ABSTRACT:
An apparatus and method for heating transporting and heating a liquid for treating oil and gas wells and pipeline systems is provided. The apparatus includes a vehicle having an engine and a tank for transporting a liquid that can be used for treating oil wells or pipeline systems is connected to move with the vehicle. A heat exchanger system is operatively connected to the engine. A selectively operable circulating pump and a circulating line are operatively connected between said tank and said heat exchanger system for circulating the liquid from the tank through the heat exchanger system to heat the liquid. The apparatus includes at least one selectively operable valve for controlling the flow of liquid through the circulating pump, the circulating line, and the heat exchanger system. Liquid is pumped through the heat exchanger system to use heat energy from the engine to heat the liquid to a predetermined temperature prior to use for treating an oil well or pipeline system. The method includes the steps of: loading a tank on a truck with a treatment liquid; driving the truck to a remote site; while the engine is running, circulating the treatment liquid through a heat exchange system that is operatively connected to the engine of the vehicle, thereby heating the liquid to a predetermined temperature; and then discharging the heated liquid into an oil and gas well or pipeline system.
