Standard Practice for Sampling Steam

Importancia y uso:

5.1 It is essential to extract and transport steam in a manner that provides the most representative sample of the process steam in order to accurately determine the amount of all impurities (dissolved chemicals, solid particles, chemicals absorbed on solid particles, water droplets) in it (1).3 An accurate measure of the purity of steam provides information that may be used to determine whether the purity of the steam is within necessary limits to prevent damage or deterioration (corrosion, solid particle erosion, flow-accelerated corrosion, and deposit buildup) of downstream equipment, such as turbines and process heat exchangers. The sources of impurities in the steam can include boiler water carryover, inefficient steam separators, natural salt solubility in the steam and other factors. The most commonly specified and analyzed parameters are sodium, silica, iron, copper, and cation conductivity.
