摘要： A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.

摘要： A fossil-fuel-fired system, which includes an emissions-control-agent dispenser, a furnace, an emissions monitor and, optionally, a controller, is disclosed. The emissions-control-agent dispenser provides a prescribed amount of organic-emissions-control agent, such as, for example, an opacity-control agent to the fossil-fuel-fired system. The furnace includes an exhaust communicating with the atmosphere. The emissions monitor is capable of measuring at least one property of the flue-gas communicated through the exhaust to the atmosphere. For example, when an organic-emissions-control agent is an opacity-control agent, the emissions monitor has the capability of at least measuring opacity. When included, the controller communicates with at least the emissions-control-agent dispenser and the emissions monitor.
