化工项目试车工作流程.ppt

* * 热试车期间的指挥调度和监督Coordination and Supervision during Hot-commissioning 此阶段在装置现场实地的双重监督是必不可少的 Additional personnels, both supervisory and “on the-ground” are required at this stage; 试车管理人员和业主装置管理人员间的合作是至关重要的 Cooperation between commissioning personnel and plant supervisory personnel is critical at this stage: 每天至少一次的例会制度 Need a daily meeting at least; 经常性的班前、班后会 Often, a briefing each shift. 故障诊断Trouble Shooting 在此阶段 ，许多设备问题将显现出来 At this stage, many problem with equipment of the process itself may become apparent; 试车过程一般都会经历一个高频的（希望是短暂） 所谓“故障诊断、解决方案、工程修改和装置改造的过程” The commissioning process goes through what is often an intense (and hopefully short) period of problem trouble shooting, problem solving, engineering correction and plant modification; 试车过程的保运 确定保运队伍(视合同) 编制并发布工作程序及安全规程 明确试车期间的保运任务范围 准备保运所需的备品备件及消耗材料 建立保运记录档案 做好日常巡回检查维护 编制并实施停车检修计划 性能考核及验收 作业流程 第六部分 性能考核及验收Performance Test Acceptance 性能考核 Performance test; 正式验收 Formal acceptance 策划及准备 Preparation and Planning 机械竣工及预试车 Mechanical Completion Pre-commissioning 冷试车 Cold-commissioning 性能考核及验收 Performance Test Acceptance 热试车 Hot-commissioning 试车后活动 Post Commissioning 性能考核的先决条件Before the performance test need to ensure that… 装置的运行状况即温度、压力、液位及分析数据已相对稳定；若为间歇工艺，则重复性已较好 Control of plant operating conditions has been achieved. I.e. temperature, pressures, levels and analyses are reasonably constant or in the case of a batch process, there is repeatability; 每天的物料及能量已达到平衡并于正式的生产数据相一致 Daily material and energy balanced can be performed and that these agree with “official” production figures; 产品性能质量稳定 Product specifications are being achieved consistently. 性能考核The Performance Test 一旦装置可全负荷运行，即应组织实施性能考核以证实装置应达到的性能 Once the plant is fully operational, the final “proving trail” or performance test is performed in order to prove the plant can do what it is supposed to do; 装置所运行必需的每一独立变量的范围或量值——流量、温度、压力及浓度等等逐一设定 The values or range of values for each independent variable - flow, temperature, pressure, level, concentra
