BFDA BFD is a simple breakdown of a process into blocks or

units of operations which represent major parts of of the process being depicted.

PFDA PFD is a detailed breakdown of a process into symbols

which represent all major equipment and pipelines which are part of a process as defined by the BFD.

A PFD consists of the following: Diagram Drawing Numbered Pipelines which indicate Flow Conditions Major Control Loops

26

P&ID

A P&ID is a document which is developed and used by Engineers,Technicians, Technologists, Maintenance and Operations personnel to define a manufacturing system. It's intent is to communicate in detail the controls, instruments, piping, and equipment used to implement that system.

27

ScalePFDs should not be drafted to scale. However, their size should be compatible with that of equipment drawings.

Flow DirectionAs a rule, PFDs should be drawn from the left to the right in accordance with process flows.

SizeThe size of PFD should normally be A1 (594 mm 841 mm).

Fail Open / Closed (Control Valve): The safe position of a valve which will shift to upon loss of the power medium.

Normal Position (Valve): The position of a valve in Normal Condition of the process (N.O. , N.C.)

132

Plant Shutdown: The shutting in of all process stations of a Plant Production process and all support equipment for the process.

Process Shutdown: The isolation of a given process station from the process by closing appropriate SDVs to shut-in flow to the process station or divert flow to another process station.

Shutdown Valve (SDV): An automatically operated Normally Closed valve used for isolating a process station.

Emergency Shutdown System (ESD): A system of stations which when activated initiate plant shutdown.

133

Pressure Safety Valve (PSV): A pressure relief device designed to open and relieve excess pressure and to reclose and prevent the further flow of fluid after normal conditions have been restored.

Depressurization: When metal exposed to fire on one side with vapor on the other side, the metal temp. may reach a level at which metal rupture due to stress may occur, even though the pressure does not exceed the allowable overpressure. An emergency depressurization (blow down) system is provided to avoid such an occurrence.

Notes:1) Unit number for the equipment shall start from 1 (not from 01).

For a typical refinery units see Appendix A.2) Serial number for equipment including mechanical,

machinery, electrical, ancillary facilities, buildings, general items, etc., shall be from 01 to 99 unless otherwise specified. The numbering of instruments and control equipment should be from 001 to 999. For the units with more than one section (e.g., crude and vacuum distillation unit, etc.), equipment serial number to be utilized for each section shall be determined by the Contractor (e.g., from 01 t0 50 and from 50 to 99 to crude distillation and vacuum distillation sections respectively).

Notes:Notes:

1) Piping serial number, in general is started from 0001 and Up except for the units which are characterized by more than one section such as crude and vacuum distillation unit. In such cases, split of piping serial numbers to be assigned for each section of the unit shall be determined by the Contractor.

Special number 7001 : 9999 shall be used for all drains, relief headers and utility services including fuel oil and fuel gas for all units except for the units which are producing the subject utility services.

For assigning the piping serial number, the following items should be taken into consideration:a) The individual line number shall be held up to the point where the line ends at the inlet of

equipment such as a vessel, exchanger, pump, etc., an other number is required for the line downstream of the equipment.

b) All utility headers (systems) shall be numbered with their respective units. All branches serving a specific unit will be numbered with that unit.

f) All firewater and sewer branches serving a specific unit shall be numbered.2) Piping class code shall be in accordance with the line classes utilized in project piping material

specification.3) Piping components not identified by instrument or mechanical equipment numbers, etc., and

not covered by the piping material specification, are identified by a special item number.4) Unit number of the plant shall start from 1 (not from 01). For a typical refinery units see

APPENDIX LAPPENDIX LDEFINITION OF NOMINAL SIZEDEFINITION OF NOMINAL SIZE

1) DefinitionNominal size (DN): A numerical designation of size which is common to all

components in a piping system other than components designed by outside diameters or by thread size. It is a convenient round number for reference purposes and is only loosely related to manufacturing dimensions.

Notes:1) It is designated by DN followed by a number.2) It should be noted that not all piping components are designated by

nominal size, for example steel tubes are designated and ordered by outside diameter and thickness.

3) The nominal size DN cannot be subject to measurement and shall not be used for purposes of calculation.
