The petroleum refining process is a marvel in how it converts crude oil into so many usable and valuable products and feedstocks for other products. If you're unfamiliar with the refining process or beginning your experience journey in the industry, I highly recommend...
The ethylene molecule consists of a double bond between carbon atoms and four hydrogen atoms bonded, two to each carbon atom. Per the Wikipedia Ethylene entry, it: …is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in...
Gas chromatographs (GCs) are used in natural gas custody transfer applications. They provide information on the gas quality and composition—with components such as methane, ethane and heavier hydrocarbons, water vapor, carbon dioxide, nitrogen and hydrogen sulfide....
There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more...
The Emerson Exchange conference goes way back several decades to the Provox Users Group. The meeting was started by users who wanted to give direct input to the leadership team on fixes, improvements and enhancements. This user led history carries forward to today...
Gas chromatographs (GCs) are used to analyze natural gas streams to identify the hydrocarbon components in order to determine the energy content of the gas. Natural gas is typically sold based on the amount of this energy delivered. The quantity of energy delivered is...
Hydrocarbon producers and transporters need to know the composition of the gases and liquids for accurate custody transfer and reliable, efficient operations. Gas chromatographs are often used to identify the composition of the fluids. In a Petromin Pipeliner magazine...
There is lots of excitement just east of us here in Austin for the 2014 Offshore Technology Conference (OTC2014) in Houston, Texas. One of the innovations being highlighted is Emerson's Rosemount Analytical 370XA gas chromatograph for natural gas measurement analysis...
In an earlier post, Measuring Liquefied Natural Gas, we looked at the move to liquefied natural gas (LNG) as a fuel for marine vessels. Emerson's Arjan van Ginkel gave me a peek at an unpublished whitepaper, Best practices for LNG measurement using Micro Motion...
In an earlier post, Measuring Hydrocarbon Dew Point with Gas Chromatographs, we highlighted the challenges with liquids in natural gas. Emerson's Jonas Berge added a comment [hyperlinks added]: The 700XA gas chromatograph can be integrated into intelligent device...
One of the challenges in measuring hydrocarbon gases is the precipitation condensation of liquids, which can impact measurement accuracy and create maintenance issues. Emerson's Shane Hale authors an article, Hydrocarbon Dew Point Measurement Using Gas Chromatographs...
We've explored in several posts the impact shale gas is having on the U.S. oil and gas industry. A Processing magazine article, US chemical industry expansion will bring sophisticated technologies mainstream, explores its impact on the chemical industry and the...
