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...

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...

When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function as a fixed platform to which the crane is attached, therefore...

In this work, a switched-device power amplier using bias control is designed and realized. The PA operates at a frequency of 100MHz. Test results show that the PA achieves a PAE of 63% at −6dB power back-off and 60% at the peak output power of 40dBm. First, an overview of the state-of-the-art PA technology and performance in high PAPR...

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...

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...

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...

The offshore wind industry is a growing market in Europe due to the sustainable energy targets of European Union. In the coming years the Dutch government will invest in offshore wind farms at the North Sea. For a contractor like Boskalis the inclusion of favorable ecological conditions in designs is a unique selling point and can help to win...

Together Amsterdam Airport Schiphol airport and KLM form the largest chunk of the Dutch air transport industry. As the market for air transport in the Netherlands itself is too small, KLM developed a worldwide route network with many transferring passengers. Schiphol facilitates connecting passengers with the best possible experience. During...

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...
