Question 1

A contact sulfuric acid plant produces 98% H2SO4 by absorbing SO3, into 97.3 % H2SO4 solution

Answer 1

95.9 Make up acid = 24.767 tpd
97.3 H2SO4 into the tower = 74.3114 tpd
98 H2SO4 produced = 26. 9168 tpd

Question 2

TiCl4 can be formed by reacting TiO2 with HCl.

Answer 2

TiO2 fed = 0.5394 kg
45% wt HCL fed = 2.05 kg
Ration of recycle to dress TiO2 ore = 0.26

Question 3

Your plant has a furnace that uses a fuel that contains sulfur and negligible amount of nitrogen. + Scrubber reductance

Question 4

A plant produces EtOH as a fuel at 100000 L/day (99.5 % V/V). With fermentation data

Answer 4

Syrup fed per day = 325.3311 tpd
Cane juice fed = 1301.324 tpd
Recovery alcohol = 6.0327%
