Abstract Dry gasification oxy-combustion (DGOC) power cycle is a novel, zero-emission power production scheme. This work presents the detailed parametric study of various process performance variables namely gasifier temperature, gasifier pressure, fraction of recycle gas from combustor, molar gasification agents ratio, different type of sorbents on the process performance measured in term of product gas quality and quantity, total heat generated for power production and sulfur removal efficiency using the ASPEN Plus simulator. Various sorbents namely CaCO3, Fe2O3, MnO, CuO are considered for this study. Results shows that different sorbents posses different behavior. Temperature has significant affect on the DGOC performance. Fe2O3 is not a suggested sorbent in DGOC. CuO appears to be good sorbent in terms of temperature in the gasifier required or energy input required to the gasifier, and sulfur removal efficiency. MnO appears to be good sorbent in terms of syngas quality and total heat generated which was used to produce power by DGOC cycle.

使用 ASPEN Plus 模拟对干气化氧燃烧动力循环进行详细的参数研究

摘要 干气化氧燃烧 (DGOC) 动力循环是一种新颖的零排放发电方案。这项工作介绍了各种工艺性能变量的详细参数研究，即气化器温度、气化器压力、燃烧器循环气的比例、气化剂摩尔比、不同类型的吸附剂对工艺性能的影响，从产品气的质量和数量、总使用 ASPEN Plus 模拟器为发电和硫去除效率产生的热量。本研究考虑了各种吸附剂，即 CaCO3、Fe2O3、MnO、CuO。结果表明不同的吸附剂具有不同的行为。温度对DGOC性能有显着影响。Fe2O3 不是建议在 DGOC 中使用的吸附剂。就所需的气化器温度或气化器所需的能量输入以及硫去除效率而言，CuO 似乎是良好的吸附剂。就合成气质量和产生的总热量而言，MnO 似乎是良好的吸附剂，用于通过 DGOC 循环发电。
