Abstract

This disclosure includes systems and methods of operating a convection section of an furnace in a chemical production process with simulated combustion gas (SCG) that is heated by an electric or thermal energy source instead of by combustion. Some such systems and methods utilize a thermal mass that is configured to store thermal energy such that the thermal mass can be used to heat a working fluid. The thermal mass can be coupled to a heater that receives electrical energy from a renewable source, and converts the electrical energy into thermal energy to heat the thermal mass and thereby store the thermal energy. In some aspects, a furnace is in fluid communication with the thermal mass such that the furnace receives the working fluid from the thermal mass to provide thermal energy to process for chemical production that would otherwise typically be provided by flue gas from a hydrocarbon-fired radiant section in conventional systems. In some configurations, the working fluid is or comprises one or more radiatively participating gases heated to exceed a threshold above which the working fluid transfers heat through radiation.

Abstract

Systems and methods for upgrading a hydrocarbon stream to a lower boiling point hydrocarbon feed material are disclosed. The system includes a feeding device to transport a hydrocarbon stream that includes an alternative feedstock. The hydrocarbon stream is partially cracked in a first cracking unit producing a lower boiling point hydrocarbon feed material, a catalyst rich heavy hydrocarbon stream, and coke. A slurry settler receives the catalyst rich heavy hydrocarbon stream and coke and separates the catalyst from the catalyst rich heavy hydrocarbon stream thereby defining a catalyst rich stream and a heavy hydrocarbon stream. A coking vessel receives the heavy hydrocarbon stream and coke and separates the heavy hydrocarbons from the coke thereby defining a heavy hydrocarbon stream. Finally, a second cracking unit that receives the lower boiling point feed material from the first cracking unit and produces olefins and aromatics.

Abstract

An emulsion polymerization process of manufacturing a graft polymer composition with a reduced residual monomer content includes feeding a vinyl aromatic monomer, an unsaturated nitrile, and a first portion of an initiator to a reactor having a temperature of 50 to 63° C., the reactor containing an initial reaction system comprising water and a diene emulsion. After 10% to 35% of the first portion of the initiator has been added, the reactor temperature is increased to 65 to 85° C. The polymerization reaction runs for 0 to 30 minutes, then a second portion of the initiator and a third monomer are added, and the reaction is allowed to proceed for a second non-charging reaction time to produce the graft polymer composition. In the process, the vinyl aromatic monomer and the unsaturated nitrile are fed to the reactor in 10 to 40 minutes. The process time can be less than 145 minutes.
