What else can I help you with?
Why cant we use industrial CO2 to mfr urea fertilizer and save the globe from destruction. in fact it was my project in final year engg to design a suitable reactor for making urea.?
Urea is industrially obtained from ammonia and carbon dioxide.
State in which organ urea is added to the blood?
In the Kidneys
Why 12 percent urea used in sailage making even though above 3 percent is toxic to animal?
It's the concentrated amount of urea that will kill, not the diluted amount that is added to silage. Urea will be diluted as it is added to silage, thus making it not toxic and edible for cattle to eat.
Why must air not enter the reactor during cracking?
Air should not enter the reactor during cracking to prevent oxidation of the products. Oxidation can lead to undesired reactions and decrease the efficiency of the cracking process. Additionally, oxygen in the air can cause damage to the catalysts used in the reactor.
What substances should be added to a bio reactor to enable bacteria to grow?
Methionine
What is an air injection reactor?

Why shouldn't air enter an reactor?
Air should not enter a reactor because it can introduce oxygen, which can react with certain chemicals or compounds in the reactor, leading to unwanted reactions or potentially dangerous situations. In some cases, air can also disrupt the controlled environment needed for specific chemical reactions to occur properly.
Why is urea sometimes added to the ingredients in facial moisturizers?
Urea is a great addition to a moisturizer as it is a natural moisturizer and helps keep skin soft and supple. The urea in today's lotions are not derived from urine, although this has been historically the case, but instead from a manufactured chemical known.
Is urea formaldehyde antibacterial?
Urea formaldehyde is not inherently antibacterial. It is a type of thermosetting resin commonly used in adhesives and foams due to its high strength and durability. Antimicrobial properties would need to be added separately if antibacterial effects are desired in a product containing urea formaldehyde.
What is a plug flow reactor and what are its concentration characteristics?
The fluids to be reacted mix and flow through a pipe that is stuffed full of catalyst. The length of the pipe depends on the desired conversion of product (the longer the pipe, the greater the % conversion.) The pipe diameter depends on the desired capacity of the reactor. A recycle stream can be added to mix with the incoming feed if desired. Also one or more of the reactants can be added at different points in the reactor if desirable. If the reaction is exothermic a cooling mechanism will be needed to reduce thermal stress on the reactor walls and/or keep the reactor operating at the desired temperature.
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
Basic operation of plug flow reactor?
The two fluids to be reacted mix and flow through a pipe that is stuffed full of catalyst. The length of the pipe depends on the desired conversion of product. A recycle stream can be added to mix with the incoming feed if desired. Also one or more of the reactants can be added at different points in the reactor if desirable. If the reaction is exothermic a cooling mechanism will be needed to reduce thermal stress on the reactor walls and/or keep the reactor operating at the desired temperature.
