A method for producing methyl methacrylate including: a distillation step including: supplying a reaction solution, which is obtained by subjecting methacrolein, methanol, and molecular oxygen to oxidative esterification in an oxidative esterification reactor and which contains the methyl methacrylate as a reaction product, to a first distillation column located at downstream of the oxidative esterification reactor, extracting a fraction containing the methacrolein and the methanol from a medium section of the first distillation column, and extracting a column bottom liquid containing the methyl methacrylate from a column bottom of the first distillation column, wherein a concentration of the methanol in the column bottom liquid is 1% by mass or more and 30% by mass or less.

Systems and methods for crude oil desalting technology are provided. More specifically, systems and methods for the usage of waste heat from compression to treat high salinity water are provided. The systems and methods generate recycled water streams for desalter treatment. The systems and methods can treat high salinity waters from desalters and dehydrators. The high salinity streams are introduced to the compressed gas streams, where the waste heat causes the water portion of the water streams to evaporate, resulting in a fully or near-saturated gas stream and a concentrated waste water stream. The saturated gas streams are cooled and condensed, and low TDS water is separated from the gas stream in knockout drums. The low TDS water can be reintroduced to the desalting system as wash water, generating a circular water reuse.

Methods and systems for converting ammonium waste streams into certifiably Organic ammonium salts having a variety of uses in greenhouse gas-reducing activities are herein described. The resulting ammonium salt compositions can be used to enhance crop yield.

The operation of the arrangement (device) for conversion of contaminated (loaded) water with harmful substances and elements into certified ecological, healthy water, with natural cleaning without filters, is based on the production of water vapor by heating water in a stainless steel chamber and channeling (water vapor drain) of water vapor with air flow to the liquefaction system This model works without filters, membranes or chemicals and additionally is not including other harmful substances and elements that burden, pollute, infect and contaminate the environment. Ecologically it transforms the unsuitable for health water into the excellent quality healthy drinking water. Nitrates, which are converted to nitrites (NO2) when boiled in water, can be converted into one of the most potent carcinogenic compounds, nitrosamines. The arrangement (device) includes a container (Cx), with two electrodes, that communicates with the boiling chamber, to control the limits of the boiling water level, to eliminate parasitic electromagnetic fluctuations and to avoid oxidation of the two electrodes.

The system and methods described are directed to a distillation system and method having an evaporator tank with a wall surrounding an interior evaporator tank area. A non-oxidizing gas line is disposed at least partially outside the evaporator tank in communication with the interior evaporator tank area, wherein the non-oxidizing gas line introduces a non-oxidizing gas into the interior evaporator tank; the interior evaporator tank area is generally at or above an ambient atmospheric pressure.
