“…Finally, considering the entrance/exit effect, the actual value of Δ P /Δ L G will be less than a few mbar/m, while the actual value of Δ P /Δ L L of the HF-6 module is less than 25 mbar/m. These values are within the acceptable range for the structured packing materials used in the distillation application …”

“…If we assume that the intercepts at the y -axis reflect the entrance/exit effects, this effect on the liquid side (∼21 mbar/m) is slightly larger than that on the vapor side (∼16.5 mbar/m). After taking them into account, the values of Δ P /Δ L G drop below 10 mbar/m, which meets the prerequirement of any potential structured packings used in the distillation application. , …”

“…In the current scale, the NTU is 3–4, and max internal flow is <400 g/min. In general, industry wants to see that newly developed packing materials achieve 7–10 theoretical stages of separation and an internal flow on the order of >10 kg/min for the results to be meaningful at their scale of operations . As the scale is further increased, in addition to the channeling problems and pressure drops in both phases, how to scale up (one long unit vs a battery of short units) needs to be investigated.…”

Following the conceptual demonstration of high separation efficiency and column capacity obtained in olefin/paraffin distillation using hollow fiber structured packings (HFSPs) in a bench scale (J. Membr. Sci. 2006, 2007, and 2010), we scaled-up this process with a 10-fold increase in the internal flow rate and a 3-fold increase in the module length. We confirmed that the HFSPs technology gives high separation efficiency and column capacity in iso-/n-butane distillation for 18 months. We systematically investigated the effects of packing density, concentration of light component, reflux ratio, and module age on the separation efficiency and operating stability. Comprehensive characterizations using scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA) were carried out to probe the changes in the morphological, thermal, and mechanical properties of polypropylene (PP) hollow fibers over the aging process. The results suggest that after a long-term exposure to light hydrocarbon environments at ≤70 °C the morphological and mechanical properties of the PP polymer do not degrade significantly in a propane/propylene and iso-/n-butane environment.

“…Moreover, the membrane technologies are presently an established part of several industrial processes. The use of membranes to separate and recover products and by-products from process streams may increase the process efficiency [2,5,18,19]. The possibility of application of integrated membrane systems, especially the MD process combined with crystallization, created one of the new possibilities to solve the saline wastewater treatment [14][15][16][17].…”

Distillation is one of the oldest and most frequently used purification methods today. In 1813, Jean‐Baptiste Cellier‐Blumenthal patented the first continuously working distillation column, starting an impressive development of process equipment. New product areas were discovered as well as improved equipment installations. 100 years ago, Fritz Raschig patented his rings as packing material. Current developments are guided by deeper knowledge of heat and mass transfer as well as the integration of various process functions.
