摘要： Described is a method for concentration and extraction of gas field chemicals. The method includes collecting produced water from a gas oil separation plant, treating the produced water to remove oil, and receiving a feed solution containing a gas field chemical and water. The treated produced water is used as a draw solution to concentrate and absorb water from the feed solution using a forward osmosis chamber. A concentrated feed solution containing the gas field chemical and a diluted draw solution is produced. The concentrated feed solution is extracted and stored for injection into gas wells.

摘要： A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. In one embodiment, dynamic filtration is used for the separation of the heavy oil from the catalyst particles. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst.

摘要： The wet-processing apparatus includes a wet-step bath in which a wet-step is carried out, and a vibration-type film separator for separating impurities out of a solution used in the wet-step. The wet-processing apparatus further includes a re-supply path through which the solution out of which the impurities were removed by means of the vibration-type film separator is re-supplied to the wet-step bath. Thus, it is possible to reuse a solution and a material of which a pattern is composed. Since the vibration-type film separator is used, it is possible to reduce a frequency of exchanging filters equipped in the vibration-type film separator, and ensure a high rate at which a material of which a pattern is composed is recovered, regardless of a specific gravity of the material.

摘要： Process for treating an aqueous particle dispersion containing water-insoluble polymer particles and a water-soluble dispersant, the concentration of dispersant in water being less than that of the polymer particles. The process comprises subjecting the aqueous particle dispersion to solid particle filtration and then subjecting the resulting substantially particle-free aqueous solution to membrane filtration to obtain a permeate stream of substantially purified water and a retentate stream having an increased dispersant concentration. The permeate stream can be reused and/or recycled as wash water during the solid particle filtration. The retentate stream can be recycled as aqueous dispersant for size reducing the water-insoluble polymer particles at a temperature at or above the softening point of the polymer.

摘要： The current invention provides improved methods and filter stacks for concentrating a slurry of titanium dioxide. The improved filter stack comprises a series of filter disks and diverter trays arranged in parallel. The present invention provides an improvement over prior art filter stacks by using a substantially complete weld to attach a diverter plate to the diverter trays. The current invention also provides an improved method for pre-conditioning a filter stack. The improved method is designed to pre-condition and gradually prepare the filter stack for production of the desired slurry of titanium dioxide. Further, the current invention provides an improved process for preparing and transporting a slurry of titanium dioxide. Finally, the current invention provides a method for enhancing the lifespan of a filter stack. The method for enhancing the lifespan of the filter stack continuously monitors the flow rate and specific gravity of fluids produced from the filter stack and signals the need for flushing of the filter stack.

摘要： A filtering element has ultrafiltration or microfiltration hollow fiber membranes extending horizontally between a pair of opposed horizontally spaced, vertically extending headers. Side plates extending between the pair of vertically extending headers define a vertical flow channel through the element. Modules are created by placing the elements in place without obstructing the vertical flow channels. Each element may be released from the frame, however, and removed by sliding it in a direction substantially normal to its headers without disassembling the remainder of the module. The elements have associated releasable water tight fittings between the elements and a permeate collector, the releasable water tight fittings being releasable by removing an element from the frame. An aerator below the module has a plurality of air holes located to provide a line of air holes below each element or below a side plate between each pair of elements. In a preferred process, permeate flux is less than 50 L/m2/h and preferably less than 35 L/m2/h, aeration to scrub the membranes is provided during periods of time when permeation is periodically stopped and accumulated solids are removed by periodically emptying and refilling a tank containing the elements. A bubble point test is applied to each row of the module in turn, the presence of bubbles in a particular flow channel indicating which, if any, elements of a row are suitable.
