摘要:
A process for the regeneration of sulfuric acid contaminated with hydrocarbons and water to produce pure concentration acid comprising: contacting sulfuric acid contaminated with hydrocarbons and water with oxygen and elemental sulfur in the presence of a vanadium containing catalyst in a reaction zone, maintaining at least a portion of the acid in the liquid phase, converting hydrocarbon to carbon oxides and water, and converting sulfur and sulfurdioxide to sulfurtrioxide, (4) separating the reactor effluent into a vapor stream and a liquid stream and cooling and partially condensing of the vapor stream to concentrate clean acid.

The present invention is directed to a method of asset location. Location data is received from a cellular transmitter associated with a selected asset, which location data includes data representative of a cellular receiver with which direct communication with the cellular transmitter is made. The location data is then communicated to a tracking service system, which tracking service system includes a database representative of geographic locations associated with a plurality of cellular receivers. The database is then queried with received location data so as to generate geographic tracking data associated with a location of the cellular receiver, the geographic tracking data including display data adapted to generate a map image including a representative of a location of the selected asset. The geographic tracking data is then communicated to an associated security agency so as to allow for viewing of an image generated in accordance with the display data and at least one of tracking and interception of the selected asset.
摘要:
A process for the removal of organic sulfur compounds, primarily oxygenated organic compounds, such as sulfates and sulfonic esters from a hydrocarbon liquid is disclosed which comprises contacting the hydrocarbon liquid with a coalescer comprising a mesh material which has been wetted by sulfuric acid. The hydrocarbon liquid may be the product from a sulfuric acid catalyzed alkylation process and contain sufficient sulfuric acid to remove the sulfates and sulfonic esters. Sulfuric acid may be added to the coalescer vessel counter current to the hydrocarbon liquid to improve the efficiency of the contacting and removal.
摘要:
A method, apparatus and computer program product for performing dynamic Voice Over Internet Protocol (VOIP) endpoint mapping is presented. At least one on net endpoint of a VOIP call is determined. An endpoint data structure is used to store, for each on net endpoint of the call, a key and at least one of an Internet Protocol (IP) address of the end point, a phone number associated with the endpoint, and/or a display name associated with the endpoint. The endpoint data structure is used to correlate call legs across a network. Heuristics of the VOIP call are determined, the heuristics including information relating to the main source call leg and the main destination call leg.

A method includes, receiving a unit of information, wherein the unit of information pertains to an architectural structure or a vehicle. The unit of information is stored local to a user and the user is notified wirelessly, based on the unit of information. An apparatus includes a storage device configured to receive a unit of information that is associated with the architectural structure or the vehicle. A processor is programmed to receive the unit of information, maintain the unit of information in the storage device, and initiate a notification to the user in response to the unit of information, wherein the notification is communicated wirelessly to the user.
摘要:
Bubble columns fractionate with vapor-liquid mass transfer efficiencies approaching that of distillation towers when vapor velocities in excess of 50% of jet flood are used. If the vapor velocities are pushed above about 70% of jet flood then the distillation performance of a given column packing becomes similar for both liquid continuous operation (bubble column mode) and vapor continuous operation (ordinary distillation tower mode).
摘要:
Acetylenes and dienes in a stream containing hydrogen, methane, C2-C6 olefins and paraffins, C2-C6 acetylenes and dienes, benzene, toluene, xylenes, and other C6+ components are hydrogenated in a downflow boiling point reactor wherein the heat of reaction is absorbed by the liquid in the reactor which produces a vapor. Besides the feed to the reactor there is a recirculating stream which is fed at a rate sufficient to ensure that the catalyst particles within the reactor are wetted. A third stream, which is taken from a downstream distillation column, is fed to provide the make up mass corresponding to the mass evaporated in the reactor. The composition of the this third stream controls the steady state composition of the liquid flowing through the reactor.

A sealing reducing washer is formed from a metallic reducing washer having a front surface, a rear surface, an outer periphery, and an inner periphery with a pliable rim secured over the outer periphery of the metallic reducing washer, a portion of the rim circumferentially depending below the rear surface of the metallic reducing washer adjacent the outer periphery of the metallic reducing washer so as to form a weathertight seal against a surface of an electrical enclosure when the sealing reducing washer is secured to the enclosure, and a pliable toroid circumferentially positioned adjacent the inner periphery of the metallic reducing washer and extending circumferentially above the front surface of the metallic reducing washer in the region adjacent the inner periphery of the metallic reducing washer, the toroid dimensioned to form a weathertight seal with an electrical conduit or raceway.
摘要:
The plow lock is a device that is adapted for use with a plow or a snowplow in order to immobilize the plow or snowplow from use. The plow lock includes a first plate affixed to a second plate. The second plate forms a right angle with the first plate. The first plate includes a first lock hole thereon. The second plate is further defined with an outer surface. The outer surface of the second plate is affixed to a wedge member. The wedge member extends outwardly from the second plate. The plow attachment bracket includes a plow lock hole that aligns with the first lock hole of the first plate such that a lock is locked thereon so as to secure the plow lock onto the plow attachment bracket thereby preventing a vehicle from attachment to the plow attachment bracket.
