今天听说今年要出9.0版本的软件啦? aspen technology aspenone 8.8 包括: - aspen engineering 8.8 dvd - aspen manufacturing and supply chain 8.8 dvd - aspen process manual and aspen process tools 8.7 dvd aspen suite是大型通用流程模拟系统,源于美国能源部七十年代后期在麻省理工学院(mit)组织的会战,开发新型第三代流程模拟软件。该项目称为“过程工程的先进系统”(advanced system for process engineering,简称aspen),并于1981年底完成。1982年为了将其商品化,成立了aspentech公司,并称之为aspen suite。该软件经过20多年来不断地改进、扩充和提高,已先后推出了十多个版本,成为举世公认的标准大型流程模拟软件,应用案例数以百万计。全球各大化工、石化、炼油等过程工业制造企业及著名的工程公司都是aspen suite的用户。 选择同类最佳的单点产品,我们的是一套整合的aspenone解决办法: 设计优化设施更快 更有 效率地响应市场和业务的变化 实现更高的吞吐量,较低的成本 加快产品介绍和提高质量 规范关键工序,并利用现有的投资 aspen 套件 (aspen suite) 主要应用于一些关键的领域,如﹕研究和开发阶段的数学模拟放大﹑概念设计﹑工艺设计及工程设计﹑工厂开工指导及操作工仿真培训﹑工艺流程改进及优化﹑工厂脱瓶颈及技术改造﹑工作流集成。 aspentech 公司不但在供应链管理软件及服务方面是一个领先供应商(在世界化学工业的供应链软件市场佔22.5%份额),而且还能够把一个公司及其延伸企业的所有方方面面的业务,从电子商务市场直到车间操作室都集成起来,提供端到端的解决方案。 aspen technology aspenone 8.8 | 16.8 gb aspen technology, inc., a leading provider of optimization software for the process industries, announced the general availability of aspenone engineering and aspenone manufacturing and supply chain version 8.8 software. developed for firms in the oil, gas, chemicals, engineering & construction and other process industries, aspenone 8.8 is a powerful software release featuring user-friendly, streamlined workflow innovations that allow users to minimize capital costs, improve plant productivity and boost operational profitability. with this latest release, aspentech delivers the technology enhancements needed to achieve operational excellence, enabling leading global firms to improve margins, increase yields, meet customer demand, gain competitive advantage and implement innovation across the enterprise. included: - aspen engineering 8.8 dvd - aspen manufacturing and supply chain 8.8 dvd - aspen process manual and aspen process tools 8.7 dvd the aspenone v8.8 software benefits include: - capital and energy cost optimization with streamlined workflows. enhancements to activated analysis in aspen hysys® and aspen plus® improve performance and usability. fully integrated cost estimation, energy optimization, and heat exchanger design and rating (edr) technology brings key information to the process simulation environment, allowing faster and more accurate optimal design selection earlier in the conceptual engineering phase. the updated edr user interface provides easier access to advanced features of the edr product suite, aspenone exchange and the direct availability to the htfs research network. - safety improvements via increased relief sizing capabilities. new relief load calculation enhancements for heat exchanger tube rupture, fire emergency and control valve failure expand relief sizing and safety modeling capabilities. time to conduct pressure relief analysis is generally reduced by 50 percent. - lower operating costs due to accurate methanol partitioning modeling . with the addition of the cubic plus association (cpa) fluid property package, v8.8 software more effectively models methanol behavior to accurately predict hydrate formation, improving flow assurance in pipelines and meeting environmental regulations. - optimized throughput and planning with complete suite of reactor models . new naphtha hydrotreater and alkylation models create a complete refinery reactor and assay management suite from within aspen hysys petroleum refining. for the first time, our customers have a brand new, complete suite of refinery reactor models available. the resulting flexibility means all process units can be accurately modeled and optimized, supporting planning for maximum profits. - energy savings with the extension of polymer modeling to solids . polymers can be treated as solids below their melting points in aspen plus, allowing for accurate upstream and downstream modeling of solids production, including dewatering and drying. - fast adaptation of controller strategy to economic objectives . the new smart tune technology in aspen dmc3 enables users to quickly adapt to changing economic scenarios. it lowers the barrier to controller design and maintenance by providing more insight into controller strategy, and allows more users to set up and periodically reconfigure the optimizer more frequently with reduced workflow complexity. - improved plant scheduler efficiency with advanced campaign management and visualization. the new campaign manager in aspen plant scheduler™ enables speedy creation and scheduling of an ideal production sequence or product wheel. proven sequencing algorithms further optimize grade transitions to reduce off-spec production and enhance asset utilization. what's new in 8.8: http:///products/v8-release/ about aspentech aspentech is a leading supplier of software that optimizes process manufacturing – for energy, chemicals, engineering and construction, and other industries that manufacture and produce products from a chemical process. with integrated aspenone solutions, process manufacturers can implement best practices for optimizing their engineering, manufacturing and supply chain operations. as a result, aspentech customers are better able to increase capacity, improve margins, reduce costs and become more energy efficient. name: aspen technology aspenone version: 8.8 3dvd home: http:// interface: english os: windows xp / vista / 7even / 8 / 8.1 size: 16.8 gb 查看更多

感觉 电气 专业帖子不多? 的确,电气专业的同志要加强学习。就像我们公司,是一家机电工程公司,专业提供机械、电器、仪表方面的人才服务。我是学习自动化的, 以前在别的企业干时也做过电器和仪表方面的工作,前年来这家公司时,在这两个专业里选择了仪表。主要是觉得电器专业还是像电老虎一样,太牛了。我们公司仪表专业的小伙子都爱学习些。 这里没有贬低电器专业的意思,本来电仪就不分家。大家是一家。查看更多
