Disclosed is a process and apparatus for cooling a coolant used in a heat exchange equipment in a plant. The process is performed in a plant having the apparatus disclosed herein. The process and apparatus utilize a geothermal cooling loop for cooling at least a portion of the total amount of coolant circulating in the coolant loop that is used to cool a surface of a heat exchange equipment in the plant.

A system includes a waste heat recovery heat exchanger configured to heat a heating fluid stream by exchange with a heat source in a crude oil associated gas processing plant; and an Organic Rankine cycle energy conversion system. The Organic Rankine cycle energy conversion system includes a heat exchanger configured to heat a first portion of a working fluid by exchange with the heated heating fluid stream; and a cooling subsystem including one or more cooling elements each configured to cool one or more of a process stream from the crude oil associated gas processing plant and a cooling water stream for ambient air cooling by exchange with a second portion of the working fluid. The Organic Rankine cycle energy conversion system includes an ejector configured to receive the second portion of the working fluid from the cooling subsystem and a third portion of the working fluid; a turbine and a generator configured to generate power by expansion of a fourth portion of the working fluid; and a cooling element configured to cool a stream of working fluid including an output stream of working fluid from the ejector and the expanded fourth portion of the working fluid from the turbine and generator.

A system includes a waste heat recovery heat exchanger configured to heat a heating fluid stream by exchange with a heat source in a crude oil associated gas processing plant; and a modified Goswami energy conversion system. The modified Goswami energy conversion system includes a first group of heat exchangers configured to heat a first portion of a working fluid by exchange with the heated heating fluid stream; and a second group of heat exchangers configured to heat a second portion of the working fluid. The modified Goswami energy conversion system includes a rectifier configured to receive the heated first and second portions of the working fluid and a third portion of the working fluid and to output an overhead discharge stream and a liquid stream, the third portion of the working fluid being at a lower temperature than the heated first and second portions of the working fluid. The modified Goswami energy conversion system includes a cooling subsystem including one or more cooling elements configured to cool a chilling fluid stream by exchange with the overhead discharge stream; and a turbine configured to generate power from the liquid stream of the working fluid.

A system includes a waste heat recovery heat exchanger configured to heat a heating fluid stream by exchange with a heat source in a crude oil associated gas processing plant. The system includes an Organic Rankine cycle energy conversion system including a pump, an energy conversion heat exchanger configured to heat the working fluid by exchange with the heated heating fluid stream, a turbine and a generator configured to generate power by expansion of the heated working fluid, a cooling element configured to cool the expanded working fluid after power generation, and an accumulation tank. The heating fluid flows from the accumulation tank, through the waste heat recovery heat exchanger, through the Organic Rankine cycle energy conversion system, and back to the accumulation tank.

The device comprises: a shell defining an interior volume to receive the first fluid extending along a longitudinal axis; a tube bundle arranged inside the shell, the tube bundle extending longitudinally in the interior volume to receive the second fluid; a disengagement member, able to perform liquid vapor separation in the fluid carried from the interior volume, the disengagement member being arranged above the tube bundle. In at least one plane perpendicular to the longitudinal axis, the disengagement member includes at least two separate fluid passage regions and at least one intermediate region preventing fluid from passing.

A helically coiled heat exchanger with a plurality of inlets each connected to at least one assigned tube defining a heating surface of the heat exchanger and having at least one changeover means to switch the inlet between a first operating state and a second operating state. In the first operating state, a stream of a first medium and, in the second operating state, a stream of a second medium is introduced via the inlet into the assigned tube. In the first operating state more heating surface is available to the stream of the first medium and correspondingly less heating surface is available to the stream of the second medium. In the second operating state more heating surface is available to the stream of the second medium and correspondingly less heating surface is available to the stream of the first medium.

System for cleaning an object, such as a heat exchanger comprising a bundle of feed-through tubes extending between two end plates, wherein the system comprises a connection body for connecting the system to an object, a holder for holding a cleaning device and a moving system for moving the holder with respect to the connection body in a first direction and a second direction at least having a component perpendicular to the first direction, wherein the moving system comprises a rotation motor and a linear motor.

Disclosed are exemplary embodiments of heat exchangers that may be capable of cooling multiple process loops with a single primary or shell-side fluid and/or have combined liquid-to-liquid and liquid-to-air heat exchange capability.

A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.
