Air Preheater Delivery Info Inquiry (采购产品): Air Preheater Delivery Info We have a client who is looking at developing a project to add the following facilities to a unit at one of their refineries: 1. Selective catalytic reduction system for NOx control including reagent storage and metering facilities, 2. Combustion air preheater, 3. Combustion air fans (one operating and one spare), and 4. Induced draft fans (one operating and one spare). Our client would need to develop a project to purchase and install these facilities during or before a scheduled unit turnaround in 4Q2008. At this point in time we need to determine if the T/A timing can be met. Specifically we are in need of data to develop a critical path schedule for such a project. To this end, we would appreciate obtaining some idea of how long delivery would be for the equipment listed above and specified in the attached pages. The information you send to us and your direct contact information will be provided to our client. As you can no doubt gather from this request (coming as late as it is) timing is critical. Your assistance is greatly appreciated. If you have any questions please feel free to contact me. Best regards, James P.
