FIELD: oil and gas production. ^ SUBSTANCE: here is disclosed mobile module unit for utilisation of oil slime and rejects of oil and gas processing. The unit consists of functional blocks: block of control over process, power block, block of raw stock reception and preparation, demulsification and treatment block, block for cleaning excess water, and block for storage and pouring commodity products to consumers. The distinguished feature of the unit is like follows: the unit is made in form of separate mobile modules each equipped with their proper trailing facilities thus forming a train or railroad train with platforms whereon there are secured functional blocks. The blocks are furnished with corresponding fasts securing them to vehicles and with hoisting machines. The said functional blocks are distributed along train of modules in sequence with process for utilisation of rejects. The train of modules can be operatively started up on site. Also, the said module of demulsification and treatment includes the block of preliminary demulsification and hydro-acoustic treatment and the block of main demulsification and hydro-acoustic treatment. The block for excess water cleaning includes the block of excess water cleaning from residues of commodity product and its pneumatic-acoustic treatment and the block of excess water cleaning from mechanic impurities and its pneumatic acoustic treatment. Each of four said blocks for treatment of working medium is equipped with an acoustic cavitation mixer made in form of a cased mechanism with branches for supply and export of process flows of working mixture of emulsion and water. Inside the mixer there is installed an acoustic generator in form of a stationary hollow cylinder with acoustic generating channels-cavitators. Their geometric dimensions and shape correspond to properties and volume of process flows of working mixture in composition of main - prepared mixture and additional medium - water from the blocks of preliminary and main treatment and air - for the blocks of excess water cleaning. The said acoustic generator with its upper part is connected at least with two confusers forming an ejector in the point of their connection for mixing main mixture and additional medium, while with its lower part the said acoustic generator is connected to a diffuser. The block of preliminary demulsification divides prepared mixture to excess water with mechanical impurities and prepared product with insignificant content of water and mechanical impurities. The block of main demulsification and hydro-acoustic treatment performs thermo-chemical demulsification at flushing with hot water and divides prepared product to commodity product and excess water with insignificant content of mechanical impurities. The block for cleaning excess water from rejects of commodity product and its pneumatic-acoustic treatment divides mixture into a floating layer and excess water with mechanical impurities. The block of cleaning excess water from mechanical impurities and of its pneumatic-acoustic treatment divides mixture to excess water and mechanical impurities in form of a suspension. ^ EFFECT: increased efficiency of processing, upgraded quality of production and efficiency of process for division of raw stock to phase constituents; implementation of given process for raw stock divided by standard processes of de-emulsification with difficulty. ^ 6 dwg |
