Heat and Power Production
Clean synthesis gas can be used directly for heat and power production in a boiler,
turbine, or engine, or recycled to supply heat to the syngas generator. In addition,
purge gas from the catalytic synthesis process can be used for energy or heat
production in the system. An advantage of the thermochemical approach to production
of alcohols is the ease with which any excess gas produced can be used for other
energy applications.
The gas cleanup requirements for heat and power production equipment are usually
less stringent than with catalytic synthesis. The level of gas cleanup required is
generally in the following order: boilers
