Concept explainers
(a)
Interpretation:
The volumetric flow rate is to be estimated that the compressor must be capable of delivering if no gases are recycled. The required volume of the catalyst bed is to be estimated.
Concept introduction:
The Kay’s rule is related to the use of pseudo critical properties such as temperature, pressure and volume for the calculation of pseudo reduced properties that can be used in compressibility charts.
(b)
Interpretation:
The volumetric flow rate that the compressor must be capable of delivering assuming that the methanol produced is completely recovered in the condenser is to be estimated. The required volume of the catalyst bed is to be estimated.

- 4. A feed stream containing C8 and C10 hydrocarbons is split into 3 product streams: an overhead fraction, a middle cut and a bottom fraction, whose mole fraction compositions are shown below. Seventy percent of the C8 entering the column in the feed is recovered in the overhead. On the basis of 100 lb-moles/h of feed, determine the molar flow rates of the 3 product streams.

A customer has ordered the airplane but requested that its total weight be reduced by 10 percent for fuel saving purposes. An engineer in the design and analysis department has suggested that the weight saving objective can be accomplished by replacing the current aluminum alloy of the floor beams with another one containing 3 wt% Li and 1 wt% Cu. Is this possible? Answer the question by first determining the weight saving that will take place using the Al-Li alloy. Assume weighted averages of density and use the following densities for the mentioned materials: Al = 2.70 g/cm³ Cu = 8.92 g/cm³ Mg = 1.74 g/cm³ Li = 0.53 g/cm³arrow_forwardesc pock Ethanol (C₂H6O) burns in air C₂H60) +O2(g) → CO2(g) + H₂O (1) Balance the equation and determine the volume of air in liters at 35°C and 790 mm Hg required to burn 227 g of ethanol.

Develop the combustion equation and determine (a) the percentage of the excess air (b) the air fuel ratio. (Solve for 100 kmol of dry products).arrow_forward2. In an ethanol production plant, a separator produces a 99% ethanol product from a feedstock stream containing 85% water and 15% ethanol at a rate of 450 Ib/min. The separator has two outlet streams: the ethanol product outlet stream (99% ethanol) and a residual water stream. 30% of the feedstock is bypassed and mixed with the residual water stream leaving the separator. If 60% of the ethanol entering the separator is recovered in the product stream, determine the composition of the residual water stream just after leaving the separator and the composition of the residual stream after mixing with the bypass stream.arrow_forward3.
