PREPARING SOLUBILITY DATA FOR USE BY THE GAS PROCESSING INDUSTRY: UPDATING KEY RESOURCES

摘要

In 2011, the GPA and GPSA undertook an effort to update parts of the GPSA Engineering Data Book with recently-generated data from GPA-funded research projects along with some of the most recent data available in the literature. Specifically, a wealth of data that describes the solubility of hydrocarbons in amines and glycols, the solubility of H2S and CO2 in glycols, and the solubility of methanol in gas and liquid hydrocarbon phases were evaluated in GPA Projects 975-5, 975-7, and 975-8, respectively. Because equations and graphs presented in the Engineering Data Book are frequently used for process calculations, material balances, and estimates of emissions in gas processing, it is important that these resources reflect the full body of data that have been generated. The focus of the work was to summarize the data into forms that would be convenient for use in quick and approximate manual calculations. The work resulted in the production of products that more accurately represent the data over a wider range of conditions. In particular, various graphs available in the most recent (12th edition) of the Engineering Data Book were updated and new equations describing the data were presented. This paper reviews the original data given in the current Engineering Data Book, discusses the source data used in this project, describes the methods and techniques used to analyze the data, provides the new representation of these data, and discusses the uses and limitation of these new and updated resources.
