Ballestra Neutrex system

In order to change over from 27% SLES to 70% SLES in the Ballestra Neutrex system (see also figure 47), the following procedure is recommended (see also figure 33) ... 

All equipment allows production of 40% active alkylbenzene sulphonate and 30% active sodium lauryl alcohol sulphate products. Normally, the equipment also allows production of other products such as high active (50-60%) all lbenzene sulphonate and 70% AD ethoxylated alcohol sulphates. Specially designed neutralisers of this kind yield products such as 75% AD sodium coconut alcohol sulphate. All these q>tions also hold for the Ballestra Neutrex system discussed in section 5.6.3. 

The Ballestra Neutrex SV system (Fig. 10) has been developed to obtain, in a single process step, products with high AM at high purity. Neither solvents nor hydrotropes (sometime used to overcome viscosity and consequent high-pressure problems in the loop) are required to operate with these highly viscous products.
