Abstract
A method of dewatering a hydrocarbon storage tank carrying a first fluid layer that includes a first hydrogen concentration and a second fluid layer that includes a second hydrogen concentration includes receiving, from a sensor and by a processor communicatively coupled to the sensor, a value representing an amount of backscattered neutrons sensed by the sensor. The sensor is attached to a surface of a wall of the tank adjacent a fluid outlet of the storage tank. The sensor is configured to sense neutrons backscattered from the first fluid layer and an interface layer. The method includes comparing, by the processor, the value to a threshold, and actuating, by the processor, a valve fluidically coupled to the outlet of the storage tank to drain the first fluid layer from the storage tank while preventing the interface layer from leaving the storage tank.
