The presence of mercury in most natural gas fields is undeniable with concentrations ranging from anywhere between <10ppb to >1ppm. It exists in the form of organic, inorganic and also elemental (metallic) compounds. The removal of mercury to non-detectable levels is vital in ensuring equipment integrity thus reducing the possibility of unscheduled shutdowns and prevent fires. This is because the toxic nature of mercury can poison catalysts used in downstream process units which leads to liquid-metal embrittlement (LME), a type of corrosion leading to crack initiation and propagation primarily in equipment constructed from aluminium.Petro Gasgen’s offering of both regenerative and non-regenerative mercury removal solutions are valuable for both onshore and offshore natural gas streams to help protect and extend the lifecycle of process equipment and downstream piping.

Adsorption Modeling:

Modeling to optimize performance Computer modeling provides information on predicted performance parameters, with bed loading determined by f low and contaminant levels. Optional monitoring around the treatment system envelope can include gas temperature and differential pressure measurement. These measurements are used to confirm anticipated design operating conditions and the impact of changes over time.
