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.

Monitoring and control of unit operations for generating steam from produced water

The repair compositions include a ceramic composition, a colloidal solution, an aqueous binder, an aqueous dispersant, and an aqueous ammonia solution. The ceramic composition includes a first population of yttria-stabilized zirconia particles having a mean diameter from about 250 nm to about 1000 nm, a second population of yttria-stabilized zirconia particles having a mean diameter from about 2 &#x3bc;m to about 10 &#x3bc;m, and a third population of yttria-stabilized zirconia particles having a mean diameter from about 20 &#x3bc;m to about 250 &#x3bc;m. One method includes depositing the repair layer onto the damaged region, the repair layer including the repair composition, and heat treating the repair layer.

Processes for fabricating ceramic membranes include providing a porous substrate having at least one inner channel extending therethrough and having surfaces defined by porous walls, depositing a coating slurry on surfaces of the inner channel(s), and sintering. Sintering temperatures for the processes range from about 400&#xb0; C. to 800&#xb0; C. Coating slurries for use in the processes include a boehmite sol and a colloidal suspension of porous alumina particles.

A method of coating a surface, preparing a doped metal-ion precursor solution for coating, and an article including a component coated by the described method are disclosed. The method of coating includes applying a fluoro-silane doped metal-ion precursor solution on the surface to form a coated surface. The metal-ion precursor solution includes greater than about 0.6 molar percent concentration of a metal-ion precursor in a solvent comprising an alcohol. The method of preparing the doped metal-ion precursor solution includes dissolving a metal-ion precursor in a solvent comprising an alcohol at a temperature greater than about 100&#xb0; C. and refluxing at a temperature greater than about 150&#xb0; C. such that the concentration of metal-ion precursor in the solution is greater than 0.6 molar percent of the solution, and adding a fluoro-silane to the metal-ion precursor solution.

A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.

Hybrid multichannel porous structure for hydrogen separation

A free-standing zeolite membrane and a zeolite membrane supported on a support structure are disclosed. The free-standing zeolite membrane is fabricated by mixing zeolite particles and an optional inorganic binder, forming a green body, and sintering the green body at a sufficiently low temperature so as to prevent damage to the gas selectivity properties of the zeolite particles. The supported composite zeolite membrane is fabricated by mixing a sacrificial binder, an optional inorganic binder, boehmite sol and zeolite particles to form a slurry. The slurry is then coated onto a porous support structure, dried and sintered at a sufficiently low temperature so as to prevent damage to the gas selective properties of the zeolite particles. In both membranes, the zeolite particles span the entire thickness of the membrane to provide a high selectivity path for the flow of gas to pass therethrough.
