Abstract
This investigation was carried out to determine the solubility of ethanethi ol in a methyldiethanolamine (MDEA) solution. Measurements were made in the absence of acid gases, H2S and CO2, with individual acid gases present, an d with mixtures of acid gases present. Experiments with an aqueous solution of 50 mass % MDEA were carried out at 40 and 70 degrees C. The total press ure for most of the experiments was 6890 kPa, which was maintained by metha ne. Partial pressures of ethanethiol ranged from 0.2 to 15 kPa.
