33 3.2.2 Modelling and Simulation of Petlyuk Columns. 33 3.2.1 Minimum Energy Mountain Diagram.
Date and signature:ĪCKNOWLEDGEMENT.iv ABSTRACT. However, all the configurations are found to be highly sensitive to both raw materials as well as product prices. Conclusions and recommendations: Out of the six alternative cases studied, three conventional and three with Petlyuk columns, the Petlyuk column producing LPG and natural gasoline, is found out to be economically most profitable. In order to have an economic process, instead of using refrigerant it is suggested to use sea water, at 10oC for condenser. Thus, the steam used for reboiler of the column is considered to be generated as part of steam generation for the whole plant. The plant will be built in Norway as a part of a gas processing plant. The process is studied using conventional columns and also Petlyuk columns as alternative to the conventional ones.
