PUBLIC DEMONSTRATION SYSTEM - SIMULATED DATA ONLY
No real plant is connected. This is an educational browser simulation, not operating guidance for a physical chemical plant or a fuel-quality certification system.
Try a blend in a few clicks
- Open Make a blend. Enter the desired final whole-tank inventory, for example 3 m³, and final bio-component fraction, for example 10%.
- Read the calculated base and bio additions. Existing tank contents are included. Incompatible recipes or insufficient stock/capacity are rejected.
- Select Allocate blend. This reserves the route without moving equipment. Select Start operation above the drawing.
- Watch the valves open and prove their positions. The base pump establishes flow before bio dosing begins. The two flow controllers regulate actual delivery.
- Completion is checked after both pumps stop and the valves close. Displayed quantities are actual integrated results, so small deviations are normal within stated tolerances.
Explore the plant
TK-101 stores base fuel. TK-102 stores bio-component. Both feed TK-201, where physical blending, agitation and simulated heating take place. P-201 either recirculates to TK-201 or transfers product to TK-301. Pump protective returns are distinct from delivered product.
Click a vessel for inventory and a connected-route view, or a pump/valve for actual feedback and protected controls. Operator SP (setpoint), PV (measured value) and output are visible in controller faceplates. Tuning stays in the collapsed engineering section.
Hold, stop and recover
| Action | What happens |
|---|
| Hold batch | Pumps stop safely. Recipe, actual totals and route ownership are retained. |
| Resume batch | Live conditions are checked again and the same operation continues. |
| Stop / Abort | Ends the operation with a recorded partial result. Abort initiates an urgent pump stop; isolation still waits for stopped feedback. |
| Clear injection | Removes the simulated cause only. It does not reset or restart the plant. |
| Acknowledge → Reset fault → Resume | Three deliberate recovery actions. Reset never starts a pump automatically. |
| Reset Demo | Restores inventories, equipment, controllers, history and scenario state. Your selected speed is retained. |
Eight guided scenarios
Normal transfer; automatic blend; recirculation/mixing/heating; restricted bio capacity; destination high-high; failed valve travel; pump trip; and Hold/Resume. Selecting a case previews it. Start scenario confirms a baseline reset, then allows four seconds to read the introduction. A demonstrated protection trip is an expected outcome.
Read the colours and trends
Grey: inactive. Dashed blue: allocated, no flow. Moving green line: actual product flow. Green valve: open feedback. Amber: transition. Red: fault. Cyan: manual control. Magenta/BAD: invalid critical data. An open valve does not guarantee flow.
PID & Trends plots the actual simulation history. Select traces with their engineering units. Click a chart to hold an inspection window and move the cursor; Return to live values releases it to inspect earlier values while the plant continues. Whole-tank bio fraction and incoming stream ratio are different measurements; uniformity is a separate educational proxy.
Alarms and events
Alarms and Events are separate screens. Entries record the local date and time they occur, independent of simulation speed. The UNACK shortcut and acknowledgement actions flash until every alarm is acknowledged. Acknowledgement does not clear an active cause or restart equipment.
Scenario introductions include Cancel start. Operation commands are locked during the countdown so they cannot conflict with the pending scenario.
Shared demo controls
The left navigation, telemetry strip, status summary and recent-alarm dock follow the TBC Power Management System demo. Speed, pause and reset sit beside the page heading. On phones, use the Page selector; detailed telemetry is available through equipment faceplates. Operation commands stay above the process drawing.
Speed and phones
Choose 1× real time, 10× demo, 30× fast or 60× explore. All physical dynamics use the same simulation clock. Use your phone in landscape and Expand drawing for Fit, zoom and pan. Portrait automatically pauses simulation time; rotating back releases that pause. A deliberate user pause or process fault remains in effect.
Model limits
All plant parameters are fictional. Volumes are reference-temperature m³ with constant densities of 830 kg/m³ base and 880 kg/m³ bio. No thermal volume expansion, reaction chemistry or product compliance is modelled. Source restart minimum is 5%; receiver targets are capped at 93%; low-low and high-high thresholds are 4% and 94%. Heating/mixing needs 0.8 m³. Heating temperature trips at 55°C. Component completion tolerance is ±0.005 m³; whole-tank bio tolerance is ±0.2 percentage points.
R07 drawing and operation controls
Overview shows the four tanks and main flows. Select a tank for its connected routes. Expand drawing preserves that view; use Fit, +/− and drag to inspect. Non-return valves are passive and have no operator pop-up.
Transfer, Make a blend, Recirculate and finished-product transfer each open a dedicated form. Allocate reserves the requested operation; Start initiates it.
TT-101, TT-102, TT-201 and TT-301 indicate tank liquid temperature. PT-101, PT-102 and PT-201 indicate pump discharge pressure. Select a transmitter for live readings and quality diagnostics. Empty tanks show NO LIQUID and failed signals show BAD.
In Help & Engineering, switch ISA-101 mode on for a neutral interface including a light header and full-colour logo, or off for TBC colours. Abnormal states retain distinct colours. This is a demonstration palette, not certification of ISA-101 compliance. See ISA101 scope.
Guided scenarios start on Overview. Destination high level stages the receiver at 90%, then applies an explicit inventory disturbance to 94.5%. This is separate from metered batch delivery. Material and energy are conserved between tanks. The receiver remains nearly full after the trip: acknowledge, then use Reset demo to restore safe baseline inventories. Clearing a forced signal alone does not clear the physical high level.
