Ökologische Bewertung von Produktionsprozessen in Mehrproduktbatchanlagen

Abstract

Für die Gestaltung nachhaltiger Produktionsverfahren in allen Branchen der Prozessindustrie sind neben sozialen und ökonomischen auch ökologische Aspekte von entscheidender Bedeutung. Vorgestellt wird ein Ansatz auf Basis eines 3-Ebenen-Modells, der die Analyse von Produktionsprozessen in Mehrproduktanlagen im Hinblick auf Energie-und Ressourcenverbrauch verbunden mit ökologischen Betrachtungen ermöglicht sowie die Identifizierung und Quantifizierung von Verbesserungspotenzialen unterstützt. Der Ansatz ist modular aufgebaut und basiert auf einer Stoffstromnetzmodellierung der betrachteten Prozesse.For a sustainable process design in the chemical, specialty chemical, and pharmaceutical industries, ecological aspects alongside the social and economic ones play a significant role. An approach based on a three level model is presented that allows an analysis of production processes in multi-product plants with respect to consumption of energy and resources combined with ecological assessment. The approach has a modular structure and builds on a material flow modeling of the assessed processes.

Use of Wire Matrix Inserts in Thermosiphon Reboilers in the Lower Operating Range

“…The examples given above for the assessment of new technologies result in diverging statements on the apparatus influence and highlight that data gaps for individual life cycle phases and the limited consideration of these phases do not allow a generally valid statement regarding the influence on the ecological performance of individual production processes. For the consideration of the influence caused by additional installations in an apparatus, the approach of the ILCD-Handbook [20] as well as by Wesche et al [30] will be used within the present investigation. Of the apparatus, its manufacturing materials as well as their related expenditures are assessed, whereas the influence resulting from the implementation of a new technology on the production process is determined via flow sheet simulation (FSS) to ensure a high level of data accuracy.…”

“…This includes both the type and quantity of the equipment material. In order to determine the annual ecological expenditures under consideration of the equipment life cycle, the annual plant-related expenditures are determined according to the approach of Wesche et al [30]. For this purpose, the procurement as well as maintenance over the useful life and disposal or recycling are recorded.…”

Estimation of Efficiency Potentials Generated by Innovative Equipment Technologies

“…A suitable approach, the 3‐level model, was developed by Wesche et al. in the framework of the InnovA 2 project. It is based on breaking processes apart into different levels of detail following a modular concept (Fig.…”

“…For this, an average of 6000 h a −1 of operation with a capacity utilization of 70 % is assumed. Additionally, the expenditures for service and maintenance over the equipment lifetime are considered as shown in and assumed to be constant.…”
