The other direction is more promising, involves the development of new industrial processes which would let do without environmentally hazardous products (including side) or to reduce their use of and exposure to a minimum. Significant branch of the modern chemical industry is the production, used in the processes of the oil and oil transportation. Below we consider some classes of oilfield chemicals and provides examples of available commercial products, including meeting the requirements of "Green" chemistry. Demulsifiers One of the major classes of reagents used in the preparation of oil demulsifiers are presented today anion (cation) active and nonionic surfactants, such as block copolymers of ethylene oxide and propylene oxide, ethoxylated amines, higher fatty alcohols, alkylphenols, etc. 3.
Even with a relatively small reagent consumption (40-100 g / t) rather acute problem of waste disposal surface-active substances produced by many thousands of tons of the modern chemical industry. In this light, demulsifiers were obtained on the basis of wood chemical product manufacturing – tall oil, but their effectiveness was lower than that of demulsifiers based on ethoxylated fatty acids 4. On the basis of xylitol (derived from waste cotton plants) and synthetic fatty acids was obtained by a non-ionic demulsifier 5, which showed a result of industrial tests of high efficiency. Corrosion inhibitors are the most diverse classes of organic and inorganic compounds, most of which is synthetic, not occurring in nature 6. It is obvious that the negative impact on the biosphere biologically hostile, recalcitrant compounds can not be overestimated, especially when using a wide range of or other agent, so constantly being developed new corrosion inhibitors that would benefit differed from the existing not only the efficiency of inhibition, but also environmental safety.
