資料簡介

為滿足一定范圍的二氧化碳(CO2)而設(shè)計的各種工廠的成本和性能本文通過改變CO2捕獲率來評估排放量。這些的基本情況國家能源公司超臨界（SC）煤粉裝置（PC）設(shè)計技術(shù)實驗室（NETL）的報告“化石能源的成本和性能基線” 植物，卷1a：瀝青煤（PC）和天然氣到電力，修訂版3“[1]和 NETL的通用電能（GEE）集成氣化聯(lián)合循環(huán)（IGCC）裝置報告，“化石能源工廠的成本和性能基線，第1b卷：瀝青煤（IGCC）到《電力》，修訂版2年美元更新。[2]選擇的SC PC工廠是基于情況B12B，不同之處僅在于增加了允許離開脫硫步驟的煙道氣流的適當(dāng)部分朝向該煙囪減少了Cansolv工藝中捕獲的CO2量。選定的IGCC 植物基于案例B5B，不同之處在于繞過（部分或全部）水氣體變換反應(yīng)器，從而減少Selexol工藝中捕獲的CO2量。這個這些植物中潛在的CO2捕獲技術(shù)的主要成分被保存對整個過程進(jìn)行最小的修改。SC PC案例包括最新的成本和來自最近供應(yīng)商報價的性能信息，而IGCC的性能和成本是根據(jù)修訂版2報告中使用的舊引用，進(jìn)行標(biāo)準(zhǔn)調(diào)整將成本更新到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.
