Making the Right Selection (Coalescer vs Filter‐Separator)
Recorded On: 11/12/2019
The selection of a natural gas pipeline filter is a simple task that is as easy as selecting a valve,flange gasket, or any other commodity product. Almost nothing could be further from the truth!
Gas phase filtration and separation is a mature science. It is very predictable when contaminant species are known and exist at a relatively constant concentration. Predictable contaminant conditions are rarely experienced in natural gas pipelines. Natural gas pipelines can contain condensed hydrocarbon liquids, produced water, reservoir and well completion solids, pipeline degradation solids, well head chemicals, pipeline treatment chemicals, processing chemicals, and compressor lube oils just to name a few. Two or more of these contaminant species will commonly mix and create contaminant mixtures that can be challenging to remove. Pipeline contaminant concentrations can be drastically changed by the separation effects of elevation changes and by processing equipment upsets. Equipment application standards do exist. However, navigating these treacherous separation waters will commonly prove to be a stressful experience.
One of the most common decisions faced is the choice between selecting a gas phase filter-separator versus a gas phase coalescer. The contents of this presentation are being made available to help provide clarity and reduce the stress a little. Parker Hannifin’s Industrial Process Filtration Division (responsible for PECO brand products) has completed extensive controlled‐environment pilot tests to compare the two technologies. Data from the pilot tests will be reviewed to uncover important operational aspects. A simple understanding of how the two technologies operate will hopefully help readers with future equipment selections.
