The expansion process of free gas can be regarded as an adiabatic process. When the gas expands, it expands outwards to do work.
It is very difficult to achieve isothermal compression and expansion using conventional compressors and expansion devices as conventional compressors and expanders work at high speed with the nearly adiabatic process. Special types of compressors and expanders are required to achieve isothermal OCAES in reality.
The expression for the temperature growth calculation during the drawing at high speed (for the conditions of the adiabatic process) has been given as following [4]:
The company believes its new 'ACE' Dry Coolers perfect the adiabatic process by combining higher demands for temperature accuracy with innovative technology.
For an adiabatic process, temperature rise can be calculated for given monomer concentrations and the final temperature estimated based on the initial temperature.
Towers can be operated without using the adiabatic process (relying on ambient air to cool the coils) when air temperatures are low.
Concept of adiabatic logic circuits is generated from the adiabatic process which is a thermodynamically reversible process that is operated slowly, so that total energy dissipation tends towards zero.
Maintaining constant enthalpy increases even more its performance, resulting in benefits such as: (1) desired product moisture content is reached in a faster way, because larger space and time increments may be used, with no interference in the quality of the final results; (2) no distortions should occur in the heat and mass balances between the product and drying air, once drying is conducted as the well accepted adiabatic process.
where [[rho].sub.0] is working fluid density in the evaporation zone; k is exponent of adiabatic process.
