There are four major existing refineries as follows:

• Old Port Harcourt Refinery; capacity 60,000 bpsd commissioned in 1965.
• Warri Refining and Petrochemical Company; capacity 125,000 bpsd commissioned in 1978.
• Kaduna Refining and Petrochemical Company; capacity 110,000 bpsd commissioned in 1980.
• New Port Harcourt Refinery; capacity 150,000 bpsd commissioned in 1989.

Thus, the total installed capacity is 445,000 bpsd. These plants in the last 15–20 years had a poor operating record with average capacity utilization hovering between 15 and 25% per annum. As a result, 70–80% of the national petroleum products demand is met through import. As at 2017, the aggregate demand of petroleum products in Nigeria was equivalent to 750,000 bpsd. Hence, there is ample scope for investment in new plants and revamp of the existing ones to make them more efficient. This paper traces the history of refining in Nigeria, highlights the current poor record of capacity utilization, proffers solutions for improving their viability, and presents prospects for growth of the industry in Nigeria.

尼日利亚的炼油业：历史，挑战和前景

现有四个主要的炼油厂，如下所示：

• 哈科特港老炼油厂；1965年投产，日处理能力为60,000 bps。
• 沃里炼油和石化公司；1978年投产，日处理能力为125,000 bps。
• 卡杜纳炼油和石化公司；于1980年投产，日处理能力为110,000 bps。
• 新哈科特港精炼厂；1989年投产的150,000 bpsd容量。

因此，总安装容量为445,000 bpsd。在过去的15至20年中，这些工厂的运行记录很差，平均产能利用率每年徘徊在15％至25％之间。结果，通过进口满足了全国石油产品需求的70-80％。截至2017年，尼日利亚石油产品的总需求量相当于750,000 bpsd。因此，有足够的空间投资新工厂和改造现有工厂以提高效率。本文追溯了尼日利亚炼油的历史，强调了当前产能利用率不佳的记录，提供了提高其生存能力的解决方案，并提出了尼日利亚该行业的增长前景。
