Ammonia is a colorless gas with a pungent smell that is produced through the reaction of nitrogen and hydrogen over an iron catalyst. The document outlines the raw materials, reaction, and process for manufacturing ammonia on an industrial scale. Hydrogen and nitrogen are passed over an iron catalyst promoted with oxides of aluminum, zirconium, or silicon at high pressures and 500-550°C to produce ammonia, which is then condensed and collected.
A detailed Powerpoint presentation on the steps in the manufacturing of ammonia from its elements, by the Haber process (including the production of the starting materials and manufacturing conditions and applying the principles of chemical equilibrium and kinetics), the uses of ammonia and the impact of the ammonia industry on the environment.
adipic acid was synthesized from cyclohexanone and concentrated nitric acid. The HNO3 and cyclohexanone were combined very slowly, since the reaction is very exothermic. Once the reaction was complete, the product was allowed to crystallize and the solvent was removed

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Ammonia (NH3) is a compound of nitrogen and hydrogen. It is a
colorless gas with a characteristic pungent smell.
It is one of the most important nitrogenous material. It is a base from
which all the nitrogen containing compounds are derived.
Raw materials
1000kg of NH3 (85% yield)
Hydrogen = 210kg
Nitrogen = 960kg
Catalyst = 0.2kg
Power = 850KWH
Reaction
N2(g) + 3H2(g) 2NH3(g) ΔH = - 22.0kcals
3.
4. Most widely used catalyst for ammonia synthesis is iron with added
promoters e.g. oxides of aluminium, zirconium or silicon at about 3%
concentration and potassium oxide at about 1%. These prevent sintering
and make the catalyst more porous.
The liquid nitrogen wash has the function to remove residual impurities
like CO, Ar and CH4 from a crude hydrogen stream and to establish a
stoichiometric ratio H2/N2 = 3:1.
The manufacture of ammonia is carried out by passing mixture of pure
hydrogen and nitrogen in the proportion of 3:1 by volume under pressure
(100-1000atm depending on conversion required).
Gas flows next through the inside of the tube which contains promoted
iron catalyst at 500-550oC
5. The NH3 is removed by condensation, first with water cooling and
then NH3 refrigeration.
Liquid ammonia is passed into separator section where unreacted
ammonia and hydrogen is separated and liquid ammonia get
collected in storage tank.
Unreacted ammonia and hydrogen get reacted in ammonia converter
which contains promoted iron catalyst at 500-550oC.
Same way after the reaction mixture cooled by water and NH3
refrigeration. Condensate ammonia get separated in separator
section.
