Gas absorption (scrubbing) is an operation in which gas mixture is contacted with a liquid for the purpose of  preferentially  dissolving  one  or  more  components  of  the  gas  mixture  and  to  provide  a solution of them in the liquid phase. (b)What  are  the  differences  between  Physical  Absorption  and  Chemical  Absorption?Demonstrate  their effects on gas absorptionprocess
