Course Credit: 0.1 CEU, 1 PDH

Deposition of inorganic and organic solids in production systems compromises throughput and can cause other operational and safety issues. Once formed, remediation of deposits is costly, often resulting in lost production. Solids management strategies typically involve a combination of chemical injection, thermal management and periodic chemical or mechanical remediation operations specific for each depositing species. Internal coatings offer another potential approach to solids management. In this presentation, we evaluate the performance of a highly hydrophobic diamond like carbon (DLC) coating on deposition of common production system solids. The coating is a 200-nanometer thick functionalized amorphous DLC coating that is molecularly bonded to the substrate through a plasma deposition process. The impact of the coating on deposit formation and adhesion is investigated through use of bench scale, pilot scale and field scale experiments for wax, asphaltene, inorganic scales and hydrates. Based on the positive results of the performance testing, a commercial-scale application facility has been designed, constructed and in commercial operation.
