  • Publication number: 20030108473
    Abstract: Commercial grade ammonia is purified for use in production of semiconductors by initially passing the liquid ammonia through a liquid phase oil separation system. This removes the vast majority of the impurities. The filtered liquid ammonia is then passed through a vaporizer which quiescently forms ammonia vapor and prevents entrainment of impurities within the ammonia vapor. The vapor passes through a vapor filtration system and subsequently to a bubble column. The bubble column is designed so that the bubbles are small enough and travel at a rate which ensures that any entrapped particle within the bubble will have time to migrate to the surface of the bubble and thereby pass through the liquid phase. The collected vapor is directed through subsequent vapor filters and is collected. If anhydrous ammonia is desired, the ammonia vapor is collected upstream of the bubble column.

  • Publication number: 20030087769
    Abstract: A lubricant additive formulation for increasing the performance of conventional engine lubricants for use as an engine treatment oil additive formulated for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. A preferred embodiment of the engine treatment oil additive comprises a blend of chemical constituents including a base stock selected from a synthetic base stock, a mineral oil base stock, and a severly hydrocracked base stock or combinations thereof, an oil soluble molybdenum additive, dispersant inhibitor, and selected additives such as polytetrafluoroethylene, viscosity index improvers, and extreme pressure wear agent used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent or as a complete motor oil. Additional components may be added to the engine treatment oil additive formulation to enhance specific properties for special applications.

  • Patent number: 6559203
    Abstract: This invention relates to an organic foundry binder containing an alkyl resorcinol, or preferably a readily available mixture of alkyl resorcinols, and derivatives thereof. Preferably, the organic foundry binder is a furan binder. Foundry mixes are prepared by mixing the binder with a foundry aggregate. Foundry shapes (molds and cores) are prepared by shaping the mix and allowing it to cure to form a workable foundry shape. The invention also relates to the preparation of metal castings using the foundry shapes and the metal castings prepared with the foundry shapes.
