CALS-technology for Production of Dibasic Lead Phosphite in Phosphoric Sludge Utilization

Abstract

Phosphoric sludge is the most harmful and dangerous of waste of phosphorus-containing substances, and its aggregated volumes, by rough estimates, total millions of tons. Therefore utilization of the that waste is now an acute problem and will bring rather notable contribution not only to national economies, but will also considerably improve ecological conditions (Bessarabov et al., 2010a). Development of industrial productions for processing of phosphoric sludge was carried out within the most modern and prospective system of computer support - CALS-technologies (Continuous Acquisition and Life Cycle Support). The task of the CALS is transformation of product life cycle to highly automated process by re-structuring of business processes included into it (Saaksvuori, Immonen, 2010). In development of advanced chemical productions it is shown that CALS-technologies and the main CALS-standard, ISO 10303 STEP, offer of a solution of a problem of electronic representation of the design information by means of use of the standardized integrated description of a product. The designer’s electronic description according to standard ISO 10303 STEP contains structure of categories, documents, statuses, groups of products with their versions, properties, classifications, etc (Molina et al., 1999). Marketing researches of the phosphoric industry waste utilization (Bessarabov et al., 2010b), system researches of innovative resources of leading enterprises making and utilizing phosphorus-containing production wastes (Bessarabov et al., 2010c) were carried out within the grant of European Community ECOPHOS ? INCO-CT-2005-013359, and also the flexible two-product scheme of phosphoric sludge utilization with obtaining of sodium phosphite and hypophosphite (Bessarabov et al., 2009, Klemeš et al., 2006) was developed. In the given work carried out under the contract of Ministry of Education and Science of Russia no. 11.519.11.5005, we considered the complex of three individual productions flowsheets of phosphoric sludge utilization, including sodium phosphite and hypophosphite, and also phosphoric sludge processing through sodium phosphite to dibasic lead phosphite.
