Hello, we are drying a powder in a conical dryer under vacuum. The problem we are facing is that the wet powder contains HCl that start to attack the vacuum pump (stainless steel). Is there any way to prevent this? The only thing i can think of is using a little tank we have on site as a...

Hello, We are operating a batch reactor process plant.9 reactors. Each reactor is equiped with a feed vessel. We use vacuum to charge them (feed vessel) At the moment all the feed vessels are on the same vacuum line, connected to a liquid ring vacuum pump. We assume that we charge about 15-20...

redgreen, I don't know why you want to vaporize CO2 for, but you might not need to pay somebody to do something that easy. All you need to do is to create a pressure drop (orifice plate) and you have a nice mixture of gas and dry ice released. The diameter of the orifice will depend on your...

I am in Ireland. At the moment we are operating two liquid ring vacuum pump of 5.5kw each

I totally agree with you all, the dry vacuum pump is the solution. After a rough estimate, I get a pay back time of 3 1/2 year. The only problemn is that the actual economical situation only allows us to make saving but no real investment. Does anyone know second hand dealer with good prices on...

We have 8 reactors on the system, with capacity between 2500L and 5000L. The vacuum required is 30mbar. I was tempting by the solution with the oil, but I am a bit afraid that it might be decompose by some solvent (THF in particular).

it is not trap because at very low pressure (30mmbar), the boiling point of the solvent are very low. We only have cooling capacity to go down to -10degC. As well as this there is some air entry in the system and nitrogen is often blow in the reactor for safety reason which create some kind of a...

Our problem rely on the fact we use lot of different solvents: IPA, MeOH, IMS, Hexane, Toluene, Heptane, Dichloromethane, Xylene, Acetone, Butanol, Ethyl acetate, THF. That's only to name the most commonly used. I read about using oil, but i am afraid of the mixture with water (bad memories of...

We are using liquid ring vacuum pump to create vacuum in few reactor. In order to reduce the water consumption, we recycle the water. The problem we have is that solvent, beiong soluble in water, accumulate in the water. This can build up to 40%. I was wondering if there was any way of replacing...
