Distillation Column Operation - Training Guide
============================================================

MINIMUM RESOLUTION: 980 x 600 px
RECOMMENDED: 1920 x 1080 (16:9) or larger

SIMULATOR OVERVIEW
----------------------------------------
Distillation column simulator covering tray hydraulics, reboiler/condenser control, reflux ratio, and product purity per ASME Section VIII and API 526.

Standards: ASME Sec. VIII · API 526 · DIERS

INTERFACE LAYOUT
----------------------------------------
- LEFT PANEL: System controls (Start/Stop/ESD/Reset, Mode toggle)
- CENTER: P&ID schematic with real-time process visualization
- RIGHT PANEL: System gauges, operational checklist, alarm list

OPERATING PROCEDURES
----------------------------------------
  Step 1: Line up feed, overhead, and bottoms valves
  Step 2: Start condenser cooling water
  Step 3: Start reboiler — establish heating
  Step 4: Fill reflux drum to operating level
  Step 5: Start reflux pump
  Step 6: Set reflux ratio to design value
  Step 7: Monitor tray temperatures — approach steady state
  Step 8: Sample products — verify purity

SCENARIOS
----------------------------------------

  Normal Startup:
  Establish reboiler heat, fill reflux drum, set reflux ratio, achieve steady state.

  Column Flooding Response:
  Detect and recover from tray flooding by adjusting reboiler duty and feed rate.

  Feed Composition Upset:
  Respond to feed composition change — adjust reflux and draws to maintain spec.

ALARM RESPONSE
----------------------------------------
  FLOOD_DETECT [ALARM]: Column differential pressure indicates flooding
  TOP_OFF_SPEC [WARNING]: Overhead product purity below specification
  BOTTOM_OFF_SPEC [WARNING]: Bottoms product off specification
  REBOILER_HIGH [ALARM]: Reboiler temperature exceeds limit
  REFLUX_LOSS [ALARM]: Reflux drum level critically low
