White Paper: High Active Aqueous-Based Pour Point Depressants and Wax Inhibitors

Paraffins present in crude oil can gel or precipitate, which can cause pipeline and production system blockages. These flow assurance challenges can result in production and process downtime and increased frequency and costs of workover operations.

The oil and gas industry have relied on conventional wax inhibitor chemistries, which have limited solubility in organic solvents—leading to extremely low active concentrations and requiring high dosage rates in treatment formulation; this could result in higher Opex direct and indirect costs.

Dow’s ACCENT wax inhibitors are high-active, aqueous-based chemistry, that efficiently control paraffin deposition in pipelines, with up to three times the active ethylene vinyl acetate component, resulting in lower dosage treat rates.

This white paper details the following:

  • ACCENT performance in inhibiting wax in variety of crudes

  • Comparative results versus solvent-based products with less volume of product required at equivalent active levels

  • Freeze protection capability for cold climates

  • Thermal stability and material compatibility for the oil field
