MASS TRANSFER

CHEMICAL TECHNOLOGY AND ENGINEERING

21

Mass Transfer

What is the term “the

mass transfer” mean?

What do you remember about mass

transfer?

What is the driving force for mass

transfer?

22

Mass Transfer

Read the text about mass transfer

process and try to explain words in

bold

23

Mass Transfer

diffusivity

based on the concentration gradient

estimation

calculation, evaluating

flux

stream, flow

permit

make possible to smth., allow to smth.

driving forces

make possible to realization of some phenomenon

myriad

huge amount of smth.

conversely

vice versa

stagnant

immovable, static

24

Mass Transfer

transverse velocity

boundary space

transient

temperature remains constant

either

slow movement

isothermal has many aspects

creeping flow

temporary, short term

crosscut rate

multidimensional

both

approach

be right for smth., come near

steady

stable, balanced

interfacial area

conveyance

transposition, movement

25

Mass Transfer

26

Material balance

Draw up the material balance table of the sorption column in which process of separation of threefluoride of bromine and pentafluoride of iodine is produced. Starting composition: IF5 – 0.53 mole fraction; BrF3 – 0.47 mole fraction. Requirements to quality of product: content of BrF3 in IF5 less then 0.05 mole fraction, and contamination of BrF3 by IF5 can be 0.2 mole fraction.

HEAT TRANSFER

CHEMICAL TECHNOLOGY AND ENGINEERING

28

Heat Transfer

Have you ever heard

such term as “the heat transfer”?

What do you remember about heat

transfer?

What is the driving force for heat

transfer?

29

Heat Transfer

Read the text about heat transfer

process and try to explain next terms

Conduction model of heat transfer

Convection model of heat transfer

Radiation model of heat transfer

CHEMICAL REACTORS

CHEMICAL TECHNOLOGY AND ENGINEERING

32

Chemical Reactors

What do you

remember about chemical reactors

classification?

What kind of ideal reactors do you

remember?

What are ideality degrees for ideal

chemical reactors?

33

Chemical Reactors

34

Chemical Reactors

Read the text about chemical

reactors and answer on following

questions again What do you

remember about chemical reactors classification?

What kind of ideal reactors do you remember?

What are ideality degrees for ideal chemical reactors?

35

Chemical Reactors

After text reading fill the table of right sentences numbers

1. The chemical reaction proceeds as the reagents travel through this reactor.

2. The flow rate in must be equal flow rate out, otherwise this reactor will overflow or go empty.

3. It can be economically beneficial to operate several this reactors in series or in parallel.

4. At the inlet to this reactor the rate is very high, but as the concentrations of the reagents decrease and the concentration of the products increases the reaction rate slows.

36

Chemical Reactors

After text reading fill the table of right sentences numbers

5. Infinite number of infinitely small reactors operating in series would be equivalent to a PFR.

6. All calculations performed with this reactor assume perfect mixing.

7. Reagents may be introduced into this reactor at loca-tions in the reactor other than the inlet.
