| description | The analysis of the main modern technologies for obtaining low temperatures and liquefying hydrocarbons
using compressor equipment is presented and the most significant results of research in the field of
low-flow compressors based on low-speed, long-stroke piston stages are presented. A method
for calculating an ideal vapor-compression refrigeration cycle is presented, adapted to the object
under consideration, taking into account the possibility of implementing quasi-isothermal compression.
A comparative computational analysis of temperature conditions and thermodynamic efficiency of
a two-stage refrigeration cycle and single-stage refrigeration cycles is carried out during adiabatic
and quasi-isothermal compression processes in the boiling temperature range 278 K ... 198 K. It is
shown that in terms of the discharge temperature and coefficient of performance, a single-stage vaporcompression ammonia refrigeration machine based on a low-speed quasi-isothermal stage is comparable
to a similar two-stage machine based on adiabatic stages. This allows, in relation to actual objects —
small refrigeration machines and installations, to predict both the energy and technical advantages of
using a single-stage scheme based on low-speed, long-stroke piston compressors. In addition, it has
been shown that the effective use of such a compressor is also possible in hydrocarbon liquefaction
systems, while ensuring their safe temperature conditions in a wide range of atmospheric temperatures. |
