Mobile oil stream energy recovery system

A mobile heat exchanger may include an Organic Rankine Cycle assembly configured to generate the power. A mobile heat exchanger may include a mobile heat exchanger skid in fluid communication with the Organic Rankine Cycle assembly and configured to transfer thermal energy from a high-temperature fluid to a working fluid. The mobile heat exchanger may include a frame having a plurality of extending supports, none of which are arranged in a cleaning volume. The mobile heat exchanger may include a low-pressure heat exchanger arranged adjacent to the cleaning volume facilitating in situ plate cleaning of the low-pressure heat exchanger. The mobile heat exchanger may include at least a first pipe loop and a second pipe loop, both selectively coupled to the low-pressure heat exchanger. The mobile heat exchanger may be arranged on a transportable skid.

Claims preview

1 . A system for generating power, comprising: an Organic Rankine Cycle assembly configured to generate the power; a mobile heat exchanger skid in fluid communication with the Organic Rankine Cycle assembly and configured to transfer thermal energy from a high-temperature fluid to a working fluid, the mobile heat exchanger skid comprising: a frame having a plurality of extending vertical supports supporting a first pipe loop and a second pipe loop, wherein the first pipe loop comprises a first pipe segment and the second pipe loop comprises a second pipe segment; a low-pressure heat exchanger mounted on the frame; a cleaning volume arranged adjacent to the low-pressure heat exchanger; the first pipe loop and the second pipe loop both selectively coupled to the low-pressure heat exchanger; a pump in the second pipe loop; the first pipe loop passes through the low-pressure heat exchanger and is configured to pass the high-temperature fluid through the low-pressure heat exchanger; and the second pipe loop passes through the low-pressure heat exchanger in proximity to the first pipe loop and is configured to (1) bring the working fluid into the low-pressure heat exchanger at a first temperature, (2) remove the working fluid from the low-pressure heat exchanger at a second temperature greater than the first temperature, and (3) provide the working fluid to the Organic Rankine Cycle assembly; wherein the cleaning volume is free of extending vertical supports; and wherein the first pipe segment and the second pipe segment are removably coupled to the low pressure heat exchanger in the cleaning volume to facilitate in situ cleaning of the low-pressure heat exchanger. 2 . The system of claim 1 , wherein the working fluid is an aqueous solution comprising water. 3 . The system of claim 2 , wherein the working fluid is an aqueous solution comprising water and glycol.
