow measuring, heater, line safety shut-off valve(s), pressure reducing valve, silencer, pressure relief valve(s), outlet section, instrumentation and control system.
• As auxiliaries it has condensate collecting  facility, N2-purging facility, flare and venting facilities.
• According to application, some of above facilities may not be needed.
• Filtering to clean the gas from impurities and liquid droplets is important generally but it is very important for industrial plants since they are using a huge amount of gas.
• Therefore, our gas systems include every time a reliable filtering system that guarantees a cleaning of impurities up to 99,5%.
• We have designed and installed several High Pressure and Low Pressure Reducing Stations according to International and German standards around the world.

* Gas systems are designed, manufactured and put into operation under control of engineers certified and authorized by DVGW by following the rules of the association strictly.

** The DVGW (German Technical and Scientific Association for Gas and Water) stands for the industry self-regulation in the gas and water supply industry.

Its technical rules are the basis for safety and reliability for German and European gas and water supply.
