In April 1983, the third International Conference on Fluid Properties and Phase Equilibria for Chemical Process Design took place in Callaway Gardens, Georgia, USA. This event stimulated the Latin American participants to organize an International Course on the Thermodynamics of Phase Equilibria in Bahía Blanca (Argentine), in July 1984. This course brought a large number of participants from industry and universities, giving the chance to program scientific and technical interchange activities in the field of vapor–liquid equilibrium for process design. This was the first step for the series of EQUIFASE Conferences reported below, being held periodically:

EQUIFASE 1987 – Concepción, Chile

EQUIFASE 1990 – Salvador de Bahía, Brazil

EQUIFASE 1992 – Oaxaca, México

EQUIFASE 1995 – Caracas, Venezuela

EQUIFASE 1999 – Vigo, Spain

EQUIFASE 2002 – Foz de Iguaçu, Brazil and Argentine

EQUIFASE 2006 – Morelia, Mexico

EQUIFASE 2009 – Praia da Rocha, Portugal

EQUIFASE 2012 – Puerto Varas, Chile

EQUIFASE 2015 – Alicante, Spain

EQUIFASE 2018 – Córdoba, Argentine

The general purpose of the EQUIFASE Conference is to promote the Scientific and Technologic exchange between people from both the academic and the industrial environment from the European and American Continents in the field of Phase Equilibria and Thermodynamic Properties for the Design of Chemical Processes. The main topics of this Conference are related to measurement, modeling, prediction and simulation of physical–chemical properties concerning product and process design.
