    K°Bloc supports continuous operation for Indian PVC manufacturer. Replacing three shell and tube heat exchangers with the Kelvion K°Bloc has enabled Finolex Industries to operate its heat recovery application continuously. Finolex Industries Limited is the largest manufacturer of PVC pipes in India and it is also recognized as one of the largest manufacturers of PVC resin in India. Their manufacturing plants in Pune, Ratnagiri, and Masar house are all the modern-day equipment that help to churn out an impressive 370,000 Mio. tons per annum. Finolex PVC Pipes and Fittings are available in various sizes, pressure classes and diameters making them suitable for diversified applications in both agricultural as well as non-agricultural sectors including housing, industrial and construction.

    The challenge

    Finolex Industries, manufacturing PVC pipes and fittings, runs a recycle EDC chlorination feed product interchanger, which also recovers waste heat. The three shell and tube heat exchangers used in the process needed to be cleaned regularly to remove coke particles that were clogging the tubes, which were also prone to leaks.

    This led to frequent shut downs, disrupting the smooth operation. Also the units were heavy, difficult to maintain and took up a lot of space.

    The solution …
    was to replace the units with one K°Bloc welded plate heat exchanger. This is lighter and more compact than conventional shell and tube heat exchangers. It also has self-cleaning properties due to high shear forces on the heat transfer surface that prevent fouling and choking of the tubes. Therefore it is much easier to maintain.

    The result
    Since the K°Bloc was installed three years ago, it has been operating successfully. Finolex Industries reports that the unit has only needed cleaning once as part of an annual shut down.

    The company said: “We also saved a lot on space and foundation due to the compactness of K°Bloc and recovered the price of the unit within a year.”

    “WE [...] SAVED A LOT ON SPACE AND FOUNDATION DUE TO THE COMPACTNESS OF K°BLOC AND RECOVERED THE PRICE OF THE UNIT WITHIN A YEAR."
