Continuous reforming

This post was last edited by Chongzheng Xiaobing on 2017-8-6 at 08:59. The vacuuming of the extraction solvent system is carried out at the top of the solvent recovery reflux tank; the unit is equipped with a 1.0MPA steam evacuator. Operation of the vacuum extractor: 1. First, check the liquid level in the steam condensate tank; keep the level at around 50%. Drain excess liquid when the level is high, and add water when it is low ； 2. After the liquid level in the condensate tank stabilizes, activate the 1.0MPA steam-water cooler ； Direct 1.0 MPA steam to the valve inlet, where there is a low-point drain; open this drain to remove all condensate from the steam pipeline and prevent liquid slugging ； 3. After draining completely, inform the operator inside to open the relevant valves and start the vacuum pump. The operator should monitor the pressure of the vacuum pump; once a negative pressure is established, initiate the vacuuming process in the solvent recovery tank’s reflux vessel, keeping an eye on the negative pressure level. It’s my first time answering questions; please point out any mistakes! ! !

Aren’t aromatic extraction solvent regeneration towers generally equipped with dry vacuum pumps?
