The mass transfer in the gas-liquid system at sulfating of organic raw material

This study considers using of pellicle reactors to be one of the main directions of sulfating technology. In this paper, we address the problem of determining the mass transfer coefficient dependences from temperature, irrigation density, and air-gas stream speed. In addition, we illustrate the research results of physical and chemical properties of sulfated products.

Mathematical model of Thermal Mode Control of Extrusion Process of Polymeric Materials

The paper considers an extruder as an object of mathematical modeling. We address the issue of mathematical modeling of the thermal mode control of extrusion process of polymeric materials. Crucially, we develop a mathematical model, which takes into account basic factors, influencing the increase of work efficiency of the extruder.
