Termokontaktnyy Piroliz Uglevodorodnogo Syr'ya Na Zhelezooksidnom Ogarke: Termodinamicheskie Issledovaniya I Tekhnologicheskie Osnovy Protsessa Firdavis Murtazin Russian edition

Nizshie olefiny yavlyayutsya tsenneyshim syr'em neftekhimii. Oni primenyayutsya v proizvodstve razlichnykh polimerov, spirtov, plastmass i drugikh produktov. Prichem mirovoe potreblenie etikh produktov nepreryvno rastet, chto vyzyvaet postoyannoe uvelichenie sprosa na nizkomolekulyarnye nepredel'nye uglevodorody. Osnovnym istochnikom polucheniya nizshikh olefinov yavlyaetsya gomogennyy piroliz v trubchatykh pechakh. Dannaya tekhnologiya imeet sleduyushchie nedostatki: raskhody na pechi sostavlyayut tret' investitsiy v ustanovku piroliza, vysokaya energoemkost' protsessa, periodicheskaya ostanovka pechey na vyzhig koksa, ispol'zovanie dorogostoyashchikh ingibitorov. V svyazi s etim predstavlyayut interes razrabotki al'ternativnykh tekhnologicheskikh protsessov. K ikh chislu otnosyatsya i termokontaktnye protsessy piroliza (TKP), razrabotka kotorykh nachalas' eshchye v 50-kh godakh XX veka. Kak pravilo, nedostatkami prakticheski vsekh razrabotannykh na dannyy moment protsessov TKP yavlyayutsya nizkie tekhniko-ekonomicheskie pokazateli protsessa. Takim obrazom, razrabotka novykh tekhnologicheskikh resheniy dlya protsessa TKP v sochetanii s podborom optimal'nogo teplonositelya yavlyaetsya aktual'noy i predstavlyaet prakticheskiy interes.
