Current logistics and pipeline-infrastructure limitations make transportation and production of waxy crude oil challenging, necessitating a step change in the chemistry required to mitigate crude-oil-composition issues. For wax prevention, pour-point depressants (PPDs) or wax inhibitors usually are used. A new approach makes use of a special hydrophobe modification in typical polymer systems that significantly broadens the systems’ applicability.
Introduction
Several wax-control strategies are available in the oil industry. Waxy crude oils are sometimes mixed with a diluent to avoid deposits.
