Question 2 The operator of a fluidized bed roaster (shown below) routinely measures the chalcocpyrite (CuFeS 2 ) feed rate and moisture content (Stream 1) along with the air flow (Stream 2). As part of an environmental audit, the SO2 and O2 levels in the off-gas are required. a) List all of the mass balance equations, and determine the number of independent mass balance equations. b) Make a table showing, for each stream, the number of independent variables Cn, the number of restrictions Rn, and the number of specified values Vn. Show that the off-gas composition can be calculated given the measured data. Hint: you need to demonstrate closure. c) Using the data in the table below, solve the mass balance for the roaster. Calculate the off-gas volume (in normal cubic meters Nm3/h ) and composition (in volume \%). Perform mass balance either: without tie components or fully using tie components. Note: Stream 2 is enriched air ( 32% oxygen by volume), and Nm3 means "normalized cubic meters" ( 0C and 1atm)
