Abstract
The present disclosure relates to water purification. The teachings thereof may be embodied in processes for removing contaminants from contaminated water. An example process may include: boiling or evaporating a contaminated water to distill the contaminated water; removing a vapor stream from the boiling or evaporating contaminated water; delivering the vapor stream to an oxidation unit; removing additional contaminants from the vapor stream in the oxidation unit; and discharging a purified water stream from the oxidation unit.
Claims10
A process for removing contaminants from contaminated water, the process comprising:
- boiling or evaporating a contaminated water to distill the contaminated water;
- removing a vapor stream from the boiling or evaporating contaminated water;
- delivering the vapor stream to an oxidation unit;
- removing additional contaminants from the vapor stream in the oxidation unit;
- discharging a purified water stream from the oxidation unit;
- exchanging heat from the purified water stream leaving the oxidation unit to the removed vapor stream before the removed vapor stream enters the oxidation unit.
A process for hydraulic fracturing, the process comprising:
- stimulating production of a hydrocarbon well by injecting a fracking fluid into a wellbore;
- recovering a stream of fluid from the wellbore;
- supplying heat to the fluid to distill the fluid by boiling;
- removing a vapor stream from the boiling fluid;
- adding air to the vapor stream;
- delivering the vapor stream to an oxidation unit;
- removing contaminants from the vapor stream in the oxidation unit;
- discharging a purified water stream from the oxidation unit;
- and
- exchanging heat from the purified water stream leaving the oxidation unit to the removed vapor stream before the removed vapor stream enters the oxidation unit.
