Heating Value Reduction of LNG (Liquefied Natural Gas) by Recovering Heavy Hydrocarbons: Technoeconomic Analyses Using Simulation-Based Optimization

Heating Value Reduction of LNG (Liquefied Natural Gas) by Recovering Heavy Hydrocarbons: Technoeconomic Analyses Using Simulation-Based Optimization

by Iftekhar Abubakar KARIMI

LNG is expected to play a major role in global natural gas trade. Implementing a heating value adjustment unit within regasification terminal allows importing of LNG from diverse sources around the world, thus increasing the energy security of the importing country. In this study, we have developed a superstructure for heavy hydrocarbons removal (HHR) as a strategy to reduce the heating value...

High-throughput computational screening

High-throughput computational screening

by Jianwen JIANG

We report a computational study to screen a large collection of metal-organic frameworks (MOFs) for the separation of a ternary gas mixture (CO2/N2/CH4) toward the upgrading of natural gas. By integrating Monte Carlo and molecular dynamics simulations, the adsorption, diffusion and permeation of the gas mixture are predicted. The structure-performance relationships are established betwee...

Hydrogen Spillover in MOFs

Hydrogen Spillover in MOFs

by Hua Chun ZENG

Hydrogen spillover phenomenon is well-documented in hydrogenation catalysis but still highly disputed in hydrogen storage. Until now, the existence of hydrogen spillover through metal–organic frameworks (MOFs) remains a topic of ongoing debate and how far the split hydrogen atoms diffuse in such materials is unknown. Herein we provide experimental evidence of the occurrence...

Tuning the state-of-the-art numerical simulator for energy recovery from methane hydrates

Tuning the state-of-the-art numerical simulator for energy recovery from methane hydrates

by Praveen LINGA

Methane hydrates (MHs) have been considered as the future source of natural gas because of its vast global resource volume and high energy storage capacity. In order to recover energy from MHs safely and effectively, there is a need for a fundamental understanding on the dynamic behavior of MH formation and dissociation together with the associated fluids flow behavior in geological media. In...
