Accurate Measurement of Hydrocarbon Dewpoint in Natural Gas Streams Extraction of natural gas from shale formations has increased the focus on determining the quality of the gas extracted and processed. One of the key attributes of natural gas during its various stages of processing is its “Hydrocarbon Dewpoint”. This figure refers to the temperature at which the gas stream undergoes a phase transition to…

DETERMINING PROPER ODORIZATION LEVELS Over 300 people died in an explosion on March 18, 1937 in a New London, Texas public school building. The natural gas that was being delivered to the school building was not odorized. At that time the natural gas was odorless, and there wasn’t a law on record to mandate Odorization.

DEVICES FOR FIELD DETERMINATION OF H2O IN NATURAL GAS H2O vapor is an undesirable component of natural gas. It takes up space in the pipeline and provides no fuel value. In higher concentrations it can condense into liquid water in the pipeline and cause corrosion, especially in the presence of carbon dioxide or H2S. Liquid water can also cause damage to turbines. Because of…

ADVANCES IN NATURAL GAS SAMPLING TECHNOLOGY The monetary value of natural gas is based on its energy content and volume. The energy content and physical constants utilized in determining its volume are computed from analysis. Therefore correct assessment of the value of natural gas is dependent to a large extent on overall analytical accuracy.

Principals of Odorization In the one hundred and thirty years, or so that we have known natural gas as a fuel source in the United States, the demand for natural gas has grown at an astounding rate. There is virtually no area of North America that doesn’t have natural gas provided as an energy source. The methods of…

HOW TO PERFORM A LOST & UNACCOUNTED-FOR GAS PROGRAM Many (likely most) gas pipeline companies struggle with lost-and-unaccounted-for-gas (L&U) and it can be a significant cost to their bottom line as shown below. As shown in this inset, by reducing L&U from 0.6 percent to .25 percent, a typical company with a 2 BCF daily throughput could save Over 10 million dollars annually based…

AUDITING GAS LABORITORIES The data produced by Gas Chromatograph (GC) laboratories is used for many purposes, including product specification, accounting, safety and environmental compliance issues. The accuracy of this data has direct impact on all of these areas. Auditing laboratories responsible for producing this data is prudent business practice. The audit will provide a means of process improvement,…
