Please find our observations in P&ID (REV-A) and are not limited to the list given below. However this does not relieve you of your responsibilities to give all scope of supplies as agreed  and a system which will work smoothly meeting gauranteed parameters and as per good engineering practices.
1.Steam flow meter (vortex) is not mentioned in the P&ID
2.CIP return of stripper, ATFD is not shown. Pls. submit a separate CIP diagram also.
3.Process water is shown for stabilizing of stripper. We shall suggest you to use process condensate.
4.Connection of line no. P217-xx-SS to line no. P163-15-SS-xx should be after the tapping of line no. P195-25-SS-H-xx from line no. P163-15-SS-xx
5.Inline filter need to be shown in main feed line
6.Specification (sizes etc) of many lines is incomplete 
7.Capacity of CIP tank need to be revised from 2 KL to atleast of 5 KL size 
8.Pls. mention the equipment ID on the equipments also for our better understanding of P&ID
9.Can feed balance tank D-101 be avoided by connecting feed pump PU-101 directly with our main feed tanks (which are above ground ).    
However the tank   D-101 with all accessories will be utilized for other purposes.
11The common steam pressure control loop is shown on RLL side which is in TF scope. Pls. correct.
12.Pressure switch in Cooling tower header and Absolute vacuum transmitter in main vacuum line are not shown which are in your scope of supply.
13.Feed flow to stripper is shown controlled with stripper level whereas in the offer it is mentioned with level of first effect vapor separator (refer point no. 3.28.2 page 15 of 21. Hope this change will give the same desired effect 
and the system performance.
14.Input / Output signals of level transmitters and control valves not shown to be connected PLC/SCADA
15.FI & TI : are these digital or analog. it is to be clarified. The dispaly of TI,LI,PI should also be on SCADA as per the control philosphy.
16.Temperature, pressure, level, flow and other instrument are not shown to be connected to PLC.
17.Pls. show the safeties also to shut off the steam flow in case of any failure as per HAZOP study done by you.
18. water circulation in WRVP is through gravity or through pump, please clarify.
18.Pls. include RLL side equipments also as per the P&ID provided to you.
19.D-104 is to be shown with 1000 L capacity.
