METHOD AND SYSTEM FOR PURIFYING PRODUCED WATER

摘要

A method and system of cleaning or purifying produced water, especially from a well head, using a humidification/dehumidification unit comprised of at least one humidification chamber portion capable of receiving hot produced water and, in a counter current direction, air; and at least one dehumidification/condensation chamber portion capable of receiving humid air from the humidification chamber portion. Concentrated produced water is capable of being withdrawn from the humidification chamber portion, and clean or purified water is capable of being withdrawn from the dehumidification/condensation chamber portion.

主权项

1. A method of purifying produced water, including the steps of:
providing produced water that is at a temperature of from 140 to 212° F.; conveying the hot water through at least one humidification chamber portion; conveying ambient air through the at least one humidification chamber portion countercurrent to the direction of conveyance of the hot water therethrough to produce an 99% humid atmosphere in the at least one humidification chamber portion, wherein concentrated produced water is also produced in the at least one humidification chamber portion; withdrawing the concentrated produced water from the at least one humidification chamber portion; conveying the humid air of the up to 99% humid atmosphere to at least one dehumidification/condensation chamber portion; allowing the humid air to cool in the at least one dehumidification/condensation chamber portion, wherein fresh water is condensed out; and collecting the fresh water.
