Evaluating crude oil chemical dispersion efficacy in a flow-through wave tank under regular non-breaking wave and breaking wave conditions.

摘要: Testing dispersant effectiveness under conditions similar to that of the open environment is required for improvements in operational procedures and formulation regulatory guidelines. To this end, a novel wave tank facility was fabricated study dispersion crude oil regular non-breaking irregular breaking conditions. This designed operation flow-through mode simulate both wave- current-driven hydrodynamic We report here an evaluation chemical dispersants (Corexit EC9500A SPC 1000) on two oils (Medium South American [MESA] Alaska North Slope [ANS]) different (regular plunging waves) tank. The assessed by measuring water column concentration dispersed droplet size distribution. In absence dispersants, nearly 8-19% test were diluted presence about 21-36% waves, 42-62% waves. Consistently, physical waves produced large droplets (volumetric mean diameter or VMD > = 300 microm), whereas created small (VMD < 50 microm). data can provide useful information developing better guidelines use improved predictive models field.
