How to determine the thickness of the insulation layer for a distillation tower
Thread Content
How is the thickness of the insulation layer for a distillation tower calculated? What is considered a normal level of heat loss after insulation is applied?
You can refer to the general principles for adiabatic design or the design guidelines; these are generally based on temperature and the outer diameter of the cylinder
Design Code for Thermal Insulation of Industrial Equipment and Piping
Set an outer temperature by yourself and then do the calculation. Generally, it should not feel hot to the touch; it can be at a warm temperature of 30-35 degrees? To reach room temperature, it needs to be very thick.
