The Natural Gas and Hydrogen Mixing Skid (NGHMS) has the purpose to mix natural gas with high-pressure hydrogen and feed the produced fuel mix to a gas turbine.
The fuel flow to the gas turbine is controlled by the gas turbine. The NGHMS follows the gas turbine fuel consumption by keeping the fuel pressure constant.
The main purposes of the NGHMS are to reduce the hydrogen pressure to a suitable value for fine flow control and to mix hydrogen and natural gas to the desired volume ratio.
The system is designed to manage any blending ratio between CH4 and H2 depending upon the specific performances of the gas turbine. H2 range may vary from 0% up to maximum 90%. Consequently, CH4 serves to create the exact balance.
