A COMPARATIVE STUDY OF PHOSPHONATE AND PHOSPHORUS-FREE ANTISCALANT EFFICIENCY BY STATIC AND DYNAMIC METHODS. DO WE HAVE RELIABLE TOOLS FOR AN ADEQUATE REAGENT SELECTION?


Authored by Popov K


A relative ability of four industrial samples of phosphorus-free polymers (polyaspartate, PASP; polyepoxysuccinate, PESA; polyacrylic acid sodium salt, PAAS; copolymer of maleic and acrylic acid, MA-AA) and of two phosphonates (aminotris(methylenephosphonic acid), ATMP; 1-hydroxyethane-1,1-bis(phosphonic acid), HEDP) to inhibit calcium carbonate precipitation at a dosage 10 mg•dm-3 is tested in static experiments following the NACE Standard TM0374-2007 and in a dynamic modeоfevaporation plant for Caspian Sea water imitate. The reagent efficiency ranking following NACE Standard gives evidently a preference to phosphonates over polymers: ATMP~HEDP>PESA (400-1,500 Da) ~PASP (1,000–5,000 Da)>PAAS (3,000–5,000 Da) ~MA-AA. At the same time the kinetic tests exhibit the better efficiency of PESA and MA-AA: PESA>MA-AA>PAAS~HEDP>ATMP~PASP. Therefore, a lot of work is still needed to elaborate a system of laboratory tests for antiscalants in order to provide reliable assessment and selection on their way from laboratory to industry.

Production of Dimethylfuran as Liquid Fuel from Biomass Derived Carbohydrates -Recent Advances in Petrochemical Science -Juniper Publishers JUNIPER PUBLISHERS-RECENT ADVANCES IN PETROCHEMICAL SCIENCE PRODUCTION OF DIMETHYLFURAN AS LIQUID FUEL FROM BIOMASS DERIVED CARBOHYDRATES Authored by Nitinkumar SS Diminishing fossil fuel reserves and increasing global warming are the major problems faced by the world now. This demands sustainable sources of energy must resource required energy in the near future. Serious steps to restrict the existing concern and to find alternate energy sources have been the area of interest for the scientific community. On the contrary, our major concern is over availability and costs of petroleum feedstock's, which has given rise to a growing interest in alternative carbon sources such as natural gas, coal, biomass, and shale oil and tar sands. The conversion of renewable resources, such as biomass and organic wast...
