Abstract: A process for performing high temperature reactions includes introducing reactants into a reactor vessel, generating a high temperature within the reactor vessel, exposing a first portion of the reactants to the high temperature, and reacting the first portion of the reactants based on contact with the high temperature to produce one or more products. The high temperature is higher than a lower temperature of a wall of the reactor vessel, and a temperature gradient is generated between the high temperature and the lower temperature of the wall. A second portion of the reactants are not exposed to the high temperature, and the second portion of the reactants do not react.

Abstract: A method for determining and identifying corrosion protective layers that provide corrosion protection against crude oils and crude oil fractions is disclosed. The method identifies naturally occurring constituents in crude oils that indirectly provide corrosion protection. A method assessing the potential of these constituents is also disclosed. The method includes exposing metal coupons with the crude oil or crude fraction of interest at the expected operating temperature of concern. The corrosion potential assessment further analyzes the exposed coupons with transmission electron microscopy and an additional high temperature exposure that challenges the tenacity of the protection offered by the corrosion protective layer.
