SPRAY DRIED EMULSIFIER COMPOSITIONS, METHODS FOR THEIR PREPARATION, AND THEIR USE IN OIL-BASED DRILLING FLUID COMPOSITIONS

摘要

Spray dried emulsifier compositions are described, which have desirable emulsifying and wetting characteristics. Among other advantages, the solid particulate emulsifier compositions greatly reduce transportation costs and simplify the logistics and environmental concerns associated with shipping large volumes of solvent-containing liquids. The emulsifier comprises (1) a carboxylic acid terminated fatty amine condensate or (2) a modified tall oil or (3) a blend of (1) and (2) that is converted to its alkali or alkaline earth metal salt and spray dried.

主权项

1. A method for making a spray dried emulsifier, comprising:
neutralizing an emulsifier comprising a modified tall oil to produce a neutralized emulsifier; and spray drying the neutralized emulsifier to produce a spray dried emulsifier.
