Elaboration of review: 35. See document tagging philosophy as uploaded on 7-1-2016. Please also add TAG NO. for equipment, as per standard for projects. New pilot plant (all skids etc.) to be considered as 1 project .For example V-110, D-101, Z-104, E-101, S-109, etc. 47.So why is it necessary at SPDU II? 14. OK, who will decide and when? 51. Should be: block valve between header and skid for N2 (should be incorporated on the utility P&ID). 53. Review 1-9-2015 says:
SPDU I jacket HO1; SPDU II jacket HO2; SPDU II residue receiver HO1; Lab SPDU HO2; SPDU preheater HO1(current P&ID this is steam, steam is correct); SPDU degasser HO3. 52. OK, in these cases in the supply and return 3-way valves have to be used. Also draw a 3-way valve on P&ID. Handlebars of the 3-way valve for the supply and return can be connected by a bar, so both 3-way valves are operated in 1 move and will always be in the correct position. In this way the supply can not be connected to the wrong return. 62. No dry ice available, drawing with proposal will be uploaded. 63. Use of mercury is not allowed, so McLeod pressure gauge is not allowed. Please install electronic pressure gauge, same model as SPDU  I and II.
