ChemProCal is a comprehensive, cloud-based suite of chemical engineering calculators and process design tools built specifically for process engineers, mechanical engineers, and engineering students. Our platform bridges the gap between complex theoretical thermodynamics and practical, day-to-day equipment design, helping engineers move away from scattered, error-prone spreadsheets toward verified and automated calculation engines.
Our expanding library of rigorous, industry-standard engineering utilities covers a wide range of applications. Whether you are performing preliminary sizing calculations for complex continuous fractional distillation columns using McCabe-Thiele and NRTL property methods, analyzing two-phase fluid mechanics, sizing API 521 compliant knock-out drums, or estimating the required power for centrifugal compressors, ChemProCal provides fast calculations based on established engineering principles.
Every ChemProCal tool is designed around engineering equations and calculation methodologies relevant to real-world process design. We understand that accuracy and consistency are critical in process engineering. That is why ChemProCal incorporates features such as built-in chemical property data lookups, automatic unit conversions, input validation with engineering limit checks, and transparent calculation methodology.
ChemProCal is more than a collection of calculators—it is designed to connect engineering theory with practical application. Our Fundamentals Knowledge Base provides detailed explanations of the engineering concepts, governing equations, assumptions, and calculation logic behind many of our tools.
This allows students and early-career engineers to understand not only what a calculation produces, but also why it works. Experienced engineers can use the calculation methodology and intermediate results—such as analyzing heat exchanger LMTD or determining the Colebrook-White friction factor—to review assumptions and develop a stronger engineering basis for their preliminary designs.
Perform common process, fluid-flow, thermodynamics, equipment-sizing, and mechanical engineering calculations directly in your browser.
Support preliminary engineering calculations for separators, piping systems, compressors, pumps, heat exchangers, and other process equipment.
Learn the theory, equations, assumptions, and engineering principles behind the calculations through our growing knowledge base.
Reduce repetitive spreadsheet work with automated calculations, standardized units, validation checks, and clearly presented results.
Our mission is to replace scattered spreadsheets and expensive proprietary software with a unified, cloud-based platform that empowers engineers to design safer, more efficient, and optimized industrial processes. Explore the tools. Understand the engineering. Calculate with confidence.
