Problems and Solutions in the Steam Vacuuming System of Atmospheric and Vacuum Distillation Units
If the vacuum level in the vacuum distillation tower is insufficient, the possible causes include: insufficient steam pressure, clogged ejectors, an excessive amount of light components in the tower, too high a steam supply at the bottom of the tower; and, in the most severe cases, leaks
Problems: 1. High energy consumption due to the use of steam; 2. Fluctuations in steam pressure, which can affect the vacuuming process; 3. Insufficient vacuum level. Solutions: 1. Add another vacuum pump (mechanical vacuum pump) to replace the secondary steam-based vacuuming system; 2. Use a larger vacuum pump, which can reduce the steam pressure used for vacuuming from medium-pressure steam (13 kg) to low-pressure steam (8 kg), thereby saving steam
