This is one of our works based on analysing the viability of ammonia recovery and removal from manures extracted from dairy farm. These kinds of approaches could be sustainable solutions for mitigating air pollution as well as could be utilised into sustainable energy productions.
What are some of the alternative measures could be used to recover ammonia from the animal manures those are practiced around world in domestic and industrial phases?
If SSP is added to that it will convert Ammonia sulphate, it is stable compound, the ammonia in that won't volatalize.
Dear Shuraik Kader ,
To prevent air pollution from ammonia emitted from livestock in stables an extraction fan to an acidic water scrubber (pH control) would do very well.
To retain ammonia in the bulk slurry manure, slight acidification (pH control) with any mineral or organic acid will do.
Ammonia (NH₃) is generated because of nitrogen in the feces and urine of pigs and cattle and the uric acid of poultry manure. Ammonia forms from the biological and chemical breakdown of manure protein, uric acid, and urea during manure storage and decomposition. Ammonia Recovery is an award-winning, low-cost, environmentally responsible method of recovering nitrogen, in the form of ammonia, from various dilute waste streams and converting it into concentrated ammonium sulfate. The most effective method for reducing ammonia emissions from manure application sites is to incorporate that manure into soil as quickly as possible. This drastically reduces volatilization losses resulting from exposure to air. Treating common ammonia odors in the home landscape may be done by the addition of carbon or simply applying liberal amounts of water to leach the soil and a lime treatment to increase the soil pH. Excessive ammonia discharged to receiving waters can cause serious ecological problems, such as eutrophication resulting in the depletion of dissolved oxygen, and excessive algal growth. Substantial concentrations of ammonia in wastewater can also cause toxicity to fish and wildlife.

Please can you help me with those questions related to the production of hydrogen from ammonia
Is there any equation as a model which allows you to calculate the potential of hydrogen from ammonia?
Sure, I'd be happy to help you.
According to the basic equation for the Haber-Bosch process that is:
N2 + 3H2 → 2NH3
This equation shows the reaction of nitrogen gas and hydrogen gas to form ammonia. However, in the reverse reaction, ammonia can be dissociated to produce hydrogen gas and nitrogen gas. Therefore, the equation can be written as:
2NH3 → N2 + 3H2
This is the equation for the production of hydrogen from ammonia. By using this equation, you can calculate the potential of hydrogen that can be produced from a certain amount of ammonia. according to this eq. The proportions of NH3 and hydrogen is in the ratio of 2 volume of NH3 to 3 volumes of hydrogen (molar ratio is 2:3). on the other hands, molar mass of NH3 and molar mass of hydrogen is 17 and 2 gr/mol respectively. So you can calculate the potential of hydrogen from NH3.
Thank you. Can we process that equation through software to simulate the potential of hydrogen from ammonia?
Aspen Plus software or even if it's possible to process it on Excel it will also be easier to do the simulation.
Behind a model, there is always a mathematical equation that allows you to calculate what you need.
Hello Sahar Khademi and Kalifa Dembele ,
Thermodynamically, 98-99% conversion of ammonia NH3 to hydrogen H2 is possible at temperatures as low as 425 °C. However this conversion requires a heat input of 30.8 kJ/mole H2 produced and, in practice, the rate of conversion depends on both temperature ande type of catalyst used.
