蒙西地区储能技术经济性优化配置研究

蒙西地区近年来可再生能源装机容量占比逐年提高,亟须配置大规模储能降低其间歇性、波动性给电力系统带来的影响。为实现蒙西地区储能的最优化配置,设计提出蒙西地区储能技术经济性优化配置模型。首先,兼顾技术性和经济性对蒙西地区储能的选址、选型开展研究。其次,以平抑风光出力波动性最大化和包含外部价值在内的储能项目收益最大化为目标,构建储能技术经济性优化配置模型,并采用NSGA-II算法对该模型进行求解。对蒙西某风光聚集地区的实证研究表明：当风光出力波动抑制率控制在30%以内,且光伏占风机的装机比例较低时,配置一定规模的储能可在技术、经济2个方面收到显著成效。最后,基于选址选型和实证分析结果,给出蒙西地区的储能配置方案。

敏感价格区间内中间基减压蜡油加工方案对比

在50~100 USD/bbl(1 bbl≈0.133 t,以布伦特原油为基准)的国际原油价格下,对中间基沙特轻质原油 沙特重质原油(沙轻-沙重)的混合原油减压蜡油的不同加工方案进行了模拟研究,考察了流化催化裂化(FCC)、催化裂解(TMP)、催化柴油加氢-催化裂解(加氢 催化裂解,HTMP)和加氢裂化(HCR)对CO2排放、柴/汽比、基本化工原料和高价值产品收率等技术指标的影响,并进行了经济效益对比分析。结果表明：当原油价格处于中低价位(＜80 USD/bbl)时,采用产物分布中丙烯和高辛烷值汽油的收率之和高达60%的加氢-催化裂解方案可以降低柴/汽比,实现最短的资金回收周期;对于炼化一体化项目,采用加氢裂化方案可以获得最高的基本化工原料和高价值产品收率,当原油价格在中高价格(＞80 USD/bbl)范围内,采用HCR方案可以提高装置的经济效益和抗油价波动能力。

On the Economics of 3G Mobile Virtual Network Operators (MVNOs)

The paper assesses the market conditions and dynamics, the architectures and the different approaches for deployment of 3G Mobile Virtual Network Operators (MVNOs), in an attempt to address specific advantages and pitfalls. Following the definition of appropriate service sets and tariff structures, and taking into account demand scenarios, a techno-economic model has been developed, in order to compute key economic indicators. The paper presents techno-economic results of specific business cases and deployment alternatives for an average “large” European country and a smaller, Nordic-type country. Fixed and variable costs have been identified and the business case shows how different service sets lead to different costs. Different MVNO business profiles have been investigated. Profitability for all scenarios and business profiles has been calculated, presented and discussed. Major opportunities and threats, as well as critical parameters and uncertainties have been identified through sensitivity analysis.

羟醛缩合法制甲基丙烯酸甲酯催化剂研究及技术经济性分析

制备了Cs/SiO₂催化剂,在固定床反应器中研究了其催化甲醛与丙酸甲酯羟醛缩合反应性能,并采用X射线衍射、场发射扫描电镜、X射线荧光光谱分析和热分析等手段,对催化剂组成和结构变化跟踪分析。采用80%的浓缩甲醛为甲醛源,单程1000h反应过程中,丙酸甲酯转化率13%~15%,甲醛转化率60%~65%,丙酸甲酯为基准的甲基丙烯酸甲酯（MMA）选择性93%~95%。长周期反应后,催化剂晶型结构和形貌未发生显著变化,活性组分Cs未出现明显聚集和流失,积炭量有所增加。原位烧碳再生后,催化剂活性得到恢复,初始活性高于新鲜催化剂,随着反应的进行,甲醛、丙酸甲酯转化率等指标逐渐趋稳,接近再生前的平均水平。在近1700h的反应时长内,丙酸甲酯为基准的MMA选择性93%~95%,催化剂总体稳定性较好。技术经济分析表明,以羟醛缩合为核心技术的煤基MMA合成新路线,较传统的丙酮氰醇法和异丁烯氧化法MMA技术安全环保、经济高效,契合我国富煤、贫油、少气的资源结构和国家煤化工产业升级鼓励政策,可突破C2和C4路线商业技术的专利封锁,改变MMA行业现有技术格局,为煤化工企业进军MMA合成技术领域提供重要途径,同时可消化国内乙酸、甲醛的过剩产能以及大量低值化利用的副产乙酸甲酯,丰富我国煤化工产品链。
