Solution to Tutorial 4 Given: F = 1000 kg-mole/hr‚ xF = 0.20 (ethanol is MVC) Feed is saturated liquid‚ thus q = 1.0 xD = 0.80‚ xB = 0.02 (maximum); R = 5/3 First‚ plot the equilibrium curve using the VLE data given. Note that you need to convert mole% ethanol into mole fraction. Then‚ apply the McCabe-Thiele method to find the number of theoretical (equilibrium) trays required for the separation. Step 1: Since R and xD are known (5/3‚ and 0.80 respectively)‚ plot the ROL equation - it

carrying value of an asset is not recoverable. Per the same standards‚ carrying value is not recoverable “if it exceeds the expected future cash flows to be derived from the asset on an undiscounted basis” (FASB‚ ASC 360-10). In the Property Solutions Inc. case‚ the carrying value of the building on 10/1/2017 was $1‚650‚000 and the expected future cash flows are $1‚214‚940. Per the definition of impairment loss stated above‚ the asset is impaired. In calculating the loss‚ we must compare the carrying

The Phyco-Solution Algae are emerging to be one of the most promising long-term‚ sustainable sources of biomass and oils for fuel‚ food‚ feed‚ and other co-products. What makes them so attractive are the large number and wide variety of benefits associated with how and where they grow. Nearly all these benefits stem from the fact that these plants have evolved over billions of years to produce and store energy in the form of oil‚ and they do this more efficiently than any other known natural or

A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine
