PEI has performed extensive mercury mapping studies identifying and characterizing mercury sources and distribution in entire gas production fields, in gas production equipment on offshore platforms, in natural gas separation and dehydration plants, in midstream gas processing plants, along major natural gas transmission pipelines, and in oil refineries.
These studies have provided accurate data for mercury removal unit (MRU) design and determined the distribution and flux of mercury through gas gathering and processing systems.
PEI has designed and implemented monitoring programs for compliance with gas quality agreements at custody transfer points. In addition, PEI has designed gas quality compliance programs including continuous monitoring programs with relative accuracy testing audit components to verify the functionality and accuracy of continuous mercury monitoring systems.
PEI uses state-of-the-art technology and equipment to measure and analyze mercury in hydrocarbon process streams and is capable of measuring mercury in parts per trillion ranges. The risk to process equipment through liquid metal embrittlement (LME) and/or amalgam corrosion (AMC) on aluminum heat exchangers are well documented. PEI advises clients on analytical methodology and procedures and provides qualified sampling teams to collect and analyze hydrocarbon process stream samples for computational modeling.
PEI uses computational modeling based on mercury concentrations, fluid dynamics, and process thermodynamics to predict the amount and location of mercury in process systems.
