摘要

Novel schemes for generating power from fossil fuel with CO_2 capture are under development and from time to time new schemes are proposed. Development of this sort of technology is both costly and potentially risky. A tool to screen such novel proposals in order to assess their performance and viability on a consistent basis has been developed. The tool uses standardised basic data on costs for common components and performs simplified calculation of basic gas and steam cycles if detailed information is not available. The program also manages the input of the overall heat and mass balance to ensure that losses and auxiliary power consumption are treated on a consistent basis. Where detailed heat and mass balances are available from a simulation program the tool allows key results to be input. The viability of a proposed technology is assessed in two ways using standardised questions about the state of development of the process, the complexity of the flow scheme, the type of materials, severity of process conditions, safety and environmental aspects. Answering these questions relies to some extent on sound chemical and mechanical engineering judgment and the tool is thus intended for use by professionals experience in the power generation and heavy chemical process field. The program assesses the overall commercial performance on a multi-criteria scoring basis taking into account, CO_2 emissions, fuel consumption, capital and operating costs as well as the process complexity and severity, construction material and natural resource requirements, development requirements, safety and environmental impacts. Credit is given in the scoring for good performance whilst use of exotic materials, extreme process conditions, dangerous processes or toxic materials is penalised. The tool also makes an assessment of the likelihood of success on a comparative, (i.e not absolute) scale. This allows results to be plotted in a two dimensional way so that the competitive position of process can be visualised both in terms of likely commercial performance and risk. The tool has been calibrated with several conventional baseline processes both with and without capture. This provides a backdrop on which novel competitors for the next generation of CO_2 capturing power plant can be plotted. The tool is offered as a means of screening out novel processes which have little chance of commercial success and also helping those which are more competitive to understand their potential strengths and weaknesses from a commercial as well as a technical viewpoint.
