Developments in Custody Transfer Metering of Natural Gas

(P&GJ) — Natural gas has become an even more important energy source as the world looks to transition away from coal-fired power plants. Natural gas emits about half of the carbon emissions as coal, so it has many countries looking to adopt it as a larger part of their energy infrastructure.

Managing Lost and Unaccounted for Gas Volumes

(P&GJ) — Lost and unaccounted for (LAUF) gas is a calculated value that compares the amount of gas coming into a system (purchased) to the amount of gas leaving that system (sold or otherwise accounted for). Although LAUF is often equated to leaking pipes and equipment, leaks generally only represent a small portion of the value.

Importance of Moisture Analysis in Pipeline Transportation

(P&GJ) — Nearly every substance is affected by moisture, which can alter physical, chemical and electrical properties. When transporting hydrocarbons such as natural gas, the presence of moisture in the pressurized stream can create serious problems.
