Abstract: A device is provided for increasing the pH of an acidic aqueous stream, which may result from commercial activity in petroleum, mining, metal finishing and food processing sectors, among others. A container defines an upright reactor portion with a cross-section that increases upwardly, along with inlet and outlet conduits connected to an inlet and an outlet between which the reactor portion is located. The conical portion contains a bed of substantially water-insoluble alkaline salt particulate, such as MgSO, the bed being such that, when the pH of the inflowing aqueous stream is below 7, contact between the particulate and the aqueous stream will raise the pH of the outflowing stream to a level above that of the inflowing stream.

Abstract: The present invention generally offers a system and a method that allows a vessel to treat water while providing corrosion inhibition. An oxygen stripping gas source produces oxygen stripping gas that may be pumped directly to, preferably but optionally, a venturi injector, or may first be pumped into an empty tank and then delivered to the injector means. Water being pumped through the injector via a transfer piping means comes into contact with the oxygen stripping gas, and dissolved oxygen in the water transfers to micro-fine stripping gas bubbles generated by the injector. The water and the micro-fine bubbles are pumped from the injector and into the tank, where the micro-fine bubbles float to the surface, and the oxygen is released into the tank's headspace. The deoxygenated water may be re-circulated through the system for additional deoxygenation or released from the tank into the surrounding waterways.

Abstract: A vapor recovery system for use during filling of a tank installation with a volatile liquid. The tank has a fill-pipe for the introduction of the liquid into the tank wherein the exit to which fill-pipe is normally below the liquid level in the tank. The vapor recovery system includes a reduced cross-sectional area region of the fill-pipe and a duct extending from that region through the side wall of the fill-pipe into the ullage space above the liquid level in the tank. The system further has a valve assembly associated with the duct which valve assembly normally closes off the duct, but which valve assembly is opened by flow of liquid along the fill-pipe into the tank, such that vapor in the tank may be drawn along the duct from the ullage space by the reduced static pressure in the region of reduced cross-sectional area of the fill-pipe. A method of recovering vapor using such a system is also described.

Abstract: The deaerator for liquid, comprises: a flow path in which the liquid flows; a pressure reducing deaerating device which removes dissolved gas contained in the liquid inside the flow path by reducing pressure of a deaerating section surrounding at least a portion of the flow path; and a variation device which varies a length of the flow path inside the deaerating section.

Abstract: An example system for processing a material stream includes a deoxygenator for removing dissolved oxygen. Removal of dissolved oxygen provides for the reduction of reactions and processes that can result in the generation of undesirable insoluble materials that can clog or otherwise foul the system. The deoxygenator includes an oxygen permeable membrane to remove dissolved oxygen from the flowing material stream. Because dissolved oxygen can be removed from the material stream essentially without disrupting flow, there is little affect on the overall process. The removal of dissolved oxygen provides significant increases in process efficiencies by reducing or eliminating the formation of undesirable by products within a material stream.

Abstract: An apparatus separates liquid, gas and solid components of a mixture in a fluid system. An inlet for receiving the mixture opens into a separation chamber tangentially with a cylindrical side wall and a gas outlet has an opening in a first end wall adjacent the inlet to allow gas to exit the separator. A fluid outlet is located in an opposing second end wall. A debris passage extends through the cylindrical side wall and oriented so that the radial velocity of the particles within the separation chamber directs the particles through the debris passage. The debris passage leads to a particle collection chamber in which the particles accumulate. Unlike prior separators that relied on the tangential velocity of the particles, the present apparatus utilizes the greater radial velocity to drive the particles from the separation chamber into the particle collection chamber.
