Oil Level Sensors: Monitoring Oil-Water Interface for Separation Efficiency
Overview In the extraction of petroleum (oil) by hydraulic fracturing, oil flows to the well emulsified with fracturing water. As part of the extraction operation, oil and water are separated at the well site. Separation also occurs at the refinery, where crude oil from the well site contains water that must be removed before refining. Separation vessels or separators are used for the process, ...
