METHOD FOR DETECTING AND CONTROLLING THE FORMATION OF HYDRATES AT ANY POINT IN A LINE IN WHICH POLYPHASIC PETROLEUM FLUIDS CIRCULATE

摘要

method for detecting and monitoring hydrate formation at any point of a pipe carrying fluid multiphase oil.we use a compositional code to simulate the terms and conditions of movement at any point on the line,in view of the fact that the fluid mixture is substantially in equilibrium at every instant.the composition of the mixture 20 is variable along the length of the pipe, and the mass of each component of the mixture is defined generally by a conservation equation of the mas.regardless of its status is.we detected the thermodynamic conditions of formation of hydrates, after adjustment for a particular combination of pseudo components of petroleum fluids so as to isolate the components, trainers of hydrates, with definitions for each of a mass fraction and a number of physical parameters and characteristics, is applied to the modules.the data for these particular fractions, in order to determine all the temperature (td) of hydrate dissociation.we can also use a control body (c) for comparing the temperature of the fluid in the oil temperature (td), dissociationand implement under the control of the supervisory body (c), of the measures taken to combat the formation of hydrates. applications of oil production in deep water, for example.
