Theoretical Foundations of Chemical Technology Laboratory

• The laboratory was established in 1945 on the initiative of Academicians N.M. Zhavoronkov and I.V. Kurchatov to solve scientific and practical problems of separating mixtures in the chemical and related industries.
• Development of physicochemical foundations for the intensification of heat and mass transfer processes in chemical technology, development of physical and chemical methods for their intensification.
• Energy-efficient hybrid separation processes of component mixtures based on rectification, extraction, and crystallization.
• Development of “smart” extraction systems for chemical-technological processes of extraction and separation components of liquid mixtures.
• Development of environmentally friendly two-phase aqueous extraction systems for pharmaceuticals, food processing, and biotechnology.
• Development of highly efficient and non-pollutant extraction methods for the disposal of industrial waste.
• Water purification using chemical and physical methods of intensification.

A model of high-intensity mass transfer in a dispersed-ring flow of liquid and gas (vapor) and a method for calculating film columns with a downward flow of phases were created. The results were implemented in the industry.

The mechanism was revealed, and the Marangoni theory of diffusion-thermal instability was constructed. The connection with the intensification of industrial processes was demonstrated.

The environmentally safe extraction stages for the processing of leaching solutions in the course of battery recycling were developed.

Extraction methods to produce organic acids from liquid industrial wastes (for example, caprolactam production wastes, fermentation solutions, etc.), were developed, creating the prerequisites for the development of innovative technologies, import substitution, and increased environmental safety in the field of mixture separation processes.

Methods to calculate a number of new hybrid processes based on distillation and crystallization from the melt were developed.

An extraction method to obtain metal oxide particles of various shapes of nano- and micrometer size at the interface in two-phase aqueous systems was developed.

A scientifically based method to calculate extractive distillation was created, taking into account the real kinetics of mass transfer in a liquid film flowing down the nozzle.

The optimal schemes for the technological implementation of the processes of ultrasonic excitation of nonlinear flows were compiled, significantly increasing the extraction efficiency and creating a unique situation of isolating the liquid from contact with the external equipment.
