1To the main vessel add liquids of phase A, start mixing and disperse the alkylate polymer with strong mixing for 20-30 minutes.
2Heat this dispersion with gentle mixing to 55-60 °C, add phase B to it, and mix until dissolved.
3To a secondary vessel add phase C, start mixing and heat to 55- 60°C. The add phase D and mix until uniform.
4When both phases are homogeneous and at their designated temperatures, add phase CD to phase AB.
5Strongly mix, without aeration, phase ABCD for three minutes and then start to cool it.
6When this batch is below 50°C add phase E with mixing, replace any water lost and mix until smooth.
