**1. Completed Activities**
None.
**2. Pending Items & Look-ahead**
The plant is currently in preparation for startup, with the following sequence of activities planned:
* **Pre-Startup Line-up & Utility Readiness:**
* Line up plant and main process for startup.
* Initiate hot oil cold circulation (confirm PD-601 level ≥ 15%).
* Receive DIW, LPW, MPW utilities.
* Start PP-502A(B) (control PC-2502 = 12.5 kg/cm²), PP-503A(B), PP-504A(B), and PP-304A(B).
* Prepare and warm up condensate drains PE-502, PE-503, PE-504.
* Start lube oil system PM-401A/B.
* Introduce steam to tracing line jacket pipe and valves.
* **Cold Circulation, Pressurization & Heating:**
* Start main process cold circulation and pressurize.
* Pressurize feed and reactor to target 65 kg/cm².
* Start hot oil cold circulation (PP-601A(B)(C) AUT start by B/M).
* Perform F/O check H.O inlet PF-601 (balance 4 lines approximately 30 min after PP-601 start).
* Heat up H.O. by igniting main burner one by one (rate: 50°C/hr).
* Heat up main process by Hot oil and pressurize crystallizer (PE-601, PD-1205).
* **System Startups (Separation, Dryer, RPF/RVF):**
* Start separation and dryer system.
* Line up and warm up RPF (PM-401D for 2 hours), then start RPF.
* Line up loop RVF.
* Prepare and start PP-601 (two operation modes).
* Start PP-402(A)B to RVF.
* Start lube oil dryer and loop dryer (raise level PD-501).
* **Feed Introduction & Slurry Management:**
* Switch LPW to recycle solvent via PD-101 and re-slurry operation route.
* Confirm PG of RD before starting TA feed.
* Prepare and start TA feed via re-slurry operation route (initiate SEQ LC-2301-2303 OPEN/CLOSE).
* After TA feed completion, stop PM-102.
* Start PM-901.
* Prepare and execute switch from recycle slurry to normal operation.
* **Post-Startup Checks:**
* Start Exapilot program.
* Perform I/L confirmation check.
* Confirm drum levels (LOCAL & DCS).
**3. Issues / Remarks**
* Preparation and reception of utilities encountered an unspecified issue: "sd'gjs JB bJBP (PIC: PE)".พบข้อมูล 43 รายการในไฟล์นี้ การนำเข้าจะเขียนทับข้อมูลปัจจุบันทั้งหมด คุณแน่ใจหรือไม่?
