DOI: 10.24887/0028-2448-2018-4-100-103
Key words: oil pipelines, petroleum product, asphaltene-resin-paraffin deposits, laboratory research, solvents for asphaltene-resin-paraffin deposits, cleaning, technical solutions, linear part of oil pipelines, technological pipelines, evaluation the quality of cleaning, quality indicators
Authors: Ya.M. Fridlyand (The Pipeline Transport Institute LLC, RF, Moscow), M.N. Kazantsev (The Pipeline Transport Institute LLC, RF, Moscow), F.V. Timofeev (The Pipeline Transport Institute LLC, RF, Moscow), S.N. Zamalaev (The Pipeline Transport Institute LLC, RF, Moscow)

The article presents a generalization of the Transneft’s experience in increasing the volumes of oil products transportation by substitution excess capacity of oil pipelines by oil-products pipelines. To implement this program, the Pipeline Transport Institute has developed and implemented a number of technical solutions including the procedure for cleaning the internal surface of the linear part of oil pipelines and oil pumping stations technological pipelines form oil residues and asphaltene-resin-paraffin deposits; selection of effective chemical solvents for asphaltene-resin-paraffin deposits according to the results of experimental studies; methodology for assessing the readiness of pipelines to petroleum products transport by analyzing the changes in quality characteristics of reference petroleum products. When pipelines did not undergo special treatment the main reason of the change in oil products quality during transportation is their interaction with oil residues and asphaltene-resin-paraffin deposits on the internal surfaces of pipelines. To ensure the cleaning tube walls from the deposits for each section of the oil pipeline we carried out an analysis of the composition and structure of deposits. According to this analysis result chemical solvents were selected and tested in laboratory conditions for the development of well-founded technical solutions. Technical decisions on treatment of the linear part of the pipelines and oil pumping stations technological pipelines provided complex approaches depending on operations conditions. For cleaning the linear part of pipelines along with chemical reagents pigs were applied. In case of itechnological pipelines usage of chemical reagents was combined with equipment steaming. As a results 2450 km of pipelines, 10 oil pumping stations and 2 oil depots of seaports were prepared to transportation of oil products.
