摘要
就工厂的生产能力而言,炼油厂的安全和性能改进是至关重要的。炼油厂确实有几个关键装置,其中一个是加氢裂化装置(HCU),它主要用于石油炼油厂生产柴油和其他中间馏分。就安全性而言,维持这些产品的规定温度是一个真正的挑战。在高吞吐量时,用于冷却柴油等出口产品的冷却器失效,导致柴油温度升高,导致不安全状态和性能下降。冷却器的关键部件将使情况进一步恶化。该案例研究介绍了HCU冷却系统的过程安全和性能改进,通过安装额外的冷却器作为主动冗余来降低柴油出口温度。采用一种有效的风险评估方法FMEA (Failure Mode and Effects Analysis)来识别冷却器机组的关键部件。
Process Safety and Performance Improvement in Oil Refineries Through Active Redundancy and Risk Assessment Method - A Case Study
Safety and performance improvement of oil refineries are of paramount importance as far as plant throughput is concerned. The refineries do have several critical units, one such unit is Hydrocracker Unit (HCU), which is used in petroleum refineries to produce mainly diesel and other middle distillates. Maintenance of specified temperature of these products is a real challenge as far as the safety is concerned. During high throughput, the cooler used for cooling the outgoing products like diesel becomes ineffective, which results in increased diesel temperature, leading to unsafe condition and reduced performance. The critical parts of the cooler will further worsen the situation. The case study presents the excerpts of process safety and performance improvement of a HCU cooling system by installing an additional cooler as an active redundancy to reduce the diesel outlet temperature. An effective risk assessment method, FMEA (Failure Mode and Effects Analysis) has been carried out to identify the critical units of the cooler unit.
