摘要： A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

摘要： A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

摘要： 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.
