Using gc-ms and hplc-ms/ms for analyzing impurities in triethylene glycol accumulating in the process of natural gas drying

Abstract

Natural gas conversion is a complex dynamic process in need of constant monitoring. Improvement and automation of its steps is of great importance for upgrading quality and reducing cost. Conversion optimisation requires application of modern analytical instrumentation. Current analytical technics are time consuming, lack versatility and hardly prone to automation. In this work, development of comprehensive analytical procedure for control of triglycol contaminants accumulating during gas drying step is discussed. This procedure is based on LC-MS/MS, GCMS and multiparametric statistical analysis. The analytical procedure presented in this work is rapid and allows determining a wide range of triglycol contaminants.
