## What is Process Engineer Calc?

ProcessCalc is an ad-free, offline-ready utility app designed specifically for chemical engineers, extraction technicians, and laboratory researchers.

Whether you are scaling up a synthesis from bench to pilot scale, optimizing solvent recovery, or sizing a chiller for your jacketed reactor, this app provides 10 specialized engineering calculators to streamline your daily workflow.

Key Calculators Included: • Solvent Recovery: Estimate evaporation rates and recovery times. • Chiller Sizing: Calculate required cooling capacity (kW) and tonnage. • Biomass Capacity & Yield: Optimize loading and predict expected yields. • Scale-up Predictor: Lab to production volume and flow rate scaling. • Condenser Area: Determine required heat transfer area. • Vapor Velocity: Avoid flooding in vacuum systems with min-ID calculations. • Pump Flow Rate: Quick displacement to LPM/LPH conversions. • Scaling Risk Predictor: Assess system scaling and maintenance needs. • Vacuum Diagnostic: Calculate rate-of-rise and system leak rates. • Compliance Map: Quick reference for global hemp/CBD regulations.

App Features:

Zero Ads: No pop-ups, no tracking, no subscriptions.
Offline First: Works instantly in the lab or extraction facility where internet might be spotty.
Favorites: Star your most-used tools for one-tap access.
Practical: Built around real-world formulas used in extraction and chemical processing facilities.
Designed by engineers, for engineers.
