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. The largest source of analytical error in…

VARIOUS METHODS CAN BE USED TO VERIFY GAS CHROMATOGRAPH AT CUSTODY TRANSFER LOCATIONS Most “On-line” gas chromatographs operate for long periods of time without developing biased or even outright unacceptable measurement. Therefore, most users undertake system- wide performance testing infrequently. But as rising gas prices demand increased scrutiny on measurement data – flow volume, energy content, and often hydrocarbon dewpoint analysis — many measurement staffs may search for…

EFFECTS OF ENTRAINED LIQUID ON ORIFICE MEASUREMENTS Natural gas often has some liquid content. The liquid may be water, hydrocarbons, or compressor oil. As the gas flows through an orifice meter is the gas being measured correctly? The measurement methods and calculations described in ANSI/API 2530 are for dry gas. Many researchers have studied the effect of entrained liquids on orifice measurement.…

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 the equipment utilizing…

FUNDAMENTALS OF NATURAL GAS CHEMISTRY In order to understand the chemistry of natural gas, it is important to be familiar with some basic concepts of general chemistry. Here are some definitions you should know: Matter – anything that has mass and occupies space. Energy – the capacity to do work or transfer heat. Elements – substances that cannot be decomposed…

FIELD INSPECTION AND CALIBRATION OF MEASUREMENT INSTRUMENTS Timely, diligent field testing and calibration of gas volume recording and correcting instruments ensure that measurement information fairly represents actual volumes. The instruments save a company capitol and operating costs because they can record or integrate volumes at pressures and temperature above the normal pressurebase conditions specified in contracts for volume calculation. This allows the…

CALIBRATION STANDARD GASES Calibration standard gases are essential to quantitative analytical measurements in petrochemical processes, natural gas, environmental compliance, and health and safety programs – among others. The calibration gas standard establishes a known analyzer response to a certified chemical component concentration which enables the conversion of sample responses to a concentration with a determinable accuracy. In consideration…

FLOW CONDITIONING AND EFFECTS ON ACCURACY FOR FLUID FLOW MEASUREMENT – AMERICAN SCHOOL OF GAS MEASUREMENT HOUSTON 2006 GAS FLOW CONDITIONING Over the last several years research has shown that by improving on the flow conditioners used in natural gas metering applications, measurement is improved and installation cost can be reduced. The new standards developed for orifice meters (AGA 3/API 14.3 and ISO 5167) addresses the question of flow conditioner design and testing to ensure the…

TECHNIQUES OF COMPOSITE GAS SAMPLING The level of interest in effective and accurate gas sampling techniques is currently at a very high priority within the natural gas industry. With the fluctuating ranges in natural gas prices, exploration interests, profitability, deregulation and consolidation of the work force, recoverable revenue must be accounted for. At large volume delivery points, a 3-5 BTU…
