  • Patent number: 6685824
    Abstract: Mercury is removed from crude oils, natural gas condensates and other liquid hydrocarbons by first removing colloidal mercury and solids that contain adsorbed mercury and then treating the hydrocarbons with an organic or inorganic compound containing at least one sulfur atom reactive with mercury. The sulfur compound reacts with dissolved mercury that contaminates the hydrocarbons to form mercury-containing particulates that are then removed from the hydrocarbons to produce a purified product having a reduced mercury content. Preferably, the treating agent is an organic sulfur-containing compound such as a dithiocarbamate or sulfurized isobutylene.
    Type: Grant

    Date of Patent: February 3, 2004

  • Patent number: 6117333
    Abstract: A process is disclosed which involves removing hydrocarbons, arsenic and mercury from wastewater produced in oil and gas fields. An oxidant, ferric ions, and flocculent are sequentially added to the wastewater to form a removable sludge containing the arsenic, hydrocarbon, and mercury contaminants. The Oxidation-Reduction Potential of the wastewater is controlled by oxidant addition to allow the required arsenic oxidation to occur while maintaining the mercury in elemental form. The process requires relatively short residence times between chemical additions and provides for large wastewater throughputs. The cleaned wastewater is suitable for discharge to the environment.

  • Patent number: 6058454
    Abstract: A method and system for autoconfiguring redundant arrays of memory storage devices contained within receptacles having one or more slots containing hardware sufficient to accept and electrically communicate with such memory storage devices. The capacities of the memory storage device receptacles for accepting memory storage devices are determined, and used to define an initial positioning of devices in at least one memory storage device receptacle. One or more asymmetrical groupings of memory storage devices is defined to permit an equation of electrically detected relative positions of the memory storage devices with actual physical positions within the receptacle. Thereafter, additional devices are added into the receptacles such that the ability to equate electrically detected relative positions of the devices with physical positions is preserved.

  • Patent number: 5071568
    Abstract: The ability of a waste treatment process to remove selenium from a waste stream is improved by pretreating the waste with a compound selected from the group having the formulaX(ZO.sub.a).sub.b,Q.sub.m O.sub.n,ClO.sub.3,Cl.sub.2 O.sub.6,Br.sub.3 O.sub.8,I.sub.2 O.sub.5, andmixtures thereof, wherein X is a cation, Z is halogen selected from the group consisting of chlorine, bromine, and iodine, a is an integer from 1-3, b is an integer equal to the valence of X, Q is chlorine or bromine, and m and n are each 1 or 2, provided than m+n equals 3.
