(a) Interpretation: Draw a flowchart for the catalytic dehydrogenation of propane from the description of this process that begins section 4.3a. Label all feed, product, and connecting streams between units. Concept introduction: When a few process information is given and the calculation is to be done on the basis of the information, then in such conditions, flowchart creation is the best way to deal with. It is formed with the help of boxes and arrows to show the process and outline the process units. The arrow lines can show inputs and outputs which help in better understanding of the process.

Question

(a) Powder metallurgy (PM) is a net-shape forming process by which fine powdered materials are blended, pressed into the desired shape (compacted), and then heated (sintered) in a controlled atmosphere to bond the contacting surfaces of the particles and establish desired properties. i) Justify the reasons why powder-metal parts are commonly used for machine elements which requiring good tribological characteristics. ii) Compaction is the step in which high pressure is applied to the powders to form them into the desired shapes. The purposes of compaction are to obtain the required shape, density, and particle-to-particle contact. In your opinion, is there any density variation in the compacting of powders? Justify your answer. If your answer is yes, propose appropriate methods to reduce the variation.

Answer 1

Question

Chapter 4, Problem 4.7P

Interpretation Introduction

(a)

Interpretation:

Draw a flowchart for the catalytic dehydrogenation of propane from the description of this process that begins section 4.3a. Label all feed, product, and connecting streams between units.

Concept introduction:

When a few process information is given and the calculation is to be done on the basis of the information, then in such conditions, flowchart creation is the best way to deal with. It is formed with the help of boxes and arrows to show the process and outline the process units. The arrow lines can show inputs and outputs which help in better understanding of the process.

Interpretation Introduction

(b)

Interpretation:

Write clear statements of the overall objective of the process and the functions of each of the process units (the preheater, the reactor, the absorption and stripping towers and the distillation column).

b) A plot of land was explored and found to contain 1,000,000 grams of gold. The average goldconcentration was found to be 0.8 grams per ton. A mine was set up on it and sluice boxes were used as the main gold recovery units and recovered200,000 g of gold from 80% of the ore. The concentration ratio of the sluice boxes was 10,000.The field was mined again. On this occasion bowl concentrators were used. The feed used wasestimated to be 800,000 tons and the concentration ratio of this unit was 20,000. 750,000 grams ofgold was recovered. Calculate the following: i) the Quantity and grade concentrate from the sluice boxes .................. ..................... ii) the quantity and grade of the concentrate from the bowl concentrator plant. .............. iii) the quantity and grade of the material remaining at this location...................................
