工业气体中H_2S的脱除方法——发展现状与展望

Ｈ２Ｓ在天然气、焦炉煤气和半水煤气等工业气体中是一种有害杂质，它不仅对输运管路、设备等造成腐蚀，影响后续加工过程（如导致催化剂中毒），而且更严重地威胁人身安全，属必须控制的环境污染源之一。迄今为止的脱硫工艺包括干法和湿法两大类，干法工艺通常适用于低含硫气体处理，大部分干法工艺所用脱硫剂均不能再生；相比之下，湿法工艺脱硫负荷高。湿法工艺包括吸收法和湿式氧化法，尽管以醇胺吸收为代表的化学吸收法早已在工业中得到应用，但吸收法实质上只是对气体中的Ｈ２Ｓ进行提浓，尚需作进一步处理，而且该法工艺本身还存在腐蚀、溶液降解及发泡等操作困难；湿式氧化法脱硫效率高，可将Ｈ２Ｓ一步转化为单质硫，是当前脱硫工艺的发展前沿。从目前看，铁基工艺较有发展前途，但寻找廉价、高效、易再生、组成简单、稳定性好的新型脱硫剂仍然是湿式氧化法发展的突出热点。

产业、空间与交通一体化的临空经济区发展规划技术体系

随着经济全球化的发展,临空经济区开始成为世界经济发展的重要组成部分。临空经济区的形成是航空经济在产业、空间、交通三要素协同演化下的结果,同时也是政府出于刺激经济发展目的下主动规划的产物。因此,从产业、空间、交通三要素协同的角度对临空经济区进行规划是新型城镇化背景下激发其作为城市经济增长极的重要途径。研究从分析产业、空间、交通三要素的基本关系入手,提出了基于三要素协同发展的临空经济区发展规划技术体系,并分别对产业、空间、交通体系中的核心技术方法进行了探讨。     

Safety Considerations during Different Stages of a Project Life Cycle in the Manufacturing Industry

At sites with multiple employers, efficient safety management is essential to ensure safety for both customers and providers. However, implementing effective safety management is challenging, particularly for companies that provide services. Provider companies encounter difficulties managing the safety of service projects for many reasons, including the variety of customers and changes in work environment. Proper preparation and integration of safety into the different project life cycle stages improves safety, but the topic has not received much attention to date. This article discusses the integration of safety considerations into service projects. Material was collected from Finnish manufacturing companies via interviews and a questionnaire. The results show that systematic methods for developing and producing services have not been adopted in the provider companies, but these are often implemented as a result of practical experience. On the other hand, providers and customers both believed that safety is taken into account during different stages of a given service project—safety issues were to some extent taken into account during the tendering and contract stages of a project, and preventive safety measures were commonly implemented during the delivery of services. However, safety performance often was not evaluated after completion of work. For this reason, companies may not have an accurate estimation of each other's safety performance in these types of multi‐employer situations. The results of this study can be used in provider organizations to help systematize safety considerations during service projects and to focus efforts on the most essential points of service project safety management.

神经网络在工业污水处理建模中的应用

研究工业污水指标在线准确检测问题,工业污水处理是一种复杂的动态生物反应工程系统,具有多变量、非线性等特点,难以建立精确的数学模型,且在线实时检测仪表价格昂贵。从应用工程角度出发,提出将遗传神经网络方法应用于污水指标实时检测,建立污水指标软测量模型。利用一些可测指标与水质指标间的关联关系,通过神经网络进行拟合,并采用遗传算法优化神经网络参数。仿真结果表明,建立的神经网络污水估计模型,可以对污水指标进行实时检测和估计,并为污水在线实时检测提供了新的思路。
