Problems with sulfur-containing wastewater filters in coking units
Thread Content
Which of you has used backwash filters for sulfur-containing wastewater, and what were the results? Where does the medium used for backwashing go? What size of equipment is used, and what is the maximum amount that can be received? How does the filter handle the increased flow during the modification and venting period? Where is the installation location? What are the things to keep in mind?
We use automatic backwashing, and it works very well.
How do you use them, one in use and one as a backup? What is the maximum amount per hour? Is there a lot of coke dust?
There is only one unit, with no spare ones; it is used for intermittent operation, so one can simply ask the manufacturer to produce it according to the actual processing requirements.
Bro Yu, are your filters used in the reflux drum at the top of the distillation tower? My previous refinery only needed to install two line filters at the pump outlet
It is very necessary to install this, as without it, the sulfuric acid vapor stripping tower can easily get clogged by coke dust, which affects the separation efficiency
