Conversion of coal-fired power plants to co-generate cement

Abstract

The invention provides systems, processes and methods for converting heterogeneous coal-fired power plants to cogenerate a sustainable, consistent, and economic cement. Such cogeneration enables a simultaneous production of both electric power and cement and thus provides significant economic and environmental efficiencies and benefits and eliminates a major source of greenhouse gas emissions and thereby mitigates a major contributor to climate change.

Description

[0001] This application is incorporated by reference in its entirety in US Provisional Application US60 / 914026, filed April 25, 2007. Background technique [0002] The burning of coal for electricity generation is a major contributor to global warming, producing billions of tons of CO every year 2 and other greenhouse gases, despite further developments in coal combustion and carbon capture technologies, GHG emissions are still expected to increase significantly. In 2003, coal accounted for 24 percent of the world's total energy consumption. World coal consumption and resulting GHG will almost double in the next 20 years, from 5.4 billion short tons in 2003 to 10.6 billion tons in 2030. The burning of coal for cement production is also a major contributor to global warming, generating more than 2 billion tons of CO in 2007 2 and other greenhouse gases, despite industry tolerances, total emissions are projected to increase substantially. For example, emissions from cement pr...
