Overview of the manufacturing process

Organic sulfates and sulfonates are industrially manufactured by reacting organic compounds (alkybenzenes, fatty alcohols, ethoxilated fatty alcohols, methyl esters, alfa-olefines, etc.) with diluted gaseous SO3.

The reaction is called sulfation or sulfonation. 
The sulfonic acids obtained by processing some alkylates (most notably: LABSA) can be marketed as such, as they can find direct industrial application.

Otherwise, the organic acids coming either from sulfation or sulfonation reaction are neutralized to form the relevant organic salts (most notably: SLES, SLS, LABS and AOS).

A finishing phase is required in order to remove possible impurities produced by secondary reactions (e.g.: dioxane and sultones), as well as to stabilize, homogenize and dilute the products.


The products of BALCHEM sulphonation plants find prominent application as cleaning and foaming agents in detergents.

Our Products


PROCESS AIR DRYING

This unit is  a fundamental step in the production of process air for the plant.


SULPHUR BURNER
AND COMBUSTION FURNACE

This unit has the scope to produce SO2 by combining in stoichiometric ratio, the dry air and the sulphur which is sprayed through a special nozzle.


SO2-SO3 CONVERSION

The SO2 stream enters  the conversion tower equipped with 3 or 4 catalyst layers (depending  on plant capacity) with the purpose to convert SO2 in SO3.


SULPHONATION REACTOR

The reactor consists of a vertical bundle of small pipes like in a heat exchanger. The number of reaction pipes  depends from the required production capacity.


NEUTRALIZATION

The stream leaving the sulphonation reactor, after degassing through a  cyclone, is immediately sent to the neutralization unit which is slightly different in accordance with the processed feed stock.


TREATMENT OF EXHAUST GAS

The exhaust gas contains minimal amounts of SO2, unreacted SO3, and some parts of organic acid. The ESP consists of a  bundle of round tubes containing, and perfectly centred, axial electrodes.


CONTROL SYSTEM

Balchem Surfactant designs and implements performing solutions for supervision and control of continuous and batch processes in the sulphonation plants.


ANCILLARY UNITS

Balchem Surfactant is able to provide all the equipment related to a complete sulphonation plant, as brand new units, replacement of existing components or spare parts of other manufacturer machines.


SKID UNITS

Balchem can realize any type of skids units, to preassemble the process unit in the workshop and to facilitate the on-site installation.
