    Abstract: A process for hydroprocessing middle distillate petroleum streams in two temperature stages. The feedstream is hydroprocessed in two or more first temperature stages operated at a temperature from about 360.degree. C. to about 450.degree. C. The reaction product of the first temperature stage(s) is quenched to a temperature from about 260.degree. C. to about 350, stripped of H.sub.2 S, NH.sub.3 and other dissolved gases, then sent to the second temperature stage which is operated at said quenched temperature range. The product from the second temperature stage is also stripped of dissolved gases. Color bodies produced in the higher temperature first stage are hydrogenated in the last stage.

    Abstract: The invention is for a fixed bed reactor with two phase gas and liquid flow. The reactor has at least one auxiliary bed of solid particles disposed above the main bed of solid particles. The auxiliary bed has separate liquid and gas bypasses comprised of hollow tubing extending through the auxiliary bed. Liquid receptacles provide a liquid seal above the liquid bypasses, thereby preventing gas from bypassing along with the liquid. The liquid spilled from the flow receptacles seeks its lowest level and flows through the auxiliary bed, thereby leaving only the gas to flow through the gas bypasses. This separate feed arrangement allows for a low pressure drop bypassing of the auxiliary bed, when the auxiliary bed becomes fouled and clogged. The invention is also applicable to other apparatuses which use a flow arrangement similar to fixed bed reactors, but which do not necessarily utilize a chemical reaction. One example of such apparatus is a packed absorption tower having co-current downflow of gas and liquid.

    Abstract translation: 本发明是用于具有两相气体和液体流的固定床反应器。 反应器具有至少一个固体颗粒辅助床，其设置在固体颗粒主床上方。 辅助床具有分开的液体和气体旁路，包括延伸穿过辅助床的中空管。 液体容器在液体旁路之上提供液体密封，从而防止气体与液体一起旁路。 从流动容器溢出的液体寻求其最低水平并流过辅助床，从而仅使气体流过气体旁路。 当辅助床被弄脏并堵塞时，这种单独的进料布置允许辅助床的低压降旁路。 本发明也适用于使用类似于固定床反应器但不一定利用化学反应的流动布置的其它装置。 这种装置的一个实例是具有气流和液体的并流下流的填充吸收塔。

    Abstract: Embodiments described herein generally relate to creating an autonomous role-based security system for a database management system, wherein a super user may not always be required. A computer-implemented method is described. The method includes establishing one or more privileges in a database system, each privilege controlling access to an administrative function for the database system. Each privilege is assigned to one or more roles. Each role may always have a minimum set of users with only administrative rights over the role. A request is received from a first user to grant a role to a second user. A database management system determines whether the first user has administrative privileges over the role. If the first user has administrative privileges over the role, the role is granted to the second user. The database system may satisfy the principles of least privilege and separation of duties.

    Abstract: A method and system for drilling a wellbore is described. The system includes a wellbore with a variable density drilling mud, drilling pipe, a bottom hole assembly disposed in the wellbore and a drilling mud processing unit in fluid communication with the wellbore. The variable density drilling mud has compressible particles and drilling fluid. The bottom hole assembly is coupled to the drilling pipe, while the drilling mud processing unit is configured to separate the compressible particles from the variable density drilling mud. The compressible particles in this embodiment may include compressible hollow objects filled with pressurized gas and configured to maintain the mud weight between the fracture pressure gradient and the pore pressure gradient. In addition, the system and method may also manage the use of compressible particles having different characteristics, such as size, during the drilling operations.

    Abstract: A method and system are provided for developing images for use in a graphical user interface. In one implementation, the method includes displaying a graphical user interface on a display device, and providing an operating system on a computer that is in communication with the display device. The operating system includes an imaging object structure that is an abstract base class from which subclasses of text imaging objects, picture imaging objects, and pattern imaging objects are derivable. The subclasses of text imaging objects, picture imaging objects, and pattern imaging objects are used to respectively generate text imaging objects, picture imaging objects, and pattern imaging objects for display in the graphical user interface.
