The present invention provides a novel thermal filtering system and method for making such a thermal filtering system to filter out external temperature fluctuations within an enclosure. In accordance with one aspect of the invention the system includes an external insulation layer, an internal insulation layer, and a layer of phase change material located in between and thermally in series with the layers of insulation.

Thermal filtering system

A method of estimating pH titration curves for use in the adaptive control of pH in a process, comprises gathering data points which each represent the ratio between a reagent added to the process and a flowrate to the process at a measured pH, storing the data points in a bin system according to pH, and using the stored data points to create a model of the titration curve for use in controlling the addition of reagent. Older points are replaced by newer points during the process to continuously update the model. The model was used to generate a gain schedule for operating a PI controller that is used in adding a reagent to the process.
