Abstract
A method for recycling production salt water comprises receiving production salt water from an oil well. The production salt water is separated into separate streams of salt water and oil. The salt water is pre-heated to a temperature no less than 2 degrees Fahrenheit below the boiling point of the salt water. The pre-heated salt water is transferred to a separation tank, and the heated salt water is separated in the separation tank into steam and salt by boiling water.
Claims20
A method for recycling production salt water, comprising:
- receiving production salt water from an oil well;
- separating the production salt water and oil into separate streams of salt water and oil;
- pre-heating the salt water to a temperature no less than 2 degrees Fahrenheit (° F.) below the boiling point of the salt water;
- transferring the pre-heated salt water to a separation tank;
- and
- separating the heated salt water in the separation tank into steam and salt by boiling the salt water.
A system for recycling production salt water, comprising:
- a salt water inlet valve configured to receive salt water;
- a separation tank configured to receive the salt water from the salt water inlet valve;
- a burner tube located within the separation tank that is configured to pass hot gas through the separation tank and boil the salt water;
- a steam exhaust configured to release steam produced by the separation tank;
- a salt valve configured to release salt produced by the separation tank;
- and
- a control system that is communicatively coupled to the salt water inlet valve and the salt valve,
- wherein the control system is configured to control operations of the salt water inlet valve and the salt valve,
- wherein the control system is configured to open the salt water inlet valve to flow the salt water into the separation tank based on a temperature of the salt water within the separation tank, and
- wherein the control system is configured to periodically open the salt valve to release the salt produced by the separation tank.
A skid-mounted system for recycling production salt water, comprising:
- a skid housing;
- a plurality of separation tanks enclosed within the skid housing;
- a control system enclosed within the skid housing;
- an outer salt water port configured to be connected to a supply of salt water and transfer the salt water to the plurality of separation tanks;
- an outer fuel port configured to be connected to a fuel supply and provide fuel to burners attached to the plurality of separation tanks;
- a plurality of exhaust stacks that are connected to the plurality of separation tanks and that are configured to exhaust hot gas produced by the burners to an environment;
- and
- a plurality of steam stacks that are connected to the plurality of separation tanks and that are configured to release steam produced by the plurality of separation tanks.
