Latest Patents

One of Russell's notable inventions is the method for producing sulfonated asphalt. This process involves heating asphaltic material with a softening point between approximately 315°F and 350°F. It requires mixing the asphalt with a solvent, such as hexane, followed by sulfonation with a liquid sulfonating agent, like liquid sulfur trioxide. The sulfonic acids generated undergo neutralization with a basic agent, such as sodium hydroxide. The innovative process includes a series of steps for solvent separation, recovery for reuse, and drying the sulfonated asphalt through a drum dryer. It is primarily designed as a batch-type process, carefully coordinated within a predetermined time cycle.

Additionally, Russell's contributions extend to the realm of drilling fluid technology. He has developed an improved aqueous drilling fluid that exhibits enhanced thinning properties. This is achieved by incorporating a first agent made of a mixture that includes sulfoalkylated tannin and a polyvalent metal complex with lignite. The innovation may also combine a second agent, which consists of a soluble metal compound from elements such as chromium, titanium, iron, zinc, strontium, or magnesium.
