1 OBJECTIVE

The purpose of this document is to establish standards for flowsheet elaboration, from the content and drawing point of view

2 DEFINITIONS

2.1General Instructions

The flowsheets will be drawn in AUTOCAD, in the sheet format A1 or A1 multiple, according to the process sequence, from the left to the right whenever this is possible. The text height defined in the annex IV allow reduced plotting to A4 format height for easier handling when necessary.

The origin and destine of the flow lines will be indicated in the flowsheet ends by a standard block for each line, in which it will be indicated the number of the corresponding drawing.

In the flowsheet extremities, the complete media denomination will be written. For any other part, the standard media code shall be used.

The texts will be in Spanish or English, according to project definition, written in capital letters, except for units, that will be written in the usual form (e.g. gpm, l/min, etc.).

The progressive revisions shall be indicated by letters until approval for erection, when revision 0 (zero) will be established. From that on, revisions shall be indicated by numbers.

2.2Standard FormatAccording to annex I.

NOTES FOR TABLE1. A users choice letter is intended to cover unlisted meanings that will be used repetitively in a particular project. If used, the letter may have one meaning as a first-letter and another meaning as a succeeding-letter. The meanings need to be defined only once in a legend, or other place, for that project. For example, the letter N may be defined as modulus of elasticity as a first-letter and oscilloscope as a succeeding-letter.

2. The unclassified letter X is intended to cover unlisted meanings that will be used only once or used to a limited extent. If used, the letter may have any number of meanings as a first-letter and any number of meanings as a succeeding-letter. Except for its use with distinctive symbols, it is expected that the meaning will be defined outside a tagging bubble on a flow diagram. For example, XR-2 may be a stress recorder and XX-4 may be a stress oscilloscope.

3. The grammatical form of the succeeding-letter meanings may be modified as required. For example, indicate may be applied as indicator or indicating, transmit as transmitter or transmitting, etc.

4. Any first-letter, if used in combination with modifying letters D (differential), F (ratio), M (momentary), K (time rate of change, Q (integrate or totalize), or any combination of these is intended to represent a new and separate measured variable, and the combination is treated as a first-letter entity. Thus, instruments TDI and TI indicate two different variables, namely, differential-temperature and temperature. Modifying letters are used when applicable.

5. First letter A (analysis) covers all analysis not described by a users choice letter. It is expected that the type of analysis will be defined outside a tagging bubble.

6. Use of first-letter U for multivariable in lieu of a combination of first-letter is optional. It is recommended that nonspecific variable designators such as U be used sparingly.

7. The use of modifying terms high, low, middle or intermediate, and scan is optional.

8. The term safety applies to emergency protective final control elements only. Thus, a self-actuated valve that prevents operation of a fluid system at a higher-than-desired pressure by bleeding fluid from the system is a back-pressure-type PCV, even if the valve is not intended to be used normally. However, this valve is designated as a PSV if it is intended to protect against emergency conditions, i.e., conditions that are not expected to arise normally.

The designation PSV applies to all valves intended to protect against emergency pressure conditions regardless of whether the valve construction and mode of operation place them in the category of the safety valve, relief valve, or safety relief valve. A rupture disc is designated PSE.

9. The passive function G applies to instruments or devices that provide an uncalibrated view, such as sight glasses and television monitors.

10. Indicate normally applies to the readout analog or digital of an actual measurement. In the case of a manual loader, it may be used for the dial or setting indication, i.e., for the value of the initiating variable.

11. A pilot light that is part of an instrument loop should be designated by a first-letter followed by the succeeding-letter L. For example, a pilot light that indicates an expired time period should be tagged KQL. If it is desired to tag a pilot light that is not part of an instrument loop, the light is designated in the same way. For example, a running light for an electric motor may be tagged EL, assuming voltage to be the appropriate measured variable, or YL, assuming the operating status is being monitored. The unclassified variable X should be used only for applications, which are limited in extent.

The designation XL should not be used for motor running lights, as these are commonly numerous. It is permissible to use the users choice letter M, N or O for a motor running light when the meaning is previously defined. If M is used, it must be clear that the letter does not stand for the word motor, but for a monitored state.

12. Use of a succeeding-letter U for multifunction instead of a combination of other functional letters is optional. This nonspecific function designator should be used sparingly.

13. A device that connects, disconnects, or transfers one or more circuits may be either a switch, a relay, an ON-OFF controller, or a control valve, depending on the application.

If the device manipulates a fluid process stream and is not a hand-actuated ON-OFF block valve, it is designated as a control valve. It is incorrect to use the succeeding-letter CV for anything other than a self-actuated control valve. For all applications other than fluid process streams, the device is designated as follows:

A switch, if it is actuated by hand.

A switch, or an ON-OFF controller, if it is automatic and is the first such device in a loop. The term switch is generally used if the device is used for alarm, pilot light, selection, interlock, or safety.

The term controller is generally used if the device is used for normal operating control.

A relay, if it is automatic and is not the first such device in a loop, i.e., it is actuated by a switch or an ON-OFF controller.

14. It is expected that the functions associated with the use of succeeding-letter Y will be defined outside a bubble on a diagram when further definition is considered necessary. This definition need not be made when the function is self-evident, as for a solenoid valve in a fluid signal line.

15. The modifying terms high, and low, and middle or intermediate correspond to values of the measured variable, not to values of the signal, unless otherwise noted. For example, a high-level alarm derived from a reverse-acting level transmitter signal should be an LAH, even though the alarm is actuated when the signal falls to a low value. The terms, may be used in combination as appropriate. (See Section 6.9 of ISA standard).

16. The terms high and low, when applied to positions of valves and other open-close devices, are defined as follows: high denotes that the valve is in or approaching the fully open position, and low denotes that it is in or approaching the fully closed position.

17. The word record applies to any form of permanent storage of information that permits retrieval by any means.

18- For use of the term transmitter versus converter, see the definitions in Section 3.

19- First-letter V, vibration or mechanical analysis is intended to perform the duties in machinery monitoring that the letter A performs in more general analysis. Excepts for vibration, it is expected that the variable of interest will be defined outside the tagging bubble.

20- First-letter Y is intended for use when control or monitoring responses are event-driven as opposed to time-or time schedule-driven. The letter Y, in this position, can also signify presence or state.

21- Modifying-letter K, in combination with a first-letter such as L, T or W, signifies a time rate of change of the measured or initiating variable. The variable WKIC, for instance, may represent a rate-of-weight-loss controller.

22- Succeeding-letter K is a users option for designating a control station, while the succeeding-letter C is used for describing automatic or manual controllers. (See Section 3, Definitions of ISA standard).
