How to use teqp Online

Use teqp online for cubic EOS properties and pure-fluid coexistence.

Evaluate Peng–Robinson or Soave–Redlich–Kwong cubic equations of state from supplied critical constants, or solve pure-fluid vapor-liquid coexistence below the critical temperature. No external fluid database or proprietary parameters are required.

How teqp Works

Upload Component Parameters as CSV with the exact documented headers. For methane, an example row is Methane,1,190.564,4599200,0.01142. Supply authorized critical constants and acentric factors.

EOS Properties uses Molar Density and reports calculated pressure and compressibility. This evaluates a specified state and does not perform mixture phase-stability analysis. Pure Fluid Coexistence requires one component, temperature below its critical value, and separated density guesses; pressure and fugacity equality are verified. All mixtures use classical mixing with zero binary interaction parameters. Results are in results.csv. teqp uses the NIST public-domain/foreign-rights permission notice; no trained weights are required.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.

Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.
