TREATMENT AND RECYCLE OF LANDFILL LEACHATE INTO EVAPORATORS OF AN IN SITU HYDROCARBON RECOVERY OPERATION

摘要

Techniques for reprocessing waste water streams derived from hydrocarbon production operations can include determining characteristics of the streams and units of a zero or reduced liquid discharge (ZLD/RLD) system, selecting streams and reprocessing units of the ZLD/RLD system, and recycling the streams into the ZLD/RLD system. The streams can include landfill leachate derived from ZLD/RLD sludge, and the units of the ZLD/RLD system can include an evaporator. Selected recycle streams can be recycled into an evaporator and a crystallizer based on silica content of the streams. Advantages such as facilitating operational enhancements in the ZLD/RLD system, reducing fresh water requirements, enhancing the use of the ZLD/RLD system, managing the risk of scale formation in reprocessing units, and reducing costs of alternative waste water disposal can be facilitated.
