A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.

摘要:
The present invention generally provides a roasting machine, which can roast both the food that needs to be rotated upon roasting and the food that does not need to be rotated while roasting. The roasting machine is provided with a housing for supporting and protecting a roasting cab and roasting pipes, a roasting plate for baking and heating various food which does not need to be rotated, roasting pipes for baking and heating various food which needs to be rotated continuously so that they can be uniformly heated, and a drive unit used to drive the roasting pipes to rotate. The roasting machine can be used to bake two kinds of food. As the roasting plate is removable, food which does not need to be rotated can be roasted when the roasting plate is placed over the roasting pipes, and the roasting pipes can be used to heat food which needs to be rotated so as to be heated, such as sausages when the roasting plate is removed.

The present invention is a rapid method of determining the concentration of the major components in a chemical stream. The present invention is also a simple, low cost, device of determining the in-situ concentration of the major components in a chemical stream. In particular, the present invention provides a useful method for simultaneously determining the concentrations of sodium hydroxide, sodium sulfide and sodium carbonate in aqueous kraft pulping liquors through use of an attenuated total reflectance (ATR) tunnel flow cell or optical probe capable of producing a ultraviolet absorbency spectrum over a wavelength of 190 to 300 nm. In addition, the present invention eliminates the need for manual sampling and dilution previously required to generate analyzable samples. The inventive method can be used in Kraft pulping operations to control white liquor causticizing efficiency, sulfate reduction efficiency in green liquor, oxidation efficiency for oxidized white liquor and the active and effective alkali charge to kraft pulping operations.
摘要:
The present invention discloses a mobile electron beam radiation sterilizing apparatus, comprising: a movable chassis vehicle (1); a cabinet body (2) installed on the chassis vehicle (1); an electron accelerator (6) which generates electron beam for articles to be radiation-processed; an accelerator control box (31), which controls operation of the accelerator, wherein the electron accelerator (6) is provided in the cabinet body. The invention has advantages as following: since the electron accelerator is provided in the cabinet body of the chassis vehicle, it has a small volume with flexible maneuverability, which can be transferred rapidly in a short time. In addition, the apparatus has no additional requirement of using environment, and does not need any additional construction. The invention can implement electron beam radiation for all kinds of documents and mails and achieve rapid and complete sterilization, reaching safety purpose. Further, there is no damage or residual radiation for the processed articles. Moreover, the apparatus has a high degree of automation assembly with easy operations and safety. Thus, it is suitable for chief departments at home and abroad.
