Latest Patents
One of her latest patents is a fixed-bed catalytic reactor. This invention discloses a fixed-bed, catalytic reactor wherein reaction heat can be exchanged against a heat exchange medium circulating indirectly through the catalyst bed. The reactor comprises a catalyst bed with internally embedded banks of heat exchange tubes. An inlet distributor is designed to distribute reactants for flow through the bed, allowing the distributed fluid to pass through in a flow path where a catalytic reaction occurs. The reaction effluent is collected from the bed by an outlet product collector. The heat exchange medium circulated through the internal heat exchange tubes adds or removes reaction heat as required for enhanced conversion in the reactor. Multiple heat exchange tubes can be utilized, and inlet and discharge manifolds are provided for distributing the circulating heat exchange medium. The spacing of the heat exchange tubes can be adjusted according to the heat interchange required to optimize the reaction rate.
Another notable patent is a process for producing urea. This urea production process combines lower pressure urea concentration and carbamate recovery steps into a single non-vacuum operation. Following high-pressure stripping, a bulk of unreacted carbamate is recovered from the reaction effluent. The remaining carbamate is stripped by heated air at atmospheric pressure, allowing urea to be concurrently concentrated without the use of vacuum evaporators. The weak carbamate solution formed is stripped of water using air and steam at a medium pressure single tower hydrolyzer/stripper to obtain a concentrated carbamate stream suitable for recycling to the reactor. This process employs heat integration for enhanced energy efficiency and produces a high-quality aqueous condensate suitable for direct use as boiler feed water, eliminating the need for additional cooling and ammonia treatment. The process also simplifies and reduces unit operations to cut costs.
