Vacuum is probably the most critical aspect of the process, yet normally most people go by the general thumb rule that the bigger the vessel / equipment volume, bigger the vacuum pump required.
Thus, most people end up purchasing much a bigger size of pump (to be on the safe side ) than actually required (much to the manufactures delight ) . As the onus of selection is on the purchaser / client .
The scientific way is to understand the function of the pump w. r. t. the process. The function of a vacuum pump in chemical process is :
• It evacuates the equipment : For this one needs to know the volume of vessel & the charge of material. • It handles any air leakages in the equipment : For this one needs to know the Vacuum drop in mm Hg/hr. • It handles non condensables : For this one needs to know the rate of non condensables to be handled by the pump in kg/hr.
If the above data is accurately given, then sizing of the vacuum pump can be done perfectly thus ensuring that the process time & temperature is down to a minimum and the vacuum and product quality is optimum.
We, at PATKAR VACUULAB take the onus of pump selection / sizing on ourselves thus reducing the chances of oversizing or under sizing the pump w.r.t. your process.
