Abstract
On installation stabilize the condensation of the Orenburg gas processing plant (OGPP), OOO "Gazprom pererabotka" acute problem of deposition of asphalt-resin-paraffin deposits (ARPD) resulting in worse job of heat transfer equipment, asphalt-resin-paraffin deposits build up on the plates and in the bottom of the column stabilization, the formation of pyrophoric compounds, complicating the steaming system in the preparation of the equipment to repair. Currently, water vapor is used to clean the heat exchange equipment from the ARPD at the plant, which adversely affects the technological mode of the stabilization unit and the storage tank Park of stable condensate. In accordance with the technique of chromatographic analysis, the composition of "disulfide oil" obtained at the Orenburg gas processing plant and unstable condensate mixed with oil was determined, physical and chemical parameters were determined. An easy – to-implement Express technique is proposed to determine the solvent capacity of disulfide oil (DO). The technique does not require the use of complex instrumental methods of analysis and mathematical modeling and allows in a short time with minimal cost to determine the solvent capacity. The carried out measures on dissolution of ARPD allows to recommend to use a new type of solvent of ARPD on the basis of disulfide oil. At the same time, the tasks of both the qualified use of this by-product and the increase in the efficiency of equipment cleaning from ARPD will be solved. Disulfide oil is currently pumped into stable condensate, so its injection into expanded condensate will not violate the technological mode of operation of the condensate stabilization unit, which is confirmed by calculations.
