    Abstract: The invention is directed to a multi-tier bypass apparatus for extending the operating life of fixed bed reactors. The multi-tier bypass may be disposed within a fixed catalyst bed to allow any fluid feedstock to bypass successive layers of the fixed catalyst bed as they foul. The invention also relates to an improved fixed bed reactor comprising the inventive multi-tier bypass and a method for extending the operating life of a fixed bed reactor.

    Abstract: A hydrocarbonaceous feed is hydroprocessed in a single vessel containing two reaction stages and a stripping stage. The feed is fed into the first reaction stage to produce a vapor and liquid effluent which are separated, and the liquid stripped. The stripped liquid is passed as feed into the second stage, in which it meets with fresh hydrogen to produce a hydroprocessed liquid product and a hydrogen-rich vapor. The vapor is passed into the first stage, to provide the hydrogen for that stage. The use of a single vessel provides an efficient and economical addition to, or replacement for, a vessel for an existing hydroprocessing facility.

    Abstract: A process for hydroprocessing liquid petroleum and chemical streams in two or more hydroprocessing stages, which stages are in separate reaction vessels and wherein each reaction stage contains a bed of hydroprocessing catalyst. The liquid product from the first reaction stage is sent to a stripping stage and stripped of H.sub.2 S, NH.sub.3 and other dissolved gases. The stripped product stream is then sent to the next downstream reaction stage, the product from which is also stripped of dissolved gases and sent to the next downstream reaction stage until the last reaction stage, the liquid product of which is stripped of dissolved gases and collected or passed on for further processing. The flow of treat gas is in a direction opposite the direction in which the reaction stages are staged for the flow of liquid. Each stripping stage is a separate stage, but all stages are contained in the same stripper vessel.

    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: Multi-control password changing includes initiating a password change cycle to change a target user's password, selecting a plurality of administrators to provide password part inputs, receiving password part inputs separately and confidentially from the plurality of administrators, generating a multi-control password comprised of multiple password part inputs, changing the target user's password to the multi-control password, and transmitting either the single multi-control password or multiple password parts each separately to target user. In an exemplary embodiment, a system for multi-control password changing includes a multi-control password changing module configured to change a target user's password, a recruitment module configured to select a plurality of administrators to provide password part inputs, a regulation module configured to receive and process password part inputs from the plurality of administrators, and a change value module configured to generate a multi-control password comprised of multiple password part inputs.

    Abstract: The present invention is a heat pipe having a specified volume of working fluid determined in relation to the interior volume of the heat pipe and a target temperature TT, to provide self-temperature regulation and pressure management. The heat pipe comprises at least a evaporator region and a condenser region having a known interior volume V and a mass of working fluid given by the relationship Mwf=Dwf at TT×V where Dwf is the density of the saturated vapor of the fluid at temperature TT plus an amount of additional working fluid sufficient to have the rate of evaporation about equal to the rate of condensation for the particular heat pipe configuration. The heat pipe has at least the condenser region having an interior coating of a hydrophobic material.
