In postcombustion, the carbon dioxide gas is captured after combustion using a solvent, sorbent, or membrane. Precombustion is used in integrated gasification combined cycle (IGCC) where carbon dioxide is captured from the syngas before it enters the gas turbine. Carbon capture mainly consists of three methods: (1) precombustion (2) postcombustion (3) oxy-fuel combustion with CO 2 recycle and capture. One promising technology that can help reduce huge emissions from the fossil fuel power plants is carbon capture, utilization, and storage (CCUS). According to a recent research, we have barely 11 years to drastically reduce our greenhouse gas emissions to avoid the detrimental impacts of the global temperature increase by 2РІВРЉ equivalent to a carbon dioxide level of 450РІР‚вЂ°ppm in the atmosphere. The amount of carbon dioxide in the atmosphere today is more than what it was 800,000 years ago according to ice core records document. The CO 2 emission from the US power generation for the year 2017 was 1.8 billion tons. These combustion processes generate carbon dioxide which is a potent greenhouse gas. Fossil fuel combustion generates 2/3 of the electricity in the US, and this will not change significantly till 2040 because of the abundance of cheap natural gas in the US. IntroductionР”Р„bout 1/3 of the US greenhouse gas emissions is due to the production of electricity. This study shows that the Allam cycle power plant integrated with an ASU is controllable with the proposed control strategy under a tightly integrated configuration. Controller set point change, power ramp down, and natural gas composition change were studied, and key plant performance indicators were monitored and analyzed. Regulatory and advanced PID controllers were implemented for major equipment to meet operation objectives. The steady-state model developed agrees with the model developed by Net Power.

In this study, Aspen Plus Dynamics was used to model the integrated Allam power plant/air separation unit (ASU) with a high degree of heat and work integration. The Allam cycle, a new oxy-fuel power cycle that emits virtually no CO 2 and NO x, is inherently integrated with an air separation plant. Electricity and heat generation account for around 25% of this greenhouse gas emission. The unprecedented rise in carbon dioxide levels due to anthropogenic activities, if left unchecked, can lead to increased global warming.
