Intensifikasi Proses dalam Sistem Reaksi dan Pemisahan Dinamik
Abstract
Process Intensification (PI) presents a set of often substantially innovative and creative methods in process equipment design and operation method, which could bring considerable benefits in term of process performance. The process intensification in principle is a paradigm shift of thinking when compared to traditional processes. Transient reactors and separations are receiving increased attention due to its capability to influence the temperature and concentration profiles inside the fixed bed as well as main product recovery, leading to the possibility for improvement of conversion, selectivity, and recovery. The application of the transient fixed bed and membrane reactors is also gaining broad interest as an efficient method for energy saving, lower light-off temperature, and higher recovery. This technology may be considered as an alternative to various catalytic reactions in which heat storage and catalytic coverage can be manipulated for the process improvement. In this paper, possible operations and methods of fixed bed catalytic reactor and membrane operation are presented. Examples are given here for modulation of feed gas in catalytic converter and membrane, and application of reverse flow reactor. Overall, the process intensification opens a new way for improvement of process performance when proper design and operation can be developed.
