PEI is the leader in mercury chemical decontamination science and has partnered with several
major oil and gas industry leaders to develop effective mercury removal chemistry and implement
chemical decontamination programs. PEI has the experience and technical resources to provide
comprehensive chemical decontamination solutions to our clients world-wide. We have industrial
assets with specialized cleaning equipment and experienced engineers around the globe and
provide holistic processes for mercury decontamination of hydrocarbon processing equipment.
Our team has built upon years of experience and exhaustive research to develop mercury suppression and removal chemistries designed especially for hydrocarbon processing systems. PEI and Eurofins-FGS have developed a field analytical method using GFAA spectrometry that accurately measures the reaction efficiency of our chemical solutions providing almost immediate data to determine chemical residence times.
The incorporation of mercury into metal surfaces, reaction with corrosion layers,
accumulation in sludge and other deposits and the condensation of mercury in equipment
can lead to situations that are hazardous and which may require special procedures and
precautions. In these situations, removal of mercury and mercury compounds from
equipment may be necessary to protect workers, to protect equipment integrity and to
ensure environmental compliance.
For hydrocarbon processing equipment going back into service processing mercury contaminated process streams, the primary purpose of equipment decontamination is to reduce worker exposures to mercury vapor and dermal contact with equipment surfaces during inspection and maintenance activities.
This can be accomplished using either aqueous extraction or precipitative treatments. Aqueous extraction uses aqueous based chemistry with additives that oxidize mercury to a soluble ion or complex that partition to the aqueous phase. Precipitative treatments use various chemical additives to form insoluble mercury compounds.
PEI has formulated custom mercury vapor suppressants for use in the hydrocarbon processing industry. We can formulate vapor suppressants using various carrier matrices (i.e., DI water, glycol, alcohol) and various copper ions and thiosulfate ions. Some formulations may also include sulfur and potassium iodide. Vapor suppressant can be used for short term maintenance and inspection events where entry into closed space atmospheres is limited and exposure risks to personnel are low.
MMS100 is a specially formulated surfactant based chemistry that encapsulates hydrocarbons and metal ions. MMS100 is extremely efficient in reducing LEL and can be used in dilute form in vapor-phase, cascade-phase, foaming, and full circulation environments.
MMS200 is a unique proprietary blend of surfactants and chelants formulated as an aqueous
extractant but with a reactive component as well. For hydrocarbon processing systems
MMS200 is designed to be used in series and conjunction with MMS100. Both chemistries
mixed in solution provide an extremely effective hydrocarbon and mercury removal phase
and can be used in vapor phase, cascade phase, foaming, and full circulation
When planning mercury chemical decontamination projects a critical component of planning is waste minimization. Both MMS100 and MMS200 are formulated with this in mind and are non-toxic, non-flammable, non-corrosive and biodegradable. PEI has successfully removed suspended-particulate, suspended-adsorbed, and soluble mercury and mercury compounds from our chemistries to parts per trillion levels.
