2021年8月1日 · Supercritical carbon dioxide (sCO 2) semi-closed cycle is an advanced, efficient, and economical power generation system that can meet the needs of low cost and efficient utilization of coal and low carbon emissions. The Advanced System for Process Engineering software (Aspen Plus) was used to simulate different sCO 2 systems.

The Aspen plus software was applied to establish the mathematical model for supercritical carbon dioxide brayton cycle and the thermal power system of a 600 MW unit was calculated. The effects of several factors such as compression split coefficient, turbine split coeff...

本文首先采用Aspen HYSYS与Aspen Plus软件分别建立了三种循环模型:简单循环、再压缩循环和分流再压缩循环;并使用三种物性方法对每种循环进行了模拟;对比实验室的数据,研究了不同物性方法的模拟精确度,数据表明Aspen Plus软件下的REFPROP物性计算方法精确度较高。 然后在不同的工况参数下,使用该物性方法计算对比了三种循环在相同工况下的循环效率,结果证实:为获得高效率,回热尤为重要。 最后,以再压缩循环模型为基础,在不同的回热条件下,研究了循环中五个主要 …

Aspen Plus and Hysys software are commercially validated codes that provide reliable thermodynamic analysis and a wide range of property method calculations, such as REFPROP, which is the best property method available for calculating SCO2 properties at temperatures and pressures required for high efficiency Brayton cycles.

The cycle was modeled in Aspen Plus® to determine stream conditions and heat and power duties. These were used to estimate the cycle efficiency. To better understand the dependence of the cycle performance on the operating conditions, …

Abstract:Compared with the traditional thermal power generation system, the supercritical carbon dioxide (SCO2) Brayton cycle power generation system has the advantages of small system...

Commercial software packages such as Aspen Plus rely on EOSs to inform and predict states of matter and interactions between matter under given conditions. Direct fired critical carbon dioxide systems offer unique challenges for standard equation of states found in the literature.

2022年5月15日 · Research on the analysis of a cycle thermodynamically to be integrated into a turbofan jet engine will be highlighted in this paper. The analysis will be conducted via simulation within the Aspen...

2022年2月1日 · Novel concept for supercritical CO 2 -Haber-Bosch integrated process is presented. Comprehensive process simulation in Aspen Plus of two distinct design cases. Techno-economic analysis at scales of 1.5, 15, and 150 ton h −1 NH 3 is performed. Both cases of the integrated process show profitability at scales >5 ton h −1 NH 3.

On this research, the results of an analysis made of a Supercritical Carbon Dioxide (sCO2) Recuperated Closed Brayton Cycle (RCBC) done by performing theorical calculations and comparing it to the results obtained with the use of the software ASPEN Plus will be presented.
