Title: The Innovative Contributions of Alexander Db Daspit
Introduction
Alexander Db Daspit is a notable inventor based in Dallas, TX (US). He has made significant contributions to the field of oil re-refining through his innovative patents. With a total of 2 patents, Daspit has focused on developing processes that enhance the quality and usability of used oil.
Latest Patents
Daspit’s latest patents include a "Method of Rerefining Waste Oil by Distillation and Extraction." This process involves recovering a base oil of lubricating viscosity from used oil by distilling it in apparatus with multiple theoretical plates. Impurities are extracted from the lube range distillate fraction using a liquid extractant, such as N-Methyl-2-Pyrrolidone (NMP), at controlled temperatures. The oil and extractant are then separated, allowing for the reuse of the extractant and further treatment of the oil for targeted applications.
Another significant patent is the "Process for De-Chlorinating and De-Fouling Oil." This invention aims to reduce the chlorine content of oil and its tendency to foul during distillation. The process heats the oil to temperatures between 400 to 700°F and contacts it with a non-oxidizing gas, such as steam, for several minutes. This method prepares the oil for subsequent distillation or finishing into a base lubricating oil or other distillate products.
