May I ask how the boiling of towers is carried out during the maintenance of chemical plants?
Thread Content
Our company needs to carry out major repairs, but the environmental regulations here are very strict. If we use a distillation tower, it will cause odors to appear in the air. How can we use such a tower? And how can we recycle the waste gases and wastewater generated by it?
Steam is supplied at the bottom, while venting is done at the top. If environmental regulations are strict, it is possible to reduce the power consumption; then, the liquid in the venting separator tank can be drained into the drain. At the bottom of the tower, a condensate release valve can be used to discharge the liquid into the drain as well!
Clean the oil residues first before proceeding with the treatment.

In our country’s approach, it is necessary to inform the **relevant departments and nearby enterprises about the operating hours, the potential hazards that may arise, the control measures to be taken to address those hazards, as well as the contact details in case of any issues. Generally, emissions at the boiling points are not monitored, but **intervention will take place if complaints come in from nearby areas**. -
Condensation is used at the bottom for exhaust gas absorption and treatment. Eliminate leaks.
First, deodorize and passivate; apply steam at the bottom and vent at the top. If odor persists, connect a temporary pipeline to the flare
Before boiling the tower, the material inside it must be thoroughly rinsed clean first. Select the substance to be used for the first tower washing based on the properties of the material. If the material is soluble in water, boiler water can be used to heat it and then use it for flushing the tower; samples of the flushing water should be taken for analysis during this process. Once the concentration of the material in the water is within acceptable limits, steam can be used to clean the tower. The rinse water is discharged to a wastewater treatment plant for treatment.
