Abstract: Embodiments of the invention improve the performance, safety, and efficiency of the gasification process. Embodiments of the invention improve downdraft gasification by improving upon the systems and methods for fuel preparation and by addressing gasifier bridging and channeling. Unique parts of the system include a unique hearth and grate design, a programmable logic controller and interface for managing the gasification process, an improved filtration system, a unique system for eliminating mist, a unique system for cooling gas, a unique combined flare, an integrated auger system, and a new system and method for sampling gas.

Abstract: A polymer reaction and quality optimizer that optimally determines all factors affecting the finished polymer prior to initiating the batch, uses the optimized parameters in setting up and starting the batch, in an on-line procedure for correcting assumptions made in the optimal determination based upon measurement responses from batch startup, and in an on-line procedure that periodically executes to determine and adapt reactor temperature control profiles across the remaining life of the batch to achieve the desired polymer properties and optimal polymer yield. The reaction and quality optimizer also determines at the end of a batch using several criteria if any of the equipment used within the process such as the reactor should be cleaned.
