Abstract
Изобретение относитс к сорбционным способам очистки поверхности воды от аварийных разливов нефти. Целью изобретени вл етс сокращение расхода сорбента.сокращение времени очистки и уменьшение обводненности удал емой нефти. Дл осуществлени способа используют измельченный каучук с пол рными группами, например, нитрилакриловой, метакриловой кислот, размеры фракции не более 3-5 мм. Эти каучуки в отлИчие от бутадиенстироль- ного каучука, который используетс в известном способе, сохран ют свои эластичные свойства при многократном использовании сорбента и тем самым обусловливают повышение эффективности предложенного способа. Способ обеспечивает по сравнению с известным решением сокращение -времени очистки до 10 - 20 мин' при коэффициенте поглощени ~3,0 г/г нефти и уменьшение содержани воды в выдел емой нефти до 2 - 5%. 1 з-п. ф-лы.2 табл.слThe invention relates to sorption methods for cleaning the surface of water from emergency oil spills. The aim of the invention is to reduce the consumption of sorbent. To reduce the cleaning time and reduce the water content of the oil to be removed. For carrying out the process, crushed rubber with polar groups, for example, nitrilacrylic, methacrylic acid, is used, the size of the fraction is no more than 3-5 mm. These rubbers, in contrast to styrene-butadiene rubber, which is used in the known method, retain their elastic properties with repeated use of the sorbent and thereby cause an increase in the efficiency of the proposed method. The method provides, in comparison with the known solution, a reduction in the purification time of up to 10-20 minutes with an absorption coefficient of ~ 3.0 g / g of oil and a decrease in the water content of the recovered oil to 2-5%. 1 sp. f-ly.2 tabl.sl
Description
Изобретение относитс к нефтегазодобывающей промышленности и может быть использовано дл очистки повер хностй воды от аварийных разливов нефти.The invention relates to the oil and gas industry and can be used to clean the surface of water from emergency oil spills.
Цель изобретени -сокращение времени дл очистки, сокращение расхода сорбента и уменьшение обводненности удал емой нефти.The purpose of the invention is to reduce the time for refining, reducing the consumption of sorbent and reducing the water content of the oil being removed.
Поставленна цель достигаетс тем, что в способе очистки поверхности воды от неф ти, включающем нанесение крошкообразного сорбента на основе каучука с последующим его механическим сбором, в качестве сЬрбента используют каучуки с пол рными группами, например, нитрилакриловой, метакриловой кислот и других, и размером фракций не более 3,0 - 5,0 мм.Каучуки с пол рными группами, в отличие от каучуков без пол рных групп (Например , каучук полибутадиенстирола, который используетс в известном способе), способны сохран ть свои эластичные свойства в углеводородной, в частности, нефт ной среде . Следовательно, предложенные типы каучуков не будут подвергатьс значительной деформации после их отжати дл многократного использовани . Каучук бутадиенстирола и подобные ему подвергаютс деформации до такой степени, что их многократное использование практически нецелесообразно .The goal is achieved by the fact that the method of cleaning the surface of water from oil, including the application of a rubber-based sorbent based on rubber followed by its mechanical collection, uses rubbers with polar groups, for example, nitrilacrylic, methacrylic acids and others, and the size of fractions not more than 3.0 - 5.0 mm. Couplings with polar groups, unlike rubbers without polar groups (for example, polybutadiene styrene rubber, which is used in a known method) are able to retain their elastic properties in a hydrocarbon, in particular petroleum medium. Therefore, the proposed types of rubbers will not undergo significant deformation after they have been pressed for repeated use. Butadiene styrene rubber and the like are deformed to such an extent that their repeated use is impractical.
Бутадиеннитрильный каучук продуг г совместной полимеризации бутадиена и нитрилакриловой кислоты, получаемой в водной эмульсии. Содержание нитрилакриловой кислоты в полимере колеблетс в пределах от 17 - 20 в СКН-18 до 36-40% в СКН-40.Butadiene nitrile rubber is produced by the joint polymerization of butadiene and nitrilacrylic acid obtained in an aqueous emulsion. The content of nitrilacrylic acid in the polymer ranges from 17-20 in SKN-18 to 36-40% in SKN-40.
П р и м е p. В эксикатор с диаметром 14 см внос т 76,9 мл нефти из месторождени Нефт ные Камни. После растекани нефти образуетс пленка толщиной 5 мм. Затем нанос т 20 г каучука марки СКН-40 фракции 2,0 - 3,0 мм. Через 20 мин контакта нефти с сорбентом последний удал ют с поверхности и методом взвешивани определ ют коэффициенты поглощени , который составл ет 2,6 г/г. Нефть из сорбента удал ют путем отжима (до 60%). Сорбент многократно используют дл очистки поверхности воды при таких же услови х. Результаты приведены в табл.1 - 2.PRI m e p. To a desiccator with a diameter of 14 cm, 76.9 ml of oil from the Oil Stones deposit are introduced. After spreading oil, a 5 mm thick film is formed. Then 20 g of SKN-40 rubber of fraction 2.0 to 3.0 mm are applied. After 20 minutes of contact of the oil with the sorbent, the latter is removed from the surface, and the absorption coefficients are determined by weighing, which is 2.6 g / g. Oil from the sorbent is removed by pressing (up to 60%). The sorbent is repeatedly used to clean the surface of water under the same conditions. The results are shown in table.1 - 2.
