Carbon Black

Take charge of a furnace-process carbon black workshop. Each batch ships against a real tire grade order: N220, N330 or N660, each with its own DBP absorption target.

Master five production stages:
- Preheat the feedstock oil and ignite the burner inside the green zone.
- Balance fuel and feedstock to hold the reactor near 1800 degrees and make furnace black instead of thermal black.
- Hit the quench window to lock the DBP absorption value.
- Pulse the bag filter before differential pressure blinds the bags.
- Tune the water-powder ratio to build pellet strength.

Coins are paid from absorption value times pellet strength, with a bonus for on-spec grades. Spend them in the equipment shop on six permanent upgrades that truly change plant behavior: Precision Lance, Variable Quench, Online DBP Meter, Pulse Cleaning, Pellet Recipe and a Tire Plant Contract.

Custom themed dialogs, synthesized sound effects, persistent progress, and smooth canvas rendering. Pure offline fun for process-control fans.
