You probably need to be more specific. What is the service crude production? Do you have a known suction pressure and discharge pressure? Here are a few links to start your search:

thanks for your answer. to be more specific, I need a PFD or P&ID for Oil reception unit. I want to know the exact layout of the equipments to get ideas for my own design.

Dear Majid Izadiar

Good question

The process flow diagram (PFD) represents a quantum step up from the BFD in terms of the amount of information that it contains. The PFD contains the bulk of the chemical engineering data necessary for the design of a chemical process. For all of the diagrams discussed in this chapter, there are no universally accepted standards. The PFD from one company will probably contain slightly different information from the PFD for the same process from another company. Having made this point, it is fair to say that most PFDs convey very similar information. A typical commercial PFD will contain the following information:

1. All the major pieces of equipment in the process will be represented on the diagram along with a description of the equipment. Each piece of equipment will have assigned a unique equipment number and a descriptive name.

2. All process flow streams will be shown and identified by a number. A description of the process conditions and chemical composition of each stream will be included. These data will be either displayed directly on the PFD or included in an accompanying flow summary table.

3. All utility streams supplied to major equipment that provides a process function will be shown.

4. Basic control loops, illustrating the control strategy used to operate the process during normal operations, will be shown.

A piping and instrumentation diagram, or P&ID, shows the piping and related components of a physical process flow. It’s most commonly used in the engineering field.

P&IDS are foundational to the maintenance and modification of the process that it graphically represents. At the design stage, the diagram also provides the basis for the development of system control schemes, like Hazard and Operability Study(HAZOP).

For processing facilities, it’s a graphic representation of

Key piping and instrument details

Control and shutdown schemes

Safety and regulatory requirements

Basic start up and operational information

P&IDs are a schematic illustration of the functional relationship of piping, instrumentation and system equipment components used in the field of instrumentation and control or automation. They are typically created by engineers who are designing a manufacturing process for a physical plant.

What do you mean by "Oil Reception Unit"? Do you mean the crude tankage area? Do you also want to include intermediate tanks? Are you including the crude distillation unit tankage? What about slops tankage or individual unit tankage?

The short answer is the amount of tankage at individual refineries varies greatly according to their needs and perceived risk. Many refineries have grown accustomed to more tankage than they need and they pay a cost to maintain too much inventory. Other have intentionally reduced tankage and must occasionally live with suboptimal operation because of tankage issues that do not allow enough segregation of crudes and products.

You will find that each refinery is has unique tankage requirements based upon the segregation required for near optimal processing with their equipment and risks associated with supply chain issues.

many thanks for your responses. especially Prem Baboo for his precious ideas & Responses both in this subject and former questions.

Dear Rick Manner, by saying reception unit I meant a unit in the onshore area that deliver the crude oil from a platform to the refinery. in my opinion in this Unit we'll have a tankage area, some pumps of course, maybe some Heat exchangers and ... . I don't need a specific P&ID, any PFD or P&ID from any company would be enough.

Are these something like what you are looking for?
