Please see our comments below and reply. 

1.	Flow Rates are not mentioned for FT-115

2.	Specific Gravity is not mentioned for PT-103, 10, 106 & 109

3.	PT-111 & PT-112 shall be DPT-111 & DPT-112

4.	In order to decide the insertion lengths of temperature elements, we need following details i.e. 
a.	Vessel Diameter 
b.	Insulation Thickness for pipelines & vessels

5.	For most of the tanks in P&IDs, Level Switches are shown  similar to that of Level Transmitters. Level switches could be either Top Mounted or Side mounted. You need to specify the requirement of Low Level or High Level detection. Normally, switches are displayed as LSH or LSL. If process requires LSH & LSL then Top Mounted Float Type Switch can be used.  Please confirm requirement of LSH or LSL as this will have an impact on I/O count.

6.	For Level Transmitters external chamber will be required. A center to center distance between the flanges for connection of external chamber is required.

7.	Is external chamber for Level Transmitter is in scope of Technoforce? If not, the gasket material needs to be specified for all Level Transmitters. 

8.	There are no local Temeprature Gauges & Level Gauges. These are recommended at least at critical locations. 

9.	It is recommended to have an Actuated on/off valves on Nitrogen lines to ATFEs. These valves can be opened by operator from control room whenever required or it can be interlocked such that it will be opened automatically on failure of vacuum system. 

10.	It is recommended to have flow meters on Steam, Cooling Water, Hot Water & Chilled Water Headers to give an idea of overall utility consumptions. 

11.	It is recommended to have Temperature & Pressure Transmitters on Steam Header.

12.	It is recommended to have Temperature Transmitter & Flow Switch on Cooling Water, Hot Water & Chilled Water Header. 

13.	Distillation P&ID shown co-current flow at Reboiler (#20). Please check for correctness.

14.	The no of motors with VFDs are increased. This will increase the cost of MCC Panel.
