Application of an isokinetic probe for steam quality and purity in geothermal energy

Thesis (M.S., Mechanical Engineering)--California State University, Sacramento, 2015.This paper presents a review on the application of process sampling with respect to the\ud geothermal power generation industry. Specifically, using an isokinetic probe to take a\ud representative sample of geothermal steam for steam quality and steam purity analysis.\ud During the geothermal energy production process, naturally occurring non-condensable\ud gases (NCG) and geochemical species are present in the geothermal steam flow.\ud NCG poses several problems with respect to power generation, process engineering, and\ud energy economics. Naturally occurring chemical species, for example chloride ions,\ud entrained in geothermal steam is a source of corrosion in turbines and power plants. NCG\ud interferes with power generation as well. In order to correct for accurate steam enthalpy,\ud the amount of NCG present in the sample must be analyzed and quantified in order to\ud make accurate predictions about power generation and downstream corrosion.Mechanical Engineerin
