Question
Question 1 The German-based company has a project aimed at developing viable concepts for the storage of excess electrical energy from wind and solar power plants. The project concept is the conversion of CO2-containing gases into methane in a pressurized reactor using hydrogen produced via electrolysis. The produced gas can be upgraded to synthetic natural gas (SNG) and fed into the well-developed natural gas grid. It can be seen that methane formation from carbon dioxide and hydrogen (methanation) is favored up to a maximum temperature of about 600°C. Carbon monoxide formation from carbon dioxide, on the other hand, is favored at temperatures above 600°C and 2,500 kPa. The synthetic natural gas (SNG) formed from the main reactor has the following composition: Synthethic Natural Gas (SNG) Percent Weight Composition (%w)- Dry Basis CH4 65.00% 02 7.40 CO2 27.60 Estimate the viscosity of synthetic natural gas from the pressurized reactor using: B. Empirical relations equation for mixture of gases
