Abstract: A process for preparing nitric acid may involve vaporizing ammonia in at least one first ammonia vaporizer to produce an ammonia gas, oxidizing this ammonia gas to nitrogen dioxide in a plant section of a nitric acid plant, and absorbing the nitrogen dioxide in water to produce nitric acid. A residual gas containing nitrous gases may be taken off from the plant section of the nitric acid plant and conveyed to a residual-gas cleaning apparatus. The residual gas containing nitrous gases may be reduced by means of ammonia in the residual-gas cleaning apparatus, wherein ammonia-containing wastewater obtained in the at least one first ammonia vaporizer may be conveyed to the residual-gas cleaning apparatus. Such a process may eliminate or at least substantially reduce ammonia-containing wastewater. Furthermore, a plant can be used in this process for preparing nitric acid.

Abstract: Facilities are provided herein for authenticating a user to use a processing device. A user predefines authenticators of one or more types and associates these with graphical images. Upon on attempt to activate the processing device, a graphical image, of the graphical images, is selected for presentation to the user. The selected graphical image is presented to the user, who then provides input to authenticate with the device. A determination is made as to whether the user is authenticated to use the device. The determination is made based on input received from the user and based further on the authenticator associated with the selected graphical image. Varying the selection of image(s), each associated with a predefined authenticator and authentication type, enables variability in the authenticator that is suitable for unlocking a device at a given time, providing greater security to the authentication process.

Abstract: An apparatus and a process are described for preparation of nitric acid from ammonia and oxygenous gas by the single pressure or dual pressure process, in which the oxidation of the ammonia used is accomplished by means of compressed process air which has been compressed in at least one compressor over a catalyst, and the nitrous gas formed by the oxidation is at least partly absorbed by water, forming nitric acid, and the unabsorbed residual gas is expanded for the purpose of recovering compressor work in at least one multistage residual gas turbine (1).

Abstract: A process for sealing the NO compressor and the residual gas expander in a plant for the production of nitric acid by the dual-pressure process uses a low-pressure section, a NO compressor, a high-pressure section with oxidation and absorption, at least one heat exchanger, a residual gas expander, in which ammonia and compressed air are passed into the low-pressure section of the nitric acid plant, where ammonia is oxidised via a catalyst to yield NO and water. The obtained NO is partly oxidised to yield NO2. The NO- and NO2-saturated gas is passed into the NO compressor, the compressed NO- and NO2-saturated gas is passed into the high-pressure section of the nitric acid plant where the residual NO is oxidised to yield NO2, followed by absorption of nitrogen dioxide to nitric acid. The residual gas from the high-pressure section is routed to the residual gas expander via at least one heat exchanger.

Abstract: A method and apparatus for preventing rogue implementations of a security-sensitive class interface are provided. With the method and apparatus, a unique identifier (UID) is created by a server process when the server process is started. Anytime the server process, i.e. a server runtime environment, instantiates a new credential object following start-up of the server process, the encrypted UID is placed into a private field within the new credential object. In addition, the UID is encrypted and stored in a private class of the server runtime environment. A verification class is provided within the server runtime environment which includes one or more methods that receive the credential object as a parameter and return true or false as to the validity of the credential object.

Abstract: Objects on application servers are distributed to one or more application servers; a user is allowed to declare in a list which objects residing on each application server are to be protected; the list is read by an interceptor; responsive to exportation of a Common Object Request Broker Architecture (“CORBA”) compliant Interoperable Object Reference (“IOR”) for a listed object, the interceptor associates one or more application server security flags with interfaces to the listed objects by tagging components of the IOR with one or more security flags; and one or more security operations are performed by an application server according to the security flags tagged to the IOR when a client accesses an application server-stored object, the security operations including an operation besides establishing secure communications between the client process and the server-stored object.

Abstract: A system and method for tracking user security credentials in a distributed computing environment. The security credentials of an authenticated user includes not just his unique user identifier, but also a set of security attributes such as the time of authentication, the location where the user is authenticated (i.e., intranet user v. internet user), the authentication strength, and so on. The security attributes are used in access control decisions. The same user can be given different authorization if he has a different security attribute value. Security credentials may be generated either by WebSphere security code or by third party security provider code. This invention stores the user credentials in a distributed cache and provides a system and method to compute the unique key based on the dynamic security credentials for cache lookup.
