【摘要】：随着M油田进入开发后期,天然气产能大幅递减,由于产能规模扩大、开发难度增加、高酸性气净化能耗上升等因素,造成天然气净化厂能耗持续上升,为了将总能耗和单位能耗增长控制在合理的范围内,本文对天然气净化厂的能耗进行了全面研究,以便建立一种通用的能耗评价方法,为天然气净化厂制定节能降耗措施进行指导。本文首先对天然气净化厂的能耗现状进行了调查,通过分析天然气净化过程中的能源消耗状况,确定了天然气净化厂的主要耗能部位,其中电能消耗的主要部位包括甘醇循环泵、MDEA循环泵、循环水泵、空气压缩机、空冷电机、水泵等,其它能源消耗部位主要包括甘醇再生器燃料气消耗、蒸汽锅炉燃气消耗、MDEA再生器蒸汽消耗、硫磺回收装置加热蒸汽消耗及公用工程的能源消耗。在此基础上,我们确定了天然气净化厂的能源能源绩效参数(EnPI)和评价指标,然后将能源绩效参数(EnPI)和评价指标进行回归分析,建立了天然气净化工艺的数学模型,通过监测与分析能源消耗数据,对天然气净化厂以及单元装置、设备进行能耗评价,最后根据评价结果制订节能降耗方案,提出设备改进和工艺操作优化的建议。同时,本文通过上述工作建立了一种新的针对天然气净化厂的能耗评价方法体系,这种技术可推广到各个天然气净化厂,从而为每一个净化厂制订符合自身需要的能源管理方法。
[Abstract]:As M oilfield enters the late stage of development, the natural gas production capacity decreases dramatically. Due to the expansion of production capacity, the increase of development difficulty and the increase of energy consumption of high acid gas purification, the energy consumption of natural gas purification plant continues to rise. In order to control the increase of total energy consumption and unit energy consumption within a reasonable range, the energy consumption of natural gas purification plant is studied comprehensively in this paper, in order to establish a general energy consumption evaluation method. In this paper, the present situation of energy consumption in natural gas purification plant is investigated, and the energy consumption in the process of natural gas purification is analyzed. The main parts of energy consumption in natural gas purification plant are determined. The main parts of power consumption include MDEA circulating pump, circulating water pump, air compressor, air-cooled motor, water pump, etc. Other parts of energy consumption mainly include fuel gas consumption of glycol regenerator, gas consumption of steam boiler, steam consumption of MDEA regenerator, heating steam consumption of sulfur recovery unit and energy consumption of public works. The energy performance parameter (EnPI) and the evaluation index of natural gas purification plant are determined, and then the regression analysis of energy performance parameter (EnPI) and evaluation index is carried out, and the mathematical model of natural gas purification process is established. Through monitoring and analyzing the data of energy consumption, the energy consumption of natural gas purification plant, unit unit and equipment is evaluated. Finally, according to the result of evaluation, the energy saving and consumption reduction scheme is formulated, and the suggestions of equipment improvement and process operation optimization are put forward, at the same time, Through the above work, a new energy consumption evaluation method system for natural gas purification plants is established, which can be extended to each natural gas purification plant, so as to formulate energy management methods for each purification plant in accordance with its own needs.
