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. component Mw Tf (ºC) Tb (ºC) Mol. Vol. δP δH pKa ammonia 17 -77 -33.4 20.8 13 11 4.75 water 18 0 100 18.1 22.8 40.4 15.7

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. Assuming that nucleatio...
