This work presents the heterogeneous kinetics of the reaction of CH 3 SCH 3 (dimethyl sulphide, DMS) with O 3 (ozone) in aqueous solution at different ionic strengths (0, 0.1 and 1.0 M NaCl) using the wetted-wall flowtube (WWFT) technique. Henry's law coefficients of DMS were determined on pure water and on different concentrations of NaCl 5 (0.1 M–4.0 M) in the WWFT from UV spectrophotometric ...

A recently published revision of the absorption cocfficienLs for oxygen in water has prompted a reinvestigation of the subject by a new microgasometric technique. A known volume of gas-free water (approximately 1 ml) was brought into contact with oxygen at constant pressure and temperature. The oxygen uptake and the amount of water were measured with a micrometer burette. The results obtained a...

In natural gas treatment, the removal of CO2 and H2S in acid gases is a critical concern. There are various purification technologies that can be used for the removal of acid gas impurities. Absorption of acid gas into amines is one preferred method in gas industries. In the past, single amines was used, but recently in order to improve absorption performance, mixed amines with different solubi...

This paper proposes an improvement on the recently introduced Henry Gas Solubility Optimization (HGSO) metaheuristic algorithm that simulates Henry’s gas law (i.e., concentration of a sample in liquid solvent is proportional to phase). As improvement, we apply quantum theory instead standard procedure used HSGO for updating solutions. The proposed named as Quantum HGSO (QHGSO) this paper. sugge...

solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. therefore,...

Inverse gas chromatography (IGC) represents a unique refinement of a classic chromatographic method has the potential to unlock some of the more difficult to measure physicochemical properties of pharmaceutical materials such as powder surface energies, acid/base/polar functionality of surfaces, diffusion kinetics, solubility parameters, surface heterogeneity and phase transition temperatures/h...
