  • Patent number: 7790001
    Abstract: This invention relates to a process for reducing the corrosion rate of iron-containing vessels within an ethylene glycol distillation system. The inventive process includes the addition of an additive component of sodium nitrite and sodium hypophosphite into such iron-containing vessels, to thereby react with iron of the inside walls and form a protective coating thereon. This process reduces the corrosion rate in iron-containing vessels of the apparatus, and reduces the catalytic effects of iron corrosion products within the system. Thus, not only is the on-stream time of the vessels extended, but also product quality is improved by reducing the aldehyde content of the final ethylene glycol product.

    Abstract: An evaporation based method for generation of high pressure steam from produced water in the heavy oil production industry. De-oiled produced water is processed through a high pH/high pressure evaporator driven by a commercial watertube boiler. The vapor produced by the evaporator is suitable for the steam assisted gravity drainage (SAGD) method being utilized by heavy oil recovery installations, without the use of once through steam generators that require extensive chemical treatment, and without requiring atmospheric distillation, which requires high power consuming compressors. Evaporator blowdown may be further treated in a crystallizing evaporator to provide a zero liquid discharge (ZLD) system and, with most produced waters, at least 98% of the incoming produced water stream can be recovered in the form of high pressure steam.

  • Publication number: 20090178555
    Abstract: When water sprays into an empty tank or into the freeboard of filters, considerable flashing occurs to release about 50 to 80% of carbon dioxide, hydrogen sulfide, and other gases. The injection of air with the water enhances this degasification and produces a partial drained tank, in which it is required for the spraying or flashing to occur. When the water level reaches a low point, a switch signals for the vent to be opened and the air is stopped. But the inlet water continues to fill the tank and to displace the gasses through the vent. When the water reaches the vent, a high level switch closes the vent. Air injection starts again to repeat the cycle. Alternately, the injection of air with the influent water into a partially drained tank with a level controller and venting also effects this degasification.

Ammonia is then removed from the dechlorinated water before subjecting the water to distillation in a mechanical vapor compression distillation unit. A portion of the generated low-pressure-steam is used to sanitize the manufacturing equipment at certain prescribed locations, and the distilled water, exhibiting United States Pharmacopoeia purified water quality, is withdrawn from the still and stored as pharmaceutical water product. No reverse osmosis operation is required. A system for carrying out the process is also provided. Sanitization is carried out while the system is in a standby mode.

  • Patent number: 6733636
    Abstract: A method of treating produced water from heavy oil production to provide feedwater for the production of high quality steam. A produced water from heavy oil recovery operations is initially treated by first removing oil and grease to a desired level, preferably to about twenty parts per million, or less. The pH is then adjusted, normally downward and by acid addition, to release at least some carbonate alkalinity as free carbon dioxide. Preferably, all non-hydroxide alkalinity is removed, or substantially so, by introducing the feedwater into a decarbonator. In some cases, the pH may be raised (without, or subsequent to decarbonation, depending upon water chemistry) preferably by caustic addition, to maintain silica solubility in the feedwater.

  • Patent number: 6733637
    Abstract: A process for producing high purity isopropyl alcohol. In one embodiment, the process includes the steps of: (a) feeding a feed stream comprising at least about 99.9 wt. % isopropyl alcohol into a separation column; (b) separating the isopropyl alcohol into an overhead stream taken overhead from the separation column and a bottoms stream taken as bottoms from the separation column; and (c) removing the high purity isopropyl alcohol at a point: (i) below where the feed stream enters the separation column but above the bottoms stream, or (ii) above where the feed stream enters the separation column but below the overhead stream. The high purity isopropyl alcohol has a metals content of less than about 1 ppb and a water content of less than about 100 ppm.

  • Patent number: 6716344
    Abstract: A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.
