  • (PDF) CAPTURE AND RECYCLE FOR EMISSION REDUCTION OF SULFUR

    In air separation applications, nitrogen is the “slow,” non-permeable gas and oxygen is the “fast,” permeable gas. However, for the SF6 capture application, both nitrogen and oxygen (i.e., air) are fast-permeating species. This is due to the fact that both nitrogen and oxygen have a much smaller kinetic diameter than SF6 (Table 2).

    Well Planned. If you want to have a chance of making a success of the piece of work then you need to get the basics right and in projects that means planning well. A Strong Team. Even the best project manager in the world isn’t likely to be able to deliver completed projects on time without the support of a strong team. Clear Communication. One of the features of a well run project is that it involves clear communication all the way through it. Obviously this doesn’t just depend on the project manager but when you work in this role it is something which you will want to focus on. Good Change Control. Projects change as they go on, and the things you end up delivering could be very different from what you started out looking at. This means that a robust change control process is vital.
