Abstract:
The article examines the environmental aspects of creating turbo-compressor units for compressor stations of main gas pipelines. The aim of the study is to identify and analyze the main sources of environmental pollution arising from the operation of turbo-compressor units, as well as to analyze modern technical solutions aimed at reducing their negative impact on the environment. This goal is achieved through an analysis of the operational processes of turbo-compressor units, a review of literature sources and applicable regulations, as well as the systematization of many years of experience

An air conditioning system using water as refrigerant (R718) that compresses water vapor with multistage stage variable speed axial compressor with intercooling between stages by water injection is considered. Four stage compression with flash intercooling resulted in 50% improvement of coefficient of performance (COP) at full load compared to conventional refrigerants like R134a. The energy efficiency of an air conditioning unit is specified by seasonal energy efficiency ratio (SEER).

Abstract:
In the practice of centrifugal compressor designing, different engineering techniques are widely used because flow motion differential equations cannot be integrated, and Computational fluid dynamics cannot resolve the problem as a whole. Engineering personal computers’ programs are based on experimental data and the gas dynamics theory. The universal modeling method’s (UMM) mathematical model is a set of equations that determine the pressure loss in the elements of the centrifugal compressor flow path. By the earlier versions of the UMM, dozens of process compressors were designed. Several se

The objective of this study is to identify the sources of acoustic noise (noise pollution) in the Noor-Abad gas compressor station and then to prioritize the station equipment based on noise pollution. First, the key locations inside the station as well as in the surrounding residential area, aka the study area, are determined for the measurement of sound pressure level. Then, the sound pressure level is measured at those points, and the related noise map is produced. Based on the noise map, the noise condition in the study area is evaluated by comparing the measured acoustic parameters with a

Abstract:
Natural gas is transported through a network of main gas pipelines under high pressure, and the process of its consumption requires a decrease in pressure of gas laid mainly in throttling devices. It is beneficial to use part of the available energy potential of natural gas for electricity production by means of expander-generator technologies. However, the task of finding ways to increase the capacity and efficiency of gas turbine power units using the energy of excess pressure of natural gas does not lose its relevance.

Abstract:
The paper provides a theoretical analysis of the operational performance of a marine two-stroke diesel engine in a wide range of modes, operating on a helical characteristic. Reducing the diesel load causes a decrease in the coefficient of excess air for combustion, which is characteristic of two-stroke diesel engines with a relatively high boost pressure. To control the air flow rate, it is proposed to use an adjustable nozzle apparatus as part of a turbine of a turbocharger unit. Changing the angle of the blades of an adjustable nozzle apparatus by turning them, an impact was made on the cha

The article is devoted to the generally recognized dilemma of using secondary energy resources in the transportation and distribution of natural gas. At stations where throttle devices are used, excessive gas pressure as the main component of secondary energy resources for technological processes is practically not used. Currently, the replacement of throttle devices with turbo-expander units is determined by energy and economic efficiency. This is due to the fact that the use of excess gas pressure in the turbo expander both at gas distribution stations and at compressor stations of gas pipel

This paper discusses how to determine the arrangement of compressors in a two-unit gas pipeline station where there is no standby unit. The compressors are driven by variable speed drivers such as gas turbines or variable frequency electric motors. Both series and parallel arrangements are analyzed in a transient simulation mode to determine which operation mode is more advantageous. Among the assumptions in this paper are the performance characteristics of the compressor. It will be outlined how these performance characteristics influence the conclusions.

Arranging compressor units in series rather than in parallel can offer a number of advantages in many applications. However, especially if the compression ratio is rather high, it is desirable to use different impellers for the low-pressure and the high-pressure compressor. Otherwise, one or both operate off their best efficiency points. This leaves however the problem of the staging of a spare unit. In the paper, a solution to this dilemma is described.

The drawback of electrically driven vapour compression cycle is their dependence on an electrical grid and the fact that they increase the winter or summer electricity peak demands. Hence, a thermally driven vapour compression cycle would offer substantial advantages and flexibility to the end user for heating and cool

Abstract:
Compression systems are designed and operated in a manner to eliminate or minimize the potential for surge, which is a dynamic instability that is very detrimental to the integrity of the compressor unit. Compressor surge can occur when compressors are subjected to rapid transients such as those occurring following an emergency shutdown (ESD) or a power failure, which in turn, requires fast reaction. To prevent this from occurring, compressor stations are designed with single or dual recycle systems with recycle valves, which are required to open upon ESD. There has been extensive debate and c
