Title: Innovations by Zeru Berhane Tekie
Introduction
Zeru Berhane Tekie is an accomplished inventor based in Newark, DE (US). He has made significant contributions to the field of chemical engineering, particularly in processes related to gas treatment. With a total of 2 patents, his work focuses on innovative methods for handling acid gases.
Latest Patents
One of his latest patents is a process for treating acid gas in staged furnaces with inter-stage heat recovery. This process involves introducing a first acid gas into a reducing furnace to produce a first oxidized gas stream. The first oxidized gas stream is then cooled in a first heat recovery system before being introduced into an oxidizing furnace to produce a second oxidized gas stream. The second oxidized gas stream is subsequently cooled in a second heat recovery system. This method is particularly useful for acid gases produced in refineries after the treatment of sour gas or sour water. Additionally, spent acid may be fed into the oxidizing furnace as part of a sulfuric acid recovery process.
Another notable patent by Tekie is a process for scrubbing ammonia from acid gases comprising ammonia and hydrogen sulfide. This invention provides a method for removing ammonia as an aqueous salt solution from an acid gas mixture. A strong acid, such as sulfuric acid, is utilized as a scrubbing agent to convert ammonia into an ammonium salt. The control of pH and stripping, in combination with reboilers or evaporators, effectively reduces hydrogen sulfide concentration. The resulting ammonium salt can be produced as an aqueous solution, which may be crystallized to form a solid product. This ammonium salt solution or solid can be utilized as a fertilizer.
