MEMBRANES  11 FEBRUARY 2014

 

20140211 KWR Watercycle Research Institute- Mr. Emile Corneslissen – Forward Osmosis for Separation, Concentration and Power Generation

KWR is investigating the possibilities of applying Osmosis for different purposes. The presentation covers an overview of 1) Forward Osmosis (=Osmosis), 2) the combination of Forward Osmosis with MBR and RO on lab and pilot scale to recover dissolved compounds from water recycle with reduced operational involvement, 3) the developments in membrane configurations to make FO feasible, 4) Sewer Mining, where FO enables higher biogas conversion and making pure water from sewage, 5) Concentrating oil & gas production and other waste streams. The second topic Pressure Retarded Osmosis enables the conversion of osmotic energy to electrical power using the difference in salt concentration between sea water and river water. PRO may in future enable the Osmotic desalination of seawater, reducing net power demand considerably. www.kwrwater.nl

 

20140211 Logisticon Water Treatment B.V. – Mr. Pieter van Staveren – New possibilities with SiC membranes

Logisticon is an independent Dutch SME, designing and constructing complete installations for drinking water, process water and wastewater from small to large capacities. Logisticon offers temporary and emergency units from its vast rental inventory.

Logisticon presented experience with commercial SiC UF and MF membranes for separating oily water emulsions and suspensions (on- and offshore) and other organic materials (BTEX, fatty acids) from water. Specific attention was given to an application on a high temperature, salty, high pH and aniline containing process stream. Tests were executed on lab scale and pilot integrated in the chemical process plant. It demonstrates SiC membrane performance being stable with the possibility to recover the organics for reuse. www.logisticon.com

 

20140211 HyET B.V. - Mr. Leonard Raymakers – Electro-chemical Hydrogen Purification

HyET develops and produces electrochemical membranes for the compression and purification of hydrogen. The principle consists of the split of H2 to H+ at the anode side of the membrane with subsequent association to H2 again on the cathode side of the membrane. The driving force is the electrons current that moves the protons from the anode to the cathode side. Applications are still pilot scale automotive and biogas. The membranes are strong and stable. HyET membrane compressors feature silence, compact, no lubrication, no water, low power consumption and one-step pressurization up to 800-1.000 bar. This makes possible fueling cars, fork-lifts, trucks and distributed as well as central green energy storage by on-site electrolysis hydrogen generation. The same process allows for separating hydrogen from gas mixtures to recover H2 from gasification of biomass or to purify H2. www.hyet.nl

 

20140211 Membrana – Mr. Paul Peterson & Mr. Jürgen Schneider - Gas Transfer in Liquids using Hydrophobic Microporous Membrane Contactors

Membrane is a multinational, part of the Polypore company, and has two main divisions Healthcare and Membrana Filtration covering Degasification, Gasification, Debubbling and Liquid Filtration. Membrana gave an overview of the different types of Liqui-Cel membrane contactors made from PTFE, PP and Polyolefine membranes and different housing materials, module build-up with hollow fibre arrays, baffled and non-baffled configurations and fat Micro-module. The system design was explained with performance data, illustrated with case studies. Applications are O2 from de-ionized water, CO2 removal to extend IX beds and improve EDI, degas to improve megasonic cleaning, N2 from N2 blanketed storage, VOC removal, humidification of gases, degassing or debubbling inks and photographic or coating emulsions, (de-)carbonation nitrogenation of beverages and off-shore injection water. Main message is that these membrane contactors reduce total cost in the conventional systems with a more sustainable operation. www.liqui-cel.com

 

20140211 ECN – Mr. Jaap Vente – Hybsi Membranes in processes, Status and Outlook

ECN Energy Research Centre of The Netherlands mission is to develop knowledge and technology, that enable a transition to a sustainable energy system. In the field of Energy Efficiency the Hybsi pervaporation membrane was developed and is commercialised by licensees Pervatech (NL) and CTI (F). The basic feature of Hybsi is the substitution of part of the silica oxygen by organic chains. This makes the membrane chemically and thermally resistant in a wide range of aggressive environments. ECN builds upon this feature in steering the selectivity for different gas-liquid mixtures (H2, N2, CO2, CO, CH4, He, H2O, organics), hydrophobicity and developing polymer supported hybrid silica membranes. www.hybsi.com

 

20140211 University Twente – Mrs. Kitty Nijmeijer – CapWa water recovery from fluegas: an update

At UT the Membrane Science and Technology group MST focuses at the Molecular Membrane Design to control mass transfer and the European Membrane Institute EMI is involved in the contract assistance in membranes varying from research to operational trouble shooting for industry. The CapWa technology enables to recover water from flue gases of power plants in sufficient volume to cover the BFW make-up demand by selectively capturing water vapour through SPEEK coated PES hollow fibre microporous membranes and subsequently as condensate after cooling. CapWa has now been tested in for 5.000 hours in the flue gas of a live power plant and in the dryer exhaust of a paper mill demonstrating that the membrane production method, the module configuration and the capture process perform. Recovered water EC is 100 respectively 10 μS/cm. www.utwente.nl/tnw/mtg

 

20140211 Pervatech – Mr. Frans Velterop – Pervaporation Systems and Applications

The Dutch SME Pervatech celebrates 15 years design, production and sales of pervaporation and vapor permeation membranes, modules and technology supported by application specific consultancy. Membranes are mainly ceramic based: Silica, Optimized Silica, Hybsi, Titania, and Zirconia supplemented by PDMS based polymer membranes for organophilic separations. Demonstrated applications are breaking azeotropes, water removal from organics (alcohols, A-protic solvents, DmAc, DMSO, DMF, Ethyl acetate, NMP, Phenol, Acetonitril, THF) and essential oils, separation of low molecular from high molecular solvents, in-situ dehydration of condensation reactions (trans-) esterification, acetylisation, ketalisation; isolation of aromas and flavours, VOC recovery, specific fermentor organics and wastewaters. DEMA direct ethanol from micro-algae. Examples of applications as singular units and as hybrid units in combination with conventional distillation. The most recently marketed product is the 1,2 m long multibore ceramic element reducing module size and cost. Financial feasibility figures of different applications were presented. www.pervatech.com
