RE: Sox emissions from graphite manufacturing
Is the sulfur contained in the feed to the furnace or is it in the fuel
? If it's the fuel, then switching to natural gas or an electric
furnace would eliminate the SOx. If its your feed material, then you
can either purchase a cleaner feed material, pretreat the feed to reduce
sulfur, or scrub out the SOx after firing. All of these options depend
on many site specifics.
We typically perform an engineering study to first identify as many
options as possible for a given problem. We next identify the fatal
flaws which allows us to focus on a few viable options. After costing
out these options, you can determine the $/ton effectiveness. We also
perform a weighted sums rating of technical and regulatory merit which
defines a $/unit of performance value. This allows one to account for
intangibles in the economic assessment.
Such a study can range from $20K to $100K or more depending on the
complexity of the problem. The installed system cost can range from
$100K to several millions. For a small facility with limited budget,
they often can afford no more than a quick and cheap fix.
Unfortunately, such a thing seldom exists.
