thermodynamic modelling of dissociation temperatures of carbon dioxide hydrates in the presence of acetone

In this work, dissociation temperatures of carbon dioxide hydrates in the presence of acetone which is a water-soluble organic promoter are studied# a simple model is proposed based on the enthalpy of hydrate dissociation for co2+acetone using genetic programming (gp) and teaching-learning-based optimization (tlbo) algorithm# moreover, water activity is calculated using the van laar activity coefficient model# ten sets of acetone and water mixture concentrations for the pressure range of 0#89-4 mpa are achieved from a previous experimental study by tatsuo maekawa# the aad for co2 hydrate dissociation temperatures was found to be 0#33 k, which indicates the accuracy of the model#
