Choose NRTL for non-ideal liquids and SRK for high-pressure hydrocarbons, then validate VLE data in DWSIM for reliable simulations.

BS EN 308:2022 guides cleanroom HVAC heat recovery, controlling air leakage, EATR and pressure balance to protect supply air quality.

Aspen Plus maps steam, condensate and drying losses across kraft mills, guiding BAT 6 heat recovery, pressure matching and fuel savings.

ESOS Phase 4 requires 95% energy coverage by 5 December 2027. Compare energy audits with pinch analysis to cut process heat costs.

Refineries use a 20-40°C minimum approach temperature to balance fuel savings, exchanger area, fouling risk and crude preheat run lengths.

Pinch analysis can cut pulp mill heat demand by up to 39%, recovering dryer exhaust heat, reducing steam and fuel costs, and guiding heat pump use.
