Is there any experience with insulation for the pipes inside the pedestals of various columns in atmospheric and vacuum distillation units, as well as for the bottom sections of these columns?
Thread Content
The unit has been in operation for twelve years; originally, the pipes inside the skirt and the bottom part of the tower were not insulated. With increasing emphasis on energy conservation, we intend to install insulation measures for the pipes leading out of the skirt and for the bottom part of the tower； Moreover, the upper part of the outer surface of the skirt base is also without insulation. However, due to the high temperatures, the fireproof coating cracks, which not only results in a waste of heat but also affects the aesthetic appearance of the device. Do other companies in this industry have any experience with implementing insulation measures? Please share the details of the insulation methods you use, such as adding support rings, insulation rings, insulation nails, etc., as well as what materials are used for insulation
We still have them; we use silicate boards
I would like to ask my colleagues: is insulation applied to the outer and inner walls of the skirt of your units, and what materials are used? Thank you
It is carried out during shutdowns, using aluminum silicate insulation
