With a total of 4 patents to his name, Cummings continues to push the boundaries of innovation in his industry.

Latest Patents

Cummings' latest patents include a process for improving the conversion of oxazolidones to alkanolamines. This innovative regeneration process allows for the conversion of hydroxypropyloxazolidone (HPOZD) to di-isopropanolamine (DIPA) and carbon monoxide (CO). The method involves combining an amine stream containing HPOZD with a caustic solution, which reacts to produce DIPA and CO. The reaction is conducted at elevated temperatures and requires a specific ratio of hydroxide to HPOZD. After the reaction, the mixture is allowed to settle, resulting in the separation of the amine phase from the caustic phase. The amine phase is then treated to remove excess cations, ensuring a clean amine is returned to the system.

Another significant patent involves a regenerable hydrocarbon filter. This process effectively removes hydrocarbons from hydrophilic solutions using an in situ regeneration method. A solution containing hydrocarbon impurities is passed through a resin bed, where the hydrocarbons are retained. The resin bed is then regenerated by passing a second liquid through it, allowing for the removal of hydrocarbons and enabling the resin to be reused.
