Abstract: In a process and apparatus for treating produced water, the produced water flows through a series of treatment units. A portion of the produced water may by-pass one or more of the treatment units but the by-pass portion may be such that the treated water is still acceptable, for example for discharge or reuse. Concentrations of oil and grease, organic carbon, silica, pH or related parameters in the produced water may be monitored and used to control the process or apparatus. Control of the process may involve one or more of altering a by-pass portion, altering the addition of chemicals, and altering the operation of a unit process. The process may be controlled to respond to upset conditions, or such that the concentration of one or more limiting contaminants is near, but not over, a specified maximum for re-use or discharge.

Abstract: A combination power plant and intensified farm includes a power plant and an intensified farm. The power plant generates electricity and an exhaust stream. An exhaust cleanup facility captures CO2 from the exhaust stream. The intensified farm receives at least a portion of CO2 from the exhaust cleanup facility to assist in the raising of at least one crop. If necessary, the intensified farm receives at least a portion of electricity from the power plant. In another embodiment, the exhaust cleanup facility also provides H2O to the intensified farm. In another embodiment, a NOx to fertilizer conversion facility converts NOx from the exhaust cleanup facility to a fertilizer and provides the fertilizer to the intensified farm. In another embodiment, a gasifier or digester receives an inedible biomass from the intensified farm and converts the inedible biomass to a fuel, which is to the power plant.

Abstract: A system for treating produced water, for example from a SAGD bitumen production operation, has a treatment unit using chemical oxidation (CO) or electromagnetic treatment (ET) to destroy or degrade organics in the produced water. The treatment module may use CO or ET in combination with biological treatment or sorption processes or both. When the treatment module is used upstream of a steam generator, it reduces fouling in the steam generator and in any blowdown water treatment device. A brine concentrator or a crystallizer may be used to treat the blowdown water. The treatment module may be used in combination with a nanofiltration (NF) or reverse osmosis (RO) membrane filter. Optionally, the produced water may be treated with an ET process such as microwaves directly upstream of a steam generator or upstream of a concentrator or crystallizer in a blowdown water stream.

Abstract: Systems and methods for removing organic contaminants from water may be used, for example, to treat produced water from a steam assisted heavy oil recovery operation. The treated produced water may be re-used to create steam. Alternatively, the produced water may be a blowdown stream treated to facilitate further treatment in a thermal crystallizer. The treatments may include pH adjustment or separating de-solubilized organics or both. Other treatments may include one or more of oxidation, sorption and biological treatments. The treatments may be used alone or in various combinations. One exemplary combination includes reducing the pH of produced water, separating de-solubilized organics from the produced water, and oxidizing the produced water or contacting the produced water with activated carbon.
