Abstract

Conversion of coal to synthetic natural gas of high calorific value comprises gasification to synthesis gas of medium calorific value, and methanisation. The desulphurised synthesis gas is conveyed by pipeline over a distance of 30-490 km to >=1 methaniser situated near a user of the process heat. The synthesis gas is methanised at high temp. and separate streams of methan-rich gas and high-temp. heat distributed to consumers. The reaction heat can be used in industrial plants requiring process steam, for generation of electricity and/or in boiling water reactors. Full use can be made of the methanisation heat, which is only partially used when recycled to an adjacent coal gasification plant. Increase in energy available is 15-30% of the combustion energy of the natural gas. Fluctuations in demand can be balanced by using the storage capacity of the pipeline and by use of multiple methanisers.
