Electricity power generation consumables costs

It is estimated that this would cost about 8,000 per capita in the United States for 300,000 megawatts of generating capacity to replace the coal consumed in the U.S. for electrical power generation. Post combustion scrubbing is a well known but largely unapplied technology. 

The annual cost of the conventional alternative is calculated by using specific cost data for heat generation based on fossil fuels and for electric power purchased from utilities. These data are compiled for the different applications discussed depending on power demand, consumer specification (industry, utility, private) etc. 

However, much of the world is becoming increasingly electrified and currently, in the United States, more than half of the electricity generated comes from coal. In the foreseeable future, coal will continue to be the dominant fuel used for electric power production. The low cost and abundance of coal is one of the primary reasons why consumers in the United States benefit from some of the lowest electricity rates of any free-market economy. 

The UCBSRP process is claimed to have significantly lower capital and operating costs than the combination of an ethanolamine absorber/stripper unit plus a Claus plant plus a SCOT tail gas unit. Most of the energy consumed by the process is connected with the recovery and fractionation of propane and heavier hydrocarbons. Approximately 92% of the electrical power usage and 89% of the cooling requirements are associated with hydrocarbon recovery and separation (Sciamanna et al., 1988). The heat generated by the sulfur furnace more than offsets the heat demand required by the desulfurization of the natural gas stream.
