Examples

View-only process examples and solved-case narratives.

These examples show how RHEON connects flowsheets, results, and use cases: not just diagrams, but the calculations and decisions behind them.

View-only solved depropanizer case

A public example can show the flowsheet, results, stage profiles, and study notes without exposing edit controls.

Gas processing

Natural-gas dew-pointing

Chill and Joule–Thomson expand a rich gas, then flash to drop out NGL — sales gas overhead.

Result view

Inspect separator vapor fraction, sales-gas composition, NGL liquid recovery, and cooler duty after the solve.

Economics

Estimate refrigeration/cooling load, valve/flash equipment, and annual utility exposure for screening studies.

Use case

Early dew-point control and NGL recovery screening before detailed plant simulation.

Rigorous separation

Depropanizer (rigorous)

Rigorous MESH column splitting an NGL mix — propane and lighter overhead, butane-plus in the bottoms.

Result view

Review stage temperature and composition profiles, distillate/bottoms splits, condenser duty, and reboiler duty.

Economics

Compare column utility cost, installed equipment cost, and annualized separation cost against alternate pressure assumptions.

Use case

NGL fractionation and column-spec review where a visible stage profile matters.

Reaction and recycle

Ammonia synthesis loop

Haber–Bosch loop: make-up N₂/H₂, recycle compressor, synthesis converter, refrigerated separator, and a purge to bleed inerts.

Result view

Track recycle convergence, purge behavior, synthesis conversion, refrigeration separator performance, and product ammonia flow.

Economics

Size compressor power, condenser cooling, and reactor/flash installed costs for study-grade alternatives.

Use case

Loop reasoning for reaction systems where purge, recycle, and separation decisions interact.

Utilities

Two-stage compression

Gas booster with interstage cooling — compress, cool, compress, cool to a pipeline pressure.

Result view

Compare interstage temperature, pressure ratio, compressor duty, aftercooler duty, and product conditions.

Economics

Break out power cost and installed compressor/cooler contributions for utility review.

Use case

Pipeline pressure boosting, staged compression, and cooler target selection.
