摘要:
The invention relates to a method for forming high sp3 content amorphous carbon coatings deposited by plasma enhanced chemical vapor deposition on external surfaces. This method allows adjustment of tribological properties, such as hardness, Young's modulus, wear resistance and coefficient of friction as well as optical properties, such as refractive index. In addition the resulting coatings are uniform and have high corrosion resistance. By controlling pressure, type of diamondoid precursor and bias voltage, the new method prevents the diamondoid precursor from fully breaking upon impact with the substrate. The diamondoid retains sp3 bonds which yields a high sp3 content film at higher pressure. This enables a faster deposition rate than would be possible without the use of a diamondoid precursor.

The invention relates to a method for forming high sp3 content amorphous carbon coatings deposited by plasma enhanced chemical vapor deposition on internal surfaces and employing the “hollow-cathode” technique. This method allows adjustment of tribological properties, such as hardness, Young's modulus, wear resistance and coefficient of friction as well as optical properties, such as refractive index. In addition the resulting coatings are uniform and have high corrosion resistance. By controlling pressure, type of diamondoid precursor and bias voltage, the new method prevents the diamondoid precursor from fully breaking upon impact with the substrate.

摘要:
An electrolytic chlorine gas generating system is disclosed. The system includes an electrolytic cell generating the chlorine gas, a brine tank supplying saturated brine to the anode compartment of the cell, and an acid feed tank containing hydrochloric acid at sufficient concentration to maintain the anolyte brine at less than about pH 4.0. In operation, the brine tank contains solid sodium chloride which dissolves in the brine and replenishes the anolyte brine solution as chloride ion is consumed during electrolysis. The acid feed tank is in fluid communication with the brine tank so that the brine is maintained at a constant volume during electrolysis.

摘要:
Apparatus for clarifying produced water. A flotation chamber has a produced water inlet, a clean water outlet, and is segmented into a plurality of cells by baffles. An oil overflow compartment is in fluid communication with the upper portion of the chamber. Produced gas is introduced into each cell of the flotation chamber by porous sparger tubes creating bubbles of 100 to 1000 microns in diameter. The bubbles rise through the water removing any suspended oil particles. The gas exits through a gas outlet. The removed oil collects on the liquid surface of the produced water and overflows to the overflow compartment. Oil is removed from the overflow compartment via an oil outlet.
摘要:
A process is disclosed for removing dissolved organics from an aqueous composition, said composition comprising water, carbon dioxide and dissolved organics, and said composition having a pH of 6.5 or less and an inlet organics concentration. The process comprises the steps of feeding said aqueous composition to a centrifugal separation zone, preferably to a hydrocyclone, depressurizing said composition in said centrifugal separation zone to regasify at least a portion of said carbon dioxide. An aqueous product stream is removed from the centrifugal separation zone wherein the concentration of said organics is less than said inlet organics concentration. The process is particularly useful in the cleanup of industrial wastewater, and also for removing organics from water produced in petroleum production operations.
摘要:
A process for removing oily residues from aqueous waste streams using a cross flow filtration system in which the efficiency of a dynamic membrane system comprising a gel layer and supporting semipermeable membrane is optimized by applying a controlled shear force parallel to the plane of the membrane.
