This editorial review of best available, off-the-shelf and commercially viable carbon emission conversion technologies is provided for solid fuel power plant, chemical and hydrocarbon processing engineers & project planning professionals in the small-to-medium mechanical contracting trades. This assembly of critiqued case studies of existing or approved under-construction facilities provides a practical overview of the range of options available for retrofitting conventional coal-fired, MSW and biomass-fired power plants with CO2-sequestering chemical manufacturing capabilities. Conventional code-approved and industry-standard modular and zero-emission stack gas processing refineries are described as well as their performance parameters to include economic analysis applied to make from captured carbon emissions a broad range of marketable feedstocks such as syngas, hydrogen, methane, methanol, ammonia and a variety of other valuable chemical products. The primary focus is on project cost analysis for both construction and refinery operations over the life of the upgraded power generation facilities and refineries to ensure that retrofitted stack-gas capture adds value to the power plant projects ' or refineries' bottom line while meeting strict emission requirements. A comprehensive directory of applicable scholarly works on the subject is also provided. The extensively revised & expanded version of this work will be available to the public under a different title not later than 23 May 2023.
