The modified square well potential is combined with perturbed-hard-trimer-chain (PHTC) EOS to predict the Solubility parameters of several fluids including alkanes, refrigerants and molten polymers. The performance of the proposed model has been evaluated by predicting the Solubility parameters of 12 hydrocarbons, 3 refrigerants and 12 polymers. Out of 263 data points for hydrocarbons and refrigerants, the average absolute deviations percent (AAD%) of the predicted densities and Solubility parameter from the experimental ones were found to be 1. 74% and 1. 09%, respectively. Additionally, out of 1993 data points of 12 polymers, the AADs% of the predicted densities were found to be 0. 43% and out of 60 data points examined, the AAD% of the predicted Solubility parameters from the experimental ones were found to be 0. 56%, respectively.

The role of carbon dioxide in global warming is one of the contemporary environmental issues, making necessary access to the technologies capturing the released CO2 into the atmosphere. Amino acids have the same amine functionalities as alkanolamines with similar behavior towards CO2 absorption. The Solubility of carbon dioxide in potassium glycinate (KG) solutions with different concentrations at various temperatures was measured. On the basis of the results, the mole of CO2 adsorbed, CO2, absorbed n, increases by temperature and the concentration of KG. The CO2, absorbed n versus the KG concentration at different temperatures was fitted with a sigmoidal function, so that the moles of CO2 adsorbed can be reproduced in the temperature range of 300. 15-327. 15 K and the concentrations of 0. 01-1. 00 M of KG within the experimental errors.

Seifert Fibre Groups (SF-Gps) have been introduced and their first derived groups have been worked out in an earlier paper by the author [2,3]. Now we aim to prove that they are residually soluble and residually finite.
