A case study on Process Condensate Stripper in Ammonia Plant by Prem Baboo.pdfPremBaboo4
A trouble shooting case study in Fertilizers unit, India.Solving the problem of Feed/Effluent Exchanger E-3321A/B in Process Condensate stripping section of Ammonia plant by Analytical approach. The problem solved by in house experts without changing the heat exchangers while others plant change the heat exchangers. Number of modification done and huge amount of energy saved. The paper intended how to save energy by changing heat exchanger and pressure of PC Stripper. The treated process condensate was earlier cooled by CW in final cooler from about 90ºC to 40ºC. This available heat of PC is being recovered by exchanging heat with DM water in a plate heat exchanger. The pressure of PC stripper has been raised to about 1.5 kg/cm²g to make the extra heat recovery possible. Now pressure is 41.5 kg/cm2. A new Plate heat exchanger was procured & installed for the heat recovery.
Some fact about Ammonia Production by Prem Baboo.pdfPremBaboo4
Operation of the plant is mainly supervised by the operators in the control room, who monitor the various instruments and adjust operating conditions in order to obtain satisfactory operation. They should also react when an alarm is activated. In some cases they can re-establish normal conditions by adjusting the controls in the control room; in other cases they give instructions to a field operator to make the necessary adjustments at various locations in the plant. Field operators work in regular shifts in the plant, especially in the reforming section, in order to supervise the firing of the reformer and the temperature of the tubes in the reformer, to record local instrument readings, and to notice any irregularities such as leaks. Every change of temperature of the reformer a little change can bring big change resulting energy losses, e.g. temperature of the primary reformer and CO slip losses in methanation etc.

3. Any mixture of solid
liquid or a gas gas is called
slurry.
Sloppy mud, cement or
mixture of additives in
petrochemicals.
4. Slurry reactors are three-phase
reactors, meaning they can be
used to react solids, liquids,
and gases simultaneously.
They usually consist of a solids
suspended in a liquid, through
which a gas is bubbled. They
can operate in either semi-
batch or continuous mode.
5. Types Of Slurry Reactors are :
Bubble Column Reactor
Fischer Tropsch Reactor
Slurry Batch Reactor

9. Reaction tank
Made of glass or
steel.
Hold Media and
catalyst.
Additional parts
are mounted on it.
10. Sparger
Used to introduce air in
reactor.
Install at the bottom, consist
of tube and holes for escape
air and gases.
11. Cooling Coils
Water is circulated
through these coils to
lower the temperature
inside the reaction
vessel.
13. Hydro-cloning Section
Hydro-cloning section is
attached separate to the
vessel.
A Hydro-clone is a static
device that applies
centrifugal force to a liquid
mixture so as to promote
the separation of heavy
and light components.
14. Carbon monoxide and hydrogen react over a
catalyst to produce methanol.
Catalyst is a mixture of copper, zinc oxide, and
alumina.
At 5–10 MPa (50–100 atm) and 250 °C.
CO + 2 H2 → CH3OH
20. problem cause consequence solution

feed gas.
Very high superficial
velocity of the gas
feed.

sparger
21. problem cause consequence solution
Coagulant formation
of solid catalyst in the
liquid oil.
Very high
temperature.
Agitation will not be
done properly.
Regenerate the
catalyst.
Orifice of the sparger
damage.
Over time Fine particles of
catalyst will enter in
the sparger and chock
the sparger.
Change the orifice and
clean the sparger.
22. High heat capacity to provide good temperature
control.
Potentially high reaction rate per unit volume of
reactor if the catalyst is highly active.
Easy heat recovery.
Adaptability to either batch or flow processing.
The catalyst may readily be removed and replaced
if its working life is relatively short.
Because of high intraparticle diffusion rate, small
particles can be used.
23. Generation of fine particles by abrasion of the
catalyst.
Catalyst removal by filtration may provoke problems
with possible plugging difficulties on filters, further
time of operation, and the costs of filtering systems
may be a substantial portion of the capital
investment.
Higher catalyst consumption than that of fixed - bed
reactors.
Back mixed flow and the volume of the reactor are
not fully utilized.
24. Stack gas scrubbing with lime or magnesia.
Waste water treatment.
Ethylene oxychlorination.
Oxidation of toluene to benzoic acid.
Ethylene oxidation to acetaldehyde.
Olefin polymerization using catalyst suspension.
Fatty oil hydrogenation with catalytic
suspension.
25. On January 11, 2006, an
explosion and fire
occurred at the City of
Daytona Beach, Bethune
Point WWTP in Daytona
Beach, Florida. Two
employees died and one
was severely burned
after.
26. a worker using a cutting torch accidentally
ignited vapors coming from the methanol
storage tank vent.
An explosion inside the tank followed,
causing the attached piping to fail and
release about 3,000 gallons of methanol,
which burned.
