TAILIEUCHUNG - Reference Document on Best Available Techniques in the Large Volume Organic Chemical Industry February 2003

VOCs from process vents are, where possible, re-used within processes but this is dependent on such factors as VOC composition, any restrictions on re-use and VOC value. The next alternative is to recover the VOC calorific content as fuel and, if not, there may be a requirement for abatement. A combination of techniques may be needed, for example: pre- treatment (to remove moisture and particulates); concentration of a dilute gas stream; primary removal to reduce high concentrations, and finally polishing to achieve the desired release levels. In general terms, condensation, absorption and adsorption offer opportunities for VOC capture and recovery, whilst oxidation techniques involve. | EUROPEAN COMMISSION Integrated Pollution Prevention and Control IPPC Reference Document on Best Available Techniques in the Large Volume Organic Chemical Industry February 2003 Executive Summary EXECUTIVE SUMMARY The Large Volume Organic Chemicals LVOC BREF Best Available Techniques reference document reflects an information exchange carried out under Article 16 2 of Council Directive 96 61 EC. This Executive Summary - which is intended to be read in conjunction with both the standard introduction to the BAT chapters and the BREF Preface s explanations of objectives usage and legal terms - describes the main findings the principal BAT conclusions and the associated emission consumption levels. It can be read and understood as a stand-alone document but as a summary it does not present all the complexities of the full BREF text. It is therefore not intended as a substitute for the full BREF text as a tool in BAT decision making. Document scope and organisation For the purposes of BAT information exchange the organic chemical industry has been divided into sectors for Large Volume Organic Chemicals Polymers and Fine Organic Chemicals . The IPPC directive does not use the term Large Volume Organic Chemicals and so offers no assistance in its definition. The TWG interpretation however is that it covers those activities in sections a to g of Annex 1 to the Directive with a production rate of more than 100 kt yr. In Europe some 90 organic chemicals meet these criteria. It has not been possible to carry out a detailed information exchange on every LVOC process because the scope of LVOC is so large. The BREF therefore contains a mixture of generic and detailed information on LVOC processes Generic information LVOC applied processes are described both in terms of widely used unit processes unit operations and infrastructure Chapter 2 and also using brief descriptions of the main LVOC processes Chapter 3 . Chapter 4 gives the generic origins and possible composition
