“…The compositions ranged from 0% to 100% water in MeOH. The temperatures ranged from 150 • C to 170 • C. The vapor composition was calculated with the Wilson activity model [33] with parameters from [34]. A STR with a total volume of 200 ml was filled with samples weighing 110 g. The sample was filled under ambient conditions and after sealing the STR the pressure was reduced to 150 mbar in 20 s via a vacuum pump.…”

“…The reaction was simulated, and the measured vapor compositions compared to the theoretical results. The vapor-liquid equilibria from [34] and the reaction kinetics as derived by Hosseininejad et al [20] were used. The reaction was stopped after 4 h. The goal was to demonstrate that the measurements are accurate enough to be used for process monitoring of high-pressure systems and fast enough to monitor multiple processes or sampling points.…”

A novel system for composition analysis in chemical plants at high temperatures and pressures has been developed. The system uses heated capillaries to extract and transport liquid and gaseous samples to a Fourier-Transform-Infrared-Spectrometer (FTIR) for analysis. The samples are extracted from pressure vessels at temperatures ranging from 20 to 190°C and pressures from 5 to 22 bar and analyzed via FTIR with a dead time of 5 to 10 seconds. The system was successfully used to monitor the dehydration reaction of methanol to dimethyl ether in a 170-hour long-term experiment. The system has a measurement range of 1E-4 mol mol-1 to 1 mol mol-1 and is accurate and fast enough for real-time product quality assessment and control in high purity chemical processes where inline measurements are challenging due to harsh environments.

“…9,11,12 A simulation of a reactive dividing wall column was performed by Kiss et al 12 and Gor et al 7 Along with stationary simulations, dynamic process intensification has also been investigated. 10,13 Within all of these investigations, different kinetic models were applied for process simulation. While some authors use their own developed kinetic models, others adopted literature kinetic models to their required working range.…”
