Title: Nayif A Rasheedi: Innovator in Carbon Dioxide Recovery Technologies

Introduction

Nayif A Rasheedi is a prominent inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of carbon dioxide recovery and organic compound extraction. With a total of 3 patents, his work focuses on improving efficiency in environmental technologies.

Latest Patents

Rasheedi's latest patents include innovative processes for cyclone separation and recovery of carbon dioxide from heated liquid absorbents. This process enhances the efficiency of regenerating a CO-rich liquid absorbent stream after it has absorbed CO from a flue gas stream. The method involves passing pressurized liquid sorbent through a heating zone to reach desorption temperatures, followed by introduction into a cyclone separation zone. This results in a more rapid and efficient separation of CO from the liquid sorbent. The CO-lean liquid sorbent is then recycled back to the absorption zone, while the CO is processed for storage or downstream use.

Another notable patent involves methods for recovering organic heteroatom compounds from hydrocarbon feedstocks. This process utilizes a contactor to mix hydrocarbon feedstock with an aqueous solvent, forming an extraction mixture. The solvent, created from pressurized carbon dioxide and water, selectively forms a complex with organic heteroatom compounds. By adjusting the recovery temperature and pressure, the solvent complex can be decomposed to recover the organic compound.
