Problem 1
A large scale chemical processing site requires large quantities of heat (at
temperatures ranging from 600°C to 100°C) and power. Carbon based fuels are
used in a variety of devices, such as fired heaters, steam boilers, and gas turbines.
These devices, some coupled with steam turbines, produce the required heating and
power for the site. The site can also import and export power.
It is required to reduce carbon based emissions from the site. The reduction
methodologies can include efficiency measures, integration of “greener” fuels, and
more widely based integration with “over the fence” sources and sinks of heat and
power.
What suggestions can you make for measures to reduce these carbon based
emissions, and what are the limitations on adopting these measures?
