One point: as titanium is so called reactive metal it can start to burn temperatures around 500 C. This temperature is greatly depend of size and shape of titanium object.

Some oxidative disinfection chemicals may effect to sealing materials at high temperatures and acidic environments. Practical experience: http://www.birkocorp.com/brewing/yeast.asp http://www.beer-brewing.com/apex/about_this_title/index/beer_brewing_c.htm www.idiclo2.com

I would try some oxidizing solution like hypochlorite or hydrogen peroxide to oxidate chromium to soluble chromium(VI) compounds. Hope this will inspire some new ideas for you.

If dissimilar metals are in electric contact and there is also electrolyte (in this case salt water) there is great possibility for galvanic corrosion. From galvanic series you can see how which of your metal is more nobel than other. Less noble will corrode. Galvanic series is measured in...

One reason for solids build-up is small particle size. Small particles have greater tendency for this kind of buil-up as surface interactions (attractive/repulsive forces) means so much.

At least in small scale molecular sieves (zeolites) are used to separate small amounts of water from alcohols. Regeneration of zeolites is done simply by heating. I think suitable zeolites are for example acidic zeolites. You should also consider centrifugation and membane processes as possible...

I hope here is someone who can advise me. This matter is really not my expertise. We are planning a system where we are going to treat metal plates with molten caustic soda in 500 C temperature for couple of hours. Caustic melts somewhere around 400 C. Every once in a while the caustic should be...

Hello I need some help. I am looking for a sampling equipment for sampling from gas-liquid stream. The relative amounts of gas and liquid in the stream may vary. Do you know any places from where to look for? Or it you know very simple system then i would be very grateful if you could wrote some...

seidelc, Thanks for the relpy. Something about our situation: Every once in a while, 1-2 times/month, there is a process fault in our plant. In this interference there happens a water leak. Water has been collected and used in the process a little by little. In the future we would like to let...

What are the most common hexavalent chromium removal methods and what kind of analysis methods are available for separating hexavalent and total chromium? I would be very grateful of all information, references and www-sites.

You wrote that it is a dosing unit. There is propably not a constant flow in pipes. So you have to also remember out-door pipe-lines. Electric heated lines can be used in this kind of situations. I have seen somekind of electric-heated clothes which can be used for heating in cold climete...

Lignosulfonates are surface active products. There is no exact formula for them. But roughly there is benzene rings in polymeric structure where to is bounded different kind of functional groups (HSO3-, H3CO-, -O-, -OH). There is many kinds of lingnosulfonates which differents from each other by...

Hello, I think that they usually neutralize a dilute sodium silicate solution with dilute acidic solution to form solution which SiO2 amount is app. 1 %. Other activants than acids can also used. I don't know what are these other suitable activants. Acticated silica is usually used as coagulant...

Does anyone have experience of removing silica from water or salt solutions with polyaluminium chloride (PAC) or with other flocculation process like co-precipitation it with magnesium hydroxide? Thank you for your time, Lattar
