The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

The present disclosure relates to a microfluidic device including a microfluidic substrate and dry reagent-containing particles. The microfluidic substrate includes an ingress microfluidic channel that fluidly feeds an egress microfluidic channel through a microfluidic-retaining region that includes a microfluidic discontinuity feature, a particle-retaining chemical coating, or a combination thereof. The dry reagent-containing particles include a reagent that is releasable from the dry reagent-containing particles when exposed to a release fluid. The dry reagent-containing particles are retained within the microfluidic substrate at the microfluidic discontinuity feature or particle-retaining chemical coating in position to release the reagent into the egress microfluidic channel upon flow of release fluid from the ingress microfluidic channel through the microfluidic-retaining region.
