This assignment asks you to write a 300 piece on various responses to the apology Pope Francis gave on July 25, 2022 at Maskwakis. Think of your writing here as a description of a conversation, with different people offering distinctive responses, each speaking from their particular individual and community contexts. As you describe the 'conversation,' you should name the speakers but also use a phrase to describe who the speaker is.  Do not be random about how you describe the speaker, but try to highlight aspects of their identity that are highly relevant to their participation in this conversation.

A multiple-effect evaporator is an apparatus for efficiently by means of the heat from steam to evaporate water. Water is boiled in a sequence of vessels, each held at a tower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapour boiled off in one vessel can be used to heat the next. and only the first vessel requires an external source of heat. While in theory evaporators may be built with an arbitrarily large number of stages, evaporators with more than four stages are rarely practical except in systems where the liquor is the desired product such as in chemical recovery systems where up to seven effects are used. Multiple effect evaporation commonly uses sensible heat in the condensate to preheat liquor to be flashed. In practice the design liquid flow paths can be somewhat complicated in order to extract the most recoverable heat and to obtain the highest evaporation rates from the equipment. The evaporator is used to remove the solvent from the sotution. In the four stage evaporation system used in sugar cane industries, a 50% by mass sugar solution is concentrated to by 65% by evaporating an equal amount of water in each of four stages. With total input of 50,057 lb/h, a product stream of 35,057lb/h is produced.

The reverse water-gas reaction is an undesirable side-reaction during industrial hydrogen production:

Producer gas is fuel gas that is manufactured by blowing a coke or coal with air and steam simultaneously. It mainly consists of carbon monoxide, hydrogen, as well as substantial amounts of nitrogen. The caloric value of the producer gas is low. Such a producer gas contains 28% CO, 3.5% CO2, 0.5% 02 and 68% N2. 100 kg of this gas is burned with 20% excess air. If the combustion is only 90% complete, determine the following:

(a) The composition of the flue gas

(b) The weight of the gaseous products

(c) If the excess air increased to 40%, whether the combustion reaction in completed? Justify your anaswer.

Butane is burned with air. No carbon monoxide is present in the combustion produets.
Calculate the molar composition of the product gas for each of the following three cases: (i)
theoretical air supplicd, 100 % conversion of butane: (i) 20% excess air. 100% conversion of
butane: and (il) 33% excess air. 90% conversion of butane.

Flue gas is the gas leaving to the atmosphere via a duct, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen derived from the combustion of air, carbon dioxide (CO2). and water vapor as well as excess oxygen. It further contains a small percentage of a number of pollutants, such as particulate matter, carbon monoxide, nitrogen oxides, and sulfur oxides. As per the annual report released by sohar power plant, the company produces the flue gas in to atmosphere and it has the following composition by volume percent:

 CO: 34.8, H2: 42.0, CH4: 0.4, CO2: 5.5, O2: 0.2, and N2: 17.1. Calculate

(a) The composition in mass percent

(b) The average molecular weight

(c) The density at standard conditions in kg/m.

Assume suitable conditions/ assumptions to solve the problem and justify your assumptions. Write the step by step by procedure of solution.

The air separation unit is an important energy-consuming unit in the process of ammonia synthesis. For the ammonia process with pure oxygen gasification, the purity of oxygen products in the air separation unit is generally 99.6%. If the oxygen purity from the air separation is reduced properly, its energy consumption will decrease effectively, and the energy consumption of the whole ammonia process may further decrease, as the nitrogen element is needed for ammonia synthesis. However, with the increase of the flow rate, the operating cost of the subsequent unit would increase, so there is an optimal purity that could minimize the energy consumption of the whole process. An ammonia-air mixture containing 10% ammonia is sent to an absorber in which 90% of ammonia is absorbed.

(a) What is the mole fraction of ammonia in the gas leaving?

(b) Express the composition of the exit gas from the absorber in weight percent.

(c) What is the average molecular weight of the gas entering and leaving the column? (Average molecular weight of air is 29)

Gas-liquid absorption columns are primarily used to clean gas streams from chemicals that should not be released into the environment. Sulfur dioxide (SO2), carbon dioxide (CO2) and other gases are found in industrial waste streams and contribute to air pollution. A gas stream flowing at 100 mol/h contains 20 mol% oxygen, 70 mol% N2, and 10 mol% H20 is passed through a packed column with absorbent solids. The absorbents in the column absorb 97% of the water but none of the gases. Calculate the mole fraction of oxygen in the product gas.

A client who is experiencing facial pain comes to the primary health care clinic where you are completing a student rotation. She tells you her pain is unrelenting and unbearable. Following health history and physical assessment the primary care NP made a tentative diagnosis of trigeminal neuralgia and referred her to neurology and started her on carbamazepine, an anti convulsant drug. The neurology/neurosurgery team confirmed the diagnosis of trigeminal neuralgia and, after an unsuccessful trial of medication, the client decided to proceed to microvascular decompression (MVD). From what you have learned so far, describe your post-operative assessment either immediately after surgery, after 24 hours, or on discharge from hospital.

Imagine that a patient arrives at the medical office you work at and is sick, vomiting, in pain, or even injured and bleeding. This is the first time the patient has been seen by your office. The office is filled with patients who need to be seen and the phone is ringing as other patients call to schedule appointments. The patient walks up the counter and... Given this scenario, explain how you, as a Medical Office Assistant, would respond.

7. The most efficient way to separate the hydrocarbons into smaller fractions is called fractional distillation. Short hydrocarbons (one to five carbons) are gases at room temperatures because they have such low boiling points. A hydrocarbon feed CH consisting of a mixture of propane (20%), isobutene (30%), isopentane (20%), and n pentane (30%) is fractionated at a rate of 100 kg/h into a distillate that contains all the propane and 78% of the isopentane in the feed. The mole fraction of isobutane in the distillate is 0.378. The bottom stream contains all the n-pentane fed to the unit. Determine the flow rate of the bottom stream. Write inlet and outlet stream with different system of units.

At 300 K, the composition of the upper and lower layers are 70% and 9% by weight of phenol respectively. If 40 g of phenol and 60 g of water are mixed and the layers are allowed to separate at 300 K, what will be the weights of the two layers?
