Impact of Liquid Volume Fraction on Accurate Measurement of Hydrogen Sulfide in Natural Gas Systems

Author: Paul Stockwell – Process Vision Abstract: Accurate measurement of hydrogen sulfide (H₂S) in natural gas is critical for safety, compliance, and operational performance. Now that liquid detection systems such as LineVu are detecting the presence of liquid carryover in natural gas streams at considerably higher levels than expected, this paper examines the partitioning behavior of H₂S between gas and liquid phases in the presence of condensate using Henry’s Law. A quantitative model is developed to show how increasing liquid volume fraction […]
What Is Liquid Contamination? The Hidden Threat Lurking in “Dry” Gas Pipelines

When pipeline operators talk about “dry gas,” they usually mean a stream that meets contractual specifications—often framed around hydrocarbon dewpoint limits and water content. Yet live visual monitoring tells another story: even gas that passes every lab test can still be laden with fine mists, stratified sheets, or slugs of liquid hydrocarbons, glycols, compressor oils, […]
How easy is it to install LineVu?

Why fast deployment matters more than you think In the world of gas transmission and processing, time is more than just money. It’s uptime, safety and operational control. That’s why when a new technology like LineVu enters the conversation, one of the most common questions is how easy is it to install? The answer is […]
Phase Separator Efficiency in Natural Gas Processing: Understanding the Risks and Solutions

Phase separator efficiency is a critical factor in ensuring the quality of natural gas in a transmission system. In this blog, we will examine the role of separator efficiency in natural gas processing, the impact of poor separator efficiency on the pipeline, and what steps can be taken to optimize separator efficiency. Before natural gas […]
Pipeline Pigging: Maximizing Efficiency and Minimizing Threats to Assets

Pipeline pigging Pipeline pigging is a vital process within a natural gas transmission system, playing a crucial role in maintaining efficiency, safety, and compliance with industry standards. The term “pipeline pigging” refers to the practice of using devices to perform various maintenance and inspection tasks within the pipelines. These tasks range from cleaning and removing […]
What is Liquid Carryover? Understanding the Impact and Prevention

In various industrial processes, especially in fields such as chemical manufacturing, oil and gas, and power generation, the proper separation of gas and liquids is crucial. One significant challenge that engineers and operators often encounter is the phenomenon known as “liquid carryover.” This occurrence can have detrimental effects on equipment, product quality, and overall process […]
