CO2 Corrosion Rate Prediction for Submarine Multiphase Flow Pipelines Based on Multi-Layer Perceptron

On Coupling Co2 Corrosion and Multiphase Flow Models

Corrosion prediction in multiphase flow has been a challenging task in oil and gas industry for many years. Strictly speaking, the existing mechanistic CO2 corrosion models can only be used in single-phase flow. To add the capability of predicting corrosion in multiphase flow, the mass transfer and the turbulent diffusivity correlations in the models have to be modified to properly calculate th...

Effects of Multiphase Flow on Corrosion Inhibitor

This paper investigates the inhibition performance of a typical imidazoline based inhibitor under multiphase flow. Electrochemical impedance spectroscopy (EIS) measurements were carried out in a 101.6 mm I. D.,15 m long acrylic flow loop using ASTM substitute saltwater and carbon dioxide gas. This flow loop system can generate slug flow, fill pipe flow and other multiphase flow patterns. Effect...

An Extension of Multi-Layer Perceptron Based on Layer-Topology

There are a lot of extensions made to the classic model of multi-layer perceptron (MLP). A notable amount of them has been designed to hasten the learning process without considering the quality of generalization. The paper proposes a new MLP extension based on exploiting topology of the input layer of the network. Experimental results show the extended model to improve upon generalization capa...
