What is everyone’s ammonia consumption per ton of alkali?
Thread Content
Currently, the soda ash market is in a downturn; although prices have seen some increase, the situation remains severe. For this reason, cost control is particularly important! Through continuous efforts over a period of time, our company has now achieved a target value of 360 kg of ammonia per ton of alkali; the actual value is 355 kg of ammonia per ton of alkali. The leader believes there is still room for improvement; it is necessary to continue looking for weaknesses and identifying the reasons. (Note: Our company uses the caustic soda synthesis process based on concentrated gas.) I would like to ask for advice from everyone on this forum: what is your ammonia consumption? What are your main means of control?

Now that Yihua has taken over the TWO loop, the ammonia consumption is not that high. Just over 330. One indicator is measured in money, and the oversight is quite strict
As you said, it’s not easy to work there; they keep deducting money from your salary
When absorbing ammonia, it is necessary to control the α and β values properly. Attention should be paid to the recovery of carbonization exhaust gases and calcination exhaust gases in order to reduce leaks from the solution. Additionally, it is important to increase production levels, as lower production inevitably leads to higher consumption.
We keep the B value around 1.00. Could we discuss your specific control methods upstairs?
Around 340 kg, with the β value kept at around 1.00; exceeding this limit is strictly prohibited, and violators will be punished. Control measures are to recover carbonized exhaust gases and filter the exhaust gases. The increase in the overall volume of control systems helps to prevent leaks.
Regarding ammonia consumption, at the previous Soda Ash Technology Annual Conference in 2009, the president mentioned that Huainan Debang had reached an advanced level in the industry. They also use the double-alkali process; the original poster can take a look at the achievements they have made in reducing ammonia consumption. Of course, we’re also learning * right now, hehe… Let’s cheer each other on!
About 350 kg. It’s a bit larger than the theoretical value.
What all the above-mentioned people have said relates to the combined alkali process; the ammonia consumption in the ammonia-alkali industry is significantly higher than that in the combined alkali process, generally exceeding 3.6 kilograms per ton. Most are between 3.8 and 4.5. Measures: 1. Strengthen the control of various process parameters ； 2. Eliminate any leaks or losses from the equipment ； 3. Ensure high and stable yields in production. 1# Mortal World
Ammonia consumption is around 330 kg per ton of alkali. Control measures: 1. Strict process parameters ； 2. Ensure proper alkalinity and reduce the washing equivalence ； 3. Control the temperature of the crystallizer properly to ensure good quality of NH4Cl crystals; this not only helps reduce the amount of water used in the separator but also prevents tiny NH4Cl particles from being carried along in M2, thereby avoiding an excess level of CNH4 in carbonization tower AII. Wait, there are many methods, but they are interrelated; think carefully about them during production.
