    Rectification apparatus

    Distillation columns are widely used in various technological processes such as distillation, extractive distillation, liquid extraction and steam-liquid heat exchange. This principle of operation of a distillation column is used both in simple laboratory instruments and in complex industrial installations in oil refining, petrochemical, chemical, gas and other industries. A rectification apparatus is used to separate liquid mixtures into fractions with different boiling points and obtain a stable composition of the output product. Inside the column, multiple contacts of steam and liquid occur on plates or a nozzle, thereby achieving a high degree of purification and minimal loss of useful components. The design is selected according to the environmental parameters, pressure and actual performance of the installation. Rectification columns can be ordered both for a new project and for updating an already operating workshop. Such equipment produces stable product quality, really saves energy and allows you to clearly control each stage of the process. Essentially, this is a transition to more controlled and cost-effective production. You can order a rectification machine in Tashkent from the Thermoflow brand right now by calling us at our numbers.

    Product Advantages

    The distillation process engineering guarantees a product with a purity of up to 99.9%. Highly accurate temperature profile maintenance throughout the column prevents impurities from entering the target fraction. Vacuum distillation technology solutions allow for the processing of heat-sensitive substances, ensuring the preservation of their properties.

    FAQ

    What is the difference between rectification and simple distillation?

    Retrieval separates a mixture into virtually pure components through repeated exchanges between steam and liquid. This is necessary for producing high-quality alcohol, gasoline, or purifying solvents. In ASMEX PETROCHEM apparatuses, this process is automated, ensuring a stable yield of a product of a given concentration.

    How does automation affect the energy consumption of a distillation column?

    The control system maintains a precise ratio of the returned reflux ratio to the recovered product. This allows for the use of precisely the amount of heat required for phase separation. Optimizing heat flows reduces steam or electricity costs by 15–20%, which is critical for the profitability of chemical production in Uzbekistan.

    Can one apparatus be used for different types of feedstock?

    Yes, provided the internal trays and control system are properly designed. Our apparatuses can be reconfigured to handle different fractions by adjusting the temperature and pressure conditions. This makes the equipment a universal tool for small and medium-sized petrochemical enterprises working with a variable product range.
