Refinery Flare Regulatory Compliance
At the 2020 4C Health, Safety & Environment conference, Emerson's Jamie Marsden presented, New Refinery Flare Regulations 40 CFR Part 63. The rule, 40 CFR 63 Subparts CC and UUU, affects any refinery with a flare used as a control device for an emission point, and...
Assuring Single-Phase Vapor Sample for Gas Chromatograph
Gas chromatographs analyze the composition of hydrocarbon mixtures in process and natural gas applications. For online natural gas chromatography, the samples must be reliably conditioned to produce a single-phase vapor. In this 5:42 YouTube video, How to Select a...
How to Set Up Gas Chromatograph Serial Communications
Gas chromatographs (GCs) are used in the oil & gas industry where critical measurement of the components in gas are required. GCs are used in custody transfer applications to more complex hydrocarbon C9+ analysis with dew point calculations, trace contaminant...
Reducing Project Execution Risks for Complex Analytical Systems
Real-time analyzers play an important role in many process manufacturing operations. Some examples include natural gas custody transfer, combustion efficiency monitoring, combustion emissions component analysis, flowing fluid compositional analysis and more. Not only...
Optimizing Refinery Fluid Catalytic Cracking Units and Vapor Recovery Units
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...
Laser Gas Analyzers for Optimizing Ethylene Production
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 Chromatograph Validation in Natural Gas Custody Transfer Applications
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....
Simplifying Continuous Gas Chromatograph Online Analysis Installation
Gas chromatographs (GCs) are used in natural gas applications to measure the hydrocarbon components. The heavier natural gas liquids beyond butane and pentane are referred to as C6+ hydrocarbons. Gas chromatographs performing C6+ analysis are used by hydrocarbon...
Improving Burner Control with Gas Chromatographs
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...
Wireless Gas Chromatograph Pipeline Composition Measurement
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 Chromatograph Installation Considerations
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...
