Latest Patents

One of Cho's latest patents is titled "Process for continuous recovering (meth) acrylic acid and apparatus for the process." This invention relates to a method and apparatus for the continuous recovery of (meth)acrylic acid. The process involves conducting gas phase oxidation of compounds such as propane and propylene in the presence of a catalyst to produce a mixed gas containing (meth)acrylic acid. The mixed gas is then quenched to remove high boiling point by-products, followed by contacting it with water to obtain an aqueous solution of (meth)acrylic acid. Finally, the solution is purified to yield high purity (meth)acrylic acid. This innovative method significantly reduces energy consumption and enhances production efficiency compared to previous recovery methods.
