Latest Patents
Walker’s latest patents include a method for starting up an olefins production plant. This innovative approach allows for the startup of the plant without venting gases to the atmosphere. An artificial feed is employed in the compression zone while the furnace and quench zones remain idle. Gases from the compression and refrigeration zones are recycled to the inlet of the compression zone during startup, after which the furnace and quench zones are started up using natural feed.
Another significant patent is a method for thawing a cryogenic unit. This method involves thawing and removing frozen material from a cryogenic separation unit, such as that found in an olefin production plant. It employs a flushing agent to thaw and remove the frozen material, purges the flushing agent with a gas, and removes residual flushing agent with a solvent that is miscible with the flushing agent and has a freezing temperature substantially lower than the flushing agent.
