    摘要: The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature may be combined with a process of ceramic ultra-filtration (UF filtration) employed to treat water, and optionally followed by any of membrane distillation or forward osmosis (FO). Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.

    摘要: A mixed matrix membrane for separating gas components from a mixture of gas components is disclosed. The membrane comprises a continuous phase polymer with inorganic porous particles, preferably molecular sieves, interspersed in the polymer. The polymer has a CO2/CH4 selectivity of at least 20 and the porous particles have a mesoporosity of at least 0.1 cc STP/g. The mixed matrix membrane exhibits an increase in permeability of least 30% with any decrease in selectivity being no more than 10% relative to a membrane made of the neat polymer. The porous particles may include, but are not limited to, molecular sieves such as CVX-7 and SSZ-13, and/or other molecular sieves having the required mesoporosity. A method for making the mixed matrix membrane is also described. Further, a method is disclosed for separating gas components from a mixture of gas components using the mixed matrix membrane with mesoporous particles.

    摘要: A mixed matrix membrane is provided which comprises a continuous phase organic polymer and small pore molecular sieves dispersed therein. The molecular sieves have a largest minor crystallographic free diameter of 3.6 Angstroms or less. When these molecular sieves are properly interspersed with a continuous phase polymer, the membrane will exhibit a mixed matrix membrane effect, i.e., a selectivity increase of at least 10% relative to a neat membrane containing no molecular sieves. Finally, methods for making and using such mixed matrix membranes to separate gases from a mixture containing two or more gases are also disclosed.

    摘要: A mixed matrix membrane is provided which comprises a continuous phase organic polymer and small pore alumina containing molecular sieves dispersed therein. The molecular sieves have a silica-to-alumina molar ratio of less than 1.0, more preferably, less than 0.3, and most preferably less than 0.1. In some cases, the molecular sieves have no appreciable amounts of silica. Exemplary compositions include aluminophosphates (AIPO) and silicoaluminophosphates (SAPO). When these molecular sieves are properly interspersed with a continuous phase polymer, the membrane will exhibit a mixed matrix membrane effect, i.e., a selectivity increase of at least 10% relative to a neat membrane containing no molecular sieves. The molecular sieves have pores with a largest minor crystallographic free diameter of 4.0 Angstroms or less. The molecular sieves may be selected from the group having IZA structure types including AEI, CHA, ERI, LEV, AFX, AFT, and GIS. Examples of preferred molecular sieves include: AIPO-18, SAPO-18, AIPO-34, SAPO-34, SAPO-44, SAPO-47, AIPO-17, SAPO-17, CVX-7, SAPO-35, SAPO-56, ALPO-52, and SAPO-43. Finally, methods for making and using such mixed matrix membranes to separate gases from a mixture containing two or more gases are also disclosed.
