SPS是一个功能强大的软件,使用它可以对液体、气体管道的水力和热力特性进行精确的模拟分析和预测。它适用于单一流体、批次输送流体以及单相混合流体,但不适用于多相流。按照SPS说明书的描述,它有以下功能:
•Analyzing startup and shutdown procedures •启停步骤分析 •Analyzing operational stability •稳态分析 •Analyzing pump/compressor operating schedules •泵/压缩机操作过程分析 •Studying economics of various designs and operational strategies •多方案设计经济性研究 •Designing sequencing systems •程序化系统设计 •Designing surge relief systems •水击泄放系统设计 •Designing cascade control systems •连锁控制系统设计 •Studying survival time for gas delivery systems •气体泄放系统的自救时间 •Analyzing system response to potential upset conditions and evaluating corrective strategies •分析系统对潜在故障工况的响应并评估修正方案 • P redicting environmental impact of potential pipeline leakage •预测管线泄漏对环境的影响 •Studying the effects of batching, side stream delivery or supply blending •进行批次分析及分输/输入混油分析 •Studying temperature rise in re-circulation systems and cooling or heating of products due to a transient interchange of heat with the pipeline surroundings •研究再循环系统温升及管线与环境的瞬时热交换而发生的制冷/制热 •Studying thermal effects in gases, especially non ideal gases, such as Joule-Thompson cooling, decompression cooling, and inter-stage cooling required with polytropic compressors •研究气体,尤其是实际气体的热效应,例如焦耳-汤普生冷却、压冷却、多元压缩机的级间冷却 •Designing minimum flow bypass controls to prevent surge conditions in polytropic compressors •进行流量旁通设计,预防多元压缩机的冲击情况发生 •Studying the effects of pipe rupture, blow down cooling in gas pipelines to assess pipe steel brittleness, effect of pipe wrap and thermal environment in pipe burial on blow down rate •研究管道抗裂程度,气体管道冷泄放以评估管道韧性,管道包裹层及敷设处热力环境对泄放速率的影响
