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.

A mixing apparatus is for selective mixing of contents. The mixing apparatus has a body that defines an interior space. The body further has an aperture for permitting access to the interior space. The body has at least a portion that is collapsible and configured to be gripped and repositioned by a user to collapse a part of the body into the interior space to alter at least one of: the volume of the interior space; and the shape of the interior space. The mixing apparatus further has at least one mixing member located within the interior space that is configured and located so that the contents is forced against the at least one mixing member when the collapsible portion is gripped and repositioned by a user.

Mixers in microfluidic separation systems comprise multiple fluidic paths that extend from a distribution well to a mixing well. An incoming flow of solvent composition splits at the distribution well into as many streams as fluidic paths. The streams recombine at the mixing well to produce an output stream. One embodiment has fluidic paths with different dwell volumes that determine a percentage of the incoming flow flowing through each path. These dwell volumes can be targeted to attenuate a known noise characteristic in the incoming compositional flow. Another embodiment of mixer has a contoured surface disposed between the distribution and mixing wells. The paths extend from the distribution well to the mixing well through this contoured surface, each path passing through a different valley defined by opposing upwardly sloping banks. The valleys can have different dwell volumes that determine a percentage of the incoming compositional flow flowing through each valley.

The present invention relates to an inorganic solid nutritive composition comprising at least one polyphosphate and at least one source of iron as micronutrient, wherein said composition is water-soluble and comprises an iron content of between 0.1% and 5% by weight of iron relative to the total weight of said solid composition.

The second water jet pump comprises a driving inlet in fluid communication with the delivery pump, a suction port in fluid communication with the discharge port, and an outlet in fluid communication with the mixing inlet.

This invention pertains to a process for manufacturing an iron-based nutrient composition comprising at least the steps of supplying an iron source and a phosphate source containing at least one polyphosphate, further comprising a mixing step of the iron source with the phosphate source. The iron source and phosphate sources being in their solid phase, the mixing of the two being solid-solid mixing, leading to the obtaining of a water-soluble, iron-based solid nutrient composition.

The present disclosure describes a method and a system of producing a fire suppression medium. The method includes introducing a solvent and an alkali metal or a salt of the alkali metal into the mixer and dissolving the alkali metal or the salt of the alkali metal in the solvent to create an alkali metal solution. The method also includes filtering and analyzing a sample of the alkali metal solution. If the filtered alkali metal solution does not have a sufficient alkali metal content, the method includes introducing and dissolving additional alkali metal or the salt of the alkali metal into the alkali metal solution. If the filtered alkali metal solution has the sufficient alkali metal content, the method includes filtering the alkali metal solution to remove residual alkali metal or residual salt of the alkali metal to create and collect a saturated alkali metal solution.
