Bucket sampling in petrochemical refineries isn’t new, and it isn’t very effective. Bucket sampling involves an operator simply walking up to a spigot, turning it on and collecting the sample in a bucket or other container. The samples pulled from a spigot may not be fresh or representative, or they could be impacted by exterior elements like fluctuating temperatures - both of which could foul the sample. Sampling this way involves additional significant safety risks to the operator, which can cost in manpower and money. Factor in the time it takes an operator to capture a sample and the logistics involved in getting it to the lab, and soon what was thought to be an easy and cheap sampling method is anything but.

Running an efficient operation requires analysis of controlled, real-time data obtained through representative sampling within a production environment. This data is needed to provide the critical insights needed to control and optimize processes. Representative sampling is the act of capturing fresh product from the process stream for analysis.

In the petrochemical industry, representative samples of liquid petroleum gas and other high vapor pressure gases and liquids are needed for process monitoring, quality control and regulatory compliance. However, in this industry, process fluids and gases are volatile or could be harmful to the operator and the environment, or they could be dangerously altered through a chemical reaction when exposed to the atmosphere – so exposure must be avoided. Because each sample collected may pose a physical or health hazard, and operators may take hundreds of samples per year, samples must be taken safely and correctly using the appropriate equipment and containers.

Sampling can be used to identify process variations and for process control, environmental monitoring, product quality assurance and custody transfer. Following proper steps reduces sample to sample variation. Characteristics of one representative sample are the same of that of the entire lot or batch – and the sampling methods and results should be consistent, accurate and repeatable.

Metal corrosion is inevitable, and has the potential to cause catastrophic pipeline and assets failure, damaging the environment and communities, injuring field operators, and causing costly downtime and waste in productivity.
