It depends on the situation; in most cases, it involves solid products. There are various methods for dealing with this – one approach is to mix them into a slurry, send it out, and then separate it. For this type of process, special attention must be paid to proper drainage and cleaning procedures, as the system is prone to clogging; Another type is the tubular reactor used in fertilizers, where the slurry is directly granulated after being sprayed out. In fact, as long as a solid is produced and it is in the form of a dispersed phase, it can be pumped away; thereafter, concentration can be carried out where necessary, and separation can be done as required! The main thing with this type of system is to pay attention to preventing clogging first; secondly, square shapes should be avoided for reactors. When selecting pumps, considerations must be given to erosion and the presence of solids. Lastly, many errors occur when using ASPEN for calculations! This situation is very common in the phosphorus chemical industry, and the solutions available are quite mature!

The problem I’m facing is that the pipes tend to get clogged. How can this be solved?
