Title: The Innovative Contributions of Donald M. Harrel

Introduction

Donald M. Harrel is a notable inventor based in Houston, TX, who has made significant contributions to the field of oil well technology. His innovative approach to addressing the challenges associated with salt water concentration in oil extraction has led to the development of a unique patent.

Latest Patents

Harrel holds a patent for a "Self-contained oil well salt water concentration system." This invention outlines a method for effectively concentrating salt water that is separated from an oil-water mixture produced from a well. The process involves introducing salt water into a recirculating weir, where it is mixed with more concentrated brine. The brine is then recirculated through a thermal syphon apparatus, which includes passing the brine into a boiler vessel. Within this vessel, the brine is heated to a boiling temperature, generating steam that escapes from the weir. The system operates at atmospheric pressure, and the density of the brine is monitored to ensure optimal concentration levels. The concentrated brine is subsequently released into a holding vessel, enhancing the efficiency of oil extraction processes.
