Abstract: The invention generally relate to processes, systems, and methods for the pyrolysis of hydrocarbon feeds containing one or more forms of mercury, e.g., the steam cracking of heavy oil, such as crude oil. Effluent from the pyrolysis is processed to remove various forms of mercury produced during the pyrolysis and/or carried over from the hydrocarbon feed.

Abstract: In a process for making a copolymer, a first product stream comprising a semi-crystalline polymer and a chain terminating agent is produced in a first reactor system. The first product is provided to a second reactor system wherein a low crystallinity polymer is produced in the presence of the semi-crystalline polymer. At least a portion of the chain terminating agent is removed from the second reactor system by an in-situ process.
