Description
The aim of the second study of coupling the HTR module to process plants consistsed in developing concepts for potential plants and analysing them again for their technical and economic feasibility. At each of the three process plants, heat is coupled in by a He/He intermediate heat exchanger. This principle of heat coupling was consistently aimed at - in order to keep the expensive nuclear part of plant coupling as small as possible, and - in order to avoid that primary helium can get into the process plants, just as vice versa process media into the HTRM-helium circuit. For refineries this principle is easy to comply with because of the low process temperatures of below 600deg C. For aluminium oxide production which conventionally requires a temperature of about 950deg C, calcination tests were made at lower process temperatures, and parallely the feed-in of heat to reach the highest process temperature through electric heating was studied. For petrochemistry, heat transfer during naptha cracking was closely analysed. (orig./GL)

Die zweite Studie zur Kopplung des HTRM mit Prozessanlagen hatte zum Ziel, Konzepte fuer potentielle Anlagen auszuarbeiten und diese nochmals auf ihre technische wie wirtschaftliche Durchfuehrbarkeit zu analysieren. Die Waerme wird bei jeder der drei Prozessanlagen ueber einen He/He-Zwischenwaermetauscher eingekoppelt. Dieses Prinzip der Waermeeinkopplung wurde konsequent angestrebt, um den teueren nuklearen Teil der Anlagenkopplung so gering wie moeglich zu halten und um zu vermeiden, dass primaeres Helium in die Prozessanlagen gelingen kann, genauso wie umgekehrt Prozessmedien in den HTMR-Heliumkreislauf. Bei Raffinerien ist dieses Prinzip durch die niedrigen Prozesstemperaturen, unter 600deg C, leicht einzuhalten. Fuer die Aluminiumoxid-Herstellung, die konventionell eine Temperatur von ca. 950deg C erfordert, wurden Kalzinierversuche bei tieferen Prozesstemperaturen durchgefuehrt und parallel die Zufuehrung der Waerme zum Erreichen der hoechsten Prozesstemperatur ueber elektrische Beheizung untersucht. Bei der Petrochemie wurde die Waermeuebertragung waehrend der Naphtha-Spaltung genauer analysiert. (orig./GL)
