Engineering analysis toolkit

Every calculator you keep in a spreadsheet, built in

78 standalone process-engineering calculators live next to your flowsheet — relief and flare sizing, psychrometrics, pumps and compressors, gas-pipeline flow, cooling towers and fired heaters. Each on a cited method. No install, no add-on license.

Reach for the right tool without leaving the browser

Open the Engineering Analysis panel from the workspace and pick a calculator. Property-dependent tools share the solver's property packages, so your hand checks and your full runs never disagree.
