Expansion Characteristics of Polymeric Resins
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Expansion characteristics of polymeric resins have been investigated in a solid-liquid fluidized bed of 100 mm i.d. and 1.2 m in height using water as a fluidizing medium. The effect of solid particle size and density on expansion characteristics has been studied with an emphasis on the swelling characteristics, in particular. The experimental velocity- voidage data have been modeled using Richardson-Zaki equation. It has been observed that the swelling of the resin tend to increase terminal settling velocity of the resin due to an increase in the diameter. The swelling ratio for strong base anion exchange resin (A-36) and strong acid cation exchange resin (T-42) was found to be 1.19 and 1.34, respectively. Moreover, it has also been observed that RZ represents the experimental velocity- voidage data very well with standard deviation of 0.05%.
