Systems and methods are provided for performing steam cracking on a feed while using direct heating of the reaction environment. The heating of the reaction environment can be achieved in part by transporting heat transfer particles from a heating zone to cracking zone. This can be performed in a fluidized bed reactor, a moving bed reactor, a riser reactor, or another type of reactor that can allow for catalyst movement and regeneration during operation.

Fluid bed steam cracking using direct heating

Methanol-to-gasoline conversion may be performed using a heavy gasoline treatment, followed by a separation operation. Methanol may be converted into a first product mixture comprising dimethyl ether (DME) under DME formation conditions. In a methanol-to-gasoline (MTG) reactor, the first product mixture may be converted under MTG conversion conditions to produce a second product mixture comprising light gasoline hydrocarbons and untreated heavy gasoline hydrocarbons. The untreated heavy gasoline hydrocarbons may be separated from the light gasoline hydrocarbons and transferred to a heavy gasoline treatment (HGT) reactor. The untreated heavy gasoline hydrocarbons may be catalytically reacted in the HGT reactor to form a third product mixture. A heavy hydrocarbon fraction may be separated from the third product mixture. The heavy hydrocarbon fraction includes heavy gasoline hydrocarbons having a lower boiling endpoint than does the untreated heavy gasoline hydrocarbons.

A method for identifying sensor drift can include: setting an autocorrelation threshold for a sensor in a long-short term memory (LSTM) model developed based on historical process measurements from an analogous sensor to a sensor; collecting measured data from the sensor; applying the LSTM model to the measured data from the sensor, wherein applying the LSTM model comprises: applying the LSTM model to the measured data from the sensor to yield LSTM predicted data; calculating key performance indicators (KPIs) of the LSTM data based on an accumulated slow drift error (ASDE) model, wherein the KPIs comprise an error, an accumulated prediction error, an accumulated slow-drift error, and an estimated autocorrelation; and identifying sensor drift when the estimated autocorrelation violates the autocorrelation threshold.

Systems and methods are provided for conversion of methanol to gasoline in an integrated system that can also upgrade light paraffins generated by the methanol conversion process to aromatics. In some aspects, the integrated configuration can include integration of the stage for upgrading of light paraffins to aromatics into the product separation sequence for processing of the methanol conversion effluent. In other aspects, the integrated configuration can further include sharing a common catalyst between the methanol conversion stage and the stage for upgrading light paraffins to aromatics.

Processes for converting an organic-material-containing feed comprising contacting the feed with a plurality of fluidized hot particles in a pyrolysis zone to product a first pyrolysis effluent, optionally contacting the first pyrolysis effluent with a quenching stream to impart additional pyrolysis of organic materials contained in the quenching stream, separating at least a portion of the particles and feeding them to a combustion zone where the particles are heated to an elevated temperature, optionally contacting the combustion zone effluent with a second organic-material-containing stream to produce, e.g., syngas, and feeding at least a portion of the heated particles to the pyrolysis zone.

Methanol-to-gasoline (MTG) conversion may be performed with forward methanol processing. Methanol may be fed to a first reactor where it may be catalytically converted under dimethyl ether formation conditions in the presence of a first catalyst to form a product mixture comprising dimethyl ether (DME), methanol, and water. The DME may be separated from the methanol and the water and delivered to a second reactor. In the second reactor, the DME may be catalytically converted under MTG conversion conditions in the presence of a second catalyst to form a second product mixture comprising gasoline hydrocarbons and light hydrocarbon gas. The methanol and the water from the first reactor may be separated further to obtain substantially water-free methanol, which may be delivered to the second reactor. The separation of methanol from the water may be performed using the light hydrocarbon gas to effect stripping of the methanol.

Methanol-to-gasoline (MTG) conversion may be performed with a methanol recycling. Methanol may be fed to a first reactor where it may be catalytically converted under dimethyl ether formation conditions in the presence of a first catalyst to form a product mixture comprising dimethyl ether (DME), methanol, and water. The DME may be separated from the methanol and the water and delivered to a second reactor. In the second reactor, the DME may be catalytically converted under MTG conversion conditions in the presence of a second catalyst to form a second product mixture comprising gasoline hydrocarbons and light hydrocarbon gas. The methanol and the water from the first reactor may be separated further to obtain substantially water-free methanol, which may be returned to the first reactor. The separation of methanol from the water may be performed using the light hydrocarbon gas to effect stripping of the methanol.

Systems and methods are provided for integrating a fluidized coking operation, a reverse osmosis operation, a coke gasification operation and/or processes for production of compounds from the synthesis gas generated during the coke gasification. Conventional FLEXICOKING&#x2122; processes may produce carbon dioxide emissions and low Joule Flexigas, as well as waste water containing metals and poor quality coke containing metals, which may be expensive to process, or may require sending to other facilities for further processing. The systems and methods described herein address these issues in an advantageous and economical manner, with improved carbon capture, waste upgrade and chemicals production, while providing high value ash (e.g., for recovery of metals such as vanadium, nickel, sodium, iron, and mixtures thereof) and upgraded coke streams.

Systems and methods are provided for using an oxygen-containing gas as at least part of the stripping gas for the stripping zone or section in a fluidized coker. By using an oxygen-containing gas as the stripping gas, heat can be added to the stripping zone selectively based on combustion of coke and/or hydrocarbons with the oxygen in the stripping gas. This can allow the temperature of the stripping zone to be increased relative to the temperature of the coking zone of a fluidized coking system. The flow of oxygen can be controlled to achieve a desirable temperature in the stripper while the reactor temperature is independently set by preheating of the feed and/or hot coke circulation to the reaction zone.
