Business concerns continue to devise means for minimal energy utilization due to rising energy cost, environment concerns, and the need to maximise profit. For systems designed during the era of cheap energy, retrofitting becomes a viable option. This research applies heat integration techniques to monitored industrial plant data of a functional refinery to retrofit the preheat section of the …

A systematic experimental investigation was conducted to evaluate the heat Transfer characteristics of a copper-nickel multi tube with corrugated copper fins in a cross flow heat exchanger. The heat transfer rate from a tube can be augmented either by increasing the surface area, by number of fins or by creating turbulence in the flow. Experiment was carried out under the copper fin tube type h…

Analysis to measure the condensation heat transfer coefficient and the pressure drop in brazed plate heat exchangers (BPHEs) were conducted with the refrigerants R134a. Brazed plate heat exchangers with different chevron angles of 45o, 35o, and 20o were used. Changing the mass flux, the condensation temperature, and the vapour quality of the refrigerant, the condensation heat transfer coeffici…

The latest generations of micro-scale systems are becoming more challenging to fit into designs. These chips are squeezing into smaller and smaller spaces with very little place for heat to escape. Therefore, MEMS heat exchanger has become popular in many practical applications although improvement of heat transfer characteristics is a key issue for the users as well as researchers. In the pres…

China is one of the largest glyphosate producers in the world. The production process consumes a large amount of energy and discharges a huge volume of wastewater. In the glyphosate production system, the byproduct recovery process consumes the largest amount of energy. To conserve energy consumption and minimize wastewater discharge, the study applies pinch technology to optimize the he…
