Incinerator system for on-site completion fluid removal and methods of using the same

A method of evaporating a completion fluid, the method comprising:

• receiving the completion fluid through a fluid inlet and into an evaporation cavity of an evaporator tank, the evaporator tank comprising a steam vent;
• heating the completion fluid in the evaporation cavity using a heating assembly comprising a plurality of heating rods disposed in the evaporation cavity of the evaporator tank and configured to move independently in a lateral direction within the evaporation cavity, thereby evaporating at least a portion of the completion fluid such that evaporated completion fluid escapes the evaporator tank through the steam vent, wherein the heating assembly is communicatively coupled to a programmable logic controller;
• measuring at least one fluid property of the completion fluid disposed in the evaporation cavity using a sensor system comprising a plurality of sensors communicatively coupled to the programmable logic controller;
• and
• translating a position of at least one of the plurality of heating rods laterally within the evaporation cavity, and independently of other ones of the heating rods disposed in the evaporation cavity, based on a fluid property measurement of the plurality of sensors thereby altering a localized temperature within the evaporation cavity.
