Wärtsilä methane number calculator

Home Marine Products and solutions Gas solutions Wärtsilä methane number calculator Wärtsilä Methane Number Calculator Wärtsilä Methane Number Calculator We have developed this tool for ship owners and operators to calculate the Methane Number of the fuel gas. The calculation result indicates whether or not the given gas quality is suitable for use in Wärtsilä dual-fuel engines. If the entered numbers exceed 100% mol, the amount of CH4 is automatically adjusted. Methane CH 4 mol % Ethane C 2 H 6 mol % Propane C 3 H 8 mol % Iso-butane (2-Methylpropane) i-C 4 H 10 mol % N-butane n-C 4 H 10 mol % Iso-pentane (2-Methylbutane) i-C 5 H 12 mol % N-pentane n-C 5 H 12 mol % Ethylene C 2 H 4 mol % Propylene C 3 H 6 mol % Neo-pentane (2,2-Dimethylpropane) neo-C 5 H 12 mol % Mix-hexane Mix C 6 H 14 mol % Mix-heptane Mix C 7 H 16 mol % N-Octane n-C 8 H 18 mol % Carbondioxide CO 2 mol % Carbonmonoxide CO mol % Hydrogen H 2 mol % Nitrogen N 2 mol % Hydrogen sulfide H 2 S mol % Total mol % Calculate Wärtsilä Methane number (WMN) Propane Knock Index (PKI) The specified gas is suitable for Wärtsilä Dual Fuel engine.
