Control System for the Process of Storing Liquefied Petroleum Gas in an Isothermal Tank Within the Range of Fireproof and Explosionproof Operating Parameters

Abstract: The technology of isothermal storage of liquefied hydrocarbon gas (LPG) is proposed, which provides automatic control of the processes of steam condensation in an isothermal tank and regasification of LPG using a steam compression heat pump. The specified storage temperature of LPG is stabilized in the evaporator of the pump, and regasification of LPG with subsequent supply of the gaseous phase to the consumer is implemented in the condenser. The proposed technology allows to ensure accuracy and reliability of process control by reducing the spread of controlled parameters, ensuring their variation in a specified range. This is a significant reserve for intensification of thermal processes with a reduction of fire risk value and improvement of environmental safety, including due to the use of a harmless, noncombustible, explosionproof coolant. The optimal conditions are provided for storage and discharge of gas in large capacity tanks with minimum energy costs.

Nanostructured Pb(S, O) Films: Synthesis, Mechanism of Deposition, and Optical Properties

Abstract: Chemical deposition is used to obtain thin solid films of lead sulfide Pb(S, O) with oxygen contents of 0.2 to 30.7 at %, regulated by a variety of ligands. The oxygen effect on the mechanism of formation and optical properties of Pb(S, O) films is studied experimentally and through quantum-chemical modeling. A heterostructured nature of the synthesized Pb(S, O) compounds is shown for the first time, and a mechanism of their formation in an aqueous solution is proposed.

Study of physical and mechanical properties and combustibility of filled acrylate compositions

Abstract: Compositions based on cross-linked acrylate copolymers and bentonites were obtained. Physical-mechanical and absorption characteristics of bentonite-polymeric composite materials were studied. The effect of a filling agent on the final product properties was demonstrated. The possibility of using these compositions for creating materials with reduced combustibility was shown.
