摘要： The invention relates to a method for processing asphaltene-containing feed to a pyrolysis furnace by raising the final boiling point of the feed/steam mixture to the pyrolysis furnace to ensure fouling occurs lower in the convection section where the mixture of air and steam can burn off fouling deposits during decoking operations. The final boiling point of the feed stream is increased by adding a heavy essentially asphaltene-free high boiling point hydrocarbon to the feed stream before the feed stream enters the convection section of the pyrolysis furnace, whereby said fouling occurs lower in the convection section.
摘要翻译：本发明涉及通过将进料/蒸汽混合物的最终沸点提高到热解炉来将沥青质的进料加工成热解炉的方法，以确保在空气和蒸汽的混合物可以燃烧的对流部分中发生较低的结垢在除焦作业期间污染沉积物。在进料流进入热解炉的对流段之前，通过向进料流中加入重质基本上不含沥青质的高沸点烃来提高进料流的最终沸点，由此在对流段中发生较低的污垢。

摘要： A feedstream comprising tar is feed to a solvent deasphalter wherein it is contacted with a deasphalting solvent or fluid to produce a composition comprising a mixture or slurry of solvent containing a soluble portion of the tar, and a heavy tar fraction comprising the insoluble portion of the tar. These fractions may be separated in the deasphalter apparatus, such as by gravity settling wherein the heavy tar fraction is taken off as bottoms, and the solvent-soluble fraction taken as overflow or overheads with the solvent. The overflow or overheads is sent to a solvent recovery unit, such as a distillation apparatus, wherein solvent is recovered as overheads and a deasphalted tar fraction is taken off as a sidestream or bottoms. The solvent or a portion thereof, recovered as overheads, may be then be recycled to the solvent deasphalter, or in a preferred embodiment, at least a portion of the solvent is steam cracked to produce a product comprising light olefins.

摘要： Techniques used in a relational database system for defining subclasses of built-in classes and thereby achieving columns in database tables which contain polymorphic objects of the built-in classes. The methods for the subclasses are contained in named packages. A table in the database system's schema relates the package name to a storage location managed by the relational database system that contains the compiled code for the package. When a method from the package is invoked, a dynamic linker uses the name and the table to locate the compiled code and then executes the compiled code. One thing that can be done with subclasses is to use a database system to automatically connect a Web user with a server of streaming data. The connection thus established is made by the server of streaming data to the Web user and thus bypasses the database system.
摘要翻译：在关系数据库系统中使用的技术，用于定义内置类的子类，从而实现包含内置类的多态对象的数据库表中的列。子类的方法包含在命名的包中。数据库系统架构中的表将包名称与关系数据库系统管理的存储位置相关联，该存储位置包含该包的编译代码。当调用来自包的方法时，动态链接器使用名称和表来定位编译的代码，然后执行编译的代码。可以用子类完成的一件事是使用数据库系统来自动连接Web用户与流数据的服务器。由此建立的连接由流数据服务器发送给Web用户，从而绕过数据库系统。

摘要： A waveform generator for providing an analog output signal to a target device includes a look-up-table (LUT) that stores a plurality of binary address values and a digital-to-analog converter (DAC) that generates the analog output signal. The waveform generator receives an input trigger signal from the target device when the target device is ready to receive the analog output signal. The waveform generator generates a synchronized input trigger signal and aligns the analog output signal with the synchronized input trigger signal by reloading the LUT with a binary address value of zero.
