Carryover as an Integrity Threat
Why liquid contamination is a governance issue For years, liquid carryover in gas pipelines has been treated as an operational inconvenience, something to be managed within acceptable limits, mitigated through separator performance, or resolved through maintenance cycles. But this framing is fundamentally incomplete. What has changed is not the phenomenon itself. Liquids in natural gas […]
From Observation to Digital Twin: How Visual Data Becomes Predictive Control
In gas processing and transmission, visibility has always mattered. Operators need to understand what is happening inside separators, filters, and pipelines if they are to protect assets, maintain performance, and avoid contamination events. But visibility on its own is only the starting point. Seeing mist formation or liquid carryover in real time is valuable because it confirms […]
HCDP ≠ Confirmed Dry Gas
Why hydrocarbon dewpoint alone cannot prove single-phase flow in natural gas pipelines For decades, hydrocarbon dewpoint (HCDP) has been treated as the accepted reference point for declaring natural gas as “dry.” It is included in many contracts, specifications, and operating assumptions across transmission, processing, and custody transfer. The logic seems straightforward: if the reported hydrocarbon […]
Mind the Gap: Bridging Gas-Quality Theory and Pipeline Reality
See the unseen and protect the pipeline: those objectives underpin contemporary gas-quality assurance. Industry practice has long relied on a single parameter—hydrocarbon dewpoint—to certify a stream as dry. However, when Hydrocarbon Dewpoint (HCDP) is determined by gas Chromatography. The heavier hydrocarbons are combined and measured as one figure (C6+). While this is adequate for Btu […]
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 […]
