In chemical plants, refineries, and oil and gas facilities, sampling panels play a crucial role in industrial fluid sampling operations. Also known as field sampling, spot sampling or simply sampling, this operation helps operators validate process conditions, ensuring that the final product has the desired characteristics. The methods for carrying out sampling vary depending on the process fluid. For example, when sampling gases and volatile liquids, the sample should be collected in a sampling cylinder to prevent the gas or liquid from escaping and to protect operators from potential hazards.

In this blog we will explore the proper techniques for bottle sampling, the challenges that can arise during the process and how the correct design of the sampling system can bring significant benefits to your operations. What is Bottle sampling? During the sampling process, a representative sample of fluid is drawn directly from a pipe, reservoir, or system. It is then transported to a remote laboratory for analysis. To obtain the sample, the sampling panel incorporates a sampling valve. This is a critical component necessary for operator safety, ease BYB Directory of sample extraction, consistent sample volume control, and efficiency. The sampling process is developed as follows: The bottle is inserted into the panel sampling valve cover. When the bottle is inserted, the rubber septum is pierced with two needles: one that fills the liquid and another that allows air to escape. The operator opens the sampling valve, allowing the liquid to fill the bottle.
When the bottle is filled to the proper level, the valve is closed and the sample bottle is removed. Challenges of Bottle Sampling Field engineer using sampling systemWhen using a bottle sampling panel for sampling, it is not uncommon for the sampling valve to require maintenance due to a clogged, bent or broken needle. For this reason, facilities may prefer to use sampling valves that include a replaceable needle assembly. This design allows the operator to remove the needle from the valve body—allowing the assembly to be cleaned or replaced without needing to change the sampling valve itself. However, although the use of a replaceable needle assembly makes maintenance easier, it can also present new difficulties. This is because the rubber O-rings used in most replaceable needle assemblies can harden or degrade over time, causing leaks into the fluid system.
