Effluent Analysis

[Usman]

Kindly tell me the name of the instruments used for the detection or analysis of Ammonia in the effluent?

[Qaiser]

Ammonia in effluent is analysed normally in lab. Usually companies take two spot samples a day & one 24-hrs composite sample. This sampling schedule is in agreement with EPA in Pakitan.
Also, online NH3 analyzers for effluent are available in the market.
We had searched once a vendor in Karachi, Pakistan for this pupose. Find his contact below. Hope it'd be helpful.

Queries are welcome, if any.

usman, there are certain companies providing such online analyzers (hope you require analyzer rather a detector). Most commonly I have heard about is AM200. It has some delay, as usually in analyzers are. Anyhow you can get more info at http://www.p-a-i.de/e/am200.htm

Thank

[Usman]

kindly brother guide me
what is the method to convert ppm calculations into percentage and percentage calculations into ppm.

[arcpro]

10,000 ppm = 10000 / 1,00,0000 = 1 percent
1 ppm = 1 / 1000000 = 0.00001 percent

plz guide me about the control measures of Ammonia emissions in Nitrogen-fertilizer industry.
(Control measures including engineering control, administrative control or work practice control.)

Dear Usman,
I'd suggest you to go thru the attached booklets. It'd help you clarify a lot of questions in your mind.
These booklets were prepared by member companies of the European Fertilizer Manufacturers’ Association (EFMA) on Best Available Techniques (BAT) in response of European Union directive on Integrated Pollution Prevention and Control (a.k.a. EU IPPC Directive).
EFMA carries out a survey on emissions & effluents every two years based on the emissions levels defined in BAT booklets & issues a detailed report (graphical representation is great!). Fertilizer companies volanteerily participate in the survey worldwide, including Pakistan.
I've attached only two relevant to NH3 & Urea being the most common processes here in our part of globe.
I may send any of listed below, if req. Pl note that it is available for free.

1. Production of Ammonia
2. Production of Nitric Acid
3. Production of Sulphuric Acid
4. Production of Phosphoric Acid
5. Production of Urea and Urea-Ammonium Nitrate
6. Production of Ammonium Nitrate and Calcium Ammonium Nitrate
7. Production of NPK Compound Fertilizers by Nitrophosphate Route
8. Production of NPK Compound Fertilizers by Mixed Acid Route

You are requested to feel free to discuss further.
