چکیده
The Texas Carbon Management Program is preparing a Front-End Engineering Design (FEED) of the PZASTM (Piperazine with Advanced StripperTM) for CO2 capture at natural gas combined cycle power plant in West Texas. This paper develops absorber design system and studies operational strategies response to ambient temperature swing. uses 2 trains, each train integrates absorption water-wash section one column. Each column has cross-section area 174 m2 consists 3 sections MellapakPlus® 252Y structured packing. Packing heights are 3, 4.9, 2.7 m from top bottom. A pump-around intercooler applied bottom bed circulates solvent eliminates direct contact cooler. baseline removal rate 90% will vary between 78% temperature. air cooling eliminate water usage. balance be managed by operating wash high circulation (1300 kg/h) condense during night make up loss day. proposed reduces capital cost minimizing packing height eliminating cooler (DCC), improves energy lowering intercooling increasing rate.

Functionalized Polymeric Membranes for CO2 Capture
Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...
متن کاملOptimization of CO2 capture process with aqueous amines using response surface methodology
Amine is one of candidate solvents that can be used for CO2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO2 recovery plant for post-combustion CO2 removal. For each amine solvent, ...
متن کاملExperimental and Computational-chemistry Study on Effect of Piperazine as a Promoter for CO2 Capture Solution
It is well known that small amount Piperazine (PZ) enhance the CO2 absorption properties of tertiary amine aqueous solution. Because the tert-amine has the lower heat of reaction, the blended amine solution, tert-amine with PZ, is attractive for low energy absorbent. There are some reports about the investigation of the mechanism of the blended amine solution, however, there still a difficulty ...

Carbon dioxide is one of the major greenhouse gas (GHG) contributors. It is an obligation of the industry to reduce the amount of carbon dioxide emission to the acceptable limits. Tremendous research and studies are reported in the past and still the quest to find the suitable and economical solution of this problem needed to be explored in order to develop the most plausible absorber for carbo...
متن کاملEnvironomic optimal design of power plants with CO2 capture
Life cycle impact assessment indicators are integrated for studying the process integration of renewable resources and CO2 capture and storage (CCS) in power plants. Besides the expected reduction in global warming potential (GWP), CCS induces energy and cost penalties. This paper presents a systematicmultiobjective optimisation framework for the optimal design of power plants with CO2 capture ...
