Suggestion: DP cell calculation should be re-checked after installation to consider the elevation difference between tie-in on the vessel and the capillary tube low point. (typical comment)



Incorporated, these DP cell calculation will furnished after installation to consider the elevation difference between tie-in on the vessel and the capillary tube low point. As mention in general notes no.5 sheet 1.

To clarify: The corrosion inhibitor skid tank level measurement not included in this document. To provide the visible range of LG at the referred point (next to the LG drawing). (typical comment) To clarify why the LG nozzle (N1A) elevation height is less than LT (N2A).



The corrosion inhibitor skid tank level measurement will be provided by Corrosion Package Vendor.



Folio 2 of 6



To confirmed the piping bottomconnection configuration of LG280201 to piping discipline.



Confirmed, this configuration will be provided with straight nozzle from nozzle.



Folio 2 of 6



To maintain the LG transparent type as per specification. (typical comment)



Incorporated, LG280201/280204/280103 will be change back to transparent type with suitable visible-length.



Folio 3 of 6



To confirm that the nozzle elevation height of LIT-360102 is suitable to perform the threshold alarm within 10% ~ 90% of signal.



Incorporated, bottom nozzle (N1B) for LIT-360102 move to elevation +100 so that the threshold alarm (LAL & LAH) will be 11.54% ~ 69.23% which is within the requirement.

Folio 3 of 6



To confirm that the nozzle elevation height of LIT-360107/360106/360105 is suitable to perform the threshold alarm within 10% ~ 90% of signal



Confirmed, those LIT have 48.61% ~ 83.61% alarm signal which is within the requirement.

Folio 4 of 6



To define the zero elevation for disposal tube level measurement.



Incorporated.



Folio 5 of 6



To confirm that the nozzle elevation height of LIT-280104 is suitable to perform the threshold alarm within 10% ~ 90% of signal



Confirmed, that LIT-280104 alarm threshold is within 10% ~ 90%.

Folio 6 of 6



To clarify: LG-700109 to have lower elevation height to indentify the liquid appearance inside the vessel.



The visible range of LG will be shown in the below table of each sheet respectively. Incorporated.



Confirmed, this LG-700109 can observe liquid start from elevation +296 from the tangent line which is adequate from process side (liquid will appear around +300 from tangent line). Also there are mechanical requirement that should be space on weld edge, therefore L1B at +210 is considerable the lower nozzle for this LG.
