Abstract: Gas quality and its accurate determination will assist in the prevention of the problems associated with freezing and hydrates in gas service. Measurement is only accurate under ideal conditions. In order for this condition to occur, contaminants must be removed from the meter run and pipeline. One of the contaminants that must be addressed is liquid in the meter run. According to data from Southwest Research Institute, one inch of liquid in a meter run can cause measurement errors in excess of 5%. These liquids may be water or liquid hydrocarbons. These same liquids, coupled with flowing temperature, ambient temperature, or pressure, will cause ice or hydrates to form.
