Title: Innovations of Johannes Jeichienus De Vries

Introduction

Johannes Jeichienus De Vries is a notable inventor based in Gorinchem, Netherlands. He has made significant contributions to the field of chemical processing, particularly in the area of magnesium chloride solutions. With a total of 3 patents to his name, De Vries continues to push the boundaries of innovation in his field.

Latest Patents

De Vries's latest patents include a method for processing magnesium chloride solutions and a method for manufacturing carboxylic acids. The first patent outlines a process that involves providing an aqueous magnesium chloride solution with a concentration of 10-30 wt. % to a concentration step where water is evaporated. This results in a concentrated magnesium chloride solution with a concentration of 30-50 wt. %. The process is conducted in stages, with at least one stage occurring at elevated pressure. The concentrated solution is then sent to a thermohydrolysis reactor at temperatures exceeding 300°C, where magnesium oxide (MgO) is withdrawn in solid form, and a hydrochloric acid (HCl) containing gas stream is produced. This gas stream is subsequently cooled and processed further.

The second patent also focuses on processing magnesium chloride solutions, detailing a method that begins with an aqueous solution containing 5-25 wt. % of MgCl2. This solution undergoes evaporation to remove water and organic contaminants. The resulting solution is then concentrated and treated with an HCl containing gas stream at elevated temperatures, leading to the production of MgO and HCl gas.
