Chemtura can supply bromine as calcium bromide or in many other forms. The company works with clients from inception through continuing operational support. Setting up calcium bromide systems is relatively easy but there is no reason to over-design and invest more than necessary or to under-design and create operational problems. Chemtura is conducting tests which show the impact of bromine in the gas and scrubbing liquor on the materials with which it may come in contact. The quantity of bromine added can vary to compensate for changes in the process e.g., changes in fuels or deterioration of the catalyst. Since activated carbon is quite expensive it makes sense to utilize bromine with the fuel to supplement the carbon under upset conditions.

Corrosion Studies on GeoBrom® HG520 Partial Immersion Study
Brominated derivative products for mercury control… There was little to no corrosion observed on these coupons in the vapor space. Visually, all corrosion occurred in the liquid phase where half of the coupons were suspended. There was no increase in corrosion rate observed at vapor / liquid interface on any of the specimens. Based on this 90 day study, all specimens were less than 0.70 mpy corrosion rate with half the coupon below surface. Mild carbon steel (C-1018) gave the highest corrosion rate at 0.14 mpy at 20° C and 0.65 mpy at 50° C. All remaining specimens were under 0.10 mpy. ICP analysis of GeoBrom® HG520 samples refl ect elevated iron and chromium levels at end of the 90-day period. The maximum allowable corrosion rate for each specimen with GeoBrom® HG520 depends on the application.

Corrosion Studies on GeoBrom® HG520 Total Immersion Study
A 90-day, total-immersion corrosion rate study was conducted using GeoBrom® HG520 calcium bromide solution and six selected metals at 20° and 50° C. ASTM Method “Standard Practice for Preparing, Cleaning, and Evaluating Corrosion Test Specimens” G1 - 03 (reapproved 2011) was used to prepare, clean, and evaluate tests specimens.
