Analysis of Effect of Pressure on Separator Pressure Vessel Design using PV Elite Software

Pipeline plays a vital role in transporting water, gas and oil from one place to another. Over the years, several failures have been reported in pipeline mainly due to aging (i.e., corrosion). The failure occurs when the stresses in a pipe segment due to applied loads exceed the capacity of the pipe. Therefore, it is important to predict the realistic pipe stress at the design and assessment stages to ensure the safety across the entire lifetime. As significant portion of the pipeline is buried in the underground in most of the occasions, the soil-structure interaction analysis is important as part of the stress analysis. Depending on the location of the network, the pipe will be subjected to varying levels of traffic and pressure loads that need to be accurately determined in order to perform reliable pipe stress estimations. Several pipe stress prediction methods have been developed over the years and reported in the literature. However, these methods are either analytical or empirical based models. The former uses the structural mechanics of the pipe by discarding the complex soil-structure interaction effect while the later fully depends on the experimental results. To overcome these problems, the numerical methods can be used to incorporate the soil-structure interaction effect more efficiently in pipe stress analysis together with traffic and internal pressure loads. In this study, the finite element method is used to analyse the pipe-soil system subjected to external traffic and internal pressure loads. Further, the model developed is used to understand the effect of soil properties, pipeline characteristics, and loading on pipe stress through sensitivity analysis. Finally, the response surface method is used to develop a new pipe stress predictive equation using the results of finite element analyses.

Stress Analysis Of Buried Pipelines

Process piping play an extremely important rolein Petroleum refineries throughout the world as a means forcarrying Hydrocarbons from one location to other. Theseprocess piping are subjected to Corrosion over a period ofoperational time, which is the destructive attack of materialby reaction with its service fluids containing corrodents suchas Sulphur, H2S, HCl, CO2, organic and inorganic acids andexternal environments thus causing a natural potentialhazard associated with oil and gas transportation facilities.Various potential damage mechanisms are identified for preheated crude inlet piping to atmospheric distillation columnusing American Petroleum Institute standardssuch as API 581and API 571. These damage mechanisms consist mainly ofHigh Temperature Sulfidic and Naphthenic acid corrosion.Corrosion rates for this damage mechanism is identified fortwo crudes namely Kuwait crude and Arab Extra Light Crudeusing API 581. Retirement thickness for this piping iscalculated using ASME B 31.3. Further remaining life of thispiping is estimated using corrosion rate, present thickness andretirement thickness of the piping.
