  • Patent number: 11959032
    Abstract: A process for steam cracking a whole crude including a volatilization step performed to maintain a relatively large hydrocarbon droplet size. The process may include contacting a whole crude with steam to volatilize a portion of the hydrocarbons, wherein the contacting of the hydrocarbon feedstock and steam is conducted at an initial relative velocity of less than 30 m/s, for example. The resulting vapor phase, including volatilized hydrocarbons and steam may then be separated from a liquid phase comprising unvaporized hydrocarbons. The hydrocarbons in the vapor phase may then be forwarded to a steam pyrolysis reactor for steam cracking of the hydrocarbons in the vapor phase.

  • Patent number: 11952550
    Abstract: A lubricant for a copper alloy die-casting die is mainly prepared by an inorganic nano-powder, an organic substrate material, and an organic resin material. In the present disclosure, the use of oil-based lubricants as a basis and the reduction of the content of oil in the lubricant yield improved oil selection and proportion, which cooperates with the corresponding higher proportion of inorganic powder material mixture and a more suitable spraying amount applied on the surface of the die to exert a good lubricating effect on products with complex and irregular shapes in the inner cavity of a die-casting die. At the same time, the production cost of the lubricant is low. Copper alloy die castings produced after a lubrication process have a high yield rate and smooth surfaces without casting defects.

  • Patent number: 11939536
    Abstract: Systems and methods for crude oil desalting technology are provided. More specifically, systems and methods for the usage of waste heat from compression to treat high salinity water are provided. The systems and methods generate recycled water streams for desalter treatment. The systems and methods can treat high salinity waters from desalters and dehydrators. The high salinity streams are introduced to the compressed gas streams, where the waste heat causes the water portion of the water streams to evaporate, resulting in a fully or near-saturated gas stream and a concentrated waste water stream. The saturated gas streams are cooled and condensed, and low TDS water is separated from the gas stream in knockout drums. The low TDS water can be reintroduced to the desalting system as wash water, generating a circular water reuse.
