摘要

ADNOC天然气处理在其能源卓越之旅中,采用了一种新颖的内部方法来进行能源绩效基准测试。该方法主要侧重于单位和设备级别的性能比较,以确定差距并根据最佳国际惯例突出改进机会。基准测试是通过将任何方面与不同级别和尺度的标准或任何其他参考进行比较来评估任何方面。在石油和天然气工业中,辅助锅炉通常主要消耗天然气产生蒸汽用于过程加热。由于多种原因,锅炉的能源性能容易下降,导致效率降低。由于辅助锅炉的能源性能在燃气处理的整体能源效率中具有重要意义,ADNOC燃气处理公司对安装在其多个站点的辅助锅炉进行了内部能源性能基准测试。对共25台辅助锅炉的能源性能进行了不同指标的分析和评价,以检查其目前的性能,并与其他锅炉进行基准测试,以寻找可能的改进。基准测试还评估了整个蒸汽和冷凝水系统。在流程优化、最佳实践和基于资本支出的能源效率倡议方面,我们发现了改进的机会。基准测试工作揭示了在烟气过量氧优化、补充水管理、减压站能源回收、废热回收和蒸汽疏水阀审计等方面的节能机会。研究还强调了绩效监测方面的改进领域,包括计量、持续优化和持续改进。

Auxiliary Boilers Energy Performance Benchmarking
ADNOC Gas Processing, in its journey towards energy excellence, has adopted a novel in-house methodology for energy performance benchmarking. This methodology is primarily focused to unit & equipment level performance comparison, to identify gaps and highlight opportunities for improvement following the best international practices. Benchmarking is an evaluation of any aspect by comparing it with a standard or any other reference at different levels and scales. Generally, in an Oil & Gas Industry, auxiliary boilers mainly consume natural gas to produce steam for process heating. Energy performance of boilers is susceptible to decline due to several reasons and results in reduced efficiency. Owing to the significance of auxiliary boilers energy performance in the overall energy efficiency of gas processing, ADNOC Gas Processing conducted an in-house energy performance benchmarking of auxiliary boilers installed at its multiple sites. Energy performance of total twenty five (25) auxiliary boilers was analyzed and evaluated in terms of different indices, to examine their current performance and benchmark it with other boilers for potential improvements. Benchmarking also assessed overall steam and condensate systems. Opportunities for improvement were observed in areas of process optimization, best practices and CAPEX based energy efficiency initiatives. Benchmarking exercise revealed energy savings opportunities in flue gases excess oxygen optimization, make-up water management, energy recovery from pressure letdown stations, waste heat recovery and steam traps audits. Study also highlighted areas of improvement in performance monitoring encompassing metering, sustained optimization and continual improvement.
