  • Patent number: 11897803
    Abstract: This Invention Patent application provides a comprehensive program for control of organic and inorganic contaminants from paper production processes and other potentially pollutant industries through the integrated action of three continuous treatment systems, referenced herein as “3WAY”, with a first system aimed at the treatment of process waters for reuse, more specifically “white or clarified water” present in the “wet end” of paper and cellulose machines, allied to a second system based on the use of an adsorbent clay mix equipment that enables treatment of the cellulose pulp in previous phases of the process up to the machine circuit, in addition to a third system that carries out the cleaning of contaminant deposits present in clothing (felts and wires) or other machine parts through application of a heated and pressurized cleaning solution with a high detergency power.

  • Publication number: 20220058317
    Abstract: This Invention Patent application refers to a smart process control system for continuous treatment of paper and cellulose machine clothing and parts, in which three machine learning methods are covered, comprising learning and predictive algorithms especially developed for constant evaluation of the knowledge base, aiming at operational optimizations, online monitoring of relevant parameters through use of IoT (Internet of Things) for detection of faults and opportunities, in addition to modeling of ideal operation conditions through directed statistical simulations. The synchronism of this artificial intelligence cycle enables automatic decision making on the best chemical and mechanical strategy for application, aiming at the best possible performance.

  • Publication number: 20210148051
    Abstract: This system is intended for paper and cellulose manufacturing process, in order to enable partial or full talc replacement in controlling pitch and stickies, in addition to helping in retention and drainage in paper and cellulose manufacturing processes. The chemical methodology and processes employed herein primarily involve the mix of adsorbent clays such as bentonite and hydrotalcite in the form of a slurry mix, obtained through a thermodynamic equipment called continuous flow shearing chamber (502), which provides delamination in pressure and temperature conditions, able to enhance the exposure of adsorption sites.
