Green Low-Temperature Purification
Hanertech develops and designs melt crystallization process technology, offering customized standalone equipment, integrated skid-mounted units, or on-site installation systems.
Melt crystallization is a method for separating and purifying substances based on their differing melting points, making it an energy-efficient, clean separation process for organic compounds. It demonstrates high efficiency in isolating special systems—such as hydrocarbons with closely matched boiling points, structural isomers, and heat-sensitive materials—while the production of ultra-pure substances stands out as a unique advantage of melt crystallization.
Our approach of static stepwise crystallization is a novel method for separation and purification. By using specially designed crystallization plates and a self-developed temperature-control unit that precisely regulates the medium temperature within the plates, we enable the target substance to gradually transition from a saturated state into an oversaturated one, prompting the desired compound to crystallize and precipitate out—eventually forming a continuous crystalline layer on the plate surface. Meanwhile, melt crystallization yields high-purity products through a three-step process: cooling-induced crystallization, warming-induced sweating, and subsequent heating to achieve complete melting.
