Abstract:This paper presents an application of the improved pinch methodology by performing a simplified exergy analysis in a real-size ammonia plant. Besides the well known pinch technics like composite curves and grand composite curve, the improved approach with the extended grand composite curve was implemented. The latter presents the most energy intensive units in the process separated from the process background as well as the direct transfer of enthalpy from hot utilities to cold utilities. Based on this presentation the synthesis of modified heat exchanger network was performed which results in considerable decrease of utilities demand.
Keywords:chemical engineering, process design, exergy analysis, ammonia plant, pinch methodology, extended hrand composite curve method, enthalpy exchange, distillation column, heat exchanger network

Title:Neposredni prenos entalpije med procesnimi pogonskimi sredstvi
Abstract:V članku je opisana uporaba izboljšane metodologije uščipa pri energetski študiji procesa pridobivanja amoniaka. Ob znanih metodah, kot sta metodi sestavljenih krivulj in velike sestavljene krivulje, je uporabljena tudi metoda razširjene velike sestavljene krivulje, ki energijsko intenzivne procesne enote predstavlja ločene od preostalih procesnih tokov in ponazarja tudi neposredni prenos entalpije med vročimi in mrzlimi pogonskimi sredstvi. Na osnovi te predstavitve so bile raziskane interakcije reaktorja in destilacijske kolone s preostalim procesom ter predlagane izboljšave procesne sheme, s katerimi je mogoče dosegati znatni prihranek pogonskih sredstev, 3,6 MUSD/a z zelo kratkim vračilnim rokom 4 mesecev.
Keywords:procesna tehnika, načrtovanje procesov, energetska študija procesa, pridobivanje amoniaka, metodologija uščipa, metoda razširjene velike sestavljene krivulje, prenos entalpije, destilacijske kolone, procesna shema
