Use advice for data set When utilizing the Life Cycle Assessment data for the in-situ Multiphase Extraction process, it is essential to incorporate the operational duration of the MPE system, which is conservatively estimated at 15 years. Note the requirement for replacement of some components within this timeframe. It's crucial to account for all primary raw materials and the essential energy consumption in the input-output flow calculations. The functional unit for this data set is the removal of an estimated 80% of contaminants from approximately 40,000 cubic meters of subsurface soil, which should be factored into the overall assessment.

Data set use approval

General comment In-situ Multiphase Extraction (MPE) is a remediation technology that extracts soil vapor, non-aqueous phase liquids and groundwater simultaneously. The vacuum extraction allows liquid flow rates to be increased around the extraction well, due to the increased pressure gradient from the groundwater being drawn downward. Lowering the pressure around the well in the subsurface also allows the non-aqueous phase liquid to volatilize more easily. The volatilized contaminants are removed from the subsurface via extraction wells. The extracted soil vapor, non-aqueous phase liquids and groundwater are treated on the surface via gas and liquid treatment trains.

Technical purpose The technical usage of the described industrial process is primarily for in-situ soil remediation. Specifically, the multiphase extraction method is applied to contaminated land areas. It serves to effectively extract contaminant masses, such as soil vapor and non-aqueous phase liquids, from a large volume of subsurface soil, thereby returning the land to a non-hazardous state suitable for future use or redevelopment.
