  • Analysis of water soluble polymers using linear size exclusion HPLC columns and a semi-micro SEC system

    One of the most widely used water-soluble polymers is Polyvinylpyrrolidone (PVP). For more than 70 years it is applied in a variety of applications in medicine, pharmacy, cosmetics and industrial production. PVP binds to polar molecules exceptionally well. It supports the solubility of tablets in water, makes the glue stick adhesive and plays an essential role in the production of membranes. In ceramic, paper and dye applications, it produces visual effects such as gloss and brilliancy. As a food additive, PVP is a stabilizer (E1201). A characteristic feature of a certain polymer is its molecular weight distribution curve, which is usually obtained by SEC Analysis more

  • Battling Corrosion in Refineries

    Corrosion in refinery operations has been, and still is, the subject of many studies, papers, courses and web forums. Although a lot of what has been written shows that significant progress in understanding corrosion has been made, it also makes it more

  • Do you see the complete picture?

    Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact th more

  • Hydrogenation and High Pressure Reaction Monitoring

    This presentation discusses the implementation of Fourier Transform Infrared (FTIR) reaction monitoring technology to provide knowledge and understanding about key reaction parameters that enabled successful hydrogenation. Typically, hydrogenations encounter challenges with reaction kinetics, sele more

  • Carbon Dioxide Utilisation

    Carbon dioxide utilisation processes convert CO2 into commercially viable products such as chemicals, polymers, building materials and fuels. Carbon dioxide utilisation is an emerging technology which can contribute to the reduction of greenhouse gas emissions by the use of CO2 to manufacture useful more

  • US Deficit Reduction Plans Affecting Profitability of the Petrochemical Industry

    Introduction A recent energy speech by US president Barack Obama outlining government intentions to increase fossil fuel tax – citing the fiscal deficit and political unrest in the Middle East as reasons and rejecting the solution of increased domestic crude oil production – has evoked a strong re more

  • Monomer World - May 2011

    Introduction The global monomer industry experienced a significant reduction in demand for downstream derivatives in May 2011. In most regions, this reduced demand caused the prices of monomers to significantly decrease. Shell’s Pulau Bukom (Singapore) ethylene and propylene unit are operational on more

  • Global and China 1,4-Butanediol (BDO) Industry Report, 2010-2011

    1, 4-butanediol (BDO) is an important raw material for basic organic chemicals and fine chemicals. Subject to the financial crisis, the global BDO capacity has showed sluggish growth, up merely 3.7% year on year in 2010. Due to high technology thresholds and limited raw material sources, the BDO pro more
