Trapped radiation circulating

For the MP header, steam input comes from the process-fired heater F-5001 where the radiation section is used for process feed heating, while the convection section for MP steam generation. MP steam is also made from the extraction of CT-1401 turbine, the HP letdown, and two WHBs. On the other hand, MP steam is used as column reboiling and stripping as well as in the steam turbines and MP letdown. CT-1601 turbines run a compressor and boiler PTs include four small turbines used for running a boiler water circulation pump and three AD fans. Since MP letdown is not measured, it is unknown and to be determined together with the MP imbalance. The MP imbalance includes metering error, steam losses due to steam traps, leaks, and so on. Table 16.10 shows the balance for the MP header. 

Brian Flannery I m willing to make a very quick stab at your question. I think everyone is convinced that the buildup of greenhouse gases traps extra infrared radiation in the atmosphere, and this could lead to a problem down the road. There are few people who aren t convinced, at least in terms of the radiative transfer issues. The deep scientific questions in climate change concern the feedbacks that may occur, and the future of forcing from human actions. Once heat is trapped, climate processes, such as clouds, ocean circulation, hydrology and moist convection can change in ways that science cannot yet predict.
