Yes distillation can be used to make that split. It may not be the best option but is an option. Standard design methods will work as long as there is no non ideal interactions.
Yes join an engineering group of some sort. Find an engineer with experience that you can get along with and offer to buy them a beer. Presto instant mentor.
Usually TiCl4 is handled in some type of dry solvent (ie Hexane, toluene, etc) If you are doing an acid flush then water flush why not come in with dry solvent and flush solvent through until dry? Flush solvent through until it is not increasing in moisture content.
Make sure you check the material of construction for ALL wetted parts. Even a small component of the wrong material can result in a failure equivalent to an entirely incorrect pump.
When I have worked at units that campaigned different products it was very dependent on the processes and products being made, for example certain products may have specific times of year they are in demand and that dictates the campaign schedule. You also need to look at things such as turn...
The holes on the exterior pipe in lined pipe is a tell tale hole. That is so when the liner fails you will know immediately avoiding a catastrophic failure of the external pipe. The external pipe is just for support if the process material is compatible with carbon steel pipe you would just...
For reasons already listed, do not double stack gaskets. Do not reuse gasket.
People always look for shortcuts with gaskets and they lead to some of the more severe accidents.
You need to put some thought into what you are doing with this hot tap. Hot tapping is a dangerous operation. Time your tank fill/empty to accommodate the tapping. You could also use a nitrogen purge to give the cooling flow. Maybe fill that section of piping with water to eliminate the...
I have seen butterflies work reasonably well in slurry service with glass reinforced ptfe seats. Regular ptfe seats would fail in short time in the application.
Of course there are valves which would prove more reliable in that service such as ball valves (which at 60" diam would be high...
