Assumptions
1. The dispersion is basic, so C8 is assumed to be in salt form. The vapor pressure of the salt at 100C is -0.07 mm Hg, so virtually
during drying. C8 present in the dispersion applied to packing yarns is assumed to remain with the
yarn,______________
5% makes it to the hot rolls, where it evaporates and goes to the sintering exhaust scrubber. 3. The boiling point of C8 in both acid and salt forms is ~375F. Since the yarn reaches ~620F during sintering, the 5% of C8 that re assumed to boil off in sintering and goes to the
4. Exhaust scrubbing is assumed to be 80%. Csoncsreuqubenbtley,rI.a_s_su_m_e_8_0%__of_th_e_5_%_o_f C_8_th_a_t e_n_te_rs_th_e_s_in_ter_in_g_ex_h_au_s_t i_s _re_m_o
