    摘要: An ammonia purification system includes a hydrocarbon removal station that removes hydrocarbons from gaseous ammonia via adsorption, a moisture removal station that removes water from gaseous ammonia via adsorption, and a distillation station including a distillation column connected with a condenser to facilitate removal of impurities from ammonia and condensation of gaseous ammonia to form a purified liquid ammonia product. The system further includes a storage tank to receive purified ammonia, a remote station connected with the storage tank, and a vaporizer connected with the storage tank. The vaporizer is configured to receive and vaporize liquid ammonia from the storage tank and deliver gaseous ammonia back to the storage tank so as to facilitate pumping of the ammonia to the remote station based upon a vapor pressure established within the storage tank.

    摘要: Herein is disclosed a method and an apparatus for preparing a highly purified gas from a crude liquid comprising the gas and one or more of a metal, particulates, water vapor, or a volatile impurity. The method comprises: (a) vaporizing the crude liquid, to yield (i) a first vapor stream comprising the gas and (ii) a first liquid stream comprising the gas; (b) removing water vapor, particulates, or both from the first vapor stream, to yield a second vapor stream comprising the gas; (c) condensing the second vapor stream, to yield a second liquid stream comprising the gas; and (d) sparging the second liquid stream with an inert gas, to yield (i) a third vapor stream comprising the gas and (ii) a third liquid stream comprising the highly purified gas. Also disclosed is a method for preparing an adsorbent to effectively remove water vapor from the gas, as well as an adsorbent so prepared.

    摘要: A valve device that is securable to a cylinder includes a housing with a central passage in fluid communication with a first connection port that connects with a cylinder, and a second connection port including a passage that is in fluid communication with the central passage. The second connection port is configured to connect with a fluid flow line. A valve member is disposed within the second connection port and includes a movable member that engages with a seat to provide a fluid tight seal for the valve member in a closed position. The movable member is configured to be moved away from the seat so as to open the valve member and permit fluid to flow from the central passage of the valve housing around the movable member and through the second connection port while substantially preventing a backflow of fluids from a location external to the valve housing into the central passage.

    摘要: A valve member is secured within a valve device to facilitate flow of fluid from a cylinder to a fluid flow line. The valve member includes a hollow plug with a chamber, an inlet end and an outlet end, and an elastomeric sealing member disposed within the chamber. The sealing member includes lip portions that engage with each other to provide a fluid tight seal preventing fluid from flowing through the sealing member and hollow plug when a pressure at the outlet end of the hollow plug is greater than the pressure at the inlet end of the hollow plug. The lip portions are configured to flex away from each other to open the sealing member and permit fluid to flow through the hollow plug when a suitable pressure differential is established across the valve member and the pressure at the inlet end of the hollow plug is greater than the pressure at the outlet end of the hollow plug.

    摘要: A system and method for purifying liquefied corrosive gases of metallic impurities is described. The principle for this purification method relies on vapor-phase transfilling the vapor phase from a source container into a receiving container. This method has been observed to decrease metal concentrations by a factor of at least 1000 and, decreases the metallic impurity levels in the resulting condensate. The vapor transfer is accomplished by controlled differential pressure rather than mechanical pumping, thereby generating no particle or metal impurities.
