PIGGY BACK SEPARATOR DESIGN

Abstract

A PIGGY BACK separator is a device used in industrial oil and gas applications to separate a vapor-liquid mixture into its constituent phases. The aim of this study is to size the Piggy Back, a separator placed upstream of an electrostatic dehydrator to perform gas-liquid separation. In the course of this study, we sized the Piggy Back using manual calculations in accordance with the guidelines of the main standards and codes in force today, such as API 12J. To validate the manual assessment of the separator's dimensions, a static simulation was carried out using ASPEN HYSYS® software. Using the finally approved manual sizing methodology, and taking into account the Piggy Back separator's operational data, an economic evaluation was carried out to conclude that the design was cost-effective.
