> Jacketed Glass Reactor, Capacity: <1 KL
What is the meaning of KL? Kiloliter?
Thousands of liters?

> Stage II is performed in SS Reactor OB/RE22
There is a provision of Intermediate drier OB/VD-04 with 12 trays capacity of 25 to 30 Kg
Centrifugation is performed in OB/CF-05 under Nitrogen blanket.
What is intermediate dryer? What does it do in pharmeceutical production?

@Zenix You're welcome to try, but you'd definitely get it wrong
I've mentioned my name somewhere on SE chat before, and often too
@CowperKettle this I think:
Vacuum drying
Vacuum drying is the mass transfer operation in which the moisture present in a substance, usually a wet solid, is removed by means of creating a vacuum. In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential unit operation to remove moisture. Vacuum drying is generally used for the drying of substances which are hygroscopic and heat sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapor pressure of the water, causing it to boil. With the help of vacuum pumps, the pressure is...
@user1271772 Jonsca is a mod on Web Apps and Chemistry. He specifically mentioned suspending his activity on those. He's also disgusted by SE's blanket PR responses, so he wouldn't want to visit and contribute to others either
Well, SE is trying to fix things, and I don't think firing a popular mod (even if they haven't active for such a long time) is going to help. They're focused on other things, and let's see if they regain our trust
If the flag queue is starting to become cumbersome, there's always mod elections. That's up to the mods to say and arrange
It's not just a matter of the number of mods. If it was, SO would have had two hundred mods by now

Q: Effect of concentration on rate

Michael Faraday How do I solve this question? My thinking is this: since O2 is not a reactant in any step, and since the reaction rate depends only on the reactants, increasing the concentration of O2 does not affect the rate of the reaction. Is my thinking correct?

Hey a a random question is the distance of a particular value of n in one element the same as the distance from a particular value of n in another element?
Is this the concept that is used in spectroscopy or is it instead the idea that they have different arrangements of electrons into an orbital, so by exciting them to different levels you can release specific frequencies of light which then result in a spectrum?
