A mixture containing 7,000 kmol/hr of water and 3,000 ppm by weight of ammonia at 77 ºC and 1 atm is to be 
processed to remove 90% of ammonia. Some of properties of ammonia and water are listed below.

Assuming that nucleation is fast and flocculation is negligible, and that the solution has properties close to those of 
water, estimate the following: 
a) the time over which diffusion will limit growth (i.e. time for homogeneity)

o precipitate catalase from an enzyme mixture which includes cholesterol oxidase, our desired product. 
Catalase has a molecular weight of 250,000, a precipitate density of 1.3 g/cm3 
, an average diameter in solution of 10 
nm, and an average diffusion coefficient of 4.1 x 10-7 
cm2 
/sec. It is to be precipitated by a sudden pH change in a 
100 liter tank stirred with a 0.1 hp motor. The feed concentration is 0.2 g/liter and sticking coefficient is about 0.05 
sec.
