Interpretation Introduction

Interpretation:

Calculate the molar flow rate of each element in the coal.

Concept introduction:

It is given that wet coal being used in a power plant at a rate of 8000 lb_m / min has the following composition.

Component Weight % (dry basis)

Ash 7.2

Sulfur 3.5

Hydrogen 5.0

Carbon 75.2

Nitrogen 1.6

Oxygen 7.5

In addition, the wet coal contains 4.58 lb_m H₂ O per lb_m of dry coal.

Units can be converted as,

1 lbm = 0.4536 kg

Molecular weight of each element is as follows,

Sulfur = 32 g/mol

Hydrogen = 1 g/mol

Carbon = 12 g/mol

Nitrogen = 14 g/mol

Oxygen = 16 g/mol

A steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake. The solution that passes through the filter, also 36.4% K,CrO,, is the recycle stream. 1- Draw the flowchart of the system and put all known information. 2- Calculate the rate of evaporation, the rate of production of crystalline K,CrO7, the feed rates that the evaporator and the crystallizer must be designed to handle, and…

Hematite is an iron ore with the following composition: Fe2O3 [MW=159.70]. To make steel, carbon [At. Wt. = 12.01] in the form of coke is used to reduce Fe2O3 to iron metal [At. Wt. = 55.85] as shown below: 3 C + 2 Fe2O3 → 3 CO2 + 4 Fe How many grams of carbon are needed to produce 2,500 grams of iron? Relative to the problem the processing of 798.5 g of hematite ore produced 508.2 g of iron metal. Determine the percent yield of pure iron for this batch?

Q3-A stream of humid air enters a condenser in which 95% of the water vapor in the air is condensed The flow rate of the condensate (the liquid leaving the condenser) is measured and found to be 225 L/h. Dry air may be taken to contain 21 mole% oxygen, with the balance nitrogen. Calculate the flow rate of the gas stream leaving the condenser and the mole fractions of oxygen, nitrogen, and water in this stream.
