The set of device is a sulphonation production one (vitriolizating) which is based on the multitube film sulphonation reactor. The set of device produces sulfo acid and active substance by making use of all the mostly raw material in detergent industry such as: C12AB, linear alkylbenzene, fatty alcohols, ethoxylated fatty alcohols, alpha-olefins and so on.
There are 2 methods that can be used to control the set. They are apparatus control and computer control.
The following are basic collocation of this set of device:

	-- air drying
	-- sulphur melting and computation
	-- sulphur burning and SO3 producing
	-- sulphonation or vitriolizating
	-- neutralization reaction
	-- exhaust gas disposal

Producing capability: from 500Kg/h to 3,000Kg/h
