  • Highly random addition bypolymers for destabilization of complex emulsions in crude oil blends
    Patent number: 11920092
    Abstract: The present invention is related to the use of ethylene alkanoate-alkyl acrylate bipolymers with a high randomness monomers distribution, which are synthesized by semicontinuous emulsion polymerization process, characterized because it is carried out using slow addition rate of the pre-emulsion feeding ({dot over (q)}?0.009 kgL·L?1·min?1), stabilized this last one by alkyl glycol ether type surfactants, at temperatures higher than 75° C. and with solids contents above 25 wt %, which avoids the formation of large sequences (blocks) of a same monomer. This structural characteristic gives the ethylene alkanoate-alkyl acrylate bipolymers a high efficiency as chemical agents for removal of complex water/crude oil emulsions of crude oil blends.

  • Frequency to digital converter, asynchronous phase sampler and digitally controlled oscillator methods
    Patent number: 11437980
    Abstract: A ?? frequency to digital converter includes digital feedback to an accumulator in a ring phase calculator that provides the converter output, which reduces implantation complexity. Digital gain correction is applicable to dual mode ring oscillator converters and charge pump converters, provides compensation for forward path gain error and eliminates the need to include analog gain correction in feedback. Asynchronous sampling includes correction logic to compensate for arbitrary initial conditions. A digitally-controlled oscillator (DCO) control technique causes the DCO frequency to increase or decrease by changing the state of one its frequency control elements at a time.

  • Multi-rate DEM with mismatch noise cancellation for digitally-controlled oscillators
    Patent number: 10735005
    Abstract: A digital fractional-N phase locked loop (PLL) with multi-rate dynamic element matching (DEM) and an adaptive mismatch-noise cancellation (MNC) is provided. The PLL includes a phase error to digital converter and a digital loop filter to suppress quantization noise of the phase error to digital converter and drive a digitally controlled oscillator. A digitally controlled oscillator (DCO) with a multi-rate DEM encoder includes an integer bank of frequency control elements (FCE) and a fractional bank of frequency control elements. Adaptive mismatch-noise cancellation logic operates to cancel DCO phase error arising from frequency control element (FCE) static and dynamic mismatch error by estimating ideal MNC coefficient values during PLL normal operation, estimating MNC coefficient errors at each sample time, and updating the MNC coefficient values to approach zero (FCE) static and dynamic mismatch error.
