Greenhouse gases (GHG) are a serious threat to humans and environment. Greenhouse gases have been different sources, but main factors are fossil fuels, industrial processes, deforestation and agriculture. What is now more than ever before should be considered according to the role of forests and rangelands in atmospheric carbon sequestration? Carbon sequestration is to changes in atmospheric ca...
We have conducted a detailed analysis of costs associated with today’s technology for CO2 separation and capture at three types of power plants: integrated coal gasification combined cycles (IGCC), pulverized coal-fired simple cycles (PC), and natural gas-fired combined cycles (NGCC). The analysis was based on studies from the literature that analyzed the economics of capturing CO2 emitted at p...
The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas and produces a separate liquid CO2 product. This project focuses on the energy-storing version of this process, CCC ESTM. During off-peak hours, CCC ESTM generates more refrigerant than is needed for the process, which is stored in an insulated vessel as a liquid at the l...
Drawbacks of current carbon dioxide capture methods include corrosivity, evaporative losses and fouling. Separating the capture solvent from infrastructure and effluent gases via microencapsulation provides possible solutions to these issues. Here we report carbon capture materials that may enable low-cost and energy-efficient capture of carbon dioxide from flue gas. Polymer microcapsules compo...
Carbon dioxide capture process has been simulated and studied under different process conditions. It has been shown that several process parameters such as lean amine temperature, number of adsorber stages, number of stripper stages and stripper pressure affect different process conditions and outputs such as carbon dioxide removal and reboiler duty. It may be concluded that the simulation of c...

Carbon dioxide capture from ambient air could compensate for all carbon dioxide emissions to the atmosphere. Such capture would, for example, make it possible to use liquid, carbon-based fuels in cars or airplanes without negatively impacting the climate. We present a specific approach based on a solid sorbent in the form of an anionic exchange resin, that absorbs carbon dioxide when dry and re...
Carbon capture and storage (CCS) is seen as one of the key technologies for cutting CO2 emissions from coal power plants. It is proposed that carbon capture and storage could reduce CO2 emissions to the atmosphere from a modern power plant by approximately 80-90%. Building and operating infrastructure for capturing, transporting, and storing CO2, however, is forecast to be expensive. To gain a ...
