Since 2012, the polymeric resin Lewatit R VP OC 1065 has been investigated for removal of CO2 from various process streams and air. The present article focuses on the deactivation mechanism of the resin with SO2 and a work around. This is important for CO2 capture from flue gas of coal-fired power plants and fuel oil. The deactivation of the...

Since 2012, Lewatit R VP OC 1065 was reported as a promising material for direct air capture of CO<sub>2</sub>. However, deactivation at a high pressure of CO<sub>2</sub> at 120 °C was reported with detrimental effects on its application. In this study, using density functional theory calculations, a quantitative description of the...

Lewatit R VP OC 1065 is a promising material for direct air capture of CO<sub>2</sub>. However, it was found that serious oxidative degradation already started from 80 °C. In this DFT study, oxidative degradation is described as a series of well-known reactions in air-oxidation chemistry. Oxidation of the resin starts with the formation of an...

Iron sulphide scale, which exists in different forms, is common in sour oil and gas production wells. Iron sulphide hard scales are difficult to remove with acids, requiring mechanical intervention or the replacement of the production tubing. An environmentally friendly formulation with a high pH is proposed for the removal of both soft and...

A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales (including pyrite), consisting of a chelating agent diethylenetriaminepentaacetic acid (DTPA) at high pH using potassium...

Several reactions, known from other amine systems for CO2 capture, have been proposed for Lewatit R VP OC 1065. The aim of this molecular modeling study is to elucidate the CO2 capture process: the physisorption process prior to the CO2-capture and the reactions. Molecular modeling yields that the resin has a structure with benzyl amine groups...

Natural gas, synthesis gas, and flue gas typically contain a large number of impurities (e.g., acidic gases), which should be removed to avoid environmental and technological problems, and to meet customer specifications. One approach is to use physical solvents to remove the acidic gases. If no experimental data are available, the solubility...

Crown-ethers have recently been used to assemble porous liquids (PLs), which are liquids with permanent porosity formed by mixing bulky solvent molecules (e.g., 15-crown-5 ether) with solvent-inaccessible organic cages. PLs and crown-ethers belong to a novel class of materials, which can potentially be used for gas separation and storage, but...

Cation exchange is a powerful tool for the synthesis of nanostructures such as core–shell nanocrystals, however, the underlying mechanism is poorly understood. Interactions of cations with ligands and solvent molecules are systematically ignored in simulations. Here, we introduce the concept of pseudoligands to incorporate cation-ligand-solvent...

When the new locks of the Panama Canal are finished in 2015 Post Panamax vessels are able to sail through the Panama Canal. This will increase the container traffic intensity through the Caribbean. China Harbour Engineering Company (CHEC) wants to anticipate on this expansion of the Panama Canal by investing in a US$1.5 billion transshipment...
