Equipment Specification Data Sheets

Design (EEED) diagrams, equipment data/specification sheets etc. Prepare plot, equipment and pipe layout drawings Request quotations for equipment, construction, instrumentation, electrical work etc. Prepare drawings of control room, shelter, plant lighting etc. Design fire-fighting system... 

In order to establish the initial inquiry, a specification sheet similar to Figure 12-57 can be used. API Standard 617 also has a comprehensive data form and excellent performance and mechanical standards. In general all of the information on these sheets need not be given to the manufacturer, just the basic performance data and known specifications. The manufacturer is expected to complete the information as it applies to his equipment. A summary of the essential information is as follows ... 

There are also two notable research institutes offering information that may assist the engineer in making out the specification sheets. One of these is the Heat Transfer Research Institute (HTRI). Its staff performs tests to optimize the design of heat-transfer equipment. This information is then encoded in computer programs, which are distributed to the companies that support the research. This means that the engineer s company must purchase a membership to obtain these data. The Fractionation Research Institute (FRI) is a similar institution that deals with the separation processes.

As defined in Subsect. 2.1.2, a document is an aggregation of data and acts as a carrier of product data in a certain work context. One possibility to represent models of document contents is the use of the extensible Markup Language (XML) [1060] and its Document Type Definitions (DTDs), as suggested by Bayer and Marquardt [19]. Within a DTD, the structure of a specific document type can be described. Figure 2.9 shows the (incomplete) DTD of a specification sheet for vessels. Here, the different data items like temperature or construction material are indicated to specify the piece of equipment. However, the expressiveness of such document type definitions is rather restricted. A DTD specifies only the syntax of the document content but not its semantics. One possibility to enrich the DTD with meaning is to relate the single DTD elements to the classes and attributes of a product data model. This is exemplarily shown Fig. 2.9, where relations between some DTD elements and the corresponding classes of the product data model CLiP (cf. Subsect. 2.2.3) are indicated. 

There are two ways in which the correct implementation of design specifications can be checked. The PSSR team members can carry out spot checks of the installed piping and equipment, and compare it with the piping lists and equipment data sheets. The second way is to make sure that a system of turnover packages (which are discussed below) has been implemented and followed. 

Engineering information in the form of equipment data sheets, instruments specifications, and maintenance instructions provide a necessary background to the operating instructions. 

As process equipment data sheets become available, equipment specifications and procurement documents are written, enquiries are issued, and equipment is selected and purchased. 

Process engineer will update all the equipment data sheets (such as vessels, heat exchangers, fire healers, pumps, compressors, filters, etc.) and give them to the engineer responsible for this eqinpment. The equipment engineer will add more information to the data sheets according to project equipment specification and his/her comments, and send them to vendors for bid. 

Occupational Safety and Health. OSHA has set no specific limits for sodium and potassium sibcates (88). A pmdent industrial exposure standard could range from the permissible exposure limit (PEL) for inert or nuisance particulates to the PEL for sodium hydroxide, depending on the rate of dissolution and the concentration of airborne material. Material safety data sheets issued by siUcate producers should be consulted for specific handling precautions, recommended personal protective equipment, and other important safety information. 

Data on spare and parallel equipment are often omitted. Valving is also generally omitted. A alve is shown only where its specification can aid in understanding intermittent or alternate flows. Instrumentation is indicated to show the location of variables being controlled and the location of the actuating device, usually a control valve. To help the reader better understand the process flow sheet, a list of commonly used symbols is presented in Fig. 5.9.1. 

Used to present the heat and material balance of a process. This may be in broad block form with specific key points delineated, or in more detailed form identifying essentially every flow, temperature and pressure for each basic piece of process equipment or processing step. This may and usually does include auxiliary services to the process, such as steam, water, air, fuel gas, refrigeration, circulating oil, etc. This type of sheet is not necessarily distributed to the same groups as would receive and need the piping flowsheet described next, because it may contain detailed confidential process data. 

For some purposes the addition of equipment specification and performance data on the flowsheets adjacent to the item is of value. In many cases though, this additional information makes the sheets difficult to read. The... 

The first step in establishing a database that defines the operating condition of each machine-train or production system is to generate an equipment information sheet (EIS) for each machine-train. The information sheet must contain all of the machine-specific data such as type of operation and information on all of the components that make up the machine-train.
