Recently, I’ve been designing a process flow. It involves a large amount of phenol distillation processes. Continuous distillation at such high temperatures requires a great deal of energy. Therefore, I thought of steam compressors. Now, I think the ideal operating condition is that at the inlet of the steam compressor, the temperature of the phenol vapor should be 150–160°C. The pressure is 50-60 Kpa (gauge pressure), and this vacuum is created by the suction force of the steam compressor. Ideally, the outlet pressure of a steam compressor can reach 200–300 KPa (absolute pressure); at this pressure, the material will liquefy and its temperature will rise. The material heated to a higher temperature can be used to warm the material inside the distillation vessel. The steam volume is approximately 15 T/h. My question is whether it is easy to select a steam compressor that meets these requirements; are rotary or centrifugal compressors more commonly used? . 2. I would like to estimate how much the temperature of the material will rise under this pressure, as well as what the liquefaction ratio is approximately. Because it involves phase change heat and gas compression. It seems to be quite complicated when calculated.
If it has been liquefied, don’t use a compressor; as for why, it’s unclear. Seems to be the case.
Moreover, heating is generally done using steam, as steam has a high latent heat of vaporization and a high heat release coefficient.
