Title: J George Hayden: Pioneering Innovations in Lignin Treatment

Introduction

J George Hayden, an inventive mind from Awendaw, South Carolina, has made significant contributions to the field of chemical engineering with a total of six patents. His work primarily focuses on improving processes related to lignin treatment, showcasing his commitment to advancing sustainable practices in the industry.

Latest Patents

Among his latest innovations, Hayden has developed a patent for a process for treating lignin that enhances the production of granular lignin from black liquor. This invention introduces several improvements, including the incorporation of a pre-carbonation column that effectively reduces CO2 flow into the carbonation column’s sparger by lowering the pH of black liquor to approximately 12. The process also optimizes the coalescing of droplets into a liquid-lignin phase by strategically placing the exit of the carbonation column at or slightly beneath the interface. Additionally, operating the carbonation settler under low pressure while transferring liquid-lignin to a high-pressure acidification reactor enables the recycling of vent gas back to the pre-carbonation column. The invention also provides a design for a vent gas absorber.

Another significant innovation was in tall oil refining. Here, he proposed a warm water loop for cooling tall oil heads fraction, replacing the conventional cold water method. This innovative approach prevents condensation and the resultant solidification of athraquinone pulping aid, mitigating fouling within cooling towers. The system's temperature is automatically controlled by adjusting cold water flow and removing excessively warm water as necessary.
