Example 1.It will cost you $1,500 per ton for anhydrous ammonia. Is that a better deal than 32% UAN at $700 per ton? Yes. If ammonia is $1,500 per ton, the cost per pound of actual N is 91 cents vs. $1.09 per pound for 32% N with prices at $700 per ton. Ammonia may ...
By considering the oxygen utilization efficiency and the cost per pound of oxygen added, optimal design and operating conditions are identified.doi:10.1016/0144-8609(88)90023-4N. NirmalakhandanY.H. LeeR.E. SpeeceElsevier B.V.Aquacultural Engineering...
The Cost of Fertilizer There is a wide range of fertilizer costs. My recent review of this found that a pound of nitrogen can cost anywhere from $33 to over $6,000. Anything over $75/lb is a waste of your money. If you like this post, please share ... FacebookTwitterPinterest...
the net cost per tire runs from an absolute minimum of $1 to as much as $4. That's based on fixed yearly maintenance costs, the condition of the Generator

Nickel is not abundant and the demand for the element has steadily increased. As such, the cost of nickel is projected to escalate, causing the price of nickel-containing austenitic steels to rise and, perhaps, become non-competitive with other materials. Because of the probability of fluctuation...
At a production rate of a pound a day, it is estimated that 95% nitrogen-15 may be produced at a cost of $1,908 per pound ($4.21 per gram) of nitrogen-15. This cost is based upon criteria believed to be optimistic. For example, the cascade design assumes no loss of enriched ...
When one has high-production, irrigated corn on good soils, and he is getting yields up in the 200-bushel range, one can be very efficient with nitrogen, even hitting a ratio of 1 pound of nitrogen per bushel of corn. Many growers, ask if it's worth the cost to make an early ...
We also calculate damage costs per unit of NO2 and NH3 emitted, to quantify some of the environmental impacts of air pollution for use alongside damage costs for human health in policy appraisal. The benefit is 103 pound (33 pound to 237) pound per tonne of NO2 saved, and 414 pound (...
