  • Publication number: 20240158705
    Abstract: The present disclosure provides a method and device for refining waste plastic pyrolysis oil, the method including (S1) subjecting a waste plastic pyrolysis oil feedstock to a heat treatment by charging the waste plastic pyrolysis oil feedstock into a rotary kiln reactor and increasing a temperature of the rotary kiln reactor to form a product; (S2) recovering a gas component from the product of step (S1); (S3) separating a high boiling point wax component from the recovered gas component and re-supplying the separated high boiling point wax component to the rotary kiln reactor in step (S1); and (S4) recovering refined oil from the gas component from which the high boiling point wax component is removed.

  • Patent number: 9554753
    Abstract: An electrocardiogram (ECG) sensor includes a motion artifact detector configured to detect a motion artifact component from a first channel signal of a first channel and a second channel signal of a second channel using a channel offset coefficient. The channel offset coefficient indicates a difference between the first channel signal and the second channel signal. The ECG sensor includes an ECG filter configured to generate an ECG signal by performing a least mean square (LMS) filtering operation on the first channel signal to remove the motion artifact component.
