You don't say where it will be installed, what it will be connected to, and what type of storage will be (pressure, refrigerated). ¿How can a P&ID be provided even if we happen to have one available and without restrictions to distribute (I don't)?
I'd suggest you to read Lee Loss Prevention chapter 22 for a briefing on what is required.
Also API 2510 is a good reference.
Once what you decide what to include in the design, the P&ID is just drawing.

Following input is required for developing Propylene P&ID:
1) Capacity of Tank
2) Inlet to tank from Tanker / Process Unit.
3) Storage Condition - Refrigerated or Pressurized state ( As suggested by Mr. Saml)
4) Pump capacity
5) Propylene Users / distributions.
Based upon above input P&ID can be developed.
Hope this resolves your query.
Regards,
S.P.Chauhan

First of all, safe storage of propylene requires a pressure vessel, rather than a tank.
What Saml and spchauhan12 stated is right.
P&ID generation is just preparing a drawing using standard symbols used to represent the various unit operations.
Note the following steps:
1, A s a starting point,
It is advisable to read some standards like NORSOK P-100 & P-101 to understand the design and process control requirements.
Also check the local industry regulations, if any for handling propylene especially, because it is volatile.
2. Prepare a block diagram to satisfy your requirements.
Carefully select the process unit operations.
3. Carry out a conceptual simulation configuring with the appropriate unit operations and the flow rates.
Fix the range of prevailing storage temperatures and consequently the pressure.
4. Complete the process design with inherent safe design approach.
At this stage, use the relevant design standards followed by your company.
5. After this, prepare the P&ID
Note - Whatever P&ID you prepared is preliminary now.
Submit the P&ID for review to concerned review members in your company as per document review distribution matrix, carry forward with hazop sessions, incorporate comments and then you have the final P&ID
