An apparatus for removing oil, gas and by-products from pyrobituminous shale impregnated with hydrocarbons utilizes a vertically disposed reactor having a top portion, a middle portion and a bottom portion. As shale is introduced into the top portion of the reactor through a rotary seal mechanism, hot gasses are introduced into the middle portion of the reactor through hollow, parallel tubes having a hexagonal configuration with gas introducing holes disposed in the side walls which are protected by overhanging portions of the top walls. Relatively cool gasses are introduced into the bottom portion of the reactor through horizontally disposed circumferentially spaced pipes having downwardly and outwardly chamfered inner ends to prevent clogging of the pipes. The hot effluent gasses from the top portion of the reactor are passed through the cyclone, a heat regenerator for reducing the temperature of the gaseous stream and an electrostatic precipitator prior to being compressed. The compressed gaseous stream is divided into three parts with a first portion passing through a heater prior to being injected into the middle portion of the reactor. A second portion is passed through a heat regenerator prior to being introduced into the bottom portion of the reactor and the third portion of the compressed gaseous stream is passed through a heat regenerator and a cooler to a spray scrubbing tower. The liquid discharged from the spray scrubbing tower passes through first and second decanters with the watery discharge of the first decanter being recycled to the spray scrubbing tower.

The process for obtaining oil, gas and other products from pyrobituminous shales and the like includes introducing crushed shale into a retort and contacting the crushed shale in the top portion of the retort with a stream of retort gases. Hot gases are injected at an intermediate point of the retort and a stream of cold gases are injected at the bottom of the retort. The gaseous retorted matter above the zone where the shale undergoes pyrolysis is removed and directed to a cyclone from separation of heavy liquid components from a gaseous stream. The gaseous stream is then purified and compressed with a portion of the compressed stream being heated and reinjected as the steam of hot gases into the retort. The other portion of the compressed stream of gases is cooled and a liquid component consisting primarily of water and heavy oil is separate therefrom in a spray tower. The water portion is separated from the oil and recirculated to the spray tower while a part of the oily portion is separated for resue outside the process with the remainder being recycled to the cyclone. A portion of the compressed gases from the cyclone is cooled and injected into the bottom of the retort as the stream of cold gases.

An authorization system is described that includes a first interface, a processing system, and a second interface. The first interface is configured to receive an authorization instruction from an enterprise and receive an authorization request from a user device. The authorization instructions indicate authorization parameters. The user device transfers the authorization request each time the application is selected for execution. The authorization instructions are based on a license obtained by the enterprise for an application and wherein a user device operated by a user has the application. The processing system is configured to process the authorization request and authorization parameters to determine if the execution of the application is authorized. The second interface is configured to transfer an authorized message to the user device if the execution of the application is authorized and transfer an unauthorized message to the user device if the execution of the application is not authorized.
摘要:
A mechanism for the granulometric distribution of solid particles being loaded into a vessel of relatively large dimensions, such as a process reactor, blast furnace, silo, incinerator, dryer, etc., from equipment of small dimensions in relation to the vessel, includes a feed hopper which has an outlet opening that can be variably positioned within the mechanism to introduce the solid particles into a chamber located above the uppermost ends of a plurality of concentric, inclined, preferably conical or pyramidal surfaces. The latter define respective generally downwardly directed free flow paths for the particles to conduct them to a lower location where they enter the upper ends of a corresponding plurality of concentric sets of descending tubes. The discharge ends of the tubes where they feed into the vessel being charged are disposed in a symmetric array. The entire arrangement is such that, during the loading operation, the particles form a continuous bed of solids from the location where they accumulate in the space above the inclined plates to the location where they leave the descending tubes and accumulate in the vessel, so that the formation of "valleys" in the surface of the bed in the vessel and consequent segregation of the particles in the bed are effectively minimized.
