崩溃一篇三百多字的作文

Good afternoon, everyone! It’s my pleasure to share some of my idea on energy optimization with you here! 2 First, as the graphs show, we can form the composite curves with HCC and CCC. 3 Next, we can put the Pinch near where the minimum ΔT is. 4 Then, we have the equation and rules for the Pinch. 5 To match the streams, we also need these four principles. 6 But it’s not completely finished yet, so we need to apply the driving force plot, which includes three steps. 7 Now we’re moving on to the Grand Composite Curve, GCC. First, we need a CC, and shift the curves to get an SCC. Then plot the horizontal distance to form GCC. 8 Sometimes, there can be pockets in GCC and a lot of high pressure steam will be wasted. We can add medium pressure steam, which can be heated for warming. 9 Sometimes, the heat recovery isn’t so good. Then we can increase the column pressure to raise the condenser curve. And there will be a step change, which means the utility will decrease a lot. 10 But this method isn’t perfect, because it will increase the capital cost. 11 And we also have Plus/Minus Principle. It is also a good way to save energy. 提问处 12 Here, for example, the harder refrigeration is decreased. 13 In this condition, the reboiler and condenser cross the Pinch. We can increase the pressure to raise them in the GCC. The Q will decrease, and the column can run for free! 13 2 And this is an example. 总结 In general, the GCC is just a good tool for chemical engineering processes, instead of principle. In actual production, we need to consider the problems synthetically. 提问 I’d be keen to hear how you think about this method and to hear any of your concerns or questions. 提问： In the Plus/Minus Principle, what measures can you take to achieve the goal to save energy?In the first example, we can lower the pressure to decrease the use of HP. In the second, we can increase the pressure. 世界杯许愿 贴吧世界杯球队排行榜名次乱入贴吧助攻值138222002309945032992950名次球队助攻值登录帐号我的游戏推荐游戏 后查看最近玩过的游戏 吧友热玩游戏排行 1回复贴，共1页
