Suitability of gas flare locations for minigas-to-liquid technology deployment in Nigeria

Abstract

Site suitability analysis for Mini Gas-to-liquid (MiniGTL) deployment was carried out for gas flaring (GF) sites, inorder to determine prospective utilisation of the natural resource. Results show that most of the GF sites have very low gas yield (81%);only 14have gas yield suitable for onshore MiniGTL deployment. One of the sites has a potential for supplying fuel to a nearby power plant, three can deliver power to the grid via cables and 6 can support local energy and allied industry development. The gas gathering from 7 hubs could capture about 81% of the total gas flared. This study identified viable economic options which could provide a sustainable approach to monetisation and management of associated gas. The findings provide information to support policy making initiatives that can solve the GF problem in the country. It is recommended that further analysis should be carried out to examine alternative scenarios and the economics of such deployment.
