Chemical Fill Truck - Standard connection size?
(OP)
Hello,
I'm working on a chemical storage system for a water treatment plant and one of the areas in our scope is providing a fill point in the building for trucks to connect to refill chemical storage tanks. Are there any standards regarding the connection size that would be used here? I'm assuming the connection would be some kind of cam-lock/cam and groove connection.
If it matters, we are dealing with working volumes varying from 5,000 to 15,000 gallons. Chemicals are ferric chloride, sodium hypochlorite and sulfuric acid.
Thanks in advance!

Attached is a document from one sodium hypochlorite supplier that outlines the pipe sizes. .

Providing a flanged valve makes sense as a generic solution - it's hard to predict which company will be providing chemicals at this plant as we are not the end user, but I'll try. Everywhere I'm seeing shows 2" to 3" as a typical solution and I see no harm in going with 3" here. Any typical liquid velocity that pumping would take place at?
Also, are there any other typical provisions for the filling station with non-volatile chemicals like this? I know with some chemicals the truck tank pressure is equalized with inert gas (nitrogen or regular air) as the liquid is pumped into holding tanks. If regular air is used then I would imagine the tanker would have an on-board air supply and no connection to service air would be required from the plant?

Don't believe any air supply is necessary. The tanks should be vented to the atmosphere.
You should also have a safety shower and spill containment to prevent a spill from moving offsite.
