An effective approach for lowering CO2 emissions from industrial processes is the absorption method of capture. Because high energy required to break bond carbamate ions during stripping process, intramolecular interaction (repulsive interaction) Ncarbamate-Ccarbamate was discovered be main interaction. Therefore, purpose this study examine amine-CO2 strength various molecules regeneration process using molecular dynamic modelling, as well explore diffusion coefficient amines. The results...

CO2 capture by absorption method is a promising way to realise reduction in the industrial process. To reduce cost of and desorption process, people are looking for efficient solvents.

The molar ratio of H2/CO (RHC) and high heating value (HHV) for gasification syngas are the crucial parameters a chemical synthesis process. Except conventional method by changing ratios O2/coal H2O/coal, is it feasible to improve quality controlling elemental components given coal fed into gasifier? To investigate this hypothesis, we focused on dual bed pyrolysis (DBPG) technology proposed operation char volatiles extraction change mass fraction gasifier. A two-step model coupling...

Fluid structure Interaction (FSI) is one of the emerging fields in numerical simulation and calculation multi-physics problems. FSI becomes crucial capturing large deformations offshore structures these are caused by vortex induced loads. imposes various challenges due to its complexity nature interaction between a fluid solid geometries requirements computational resources. In this paper, analysis conducted on cylindrical member which may be considered as leg an platform. The performed...

researchers. By using chaotic maps based random S-box selection, multiple substitution boxes can be used to reduce the correlation among adjacent pixels of an image but this key dependent nature methodology makes it vulnerable chosen plain text attack (CPA). To address these issues, a on propagating cipher block chaining (PCBC) with new diffusion technique has been proposed. PCBC is known CPA resistant. The effect first round being transferred next diffusion, when pixel replaced by last...

Coal plays an indispensable role in the chemical industry, which methanol from coal is a largely crucial part.In process of coal-to-methanol chain, large amount CO 2 emitted into atmosphere, should be captured and utilized.In this paper, firstly Aspen Plus software used to simulate whole production chain.The simulation results indicate that carbon footprint certain 3.01t /t methanol, then we compare processes with two cases are CCS (Carbon Capture Storage) CCU Utilization) P2G (Powerto-Gas)...
