METHODS, SYSTEMS, AND APPARATUS FOR DISPOSAL OF OILFIELD WASTE WATER

摘要

Systems and methods for disposing of produced water as steam released into the atmosphere. After wastewater is prepared for disposal by suitable filtering and/or treatment, it flows into a preheating tank where it is heated prior to disposal by liquid filled preheating coils extending from the heating tank which are heated by burner boxes. From the preheating tank, the preheated water flows into evaporation coils, where it is heated above boiling and released as steam. Water flowing into the tank passes adjacent the evaporation and preheating coils near the burner boxes. The preheating coils may contain antifreeze which can be circulated to prevent freezing of the preheat tank when not in use or to maintain the temperature of the preheat tank. The system may be moved with the preheat tank filled with preheated water to facilitate the use another location.

主权项

1. A system for disposing of produced water as steam released into the atmosphere, comprising:
a tank for preheating water; a burn area comprising one or more burn units adjacent the tank; at least a first set of preheating coils comprising tubing that having a coiled portion disposed inside the tank and a coiled portion disposed outside the tank and over at least one burn unit in the burner area; at least a first set of evaporation coils comprising tubing in communication with an intake for receiving preheated water in the tank for preheating water, the at least a first set of evaporation coils having a coiled portion disposed outside the tank and over at least one burn unit in the burner area and an open end for the release of the water as steam; and an incoming water line for passing produced water into the tank for preheating water, the incoming water line running from a source of produced water to a discharge point in the tank with a series of windings adjacent the at least a first set of preheating coils and at least a first set of evaporation coils over the burn area.
