A block diagram is the simplest form of presentation. You are commenting using your Facebook account. If they are then shown on the flow-sheet, they are available for use by the specialist design groups responsible for the subsequent detailed design. Alterations and additions can be easily made.

FLOW-SHEET PRESENTATION – I
Physical property data, mean values for the stream, such as: The various types of flow-sheet are discussed below. Notify me of new posts via email. As the process flow-sheet is the definitive document on the process, the presentation must be clear, comprehensive, accurate and complete.
In another method each stream line is numbered and the data tabulated at the bottom of the sheet. On the detailed flow-sheets used for design and operation, the equipment is normally drawn in a stylised pictorial form. This is the method generally used by professional design offices.
The stream physical properties are best estimated by the process engineer responsible for the flow-sheet. It is best that each group use the same estimates, rather than each decide its own dun.

Notify me of new comments via email. Block diagrams are useful for representing a process in a simplified form in reports and textbooks, but have only a limited use as engineering documents. The stream flow-rates and compositions can be shown on the diagram adjacent to the stream lines, when only a small amount of information is to be shown, or tabulated separately. This is available in an English translation from the British Standards Institution.
With complex processes, their use is limited to showing the overall 280044.
For tender documents or company brochures, actual scale drawings of the equipment are sometimes used, but it is more usual to use a simplified representation. Fill in your details below or click an icon to log in: The simplest method, suitable for simple processes with few equipment pieces, is to tabulate the data in blocks alongside the 82004 stream lines.
Only a limited amount of information can be shown in this way, and it is difficult to make neat alterations or to add additional data. The data on the flow-rate of each individual component, on the total stream flow-rate, and the percentage composition, can be shown on the flow-sheet in various ways. To find out more, including how to control cookies, see here: The amount of information shown on a flow-sheet will depend on the custom and practice of the particular design office.
Each block can represent a single piece of equipment or a complete stage in the process. Stream temperature, degrees Celsius preferred. By continuing to use this website, you agree to their use.
The essential items must always be shown, the optional items add to the usefulness of the flow-sheet but are not always included.
