Hi there
Any body knows what this product is? I need the chemical formula and the use of this product.
Thanks for your help

it may give you an idea of its chemical structure.
RE: Lignosulfonate
I'd wait for confirmation before taking this as gospels since this is a left over bit of information from some years ago.

the dust. I think -- I am not sure -- they used it as
binder for coal-briquettes.

They are used mainly as binders and dispersing agents. Most important use is in oil industries where they use it as dispersing agent in oil drilling. It is also used as plasticer and water reducing agent in makeing congrete. There is quit many uses for it.

RE: Lignosulfonate
In our process we fluidize iron ore with a CO/H2 reach gas as reducing agent. This is to produce directly reduced iron (DRI) 92% metalised for steel production. The gas also contains CO2, CH4 and N2.
Lignosulfonate as recently been adopted as a mean of dust control at the iron ore stockyard.
Coincidentally exactly at the time this product was adopted we are now having clustering of our product. Clustering is making our operation very difficult.
Can this product cause this clustering effect?
Just for interest: the shaft is at about 800 deg. C
Localized overheating can cause clustering. Clustering can also be caused by some form of oxidation however the atmosphere is highly reducing in the shaft.

There is no single molecular formula for lignosulfonates. Any good kraft pulping text, or possibly TAPPI in the US, CPPA, SAPPI, etc. elsewhere, should be a source of specific information on the chemistry and structures.
