Process automation equipment including gas chromatographs and other process analyzers contribute essentially ...

  • Process analytics in gas-to-liquid (GTL) plants – Case Study

    NG, FT and GTL Natural Gas (NG) is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. NG is colorless, shapeless, and odorless in its pure form. It is combustible, and when burned it emits lower levels of potentially harmful byproducts into the air than other fuels. NG is a mixture of hydrocarbon gases. While it ...

  • Use of process analytics for cracking processes in refineries – Case Study

    Crude oil processing Crude oil is a complex mixture of hydrocarbon compounds and relatively small quantities of other materials such as oxygen, nitrogen, sulphur, salt and water as well as inorganics and metals. It occurs naturally in the ground and was formed millions of years ago. Crude oil varies from source to source in composition and colour. It is typically mixed with gases, which have to ...

  • Process analytics throughout the entire natural gas pipeline supply chain – Case Study

    Natural Gas (NG) Natural Gas is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful by products into the air. While natural gas is formed primarily of methane, it can also include smaller amounts of higher ...
