OIL PRODUCTION ADDITIVE FORMULATIONS

摘要

Petroleum additive formulations include a petroleum additive dissolved in a carrier fluid including at least one compound of the formula (I): (R<2>)p-Ph-(CH2)m-COO-(AO)n-R<1> where; R<1> is C1 to C10 alkyl; AO is alkyleneoxy; n is 0 or from 1 to 100; m is 0, 1 or 2; and Ph is a phenyl group, which may be substituted with groups (R<2>)p; where each R<2> is independently C1 to C4 alkyl or alkoxy; and p is 0, 1 or 2. Further, crude petroleum or petroleum refinery streams can be treated by adding a petroleum additive dissolved in a carrier fluid of the formula (I) to the product stream. Desirably the carrier fluid is or includes iso-propyl benzoate and/or 2-ethyl hexyl benzoate.
