Patents by Inventor Prashant Udaysinh Parihar

Prashant Udaysinh Parihar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9914104
    Abstract: Methods, apparatus and processes for three phase contacting and reactions in a cross flow reactor with reduced feed vaporization, low pressure operation, higher liquid holdup, lower reactor pressure drop, low severity operation, and reduced product inhibitory effects. A cross flow reactor for three phase catalytic hydroprocessing, having at least one reactor stage is disclosed. The reactor stage has a central gas distributor with perforated lateral surface for distributing gas, a middle region accommodating a packed catalyst bed, and an outer gas space for removal of effluent gases from the middle region. The middle region receives a liquid reactant and gas from central gas distributor to carry out three phase catalytic hydroprocessing reaction.

  • Patent number: 9846147
    Abstract: Method(s) and a system for predicting the refining characteristics of an oil sample are described. The method of predicting the refining characteristics, such as distillate yield profile, processability, product quality or refinery processing cost, may include development of a prediction model based on regression analysis. The method may further include determining the physical properties of the oil sample and predicting the refining characteristics based on the developed prediction model. The determination of the physical properties of the oil sample includes determining at least one of Conradson Carbon Residue (CCR) content, Ramsbottom Carbon Residue (RCR) and Micro Carbon Residue (MCR).
