A system for converting waste plastic material to petrochemicals. The system including a feed inlet and distributor zone, a raked film reaction section located below the feed inlet and distributor zone, and a stirred tank reaction section located below the raked film reaction section.

Plastic pyrolysis reactor

Process and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.

Conversion of waste plastics to petrochemicals

The present disclosure relates generally to contaminant removal from gas streams. In certain embodiments, the present disclosure relates to a process for removing one or more contaminants from a gas stream via contact with a regenerable sorbent at high temperature and pressure, utilizing a unique arrangement of reactors operating in parallel.

Multiple fixed-fluidized beds for contaminant removal

A system which circulates fluidizable solid particles through a fluidized bed reactor, a fluidized bed regenerator, and a fluidized bed reducer to thereby provide for substantially continuous desulfurization of a hydrocarbon-containing fluid stream and substantially continuous regeneration of the solid particles is disclosed.

Desulfurization process

A system and process for purifying a 1,3-butadiene feedstock containing 1,3-butadiene and various impurities by first introducing the 1,3-butadiene feedstock stream to a separation column to produce an intermediate product stream containing 1,3-butadiene and residual impurities and then introducing the produced intermediate product stream through a condenser to a suitable dryer for removing residual impurities from the intermediate product stream and thereby forming a purified 1,3-butadiene stream. The separation column separates an overhead stream, containing 1,3-butadiene and impurities such as propadiene, water and oxygen, and a bottoms stream, containing impurities such as polymerization inhibitor, ethyl acetylene, 1,3-butadiene dimer, pentane and 1,2-butadiene, from the intermediate product stream which leaves the separation column in the form of a vapor side draw stream.

Purification of 1,3-butadiene

Described is a novel method by which the activity of a deactivated or partially deactivated paraffin isomerization catalyst is enhanced or reactivated. The isomerization catalyst undergoes a deactivation period followed by a reactivation period during which isomerizable hydrocarbons are simultaneously isomerized during the catalyst reactivation.
