Development and Evaluation of Nanoscale Sorbents for Mercury Capture from Warm Fuel Gas. Shakedown Testing of the Experimental System (Task 1). Topical Report 1. (Revised);Rept. for 27 Sep 04-30 Nov 04

摘要

The Mercury Testing Experimental System available in GTI's Hot Gas Cleanup laboratory was prepared for the project. As part of the shakedown testing, the system was checked for possible gas leaks and fixed. In addition, the mass flow controller was calibrated for diluent N2 stream. A major part of the shakedown testing was the calibration of the semi-continuous mercury analyzer and the verification of the permeation rate of the mercury permeation tube. It was found that the analyzer's mercury concentration measurements were much lower than expected from the permeation tube rate calculations. Vendors of the analyzer and the permeation tube are contacted to find out the reason for this discrepancy.
