Design of differential pressure gauge for reactor bed
Thread Content
I have a design question for the experts: how should the differential pressure gauges for the reactor beds be designed? For example, if a reactor has 4 beds, should differential pressure gauges be installed for each of those 4 beds, in addition to one differential pressure gauge for the entire reactor? Or how should it be designed? I would appreciate advice from those who are experts in this field.
Our unit’s reactor has six beds; it is possible to measure the differential pressure of the first bed, the differential pressure of the first three purification beds, as well as the differential pressure of the entire reactor. Each bed layer on the outer surface of the reactor is equipped with pressure tapping holes, allowing for measurement to be selected according to specific needs.
Actually, your differential pressure design is very good; it allows for the monitoring of the operating condition of each bed layer, and it also enables identification of which bed layer is having problems in abnormal situations.
In fact, in the actual production process, what is of greatest concern is the pressure difference across the upper bed layer. That is, in special situations where there are problems with the lower bed layer, it’s not possible to skip replacing the catalyst in the upper bed layer during maintenance
