1) Introduction
2) What is cryogenics?
3) Working of cryogenic technology
4) Applications
5) Advantages
6) Disadvantages
7) Conclusion
3. 1) It is a Branch Of Engineering Which
Deals With Very Low Temprature
2) Here Temprature Can Be Low As
120k or -153°C or 243.4°F
3) Properties Of Elements Change
When The Temprature Goes That Low
1) Introduction
4. What is
cryogenics?
• The word cryogenics stems from Greek
word cryos and means "the production of
freezing cold“, the term is used today as a
synonym for the low-temperature state.
• Dry ice also have very low Temprature
but technically it is not considered as
cryogenics
5. How and when?
1) The development of cryogenics as a low temperature science is
a direct result of attempts by nineteenth century scientists to
liquefy the permanent gases.
2) Michael Faraday, had succeeded, by 1845, in liquefying
most of the gases then known to exist.
3) His procedure consisted of cooling the gas by immersion in
a bath of ether and dry ice and then pressurizing the gas until it
liquefied.

1791-1867
7. CRYOCOOLERS
Normal phase change does not
go below -50°C Cryocoolers are
used in Cryogenic Technology to
lower down the temprature of
gases upto -153°C .
WORKING
gases on room temprature,compressed
heavily with cryocoolers gains temprature
To regulate that gain coolent is passed to
dissipate the heat and commpressed gas
becomes cool after that the pressure is
released and due to this gas loses more
heat and becomes supercooled liquid
9. Insulator used
Most of the Insulators cannot
Stop the heat gain From outside,
so for that reason Vaccum Flask
is used which is made of custom
alloy
10. Applications
1) Medical uses For Oxygen
2) Magnetic resonance imaging
3) Cryogenic Engine
There are plenty of applications of
cryogenic technology we will take a
look on few of them
11. When we transfer Oxygen in gaeous
form it takes so much space and does not
expand as much but in cryocooling the oxygen’s
phase changes to liquid from gaseous form and
it becomes easy to transport oxygen
for comparison 1 litre liquid oxygen can
expand upto 861 litre gaseous form of oxygen

medical use

12. MRI scanning
Liquid Helium is Used in MRI machine To cool
down the superconducting magnets
The supeconductiong magnets generates
Images of Human body and It operates at a
temprature of -269°C
opportunities in MRI
MRI scanning uses
liquid helium to
cool down
supeconducting
magnets since long
time but nowadays
more affordable
options are
availible to create
similar temprature
but no one
patented any
alternative
14. USE IN CRYOGENIC ENGINE
The cryogenic Engine Uses 2 liquified Gases 1 for fuel
and other one as an oxidiser
H2
(FUEL)
O2
(OXIDISER)
15. USE IN CRYOGENIC ENGINE
The main components of a Cryogine engine are A
combustion/thrust chamber, igniter, fuel injector, fuel
cryo pumps, oxidizer cryo pumps, gas turbine, cryo
valves, regulators, fuel tanks, and a rocket engine
nozzle. Liquid oxygen (LOX) and liquid hydrogen (LH2),
which liquefy at -183 degrees Celsius and -253 degrees
Celsius, respectively, are used as propellants in
cryogenic engines. LH2 and LOX are kept in the
appropriate tanks. Individual booster pumps are then
used to pump them into the turbopump from there,
ensuring a high flow rate of propellants inside the
combustion/thrust chamber.
17. 1) Has higher ,ass flow rate than fossil fuels
2) Rapid Freezing
3) Inhibition of bacterial growth
4) Save significant amount of space
5) Limited dehydration
ADVANTAGES
18. 1) LNG a Cryogenic fuel might cause very large explosion if
fuel spill during ignition
2) Stoarage tanks must be able to withstand high pressure
3) The density is more extensive than gaseous form
4) Human contact is fatal as water becomes ice
instantly with contact
DISADVANTAGES
19. conclusion
In conclusion, cryogenic cooling can not only offer
advantages in terms of wear and tear, productivity
and finish (roughness), but is also a neutral and
environmentally-friendly method that translates into
other advantages.
