  • Deasphalting and hydroprocessing of steam cracker tar
    Patent number: 10570342
    Abstract: Systems and methods are provided for solvent deasphalting of steam cracker tar. The resulting deasphalted oil produced from the steam cracker tar can then be hydroprocessed, such as hydrotreated and/or hydrocracked in a fixed bed reactor. The solvent deasphalting can correspond to a mild or trim deasphalting or can correspond to solvent deasphalting at higher solvent to oil ratios. Performing a trim deasphalting can reduce or minimize the amount of deasphalting residue that is formed as a product from the deasphalting process.

  • Sequential deasphalting for base stock production
    Patent number: 10550341
    Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

  • Detection of corrosion rates in processing pipes and vessels
    Patent number: 10502677
    Abstract: For a monitored corrosion sensor, such as a sensor based on one or more mechanical oscillators disposed in a fluid flow, one or more values are measured over time. The values can be measured at a desired frequency, such as a once per second, once per minute, or another convenient frequency. The measured data can then be analyzed as a time series. The goal of the analysis is to identify variations in the time series data that are sufficiently unexpected relative to the prior behavior of the time series within a given time window. The identified variations can then, for example, be excluded from consideration when determining a corrosion-related value for the sensor.
