How to calculate yield and residual carbon indicators?
Thread Content
How is the output of ammonium carbonate generally converted into the output of synthetic ammonia? I heard there are several options: 4.2:1, 4.4:1, and 4.75:1. Which one is more reasonable, please? I'm a beginner. . . I would like to ask specifically: please don’t ask what the typical residual carbon content is This post was last edited by zhouyvwei on 2009-3-29 17:18]
2.1 Ammonia consumption per unit of ammonium bicarbonate: The ammonia consumed in the production of ammonium bicarbonate is calculated based on the amount of synthetic ammonia used to produce that quantity of ammonium bicarbonate. 2.1.1 Calculation formula: Ammonia consumption per unit of ammonium bicarbonate (kg/ton) = (Actual production volume of ammonium bicarbonate in tons) × (Total actual ammonia consumption in tons) × 1000. 2.1.2 Sub-item: The total ammonia consumption is determined based on the flow rate of liquid ammonia; alternatively, it can also be calculated by considering the actual nitrogen content of the final ammonium bicarbonate product and using a utilization rate of 96%. Actual total ammonia consumption = ×1.26654. Where: 1.26654 = 1÷(0.82245×96%), with 0.82245 representing the theoretical nitrogen content in ammonia, and 96% representing the utilization rate of ammonia in solid fertilizers and ammonia solutions. 2.1.3 Numerator: The scope of statistics on the actual production volume of ammonium bicarbonate is specified in 1.1.1 of this chapter.
Excuse me, upstairs. Is this the same way calculation is done when counting production volume in the actual manufacturing process? It’s so complicated.
Depressed. We use a conversion ratio of 4.4:1, which invisibly increases coal consumption.
Perhaps the percentage content is different!
The residue carbon content should generally be kept below 15%
