Chemical & Pharmaceutical Engineering Calculators

The everyday sums of a pharma or chemical plant: solvent recovery, heat load, agitation, filtration, centrifuge cake, pump power and corrosion. Built for process engineers, production teams and engineering students.

Solvent Recovery

Batch vacuum distillation in four parts: boiling point at vacuum, heat load & recovery time, condenser sizing and vacuum pump capacity.

Open Calculator

Heat Load & Recovery

How long will the batch take to strip, and how much heat does it need? Opens straight into that part of Solvent Recovery.

Open Calculator

Mixing / Scale-up

Put reactors from different plants or scales in one table. Reynolds number, tip speed, power, P/V and torque for each.

Open Calculator

Agitator Simulator

Compare two agitator setups side by side: animated flow pattern, blend time, solids suspension and crystallisation for 17 agitator types.

Open Simulator

Filtration Evaluation

Enter your Büchner trial readings and get specific cake resistance, flux and a Good/Moderate/Slow verdict.

Open Calculator

Centrifuge Cake Weight

Basket centrifuge cake weight and G-force from basket geometry, cake thickness, and bulk density.

Open Calculator

Pump Power Rating

Theoretical hydraulic power, pump shaft power, and motor power from flow, head, and efficiencies.

Open Calculator

Corrosion Coupon

Weight-loss corrosion rate (mpy) from coupon exposure data, with an Excellent/Good/Satisfactory rating.
