Ultrasound intensified CO2 desorption from pressurized loaded monoethanolamine solutions. I. parameters investigation and modelling
An experimental study of CO2 hydrate formation in the presence of chemical promoters
Morphology and rheology of PP/POE blends in high shear stress field
Polypropylene (PP)/ Polyolefin Elastomer (POE, ethylene-octene copolymer) blends with varying weight percentages of POE, were prepared in a twin-screw extruder and molded through high shear rate injection molding process. The morphologies and rheology of the PP/POE blends were systematically...
Mass Transfer Kinetics of CO2 in Loaded Aqueous MEA Solutions
The kinetic mass transfer between partially loaded MEA aqueous solutions and CO2 were measured in absorption experiments over a temperature range 303.15 – 313.15 K, MEA concentrations 3 M and 5 M, and a partial loading range 0.05 –0.30 mol/mol. The measurements were conducted by a stirred cell using...
The Activator Mechanism of Piperazine in Aqueous Methyldiethanolamine Solutions
Piperazine (PZ) is added to aqueous methyldiethanolamine (MDEA) solutions to achieve a greater CO2 absorption in CO2 capture technology. It is referred to as “activated MDEA solutions” in the industry. However, does PZ really activate rate the CO2 absorption of MDEA, or do PZ and MDEA just have...
Ultrasound enhanced CO2 Stripping from Lean MEA Solution at Pressures from 1 to 2.5 bar(a)
Ultrasound was introduced to assist CO2 stripping from lean 30 wt% MEA aqueous solutions in a reboiler. The effect of ultrasound on CO2 stripping was investigated at 2.5 bar(a) under two pressure control methods, solenoid operated on/off valve (OOV) and manual needle valve (NV) method. The results...
