Title: Innovations by Inventor Louis D Friedman in Coal Processing
Introduction
Louis D Friedman, a prominent inventor based in New Brunswick, NJ, has made significant contributions to the field of coal processing with four patents to his name. His innovative approaches have played a crucial role in advancing technologies related to coal gasification and carbonization.
Latest Patents
Among his latest patents, the "Process for Controlling Sulfur Oxides in Coal Gasification" stands out. In this innovative method, a fluidized coal gasification process employs heat generated from a recycle combustor residue sourced from a slagging combustor. By contacting the flue gas with incoming coal feed, sulfur dioxide (SO₂) is effectively removed and converted into hydrogen sulfide (H₂S) within the gasifier, enabling the recovery of sulfur in a Claus Plant. Another notable invention is "Fluidized Coal Carbonization," which describes a multi-stage process for carbonizing coal to produce oil, gas, and char. In this technique, oil-containing vapors from the first stage are utilized as the fluidizing gas, effectively drying incoming coal feed while maintaining the vapor pressure below 10 mm to prevent condensation.
Career Highlights
Throughout his career, Louis D Friedman has been associated with esteemed companies like Cogas Development Company and FMC Corporation. His work in these organizations underscores his commitment to enhancing coal processing technologies and addressing environmental concerns related to coal usage.
Collaborations
Friedman has often collaborated with notable professionals in the industry, including his coworker Ralph Tracy Eddinger. Their combined expertise has fostered innovative solutions in the field of coal processing.
Conclusion
Louis D Friedman’s contributions to coal gasification and carbonization have not only led to the development of advanced processes but have also paved the way for a more sustainable approach to utilizing coal resources. His patents continue to influence the industry, reflecting his dedication to innovation and environmental stewardship.
