Tier 3 gasoline standards are looming on the horizon. By 2017 refiners will be required to reduce sulfur in gasoline from the tier 2 level of 30ppm to an average of 10ppm.
The EPA anticipates refiners will need to make "minimal" changes to operations in order to meet the new standard; refiners beg to differ. Refiners anticipate they'll need to expand hydrotreating processes (especially in naptha produced in fluidized catalytic cracking (FCC) units). Refiners expect to shell out up to $10 billion in upgrades and an additional $2.1 billion per year in operating costs; overall project duration of 2+ years is expected. So now's the time to begin Tier 3 planning.
SilcoTek® coatings are a major asset in achieving Tier 3 refinery compliance. Inert coatings like SilcoNert® 2000 and Dursan® coat the entire sample pathway to assure an inert flowpath.
Ultimate inertness
SilcoNert® 2000 prevents adosrption of H2S and other compounds in sample cylinders, tubing and other sampling surfaces. In fact SilcoNert is so effective in preventing H2S loss that samples can be stored for 14 days or longer without loss of sample integrity. Without SilcoNert, the sample would be completely adsorbed into the stainless steel sample cylinder within hours.
Incomparable response
The old adage, do you want it right or do you want it now has been turned on it's head. SilcoTek coatings allow operators to get the sample right and now!
The Old Sulfur Management Ways Won't Cut It.
Hoping to avoid coating the entire sample flowpath? Prepare for major headaches. The sampling methods used for 30 to 50ppm sensitivity most likely will not produce meaningful sample results. Here are a few that won't cut it:
Why take the risk? SilcoNert® 2000 and Dursan® are proven to improve sensitivity and response. Coating the entire sampling flowpath will assure compliance and allow operators to focus on operations, not troubleshooting an unreliable sampling system.
