ASGMT has been providing Oil & Gas end-user personnel, manufacturing employees and university students the opportunity to obtain technical training from over 115 lecture classes and 48 hands-on equipment training classes.
Chromatography is one of the most widely used means of performing chemical analyses in the world. Russian botanist Mikhail Tswett is credited with discovering the technique of chromatography. Using alcohol as a mobile phase and chalk as a stationary phase, Tswett was able to separate various plant extracts. Figure 1. Example of Tswett’s Experiment Figure …

An ultrasonic meter falls into the classification of inferential meters. Unlike positive displacement meters that capture volume to totalize volume, inferential meters measure flowing gas velocity to totalize volume. Ultrasonic meters use sound waves to measure flowing gas velocity to infer volume. Ultrasonic meters have been around for many years, primarily in liquid measurement. However, …
There was once a time when you could get a car in any color…as long as it was black. They had frames, running boards and 15 horsepower engines. Who could ever need more? Just like the auto industry has adapted from this original approach to meet the demands of consumers, regulators and shareholders, the gas …
We study Engineering, Accounting, Business Management, Computer Science and a host of other curriculums on our way to employment. Technical schools teach us Ohm’s Law, Fundamental Physics, Chemistry, Electronics and Welding. Courses and complete degree programs in Leadership are available but for some reason, Effective Leadership is rarely taught in the disciplines found in our industry. While we admire sports heroes and winning coaches, how often do we admire winning CEOs or Managers? How many coaches, teachers or other people of influence have mentored us to success? How do we adapt the winning qualities we find in sports or college to Leadership in our careers? Sadly, Managers often lead or manage as they were managed. Traditions and bad habits persist as employees tolerate poor leadership and sometimes move to competition or out of the industry all together.
All around the world, propane, butane and natural gas must be odorized. The odorization ensures a safe transport, distribution and use of this valuable energy to residential buildings. Regulations vary from one country or state to another. The natural gas can be odorized at different points of the gas grid: in some countries (France, Spain, …
This paper is intended to provide meter station designers with a basic methodology for selection of an appropriate flow meter (or meters) for a given application. Since many applications require that a meter station operate over a broad range of flow rates or loads, an example is provided on how to address system rangeability while …
Today’s smart measurement devices produce significant diagnostics information. When the diagnostics from the various
devices are collected, trended, and integrated, operators can remotely and continuously identify measurement problems. The vocabulary associated with this topic is evolving. In the past, the industry used terms such as SCADA and Condition Based Monitoring to describe this process. These terms are being replaced by terms such as Industrial Internet of Things (IIoT) and Big Data Analytics, and even AI. In either case, this paper looks at the problems associated with collecting, trending, and integrating diagnostics information. It then gives examples of how diagnostics can be used to identify measurement problems. Finally, the paper provides an example of the reduction in exposure to Lost and Unaccounted For gas (LAUF) that operators may expect through implementing comprehensive diagnostic monitoring and analysis systems.
Thiols (i.e. mercaptans), sulfides, and tetrahydrothiophene (THT) have been widely used in the odorization of natural and liquefied petroleum gas due to the fact that natural gas does not possess an odor. Mercaptans, for example, have proven to be very effective in odorizing because of their low odor threshold and therefore, immediate impact on the …

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 capital and operating costs because they can record or integrate volumes at pressures and temperatures above the normal pressure base conditions specified in contracts for volume calculation. This allows …
