Title: William C. Petterson: Innovator in Olefin Recovery and Natural Gas Processing
Introduction
William C. Petterson is a notable inventor based in Missouri City, TX (US). He holds a total of 5 patents that showcase his contributions to the fields of olefin recovery and natural gas processing. His innovative methods have significantly impacted energy efficiency in chemical processing.
Latest Patents
One of Petterson's latest patents is an olefin recovery method. This method describes a process for recovering olefins by condensation from the reaction effluent stream of a cracking furnace. The process employs a membrane separator to reject hydrogen from the reaction effluent stream, thereby increasing the dew point temperature and reducing the energy required for refrigeration during olefin condensation. The method includes primary condensation, vapor-liquid separation, and membrane hydrogen rejection steps, followed by cascaded chilling and vapor-liquid separation steps. The recovered condensate is processed in a demethanizer to separate light end components. Additionally, an olefins plant utilizing a membrane separator for hydrogen rejection is disclosed to enhance energy efficiency and facilitate plant capacity expansion.
Another significant patent by Petterson is a natural gas liquefaction pretreatment process. This method involves pretreating a natural gas stream using a single scrub column to remove freezable C.sub.5+ components, resulting in a liquefied natural gas (LNG) product that is easy to handle and ship. The process feeds a natural gas stream to a feed point on a scrub column, where heavy components are absorbed using a liquid reflux that is free of C.sub.5+ components. The reflux stream can be overhead vapor condensate at approximately -40°C, or a combination of methane-rich LNG and vapor condensate.
