Our technology is now being sold in the form of customized Wet (Air) Oxidation Plants, fully engineered and manufactured in-house.
We have sold numerous Wet (Air) Oxidation plants in the Oil & Gas sector, where they treat wastewater coming from refining or petrochemical processes, also known as Spent Caustic Wastewater.
3V Tech's Wet Oxidation is the technology of choice for treating particularly stubborn and polluting compounds in industrial wastewater streams, which are present in a wide range of production processes, and where the use of traditional biological treatment alone is not enough.
Operations are performed on a continuous 24 hours cycle. There are no. 2 scheduled stops per year (usually one in summer and one in winter)
Electrical consumption is mainly related to electrical pumps for oxygen injection and liquid waste pumping into through the process
Provided by the combustion process, depending on COD of the incoming stream
Process Heat is recovered to dry the inorganic fraction
The architecture of the process allows for easy expandability of the plant capacity through installation of new Process modules that provide:
Treatment of almost unlimited quantity of different streams.
TOP® - Wet Oxidation for Wastewater has a high performance long track record on a wide variety of waste streams:
The Wet Oxidation process produces low temperature (40-60 °C) gaseous emission (about 10-12% by mass with respect to an incinerator). Reaction gases are cooled and washed, the incondensable gases are burned in a heater. Gas emission from TOP plant are very low, since the gases discharged are substantially carbon dioxide produced during the reaction and oxygen fed in excess with respect to the COD converted.
The gases discharged by the plant are only carbon dioxide produced during the reaction and oxygen fed in excess with respect to COD converted. The reaction gases are cooled and washed before leaving the oxidation plant. Reaction conditions (temperature, pH, etc..) do not allow the formation of any hazardous substances (eg. Dioxins).
Unlike incineration, Wet Oxidation process operates at much lower temperatures and in aqueous medium; the inorganic residue leaves the plant suspended in the liquid effluent and it is recovered by conventional decantation and filtration
High degradation of organic substances either dissolved or suspended. Liquid effluent totally biodegradable.
Bidegradability of residual COD: Example of wastewater coming from nitration of aromatic compounds.
The metals contained in the feeding (no other metals are added such as catalysers for example), at the operating conditions of the process, precipitate as oxides, so the content of such metals in the liquid effluent is drastically reduced.
Inorganic residue of Wet Oxidation treatment becomes TOP Filler, raw material that can be used to build roads. Additional processing can lead to SpheraPor & MicroPor.
Spherapor is a Lightening Structuring material; it is characterized by an open porosity almost nothing as the surface of the sphere shows vitrified. This feature prevents water absorption, whatever the application in which Spherapor is used, thus ensuring the high lightness of the final product. Mechanical strength up to 5 times higher than that of the reference products on the market it is combined with the low specific gravity; lightness and mechanical strenght, as well as a very high chemical inertness, make Spherapor a highly innovative solution for Lightweight Concrete, or Glue, markets particularly for the building field.
TOP® - Wet oxidation technology allows total chemical compounds destruction.
