  • Coke mitigation in hydrocarbon pyrolysis
    Patent number: 11254877
    Abstract: Methods and systems for using temperature measurements taken from a compact insulated skin thermowell to optimize a pyrolysis reaction are provided. In the present systems and methods, the upstream temperature and the upstream pressure of a pyrolysis reactor is measured through an adiabatic restriction in the inlet manifold of a parallel tube assembly to provide an absolute upstream temperature and an upstream pressure. The downstream temperature of the pyrolysis reactor is also measured following an adiabatic restriction to provide an absolute downstream temperature. The downstream pressure is then determined by multiplying the absolute upstream pressure with the quotient of the downstream temperature divided by the upstream temperature as taken to the power of k/k?1, where k is the ratio of fluid specific heat at constant pressure (Cp) to fluid specific heat at constant volume (Cv).

  • Alkylation process with improved octane number
    Patent number: 11225614
    Abstract: An improved alkylation process with improved octane number and lower final boiling point. Further, the present disclosure comprises an alkylation system that allows flexibility in the operating parameters without loss of productivity. This enhances the advantage of the solid acid alkylation process of the invention over the liquid acid processes, as the C9+ alkylate will mainly contain the desired highly branched paraffin's in the case of solid acid alkylation. By fractionation of C9+, the RON number of the gasoline alkylate after fractionation remains very high, while the final boiling point of the gasoline fraction will decrease, improving value and blending flexibility.
