为满足一定范围的二氧化碳(CO2)而设计的各种工厂的成本和性能 本文通过改变CO2捕获率来评估排放量。这些的基本情况 国家能源公司超临界(SC)煤粉装置(PC)设计 技术实验室(NETL)的报告“化石能源的成本和性能基线” 植物,卷1a:沥青煤(PC)和天然气到电力,修订版3“[1]和 NETL的通用电能(GEE)集成气化联合循环(IGCC)装置 报告,“化石能源工厂的成本和性能基线,第1b卷:沥青煤 (IGCC)到《电力》,修订版2年美元更新。[2]选择的SC PC工厂是 基于情况B12B,不同之处仅在于增加了允许 离开脱硫步骤的烟道气流的适当部分朝向 该烟囱减少了Cansolv工艺中捕获的CO2量。选定的IGCC 植物基于案例B5B,不同之处在于绕过(部分或全部)水 气体变换反应器,从而减少Selexol工艺中捕获的CO2量。这个 这些植物中潜在的CO2捕获技术的主要成分被保存 对整个过程进行最小的修改。SC PC案例包括最新的成本和 来自最近供应商报价的性能信息,而IGCC的性能和成本是 根据修订版2报告中使用的旧引用,进行标准调整 将成本更新到2011美元。

The cost and performance of various plants designed to meet a range of carbon dioxide (CO2) emissions are evaluated in this report by varying the CO2 capture rate. The base cases for these designs are the supercritical (SC) pulverized coal (PC) plant from the National Energy Technology Laboratory’s (NETL) report “Cost and Performance Baseline for Fossil Energy Plants, Volume 1a: Bituminous Coal (PC) and Natural Gas to Electricity, Revision 3” [1] and the General Electric Energy (GEE) integrated gasification combined cycle (IGCC) plant in NETL’s report, “Cost and Performance Baseline for Fossil Energy Plants, Volume 1b: Bituminous Coal (IGCC) to Electricity, Revision 2 – Year Dollar Update.” [2] The chosen SC PC plants were based on the Case B12B, differing only in the addition of a bypass flow path that allows for an appropriate portion of the flue gas stream exiting the desulfurization step to be directed towards the stack, which reduces the amount CO2 captured in the Cansolv process. The chosen IGCC plants were based on the Case B5B, differing by bypassing (either partially or entirely) the water gas shift reactors and thereby reducing the amount of CO2 captured in the Selexol process. The major components of the underlying CO2 capture technology in the plants were preserved with minimal modifications to the overall processes. The SC PC cases include up-to-date cost and performance information from recent vendor quotes whereas the IGCC performance and cost are based upon the older quotes used for the Revision 2 report, with standard adjustments made to update the costs to 2011 dollars.
