Hydrate technology for the concentration of aqueous salt solutions using fluorinated refrigerants.
(2019)The world is facing a challenge with the scarcity of fresh water, due to an increase in the world population and the large expansion of industrial projects. This results in greater demand for fresh water. In such a scenario, ... -
Solubility studies of carbon dioxide in novel hybrid solvents using a new static synthetic apparatus.
(2019)The use of alkanolamine solutions in removing acidic gases from natural gas is common in the industry, but such technologies have disadvantages which include amongst others, solvent loss, corrosion and high heat consumption. ... -
Predictive solvent and anti-solvent selection method for pharmaceutical and biological products and intermediates.

Laser and ultrasound radiation pretreatment of cellulose in dissolving wood pulp.
(2017)Dissolving wood pulp (DWP) refers to wood extracted, chemically refined bleached pulp that comprises more than 90% pure cellulose. This type of pulp is mainly utilised for the production of various cellulose derivatives ... -
Pyrolysis-gas chromatography/mass spectrometry study of chromophores in dissolving wood pulp.
(2018)Dissolving wood pulp (DWP) is bleached wood pulp that contains high cellulose content, typically >95%. The bleaching is done to remove remnants of lignin and hemicelluloses that are not necessary for the final DWP. The ... -

Applications of fluorocarbons for supercritical extraction in the petroleum industry.
(2016)The majority of supercritical processes utilise carbon dioxide (CO2) as the principal solvent, because CO2 has many attributes that make it an ideal supercritical fluid (SCF) solvent. This study investigates the possibility ... -
Application of gas hydrates in cold storage technology : experimental study and thermodynamic modeling.
(2015)The ever-increasing demands for air conditioning technology especially in residential areas results in a severe imbalance between power generating utilities, especially during peak usage hours. To provide the required peak ... -

Unlike interactions in simulated methane clathrate hydrates.
(2014)Clathrate hydrates are an ice-like substance consisting of networks of water molecules, held together by hydrogen bonds, enclosing trapped gas molecules. Natural gas clathrate hydrates (in which the trapped gas species ...
