“…Until recently, the only glycol whose dehydration by PV studied in the laboratories was ethylene glycol (EG) (Feng and Huang, 1996;Guo et al, 2007;Du et al, 2008;Xu et al, 2010;Hu et al, 2012;Yu et al, 2012). However, two papers recently published reported results of DEG dehydration by PV (Akberov et al, 2014;Yim and Kong, 2013). In Yim and Kong (2013), PV dehydration was accomplished using hollow-fiber polymer membranes PVHFe085060BW of the SepraTek company (Incheon, Republic of Korea) having a selective layer made of a material based on polyvinyl alcohol (PVA), hereinafter referred to as SepraTek membranes.…”

“…The higher the saturation level is, the cheaper the natural gas dehydration at CGTP becomes due to energy savings on circulation and regeneration of DEG. In this regard, in Akberov et al (2014) an experimental study of PV dehydration of DEG by HybSi membranes was carried out for the DEG concentration ranges: 97e99.5 wt% and 93.5e99.5 wt% corresponding to saturation levels 2.5 wt% and 6.0 wt%, respectively. For convenience of reasoning, some results from Akberov et al (2014) in a somewhat changed form are given below for the DEG concentration range: 93.5e99.5 wt% (Figs.…”

The paper (Akberov et al, 2014) dealt with dehydration of DEG by PV using tubular ceramic membranes having a selective layer made of the HybSi material developed at Energy Research Center of the Netherlands (Castricum et al, 2008;van Veen et al, 2011), hereinafter referred to as HybSi membranes. In Yim and Kong (2013), results of experimental studies were obtained for DEG dehydration from 98 wt% to 99.5 wt%, whereas (Akberov et al, 2014) described results of experimental studies for DEG dehydration from 97 wt% to 99.5 wt% and from 93.5 wt% to 99.5 wt%.…”

In the present work, we consider some of the most important aspects of application of PV with the use of HybSi membranes for conditions present at CGTP, compare results of studies of PV dehydration using HybSi membranes with results of studies using SepraTek membranes and present advantages of the PV technology of DEG regeneration with HybSi membranes over the conventional stripping technology.…”

Increasing populations and urbanization put a lot of pressure on freshwater supplies and use. The increased demand for drinking water can be met by using seawater as a source of freshwater. Desalination and wastewater treatment have been energy-and time-consuming processes in recent years. Microbial desalination cells (MDCs) have gained considerable attention as an emerging technology because of their ability to treat wastewater, desalinate seawater, and produce electricity and value-added products. The efficiency and performance of this technology are affected by numerous factors. In this study, the effect of membranes on the efficiency and performance of this technology is examined. Anionic and cationic, carbon nanotube (CNT), bipolar and osmotic membranes were investigated. Anionic and cationic membranes, as well as their modifications, significantly influence microbial desalination cells.CNT-based membranes have shown significant improvements in water permeability, desalination capacity, strength, anti-fouling, and energy efficiency compared to other membranes. Bipolar membranes prevent the pH of the anode chamber from decreasing, which is essential for MDC operation. The use of FO membranes in microbial desalination cells still faces challenges; for instance, fouling is more likely in FO membranes than ion-exchange membranes, resulting in higher internal resistance and decreased water flux. MDC technology will require research into membrane fouling, electron transfer kinetics, material feasibility, microbial growth, and catalyst durability to be scaled and sustainable. As part of the feasibility study, the performance and stability of the reactor must also be examined.

Subsea processing enables broader exploration of oil and gas reservoir, giving an increased focus on developing alternative processes for subsea oil and gas treatment. This work provides a first evaluation of a new proposed subsea natural gas dehydration process with the use of a membrane contactor with triethylene glycol (TEG) for dehydration of the natural gas in combination with thermopervaporation for regeneration of the TEG. Simulation models are developed in Aspen HYSYS V8.6 and process optimization is performed on three different process designs with respect to staging of the regeneration. By introducing two thermopervaporation units in series the TEG flow rate is reduced by 55%, the membrane volume by 14.6% and the energy demands by 37.8%, compared to a design with one thermopervaporation unit. However, increasing the number of regeneration stages increases the complexity as additional heaters are introduced.
