Treatment technology

Cleaning technology The whole division is serviced by the service company INTRA, located in Samara. The most advanced technologies, modern equipment and materials are used for cleaning. Applied technologies allow cleaning of pipes and equipment with sediments that take up to 100% of the cross section. SCOPE OF TECHNOLOGY: Cleaning tanks, tanks; Cleaning heat exchangers (heaters, boilers, oil and air coolers, condensers, evaporators, etc.); Cleaning the cooling jackets of the compressor cylinders of gas pumping and compressor stations; Cleaning of ABO gas sections of all types; Cleaning steam and hot water boilers; Purification of distillation columns. Go EQUIPMENT: The company has the equipment to perform all types of cleaning: electrohydropulse installation; tank trucks; hot water boilers; high pressure apparatus Go APPLICABLE CLEANING TECHNOLOGIES Sandblasting - allows you to clean the surface from scale, rust, old paint. Mobile sandblaster installations are used to ensure the processing of any difficult shaped surfaces, to give the surface the necessary appearance and characteristics - unnecessary materials are removed, the surface of the material is hardened and becomes prepared for coating. Mechano-cavitation cleaning is carried out with the help of the device “Tornado” and is performed by cutting heads or brushes with water supply through hollow rods. The special design of the cutting heads allows you to drill the deposits with concrete strength. The best option when removing sediments occupying more than 50% of the area of ​​boiler tubes and heat exchangers. Also, mechanical cleaning is carried out using a high-performance single-brushing system for feeding and rotating the BRLM ramrod, an effective way of cleaning tube bundles from viscous deposits (tar, bitumen) using high-pressure hot water, while controlling the rotation and feeding of the ramrod with a remote control, which increases safety hot water works; beams from viscous deposits (tar, bitumen) using hot water of high Hydrodynamic cleaning is an effective way to remove impurities and solid deposits formed on the internal surfaces of pipelines of any length and configuration of the process equipment. The principle of operation of installations based on the use of water flow, which is supplied under high pressure. Remnants of scale removed from internal surfaces are effectively washed out with the help of high-pressure installations - the treated surface is smoother than after machining (drilling, shot blasting, etc.). In many cases, hydrodynamic cleaning is an alternative to the overhaul of equipment and communications, being many times more economical. Hydrochemical cleaning - The chemical cleaning procedure consists in forcibly circulating a technical detergent (TMS) along the flushing circuit, which allows achieving high quality cleaning and contributes to an increase in the equipment's service life. EXPERIENCE OF PERFORMED WORKS Purification of the RVS with a volume of 5000 m3 from under the vacuum gas oil with the remaining sludge of 225 m3. The full complex of works was completed in 11 days. (Customer schedule 21 days); Work was completed on cleaning six RVS with a volume of 5000 m3 and a total volume of sludge residue of more than 900 m3 within 30 working days (according to a schedule of 60 days); From 2012 to 2014, one of the refineries cleaned up 62 RVS with volumes from 2,000 m3 to 20,000 m3, and more than 20,000 m3 of oil sludge was removed; Work was carried out on cleaning the heat exchange equipment on the AVT-1 unit. A total of 26 heat exchangers with a diameter of 800 to 1,400 mm and a length of 6,000 mm and 42 ABO sections were served. According to the customer’s schedule, the deadline was 18 days. Applying a new highly efficient equipment, the time was reduced to 12 days without compromising quality; From 2012 to 2014, during the complex repairs, 848 heat exchangers Ø = from 400 to 1600 mm and 509 ABO sections were serviced; Work on cleaning heat exchangers in the amount of 42 units, with a total length of 75138 meters. The work was carried out in winter at a negative temperature of -25 ° C. Mobilization on call was 24 hours.
