Aqueous Morpholine As a Potential Post-Combustion CO2 Absorption Solution

Nov 1, 2012

Krishna Mohan Jinka

Due primarily to high cyclic capacity and high absorption rates compared to other methods, aqueous amine based CO 2 capture has gained great interest for application to post-combustion CO 2 capture. While aqueous amines have a long history for acid gas removal, challenges remain for the commercial...

Thermodynamics Studies of Metal Oxides Conversion for CO2 Sequestration In Steel Industry

Oct 18, 2011

Hui Li

Due to the concerns of “global warming”, CO2 sequestration from steel industry are becoming more and more important for the environments FeCO3, one of component for steel, was selected to investigate in order to design suitable processing to sequestrate the CO2 at the steel plant. It was found that...

Evaluation of Key Parameters for Designing Effective Water Curtain Systems for LNG Facilities Using Computational Fluid Dynamics

Apr 5, 2012

Byung Kyu Kim, Byung Kyu Kim

Concerns over public safety and security of an accidental LNG spill have motivated the continued study of LNG mitigation measures. Forced dispersion of LNG vapors using a water curtain system has been proven to be effective in reducing the LNG vapor exclusion zone by enhancing the dispersion...

Emissivity of Cracking Furnace Coils, Novel Temperature Measurement Solutions for Cracking Furnaces

Apr 5, 2012

Ben Brown

Accurate measurements of skin temperature on cracking furnace coils have become necessary for improved process control. Infrared devices have proven inaccurate for measuring skin temperatures on furnace coils. The inaccuracy has been driven in large part by an uncharacterized and misunderstood...

Dynamic Simulation: Value During LNG Process Design and Beyond

Apr 4, 2012

Kenneth V. Allsford

A contributor to complex/large project management difficulty is uncertainty gaps – gaps between the information required and that readily available within the project organization. Moreover, for large projects, information is generally spread among many professional personnel across multiple...
