One method of removing acetone from cellulose acetate is to blow an airstream over the cellulose acetate
Question:
One method of removing acetone from cellulose acetate is to blow an airstream over the cellulose acetate fibers. To know the properties of the air-acclone mixtures. the process control department requires a humidity chart for air-acetone. After investigation, it was found that an absolute humidity range of 0 to 6.0 and a temperature range of 5 to 55°C would be satisfactory, Construct the following portions of such a humidity chart for air-acetone at a total pressure of 760 mm Hg:
(a) Percentage humidity lines for 50 and 100 percent,
(b) Saturated volume versus temperature,
(c) Latent heat of acetone versus temperature,
(d) Humid heat versus humidity,
(e) Adiabatic cooling lines for adiabatic saturation temperatures of 20 and 40°C, and
(f) Wet-bulb temperature (psychrometric) lines for wet-bulb temperatures of 20 and 40°C. The necessary data are given in Table 19.1. For acetone vapor, cp = 1.47 J/g. °C and h/(Mgky) = 1.7 J/g. °C.
