An improved algorithm for process topology analysis has been proposed and programmed in ALGOL 60. By means of a comparative study, the author decided to use reachability matrix technique for identification. A considerable savings in storage and computation, time realized. Two heuristic methods have also been suggested to select the best cut streams: (1) to minimize the weighting factors; (2) to avoid the "double tearing". The methods presented in this paper are quite efficient and very easily programmed. Up... 对化工流程的拓扑分析,提出了一种改进算法,并用ALGOL 60语言编写了程序。在识别部份,作者通过对比研究选用可达矩阵技术,使存贮量和计算时间都有显著压缩。在最佳切流的选择上,提出了两种启发式方法:一种以最小权重因子作判据,一种用于避免“二次切断”。方法的特点是简单有效,很容易编写程序,可分解结点数达700个的大系统,程序本身可用作为化工模拟系统的拓扑分析模块。 文摘来源 Eecently intense vibration of some compressors have occured in thirteen imported large fertilizer plants and several home-made chemical plants, that affects the normal operation seriously. By a number of tests, this paper presents that the running speeds of such compressor rotor is considerably high and near the second critical speed, the mixed vibration of second and third mode will thus be generated. The conventional stage by stage low speed balancing method is useless in such cases. These rotors must be ... 近年来国内引进的十三套大型化肥设备及某些国产大型化工流程中的压气机.有不少型号发生了强烈的机组振动,以致严重地影响了正常生产.作者通过大量的试验实践,认为这些高速压气机转子工作转速都很高,位于第二临界转速左右,转子在工作转速范围内将发生二三阶的混合振型的振动,传统的逐级低速平衡法已无效用,必须进行高速动平衡.实践证明,这种转子经高速平衡后能够在全转速范围内达到平稳地运转. 文摘来源 Our HP-1000 computer is a small computer only with 128 KW memory. But we have successfully run a large petro-chemical program on it. The program with the name as SIMU is very flexible. With SIMU we can simulate many complex petro chemical processes. The computation method of distillation towers presented in the paper is a new one which can be used to compute all petro-chemical distillation towers with a very small memory. The solutions are reliable. The computation method of gas-liquid equilibrium K values ... 经过近两年的努力,在内存只有128KW(256KB)的小型计算机HP-1000上建立起了大型的炼油化工流程模拟程序。该程序综合了国内外流程模拟程序的优点,结构灵活,能够模拟以分馏为中心的各种复杂的炼油化工过程,程序对分馏塔的数值计算方法作了重要的改进,能在内存需要量很小的情况下,得到严格的可靠的数值解。在平衡常数和汽液相热焓的计算中,采取了一系列的检验和保证措施,提高了求解的可靠性。由于程序具有上述特点,因而使它成为炼油工艺设计中的强有力的工具。 文摘来源 << 更多相关文摘
