Additional Industrial Applications

Printing Ink Compound

Scraped Surface Heat Exchangers are cooling and crystallizing these products at many plants. Most commonly, polyethylene wax beads are dissolved in a hot carrier like linseed oil, varnish, or other solvent and then rapidly cooled. The wax crystallizes in numerous very fine particles, trapping the liquid carrier in a soft paste. These products are blended with inks for high-speed printing presses, serving as an anti-smear agent where particle size is critical for best print quality.

Pelletizing

Many chemical and polymer products solidify on cooling from high reaction temperatures. The shape and size of the particles depend on the final cooling system employed - a flaking roll, a belt cooler, or an underwater pelletizer are a few possibilities. A Ftherm® X unit can easily pre-cool even very viscous resins to near the melting point, so that the final cooling system can operate at maximum capacity.

Chemical Reactions

Scraped Surface Heat Exchangers are ideal for carrying out fast chemical reactions in a one-pass, continuous system when reactants are viscous or immiscible. Examples include sulfonation and nitration of organic compounds. Vigorous agitation produces a fine dispersion of the reactants for maximum reaction rate, increased yield, and fewer side reactions. For reactions that proceed more slowly, likesome polymerizations, the Ftherm® X unit can be employed as a side-arm heat exchanger while reactants are recirculated around a batch reactor vessel.

Grease

Ftherm® X SSHEs provides an early process for continuous production of high quality lithium and aluminum complex lubricating greases. Modern batch and continuous grease processes have improved since then, but the Ftherm® X remains the best way to cool the grease before packaging. It can crystallize the solid-phase ingredients without fouling on the heat transfer surface, and the uniform treatment ensures a product with consistent physical properties.
