In another method each stream line is numbered and the data tabulated at the bottom of the sheet. You are commenting using your Facebook account. Notify me of new posts via email. The simplest method, suitable for simple processes with few equipment pieces, is to tabulate the data in blocks alongside the process stream 2804.

To find out more, including how to control cookies, see here: Alterations and additions can be easily made. As the process flow-sheet is the definitive document on the process, the presentation must be clear, comprehensive, accurate and complete.
Stream temperature, degrees Celsius preferred. Fill in your details below or click an icon to log in: 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.
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. The essential items must always be shown, the optional items add to the 228004 of the flow-sheet but are not always included.
A block diagram is the simplest form of presentation.

Email Address never made public. On the detailed flow-sheets used for design and operation, the equipment is normally drawn in a stylised pictorial form. The amount of information shown on a flow-sheet will depend on the custom and practice of the particular design office.
Physical property data, mean values for the stream, such as: 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. Block diagrams are useful for representing a process in a simplified form in reports and textbooks, but dij only a limited use as engineering documents. Notify me of new comments via email. It is best that each group use the same estimates, rather than each decide its own values.

This is available in an English translation from the British Standards Institution.
The various types of flow-sheet are discussed below. This is the method generally used by professional design offices. You are commenting using your Twitter account.
With complex processes, their use is limited to showing the overall process. You are commenting using your WordPress.
For tender documents or company brochures, actual scale drawings of the equipment are sometimes used, but it is more 28040 to use a simplified representation. Each block can represent a single piece of equipment or a complete stage in the process.
The stream physical properties are best estimated by the process engineer responsible for the flow-sheet. The blocks can be of any shape, but it is usually convenient to use a mixture of squares and circles, drawn with a template.
