gasoline analyser

[rgrokkam]

I am looking for a sulfur analyser, to be installed in a gasoline line. The analyser should work in 350ppm-10,000ppm and a response time of few seconds.
I've seen quite a few websites but I dont get the capital cost of such analysers. I need this info for a cost analysis. Can the forum help me in getting more details regarding this?

Many thanks

BP Marine fuels has been working with Spectro to develop the X-Ray fluorescence sulphur analyser to be suitable for heavy fuel oils.
I've been told this type of analyser can cost around £40,000 but I'd suggest that you really need some quotes from the manufacturers as there is, as implied from the Spectro/BP development, quite a bit of work being done which may impact on price significantly.
MARPOL Annex VI (Marine pollution treaty which regulates fuel sulphur) does not mandate online measurement of sulphur probably for the reasons reported by MARTOB (a report to the EU on Marine pollution); that they are expensive and require ongoing maintenance by skilled technicians. It is these objections that BP and Spectro have been working to overcome (for fuel suppliers, not for the vessels yet.)
I have no idea what the costs are for other technologies such as lead acetate strip etc.

The marketplace includes several manufacturers of total sulfur as well as hydrogen sulfide. These have become popular for those making ultra-low-sulfur-diesel (15 ppm) and other process applications. The example of the total sulfur already mentioned was Ametek Spectro. Other examples include Thermo Sola II, XOS Sindie, Antek P 6200, ABB, Siemens, etc.

X-Ray fluorescence is popular although additional ASTM standards exist. See ASTM
D 2622 Sulfur in Products by x-ray fluor spectrometry
D 3120 Trace sulfur in liquid petroleum microcoulometry
D 3227mercaptan potentiometric
D 3246 Sulfur petroleum gas oxidative microcoulometry
D 4294 Sulfur in petroleum X-ray Fluorescence
D 5453 Sulfur in light HC sparg ignition diesel UV fluorescence
D 5623 Sulfur in Petroleum Liquid by GC
D 6334 Sulfur gasoline x-ray fluorescence
D 6445 Sulfur gasoline x-ray fluorescence,
D 6920 Total sulfur oxidative combustion electrochemical
D 7039 XRF sulfur in gasoline,
D 7041 Total Sulfur HC GC flame photometric
D 7220 Sulfur in fuel by X-Ray Fluorescence

Order of Magnitude Cost Estimate (a bit better than a WAG)
Consider the following range for your starting point
Analyzer $60 k-80,000
Sample system $15 k-$25000
Shelter $85 k-$120,000
Engineering Charges for someone like me - 200 mh
