Heat exchanger are heavily used in the oil and gas industry, refineries, textile, gas plants and many heavy indutries. During use, carbonaceous deposits including heavy oil, bitumen, and other hydrocarbons can form on the tube bundles, reducing the effectiveness of the heat exchanger and forcing the operator to consume more energy to achieve the desired degree of temperature change. Accordingly, in order to maintain an efficient operation of the heat exchanger, it is necessary to periodically remove the fouled tube bundles and clean them of hydrocarbon deposits.
