Benefits of technology
This patent is about a better way to heat frac fluid and other fluids in a more efficient way. The method involves using a primary heater to heat the fluid and an auxiliary heater to further heat the fluid. Another heat exchanger is added to enhance the heat content of the fluid returning from the primary heater. This results in much better heating efficiency of the fluid and can be incorporated without adding significant mass or space to the overall heating arrangement. The heating arrangement can be easily transported to a worksite and remotely controlled, reducing the need for manual visits. Overall, this technology allows for much more efficient heating of fluids.
Problems solved by technology
Although this is generally useful, it appears to be quite cumbersome not only from a handling point of view, but also for positioning about the tank.
It is well known that holding tanks or reservoirs are very large and it would be somewhat cumbersome to wrap the blanket about a large vessel.
It is well established that such arrangements have limited efficiency.
As with the previous reference, this reference is confined to a relatively inefficient heating means in terms of the coil type arrangement.
The arrangement is fairly complex and does not indicate any thermal energy augmenting system which would elevate the efficiency of the unit.

Embodiment Construction
[0047]Referring now to FIG. 1, schematically depicted is the overall apparatus employed as an example. The overall arrangement is denoted by numeral 10. A reservoir 12 retains a fluid, one example of which is fracturing fluid, commonly referred to as “frac” fluid. Such vessels typically include a liner 14 which secured to the reservoir by, for example, clamps or other suitable fasteners 16 (not shown). As is well known to those skilled in the art, frac fluid needs to be maintained at an elevated temperature in order to be useful. This requires the injection of heat into the fluid.
[0048]Heat injection in the example is achieved by making use of a modular heating station, generally denoted by numeral 18. With the instant technology, the station 18, is particularly effective since it is retained on a skid 20 which may be easily transported to a worksite and disengaged from a truck for use. This has the advantage of preventing the invasiveness of several trucks at the site for prolonged...

An apparatus and method for enhancing the transfer of heat in a fluid within a reservoir. The interposition of heat exchangers between a primary heating arrangement and an auxiliary heating arrangement results in greater utilization efficiency in heat transfer to the fluid within the container. A predetermined arrangement of heat exchangers within the reservoir containing the same is also disclosed.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a method of enhancing the efficiency of heat transfer into a liquid fluid container and more particularly, the present invention relates to a method, system and apparatus for efficiently transferring heat into a fluid requiring the maintenance of a certain temperature in order to have the fluid remain effective.BACKGROUND OF THE INVENTION[0002]Fluid heating arrangements have been known for many years and these permeate a wide variety of industries. One industry where the temperature maintenance of the fluid is important is in the fracturing fluid heating industry. As is known “frac” fluid requires heating in order to be effective in an oil field operation. The temperature of the frac fluid must be maintained at certain temperatures in order to prevent fallout of sand within the fracturing environment.[0003]A panoply of methods and different apparatuses to effect the method have been proposed in the prior art. An example of...
