The separation was optimized for 8-column pseudo-SMB system with three column lengths (2.5, 5.0, and 10 cm) and three feed composition ratios (1/1/1, 1/2/1, and 2/1/2).
Table 3 presents the integrated PCDD to PCDF ratios for different feed composition ratios, R, for both oxygen rich and pyrolytic conditions.
The discharge dissipated power and the feed composition ([N2O]/[HMDSO] ratio) on film properties have been investigated by means of Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS) and Ellipsometry.
Parametric analysis is performed for both cases evaluating the impact of feed composition (water-to-ethanol ratio) and operative conditions of the membrane reactor (temperature and feed/permeate pressures) on performances and design parameters.
The effects of pressure drop equation, isotherm shape, adsorbent capacity, pressure ratio and feed composition on penetration distance, pressurization time and pressurization amount are assessed.
Comparisons are also made with recently reported experimental results, to demonstrate the capability of the model to predict the dependence of the syngas conversion and H2CO consumption ratio on feed composition and velocity.
That study focused on the application of membrane gas separation in CO2 processing with a general approach considering the effect and, eventually, the limitations offered by the main variables that affect the separation performance: the pressure ratio, the feed composition, and the mass transport properties (permeance and selectivity) of the membrane considered in the installation.
The process parameters such as total feed flow rate, reboiler temperature, palmitic acid feed composition, palmitic acid feed temperature, molar ratio of isopropanol feed to palmitic acid feed and reflux ratio were studied experimentally in the catalytic distillation column.
