LineVu 100

LineVu reveals contamination in high pressure natural gas systems that until now has been undetected. Despite commercial and legal contracts requiring that no liquids or solids should enter a gas network, it is common to find that liquid contamination is the cause of damage to power stations and other plant all over the world.

By monitoring the efficiency of gas/liquid separation systems, LineVu provides game-changing safety and financial benefits.

LineVu is a camera system that can be permanently installed on high pressure natural gas systems. When installed downstream of a gas/liquid separator it provides a live video stream of the gas leaving the separator system. Image processing is used to provide operators with a highly sensitive alarm if there is a break-through that contaminates the gas stream.

By monitoring the efficiency of gas/liquid separation systems LineVu provides game-changing safety and financial benefits. 

Liquid carryover in gas treatment causes foaming in amine and glycol contactors. Normal practice is to use de-foamer to recover from a foaming event. This often requires a reduction in gas flow rate until the foam is under control. Current practice is to monitor pressure drop across the contactor. Now, with LineVu reporting a carryover event before foaming starts, de-foamer can be added to prevent foam rather than recover from it, without loss of production.

After gas treatment, it is important to recover as much of the premium condensate from the gas as possible. Processing liquids (usually glycol) can be carried over from gas treatment and freeze in the dew pointing equipment. This causes temperature control problems and can partially block the liquid removal process, and a combination of glycol and condensate are lost down the gas export line. When LineVu reveals liquid carryover from gas treatment, flows can be adjusted to find the optimum flow until the problem is diagnosed and repaired.

Using LineVu at custody transfer points improves accountability for pipeline contamination incidents. Gas is bought and sold at custody transfer points on a dry gas basis. LineVu is revealing glycol and compressor oil carryover that, up to now, passed on-line gas analysers without tripping an alarm. With the extra knowledge that the gas is wet, flow computers can be corrected, operators can make better decisions regarding the acceptability of gas, and pigging operations can be optimised.

Key Features

Detection of Pipeline Contamination using Image Processing 
Machine Vision Camera

Machine vision camera, monitoring gas flow 24/7.

ease of installation

Certified for hazardous areas, optional flange adapters available to enable quick installation to various flanged tapping points.

Continous Monitoring

All data is stored on-site, with an optional cloud based access.

Pipeline Detection

Using the latest in machine learning, the gas process is monitored continuously for liquid carry-over events.

Evidence-based Decision

We believe that process supervisors and operations teams should have the best information possible in order to make the best operational decisions.

Instant Process Alarms

Operators are given immediate notification of pipeline contamination events.

Control Room Access

Live video feed of the pipeline activities can be provided to the control room, to help close the loop on gas quality control.

Providing our customers continous pipeline monitoring​

LineVu has been installed in many gas processing site, from the UAE to Canada

User Benefits

When natural gas is processed, liquids are injected to remove water vapour, carbon dioxide and hydrogen sulphide. It is vital that these liquids are completely removed from the gas stream prior to exporting the gas for sale yet, to date, there are no effective methods to  determine if liquid separators are working to their stated efficiency 100% of the time. Often operators find out too late that there is a problem with liquid carry over causing $Ms of damage.

Deployment Options

LineVu Local

Monitoring natural gas contamination events as a process control parameter, the Camera Can is cable linked to a safe area controller, where image processing provides a live video stream and local alarm. This system may provide video and data to the site local network.

Up to 48 Camera Cans may be connected to the site controller, installed in a safe area.

LineVu Remote

LineVu Remote includes an uplink to a secure server (either Process Vision’s or the Client’s server) allowing both remote and local access to live-streamed video. 

An encrypted user interface is available to password protected users who may be a central technical resource, a control centre (for unmanned sites), or the user’s client (in the case of custody transfer).

LineVu Mobile

LineVu mobile is used for temporary installations for surveys and de-bottlenecking projects. It combines the previous two versions.

The Camera Can is cable linked to a Pelicase-mounted controller and uplink system giving the user a choice to store locally or live stream to store video and data on a remote server.
