Abstract: A method for processing of oil-containing materials consists in subsequent realization of technological processes, according to which the apparatus is preliminary prepared, which is manufactured mainly of cylindrical shape and has a compression chamber of round cross-section, heating device, parcels/bags, made of filter fabric, and holed elements in form of perforated disks, which have form, which corresponds to the form of cross-section of inner cavity of the body of pressing machine, and at the same time the feedstock is prepared – oil-containing material of plant raw material type, filter powder, FUZ, soap stock, pearlites, diatomites, or the mixture of the mentioned materials in any combination and percentage ratio in the finished mixture, and the technological process is continued by supply of the mentioned raw material into heating devices, and the heating of feedstock is realized to the temperature of +20- depending on its grade/type, during heating the intimate mixing of feedstock is realized, the packaging of feedstock-oil-containing material into parcels/bags, made of filter fabric, is realized; filled parcels/bags are situated into pressing machine one by one along the direction of pressing, the mentioned holed elements are installed between each of the parcels/bags; the parcels/bags filled with feedstock are pressed, and the finished product is obtained at pressure buildup in pressing machine in a form of oil and pressed rests of feedstock; during closing stage of technological process for processing of oil-containing materials the collection of obtained oil into oil catchers is realized, and collected oil is subjected to final purification, at that, at realization of the process for pressing of parcels/bags filled with feedstock, the pressure buildup is realized to the value not above 300 MPa, and the final purification of oil is realized by means of additional filtering, or by means of freezing oil. At preparation of pressing machine the stiffening plates are made on the inner surface of its compression chamber, which are directed sideward the apical axis of the body of pressing machine and located along the mentioned axis along the whole length of body of the mentioned pressing machine, at preparation of holed elements the mentioned holed elements are made in form of perforated disks having the width of no less than 10…25 mm with subsequent stretching by filter fabric, during closing stage of realization of technological process for preparation of feedstock the purity of prepared feedstock – oil-containing material, is controlled; during realization of technological process for heating and mixing of feedstock the additional technological stages are realized consistently, according to which the addition of zeolites to the feedstock is realized, and at realization of the mentioned stage the intimate mixture is obtained, which is formed at mixing of feedstock and zeolites; the quality control of homogeneity of the mentioned mixture and its physicochemical parameters is realized during realization of technological process for packaging of feedstock oil-containing material, into parcels/bags, and the mixture, obtained at mixing of feedstock and zeolites are packed into mentioned parcels/bags; during realization of technological process for location of parcels/bags into pressing machine for theirs subsequent compression the parcels/bags, filled with the mixture, obtained at mixing of feedstock and zeolites, are located into pressing machine; during realization of technological process for compression of parcels/bags is realized at special maximal level of pressure of parcels/bags with mixture, obtained at mixing of feedstock and zeolites, the exposure of mentioned parcels/bags is realized under mentioned pressure during no more than 20 minutes; during realization of technological process for preparation of stock in a form of oil the preliminary purification of obtained oil is realized, after ending of realization of the process for preparation of stock in a form of oil and by-product in form of compacted rests of mixture of feedstock and zeolites, obtained at first compression, the collection of mentioned compacted rests of mixture of feedstock and zeolites is realized for recurrent compacting; after ending of realization of technological process for final purification of oil the parameters of obtained oil, which went through the purification, are controlled; after ending of the first stage of processing of oil-containing materials the arrangements for determination of rests of uncompressed oil in mixture of feedstock and zeolites in compressed rests, obtained at the first pressing, are made; at determination of rests of uncompressed oil in compressed rests of mixture of feedstock and zeolites, obtained at the first pressing, the technological operations are sequentially realized, according to which the arrangements for grinding of compressed rests of feedstock are primarily made; after ending of realization of technological process for grinding of compressed rests of feedstock the mentioned grinded rests of feedstock are supplied into heating device, and heating of grinded rests of feedstock is realized into heating device to the temperature of +40…50C according to previously defined technology; at heating of grinded rests of feedstock theirs intimate mixing is realized; the second adding of zeolites is realized during heating and mixing of grinded rests of feedstock with obtainment of corresponding mixture; after ending of technological process the obtainment of intimate mixture, formed at mixing of grinded rests of feedstock and zeolites,the quality control of homogeneity of the mentioned mixture and its physicochemical parameters is realized, the localization of mixture of grinded rests of feedstock and zeolites into percels/bags is realized, made of filter fabric; parcels/bags with mixture of grinded rests of feedstock and zeolites are located into pressing device one by one along the direction of pressing with subsequent installation of holed elements between each of parcels/bags according to previously defined technology; and the process for pressing of parcels/bags with mixture of grinded rests of feedstock and zeolites is realized with pressure buildup to 400…500 MPa according to previously defined technology are obtained again; at pressure buildup in pressing device to the maximal value of 400…500 MPa, the feedstock in a form of oil and pressed rests of feedstock are obtained again; the collection of obtained oil into oil collectors is realized at second compression of parcels/bags with mixture of grinded rests of feedstock and zeolites; the oil, obtained at second compression, subjected to final purification with application of technological processes, applied at purification of oil, obtained at first compression; the oil, obtained at first compression and oil, obtained at second compression, are poured together and intimate mixed; the parameters of oil, obtained by pouring of oils, obtained respectively at first and second compression of feedstock; after ending of second stage for processing of oil-containing materials the arrangements for determination of rests of uncompressed oil in the mixture of feedstock and zeolites, obtained at second compressing are made for decision making about necessity of realization of the next stage of compression of oil from the rests of mixture of feedstock and zeolites.
