How are standard gases for synthetic ammonia specified?
Synthetic ammonia standard gas is used for calibrating analytical instruments; the standard gas used varies depending on the type of gas that is analyzed by those instruments. The composition of the standard gas is determined by the manufacturer based on the amount of gas to be analyzed.
I’m sorry; I didn’t ask my question clearly. What I mean is: what is the standard value for ammonia in tons? (For semi-water gas) For example, what does 30,000 m3/nh mean for an electrostatic decoking unit?
Are you referring to the concept of bid price? NM3？
Nm3/h represents the standard volumetric flow rate of gas per hour, with the conditions for Nm3 being 0°C and 1 atm. For gases, their flow rate is generally expressed in terms of volume flow rate. However, since the temperature and pressure of different gases vary, a standard volume is defined so that the volume flow rates of various gases can be standardized.
http://bbs.hcbbs.com/viewthread.php?tid=596207 Take a look at this; it should be helpful to the original poster (regarding the concept of bid prices). Electrostatic defouler 30,000 m3/nh? It should be 30,000 NM3/h; in other words, the processing capacity of electrostatic defouling is 30,000 NM3/h.
The amount of semi-water gas required per ton of ammonia consumed is approximately 3,300–3,400 Nm³, while the amount of shift gas needed is around 4,300 Nm³.
