Technology to Convert, Concentrate, or Dry Oil-Based Emulsions, Dispersions, or Liquids Into a Dry Powder Form

A company supplies a variety of chemicals, including inverse emulsions that consist of a very-high-molecular weight, water-soluble polymer dispersed in a continuous oil phase. The typical ratio of the key components is approximately 1:1:1 (polymer:water:oil). The company seeks to convert these emulsions to a water-soluble, powdered form, without losing any of the polymer properties. The problem is particularly difficult due to the oil in the emulsion. The oil is an aliphatic hydrocarbon with a low vapor pressure (0.023 kPa at 20ºC) and a distillation temperature of 255ºC.
