Academic licenses subject to educational verification. Promotion codes activate full feature sets for verified student and faculty accounts.
Execute stepped equilibrium stage calculations in real-time as you adjust reflux ratio, feed quality, and composition targets. Watch theoretical plates recalculate instantly across the McCabe-Thiele diagram with dynamic operating line repositioning.
Access vapor-liquid equilibrium profiles for 50 industrially relevant chemical pairs including ethanol-water, benzene-toluene, acetone-methanol. Each system carries measured alpha values, azeotrope coordinates, and separation difficulty ratings.
Progress through 15 order-gated lessons building competency from equilibrium curve interpretation through optimal feed plate placement. Each drill unlocks upon successful design submission demonstrating concept mastery.
Manipulate reflux ratio R, feed quality q, distillate composition xD, and bottoms composition xW via precision sliders. Observe instantaneous recalculation of minimum stages N_MIN and reflux R/R_MIN ratio.
Save converged column configurations to the ledger with custom naming. Archive includes mixture identification, theoretical plate count, feed stage location, and reflux ratio for future reference and comparison studies.
Calculate flooding percentages using tangent method correlations with adjustable ceiling parameters. Verify hydraulic feasibility of theoretical designs before transitioning to tray sizing calculations.
Moon Jokeer implements computational algorithms derived from McCabe-Thiele graphical shortcut methodology validated against rigorous stage-by-stage MESH equation solvers. VLE datasets sourced from peer-reviewed chemical engineering literature ensuring thermodynamic consistency.
Moon Jokeer executes as a native Android binary leveraging hardware-accelerated rendering for smooth real-time graph manipulation during parameter sweeps. The calculation core employs optimized numerical methods to solve material and energy balances across theoretical contact stages while maintaining graphical representation fidelity.
Backend database stores pre-calculated vapor-liquid equilibrium relationships for 50 binary systems spanning polar-nonpolar, hydrogen-bonding, and associating mixtures. Each system entry contains discrete VLE points, Antoine coefficients for vapor pressure estimation, and documented azeotrope coordinates where applicable enabling accurate equilibrium curve generation.
The drill progression engine tracks user completion state across 15 sequential modules implementing unlock gates contingent upon successful design submission. Saved column configurations persist across sessions via local storage indexed by timestamp and user nomenclature facilitating longitudinal design comparison studies.
