  • Publication number: 20240110110
    Abstract: Processes and systems for quenching an effluent. In certain embodiments, the process can include contacting a pyrolysis effluent and a first quench medium to produce a first quenched effluent. A bottoms stream that can include tar and an overhead stream that can include ethylene and propylene can be obtained from the first quenched effluent. The first quench medium can include a first portion of the bottoms stream that can include a first portion of the tar. In certain embodiments, the process can also include hydroprocessing a second portion of the bottoms stream that can include a second portion of the tar to produce a hydroprocessed product. A hydroprocessed bottoms stream can be obtained from the hydroprocessed product. In certain embodiments, the process can also include contacting at least a portion of the hydroprocessed bottoms stream and the first portion of the bottoms stream to produce the first quench medium.

  • Patent number: 10894925
    Abstract: A multi-stage process for upgrading tars is provided. A predominantly hydrotreating stage can be applied before a cracking stage, which can be a hydrocracking or a thermal cracking stage. Alternatively, a predominantly cracking stage, which can be a hydrocracking or a thermal cracking stage, can be applied before a hydrotreating stage. Apparatus suitable for performing the method is also provided.

  • Patent number: 10597592
    Abstract: A process is described for upgrading pyrolysis tar, such as steam cracker tar, by hydroprocessing in the presence of a utility fluid. The hydroprocessing conditions comprise a pressure >8 MPa and a weight hourly space velocity of combined pyrolysis tar and utility fluid >0.3 hr?1 and are selected so that the hydrogen consumption rate is in the range of 270 to 445 standard cubic meters/cubic meter (S m3/m3) of pyrolysis tar.
