Abstract: A solid product dispenser can be used to form a dilute liquid solution from a block of solid concentrate. In cases where only a small amount of liquid solution is needed, the solid product dispenser may dissolve the block of solid concentrate quickly and substantially uniformly to provide a solution of controlled concentration. This can be contrast with larger dispensing applications where a dispenser may dissolve a block of concentrate slowly at the start and more rapidly as the dispensing progresses, producing a solution with an average concentration higher than if only a small amount of solution were produced using the dispenser. In one example, the solid product dispenser includes a fluid distribution reservoir and a solid product reservoir positioned inside of the fluid distribution reservoir and over a platform on which the solid product sits. High pressure fluid flows between the two reservoirs, turbulently contacting the solid product.

Abstract: The invention provides methods and compositions for the protection of a membrane from both biofouling and from damage caused by a biocide. The invention utilizes PAA as both a biocide and as a reducing agent for other oxidizing biocides. This is especially beneficial because without the invention one would be forced to choose between preventing membrane biofouling or preventing membrane damage from oxidizing biocides.

Abstract: A method and apparatus for obtaining a solution from a solid product in contact with a liquid is provided. A solid product is housed within a dispenser. A liquid is introduced into contact with the solid product. The solution formed between the solid product and the liquid is collected, and a makeup liquid can be added thereto to further dilute or control the concentration of the formed solution. The amount of makeup liquid added to the solution can be controlled based on the temperature of the liquid to provide an automatic, continuously variable amount of liquid added to the solution. In addition, a method of providing a pressure independent control of the makeup liquid is also provided.

Abstract: The present invention generally relates to the use of diphenyliodonium salts for lowering sulfide concentrations and for preventing growth of microbes in a water injection system, a hydrocarbon extraction system, or a hydrocarbon production system. Treating oilfield injection and produced fluids containing high levels of microbes with diphenyliodonium salts can significantly decrease the amount of hydrogen sulfide produced, which can be used to measure sulfidogenesis. The treatment can also decrease the number of microbes in the injection and produced fluids. Thus, these diphenyliodonium salts can be effectively used as inhibitors of hydrogen sulfide generation and as biocides in oilfield fluids.
