An apparatus and method for the treatment of stimulation fluid that involves passing a mixture of the stimulation fluid and reagents through a sectioned tank, each section having the means to agitate the mixture contained therein. Treated fluid is removed from a final settling section for reuse in oil and gas production operations.

Treatment of stimulating fluid

Polymeric supports, which have been treated with a halosulfonic acid, increase the activity of single-site catalysts used with aluminoxane co-catalysts, resulting in improved ethylene polymerization. The present invention seeks to provide polymeric catalyst supports which have been treated with halosulfonic acid for improved activity.

Halogenated organic particles for catalyst supports

A catalyst system comprises 1) a group 4 organometallic catalyst and 2) an activator comprising a solid zirconium acid component and a metal alkyl. The catalyst system is inexpensive and is highly active for the polymerization of olefins. Preferred organometallic catalysts contain a cyclopentadienyl ligand, a phosphinimine ligand and or a ketimide ligand.
