Material Selection using Multi-criteria decision making methods (MCDM) for design a multi-tubular packed-bed Fischer-Tropsch reactor (MPBR).

Description: The future of the fossil fuel supply is uncertain. For this reason, it is necessary the transition from a fossil based to a biobased for greenhouse gas emissions reduction targets, and climate change. In this regards, multi tubular packed-bed reactor Fischer-Tropsch (MPBR) appears has an essential technology to improve and reduce cost of operation. For design a MPBR, many studies has been used CFD for detailed evaluation of reaction systems. This research use Multi-criteria decision making methods (MCDM) for the material selection of a MPBR. This project focuses on the design for selecting an alternative material which best fits the technological requirements to make the pipes and the vessel of a MPBR and reduce the cost of production. The MCMD methods implemented are complex proportional assessment of alternatives with gray relations (COPRAS-G), operational competitiveness rating analysis (OCRA), a new additive ratio assessment (ARAS) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods. The criteria weighting was performed by compromised weighting method composed of AHP (analytic hierarchy process) and Entropy methods. The ranking results showed that ASME SA-106 and ASME SA-106 would be the best materials for the pipes and the vessel of a MPBR.
