Abstract Over the last three decades, the High‐Pressure Thermodynamics Laboratory at ESIQIE‐IPN has generated high‐accuracy thermophysical‐property data and contributed to the development and assessment of equations of state and molecular models for systems relevant to national and international chemical engineering. The discussion is organized around six interconnected research lines: (I) high‐pressure phase equilibria of pure fluids and mixtures; (II) volumetric properties (); (III) solubility and solid–liquid–gas equilibria in supercritical fluids; (IV) high‐pressure viscosities; (V) gas hydrate phase equilibria; and (VI) equations of state supported by molecular simulation. For each line, we highlight methodological innovations, experimental challenge, solutions, and representative case studies that illustrate how measurements and modelling were combined. We also discuss the scientific, academic, and emerging industrial impact of this work, including special issues in international journals, collaborative developments in equations of state, and applications in supercritical extraction and hydrate‐based separation processes. Finally, we outline open challenges for thermodynamics in chemical engineering, particularly regarding accurate descriptions of the critical region, compressed liquids, and environmentally benign separation processes.
