Apparatus and process for producing hydrocarbons from biomass having a pyrolysis reactor (2) in which dry biomass (Bd) is heated in an environment substantially free from oxygen and halogens, a pyrolysis product (PP) and char (C) is produced, a gasification reactor (3) in which separated char (C) is heated in an environment containing steam (Wst) to reduce the char (C) to produce a synthesis gas (Sh), a gas cooler (4) in which the produced synthesis gas (Sh) is cooled to a cooled synthesis gas (Srt); a conditioning and pressure system (5) in which cooled synthesis gas (Srt) is refined to produce a purified synthesis gas (Sp), and a separation device (6) in which hydrogen gas (H2) is separated from purified synthesis gas (Sp). A hydrogenation device (7) into which pyrolysis oil (PO) retrieved from the pyrolysis product (PP) and separated hydrogen gas (H2) recuperated from the separation device (6) are introduced for hydrogenation in which pyrolysis oil (PO) is hydrogenated by the presence of hydrogen gas (H2), and hydrocarbons (BO) that are substantially free from oxygen are produced.

Waste, such as municipal solid waste (MSF), is separated into a wet fraction and refuse derived fuel (RDF). For example, the waste may be separated in a press. The wet fraction is treated in an anaerobic digester. The RDF is further separated into a cellulosic fraction and a non-cellulosic fraction. The cellulosic fraction is treated by pyrolysis and produces a pyrolysis liquid. The pyrolysis liquid is added to the anaerobic digester.

Systems and methods for data quality monitoring are provided. Various embodiments include a data monitoring system that integrates into a data pipeline. The data monitoring system may receive a call from the data pipeline to analyze data inputs entering the data pipeline. The monitoring system can generate metadata describing the data inputs and compare the generated metadata with previously generated metadata to determine if the data inputs are historically consistent. The data monitoring system may return a consistency measure to the data pipeline. In further embodiments, the data monitoring system can generate metadata describing data outputs from the data pipeline and compare the output metadata to previously generated output metadata. In further embodiments, the data monitoring system may operate as a read only entity in a database. The monitoring system may monitor for changes in the database and determine when adverse changes occur in the database.

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™ 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.
