This article describes the features and operation principle of the fifth generation gas cylinder equipment, as well as its advantages and disadvantages.

From the equation of the efficiency of the boiler unit, the main directions for increasing the efficiency of the heat source were determined. A classification of measures to increase the efficiency factor is given. An analysis of measures to reduce heat losses is given. Schemes with the use of renewable energy resources and heat utilizers are considered. Based on the analysis, the simplest scheme for increasing the efficiency of the boiler was chosen.

In recent years, there has been a growing interest in environmental building materials in the oil and gas industry, which contribute to improving the sustainability, safety and efficiency of construction processes. This article examines modern developments in the field of ecological building materials, their properties, advantages and impact on the environment.

The effectiveness of a method for increasing the rate of mass transfer(determining factor in formation of hydrate, utilizing of harmful gases, melts degassing) of gas in a liquid based on the formation of waves on the surface of stable gas bubbles in a liquid during the collapse of cavitation bubbles created by ultrasound has been theoretically substantiated. The three-dimensional numerical model of wave formation on the surface of stable gas bubbles is proposed, which makes it possible to estimate the increase in the interfacial surface area depending on the ultrasonic exposure modes. An assessment of the modes and conditions allowing to achieve the maximum possible increase in the interfacial surface using the ultrasonic method has been performed.
