Approaches and design for zero-flaring in refineries

Abstract

Gas flaring is the controlled high temperature oxidation process used to burn waste gases containing combustible components. It is unfortunately responsible for severe environmental and health problems and in this paper we will present various methods to minimize that impact. Initially, we will describe the gas flaring equipment setup and process and present the aforementioned health and environmental issues. We will then analyze the various flare gas reduction methods used in oil refineries categorized by their type of implementation. Flare gas collection and compression, gas to liquid technology, gas to solid technology, energy production, flaring reduction in operation and flaring reduction in maintenance.
