    (5) DEEMULGER COMPOSITION The invention relates to the preparation of oil, namely to the compositions used to separate water-containing oil emulsions. Water-in-oil oil emulsions are refined by the addition of small amounts of surfactants. In order to achieve optimal separation, i.e. to obtain, under the conditions of each particular case, in the shortest possible time, complete separation of the phases with the lowest salt and water content in the oil, as well as the lowest oil content in the water for different compositions of oils and their different production conditions, requires the use of different surfactants in as demulsifying agents. It is known to use demulsifying compositions based on blocks of copolymers of alkylene oxides, for example oxyalkylated, including ethoxylated, polypropylene glycol L1. However, the known demulsifying agent has insufficient demulsifying ability. Also known is a demulsifier composition containing products of the reaction of diisocyanates with oxyalkylated, for example hydroxylated or oxypropylated alkyl phenol formaldehyde resin and ethoxylated with polyalkylene glycol 2. The disadvantage of the demulsifier of this composition is its unsatisfactory demulsifying ability. The purpose of the invention is to increase the demulsifying ability of the composition. The goal is achieved by the fact that the composition of the demulsifier for the separation of water-containing oil emulsions or oily sludge, containing a genic demulsifier of the type of block polymers of ethylene oxide and
    A. A block polymer prepared by adding 27 moles of ethylene oxide to 1 mole of propylene glycol with an average molecular weight of 1900.

    to 1 mole of polypropylene glycol with a molecular weight of 1900.
    C. The product obtained by stitching 235 weight.h. ethoxylated nonylphenol formaldehyde resin, which is obtained by reacting p-nonylphenol with a slightly larger one,
    than an equimolar amount of formaldehyde, and the addition of 5 mol of ethylene oxide to 1 mol of resin, which has a molecular weight corresponding to about 5 times the nonylphenol formaldehyde unit with 300 parts by weight. block copolymer A and 125 weight.h. common / Iogo toluene diisocyanate at YO170 C for 1 h (prototype).
    R. A resin splitter obtained by reacting p-nonylphenol with a slightly greater than equimolar amount of formaldehyde in the presence of sodium hydroxide and then adding 10 mol of propylene oxide and 2 mol of ethylene oxide to 1 mol
    nonylphenol formaldehyde resin, the molecular weight of which corresponds to approximately 5 times the unit nonyl phenyl formaldehyde.
    PRI me R 1. For the demulsification experiments, crude oil (Brunei field) containing itO vol.% Of water is used. Comparative tests of the de-emulsion effect of the following demulsifiers are carried out at i <5 ° C.
    The neutral surfactant salt (s) is the salt of dodecylbenzenesulfonic acid and the product of the addition of 8 mol of ethylene oxide to 1 kgule of oleylamine (25 wt.) + Demulsifier A (75 wt. |.).
    Demulsifiers are used in the amount of 350 million dollars each. in the form of 65% solutions in methanol. The deemulatory effect each time after a separation time of 10, 30, BO and 120 minutes is evaluated by measuring the separated part of the water, the intermediate layer of sludge and the clear oil. At the same time, the blank test is carried out without the addition of a demulsifier. The results of comparative tests are given in table 1. -,
