  • Patent number: 8992764
    Abstract: An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.

  • Publication number: 20150089018
    Abstract: A single centralized metadata repository for an entire enterprise can maintain the metadata pertaining to various different web service applications on application servers of heterogeneous types within the enterprise. The metadata items stored in the centralized repository all can be stored in a same canonical format that can be expected and understood by all metadata accessors. The metadata maintained within the central repository can be given a life span that is linked with the life span of the web service application to which that metadata pertains. When a web service application is deployed on an application server, metadata pertaining to that webservice can be pushed automatically to the central repository for storage. When such a web service application is undeployed from an application server, the metadata pertaining to that webservice can be removed automatically from the central repository so as not to waste storage space.
