摘要： A multi-layer membrane which has a mixed polyamide selective layer supported on a porous polysulfone layer. The mixed polyamide selective layer includes reacted units of a polyfunctional acyl halide (e.g. trimesoyl chloride) and a diamine mixture containing 4,7,10-trioxa-1,13-tridecanediamine and a cyclic diamine (e.g. piperazine). Methods of fabricating the multi-layer membrane via techniques such as phase inversion and interfacial polymerization are described. The inventive membrane is evaluated on its water flux and salt rejection (e.g. sulfate and chloride salts) capabilities. A water desalination system containing the multi-layer membrane(s) is also provided.

摘要： A method for concentration of oligonucleotides from a solution comprising negatively charged oligonucleotides is provided. The method includes the steps of: circulating the solution through an ultrafiltration or nanofiltration unit having a membrane, filtering the solution through the membrane to remove salts from the solution and obtain a retentate solution including the oligonucleotides and a permeate solution including the removed salts, diafiltering the retentate solution with a diafiltration buffer to produce a concentrated oligonucleotide solution, and collecting the concentrated oligonucleotide solution. The membrane has a nominal molecular weight cutoff in the range of from about 700 to about 5000 daltons, a negatively charged surface with a zeta potential of −20 mV or lower, and a water flux in the range of 800 to 1500 ml/min/m2.

摘要： A method and system for the offshore production of fuel includes an offshore marine platform on which is mounted an ammonia production unit. The ammonia production unit may produce ammonia utilizing raw materials sourced adjacent the marine platform, including seawater and electricity from offshore wind turbines. The produced ammonia may be subsequently liquified and transported away from the marine platform, or conveyed to a remote location via a seabed pipeline. A portion of the hydrogen produced as part of the ammonia production process may be utilized to operate onboard combustion turbines that can in turn drive electric generators onboard the marine platform to produce electricity.

摘要： Various embodiments of a system and method for enriching a concentration of components of interest in an air flow are described. The system includes an apparatus for enriching a concentration of components of interest in an air flow. The apparatus includes a chamber and a tube having a tube wall made of a selectively permeable material positioned within the chamber. A first end of the tube is connected to the inlet port of the chamber and a second end of the tube is connected to the outlet port of the chamber. The selectively permeable material has a lower permeability to components of interest than to inert gases, and the selectively permeable material is non-reactive with components of interest. The apparatus is configured to receive a sample stream and the chamber is maintained at a chamber pressure that is different than a stream pressure of the sample stream.

摘要： A continuous process for making polyolefines are disclosed. The process involves a membrane-assisted separation of non-reacted olefins downstream a polymerisation reactor and enables economical production of polyolefines from non-polymer grade olefin monomers. Uses of membranes adapted to such processes are also disclosed. And, further disclosed are membranes, membrane modules, and separation units adapted to such process as well as polymerisation plants comprising such membrane separation units.
