2.2.2 Completion of the process flow for the methanol storage tank (V1610) (including the process flow diagram and instrument data sheet):
2.2.3 Plan Layout of Combustible and Toxic Gas Detectors (Gasification Unit):
2.2.4 The process flow of the purification unit’s conversion section has been refined;
2.2.5 Completion of the process flow diagram for Liquid Ammonia Filling No. 1 (with the nitrogen pipeline added to ensure consistency with the existing site plan);
2.2.6 Completion of the process flow diagram for liquid ammonia filling at Unit 2;
2.2.7 Completion of the gas pipeline design for igniting the Claus furnace (the original design included PG20031, but it was not actually installed):
2.2.8 Completion of the process flow diagram for the main combustion chamber F2001 (original HAZOP report corrective action: Section IV, Node 6: In the PID drawing for the main combustion chamber F2001, there is inconsistency between the temperature tag numbers in the text description and on the drawing—specifically, the text describes furnace temperatures TT20005/6/7, while the control node labels on the drawing are TZT20006A/B/C; this lack of uniformity may lead operators to misinterpret the measurement points).
