  • The Major Components of Heat Exchangers

    Heat exchangers are not only one of the most common pieces of equipment found on industrial sites, they are also one of the most important. Despite the name, heat exchangers are used for both heating and cooling and are actually used more often for cooling, especially on industrial sites such as refineries or processing plants. These pieces of equipment are not “one size fits all.” In ...

  • Case study - Heat exchanger retrofit

    Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; ...

  • Monitoring Leaks from Heat Exchanger - Paper Plant

    The Situation A Paper plant in the Eastern US uses 500 GPM filtered pond water for cooling lubricating oil in their paper line.  The now warmer water is sewer to an on-site pond.  Because the water is used to cool lubricating oil, the plant could not reuse the water in their pulping process for fears of possible oil contamination of the paper pulp.  The plant needed to be ...

  • Improving and maintaining the performance of your Heat Exchanger or Condenser.

    The usage of Heat Exchangers or Condensers is common in many processes across a wide range of industries. The Energy sector is no different, either in the Thermal Power Generation, Upstream and Downstream of the Oil and Gas including Petrochemical and Chemical plants; Heat Exchangers are used to cool of the steam or to pre-heat different liquid needed in the processes. The recurrent problem of ...

  • Thermal analysis of smart fins in a micro heat exchanger

    Micro heat exchangers using smart fins undergo variation of temperature along the passage of fluid flow. This requires analysis of these smart cantilevers under thermal load. In the present research, thermal analysis of bi-metallic smart, surface mounted, piezo patched cantilevers under thermal excitation, has been carried out. Electro-thermo-elastic governing equations and constitutive equations ...

  • Monitoring leaks in Heat exchangers - Case study

    The Situation A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Vivianite Heat Exchanger removal trial case study

    On the vivianite-laden heat exchangers, the maintenance supervisor created a recirculation circuit and diluted JS 9325 to a fifty percent (50%) solution. They recirculated the diluted solution for 48 hours while raising the temperature of the solution to 110F. Upon opening the first heat exchanger, they observed a purple solution following by a half-inch (½”) sheet of vivianite ...

  • Design and analysis of concentric tube heat exchanger using entropy generation minimisation

    In a heat exchanger, the amount of heat that is transferred at relatively high temperature is of greater importance than heat balance. This would ensure the conservation of exergy. The entropy generation is the only quantity that quantifies the loss in the exergy. In the present study the entropy generation in concentric tube heat exchanger, and the effect of geometry and working parameters on ...

  • Implementation of a transient exergy analysis for a plate–fin heat exchanger

    A 2nd law thermodynamic analysis with exergy analysis can provide a more robust means of accounting for all of the energy flows within and in between subsystems and the work potential. These energy flows may be thermal, chemical, electrical, pneumatic, etc. Some systems such as air or ground vehicles have very transient modes of operation. Energy optimisation of these vehicles through modelling ...

  • Global Heat Exchanger Market Trends and Opportunities 2014-2019

    Heat Exchangers are used to transfer heat between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. Heat Exchangers are an integral part of many businesses which includes industries, buildings, power generation and transport. The market for heat exchangers has been segmented on the basis of ...


  • We`ll never rod another heat exchanger again case study

    A California gas plant was experiencing heavy scale deposits in its entire plant cooling system. RYDLYME approach 6,600 gallons of RYDLYME was recommended for the 33,000-gallon system. Due to the large volume of water and low concentration of RYDLYME (20%), the system was divided into three isolated loops with each loop circulated with the solution for at ...

  • Refrigerator condenser (shell and tube heat exchanger) cleaning case study

    In today's industrial environment of unceasingly consummates and improvement of equipment manufacturing technologies, heat-exchange and water circulation equipments become popular in the manufacture industry. The equipments can run efficiently at rated power if their systems have clean and unimpeded water channel. Once the water running equipments or systems were blocked by scale, it may cause ...
