BIAR Sampling Systems Liquefied Gas (LG) sampling Challenges: Liquefied gases such as Chlorine, Liquefied Petroleum Gas (LPG) and others are toxic chemical and no exposure is allowed for the operator. Proposal: To improve the current sample method by simplifying the process, reducing potential leak points and improving the general quality of the equipment, we propose using one of our valve with a sample cylinder and associated accessories such as bayonet connection and safety plug. To provide volume for product expansion, the valve must be installed on a vertical pipeline or at 90° on a horizontal pipeline as illustrated below: Bayonet adapter Bayonet adapter

BIAR Sampling Systems Liquefied Gas (LG) sampling The following illustration shows how BIAR COLUMBIA-LY sample container provide a sufficient vapor space to prevent overpressure from volumetric expansion. An increase in temperature causes the internal cylinder pressure to rise by the combination of volumetric expansion of the liquid (compressing the vapor space) and an increase in the vapor pressure of the contents. When used horizontally, BIAR sample containers COLUMBIA-LY create a vapor space that is necessary for volumetric expansion of the liquid. Vapor space ...

Liquefied Gas (LG) sampling Purely from the sample process point of view, the simplest and recommended way is to install the valve directly on the process line. However, if this is not possible, another recommended way is to install the valve on a fast loop between the high-pressure and low-pressure sides of the pump in a recirculation line. Assuming the valve is installed directly on the process line or on a fast loop with constant product flow-through, the steps to grab a sample will be the following: 1. Remove the safety plug from the bayonet connection (secondary containment) 2. Remove...

BIAR Sampling Systems Liquefied Gas (LG) sampling Some risks present in traditional sample methods are:     Numerous steps require the operator to handle multiple valves in a precise sequence in order to prevent exposure and guarantee a representative sample. There are numerous potential leak points The nature of some fittings (i.e. Quick-connect flexible tubing) present potential exposure risks A robust design is difficultly achieved due to small tubing and numerous equipment involved Example of Traditional system Sampling cylinder Quick‐connect Thread connection Flange Flange ...

BIAR Sampling Systems Liquefied Gas (LG) sampling To illustrate the complexity of the current sample method, below is an example of some of the steps the operator may have to follow in order to grab a representative sample in a safe way: 1. Remove the safety cap from the thread connection 2. Remove the safety cap from the sample cylinder 3. Screw the sample cylinder to the thread connection 4. Connect the quick-connect on the sample cylinder 5. Make sure Valve B is closed 6. Open Valve C 7. Open Cylinder Valve 2 8. Open Cylinder Valve 1 9. Open valve A 10. Wait a defined period of time 11....
