Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Configuration for olefins production

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.

Process for mixing dilution steam with liquid hydrocarbons before steam cracking

A method for thawing and removing frozen material from a cryogenic separation unit such as that found in an olefin production plant comprising employing a flushing agent to thaw and remove the frozen material, purging the flushing agent with a gas, and removing residual flushing agent with a solvent that is miscible with the flushing agent and has a freezing temperature substantially lower than the flushing agent.

Method of thawing a cryogenic unit

A method for forming a synthesis gas with a tailored hydrogen/carbon monoxide ratio that is optimized for use in a downstream process wherein membrane gas separation is employed to form a hydrogen rich stream and a separate synthesis gas product which has a tailored hydrogen/carbon monoxide ratio.
