【Daily Question No. 327】November 29, 2018: What is isothermal compression? During isothermal compression, the temperature of the gas remains constant from intake to exhaust. In the isothermal compression cycle, it is required that the cooling device remove all the heat corresponding to the compression work, so that the intake work equals the exhaust work. Therefore, isothermal compression requires the least amount of compression work, has the highest efficiency, and is the most favorable compression cycle ； However, since the cooling equipment in compressors cannot be that complete, an isothermal compression process cannot be achieved within a compressor. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Keep the temperature constant and continuously reduce the pressure to carry out compression
The gas temperature remains constant during compression
Isothermal compression: When the temperature of a gas remains constant during the compression process, it is called isothermal compression. In an ideal scenario, it can be regarded as a reversible compression process. The engineering solution involves a water-cooling system for the compressor; the high-temperature gas after compression passes through the cooling water, which absorbs the heat generated during compression. During isothermal compression, the entropy of the gas decreases, and this is also the most crucial step in the refrigeration and liquefaction of gases.
