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 t o 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 cl asses 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).

APPENDIX L DEFINITION OF NOMINAL SIZE 1) Definition Nominal 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.

SOME KEY ISSUES RELATED TO LAYOUT

Safety and Environment Familiarization with pertinent Environmental Regulations, (Local, National and International), and how they might change is essential perior to conclusion of pre-project studies. Attention shall be given to the pertinent safety regulations, including health and welfare needs. Hazardous and flammable materials require special handling, which can take up layout space. If the process fluids are especially toxic, layout is affected by the need for close chemical sewers and other protection measures. Security requirements may require special layout design when the plant produces a highvalue product. If a plant site is governed by particular building, piping, :H5@@J S)PN %-.=P0 5C^$ plumbing, electrical and other codes, these can affect 412 plant layout. Similar governing standards and regulation

Throughput It is important not only to know the initial capacity but also to have a good feel for how much the plant might be expanded in the future, as well as how hhow ow likely the process technology is to be modernized. These factors Thesewww.mblastsavior.mihanblog.com factors indicate how how much space should be left for additional equipment. Multiple processing lines (trains), are often required for f or the plant. Pairs of trains can either be identical id entical or be mirror images. The identical former option is less expensive. But the mirror image approach is sometimes preferable for layout reasons. Two such reasons are: a) For operator access via a central aisle. b) The need that the outlet sides of two lines of equipment :H5@@J S)PN %-.=P0 5C^$ 413 (pumps, for instance) point toward each other so that they the y can th ey be readily readill hooked readi hooked to one common common co mmon line. line.

BASIC CONSIDERATIONS General The plant layout shall be arranged for: a) maximization of safety; b) prevention of the spread of fire and also ease of operation; c) maintenance consistent with economical design and future expansion. Blocking The plant site shall be blocked in consideration of hazards attendant to plant operation in the area.

Roadways 1) Road and access ways shall offer easy access for mobile equipment during construction and maintenance, fire fighting and emergency escape in a fire situation. 2) Unless otherwise specified by the Company, the defined roads shall be made as stated in IPS-E-CE160, "Geometric Design of Roads". 3) Access roads shall shall be at least 3 m from processing equipment between road edges to prevent vehicle %-.=P0 5C^$:H5@@J S)PN 417 collisions.

Piperacks and Sleepers piperack for process Units and pipe sleeps for the off -site facilities shall be considered as the principals support of the pipe way Single level pipe racks are preferred, if more than one level is required, the distance between levels oriented in the same direction shall be adequate for maintenance but not less than 1.25 meters %-.=P0 5C^$:H5@@J S)PN

418

Maximum piperack widths shall be 10 m. If widths larger than 10 m are required, the piperack shall be designed to be of two stage. Actual widths shall sha shallll be 110% of the required widths or the required widths plus 1m. In cases where air fin coolers are to be placed on the piperacks, the piperack widths shall be adjusted based on the length of the air coolers. %-.=P0 5C^$:H5@@J S)PN

419

Allow ample space for routing instrument lines and electrical conduit. Provide 25% additional space for future instrument lines and electrical Provide 20% additional space on the pipe rack for future piping Pipe racks outside process areas shall have the following minimum overhead refinery/plant clearances: main roadway -5 meters , access roads -4.5 meters, railroads -6.7 meters above top of rail. %-.=P0 5C^$:H5@@J S)PN

Typical layout of piperack, for process plants depending on the number of process Units incorporated and the process complexities are given in Figs. 1 through 4 with reference descriptions as follow: a) "Single Rack Type" layout, is suitable for small scale process complex consisting of two-three process Units. It is economical without requiring any large area.

421

"Comb Type" layout shown in Fig. 2, is recommended for use in pr ocess, ocess, complex consisting of three or more process Units. "Single Rack Type" in this case will not be suitable since separate maintenance and utility administration in normal operation will be difficult because of the utility and flare line which are placed on the common rack.

423

"U Type" layout shown in Fig. 4, is recommended to be used in ca se of process Units whose maintenance cannot be conducted separately, within the complex. This type can be regarded as an expansion of the "Single Rack Type". Even process complexes of this nature, can be regarded as one process Unit in the planning of their layout.
