Analysis of Two Dense Phase Carbon Dioxide Full-Scale Fracture Propagation Tests
Volume 3: Materials and Joining; Risk and Reliability, 2014Two full-scale fracture propagation tests have been conducted using dense phase carbon dioxide (CO2)-rich mixtures at the Spadeadam Test Site, United Kingdom (UK). The tests were conducted on behalf of National Grid Carbon, UK, as part of the COOLTRANS research programme.

Alterations of molecular properties of lipoxygenase induced by dense phase carbon dioxide
Innovative Food Science & Emerging Technologies, 2009Abstract Alterations of molecular properties of lipoxygenase (LOX) induced by dense phase carbon dioxide (DPCD) were analyzed using transmission electronic microscope (TEM), SDS-PAGE and native-PAGE, far UV-circular dichroism (CD) and fluorescence spectroscopy.

Modeling the inactivation of Salmonella typhimurium by dense phase carbon dioxide in carrot juice
Food Microbiology, 2010The inactivation of Salmonella typhimurium inoculated into acidified carrot juice subjected to dense phase carbon dioxide (DPCD) was investigated. The pressures in the study were 10, 20 and 30 MPa, the temperatures were 32, 37 and 42 degrees C, and the treatment time was 5-90 min.

This chapter describes the functions of CO2 as a reaction promoter in multiphase catalytic reactions. Carbon dioxide can play more significant chemical roles in organic synthetic reactions than expected from its rather inert nature. Under pressurized conditions, a certain amount of CO2 is dissolved in organic liquid phase (substrate, solvent), has ...

APPLICATION OF DENSE PHASE CARBON DIOXIDE PROCESS IN FOOD PRESERVATION
Dense Phase Carbon-dioxide (DPCD) is a non-thermal food preservation technique for highly heat-sensitive, perishable food commodities like fruit juices, beverages, and other liquid foods. It is a continuous process, which utilizes pressurized CO2 (pressure 1/10th to that of the HHP) with a mild temperature of 30-50°C in food processing.Kathyayini H S +3 more

Inactivation of polyphenol oxidase from Pacific white shrimp by dense phase carbon dioxide
Innovative Food Science & Emerging Technologies, 2011Abstract The inactivation of polyphenol oxidase (PPO) from Pacific white shrimp exposed to dense phase carbon dioxide (DPCD) treatment was investigated. PPO activity showed a dramatic loss at 4–25 MPa and 37 °C. At the lower pressure (4–15 MPa), the experimental data of inactivation followed the first-order reaction kinetic model, the pressure ...

Polymers with Multiple Ligand Sites for Metal Extractions in Dense-Phase Carbon Dioxide
Industrial & Engineering Chemistry Research, 2001We have synthesized a series of CO2-soluble polymeric extractants with multiple ligand sites for CO2-based metal extractions. The CO2-soluble polymers were prepared via free-radical copolymerization of a fluorinated acrylate with a series of acrylate- or styrene-based monomers functionalized with ligand sites or ligand precursors.

A simple function for the solubility of water in dense-phase carbon dioxide
International Journal of Greenhouse Gas Control, 2015Abstract Knowledge of water solubility in dense-phase carbon dioxide is important in CCS projects. An explicit function for the solubility is determined as a function of temperature and pressure. The determination of the function is not based on thermodynamic model assumptions.
