Control of Volatile Organic Compounds Emissions from Manufacturing

I
~ Inserting the above information into the general cost-effective equation
(I), the foll owing equation is derived:
For a si ngl e process 1 ine :
(5) CE = $8,300 - C36.75 ER - 4.411 (0.9) [$788/kg]
, .
For two process lines:
(36.75 ER - 4.41)
(6) CE = $8,300 - C73.5 ER - 8.821 (0.9) [$788/kg]
(73.5 ER - 8.82)
As we know CE (i .e., $1,00O/Mg; $2,00O/Mg; or $3,00O/Mg), we can
solve directly for ER. Simplifying the above equations (5 and 6), we
get :
I
For a single process 1 ine:
(7) ER = 11,428 + 4.41 CE
26,063 + 36.75 CE
For two process 1 ines (i ,e., the model plant) :
(8)
ER = 14,555 + 8-82 CE
52,126 + 73.5 CE
Substituting $1,00O/Mg, $2,00O/Mg, and $3,00O/Mg into the 1 ast two
equations (7 and 8) , yields the following results:
Emission Rate, kg VOC/M~ Product
Single Line Two Line
$1,00o/Mg 0.2521 0.1861
$2,00O/Mg 0.2034 0.1617
$3,00O/Mg 0.1809 0.1504
F.2.2 Styrene-in-Air Emissions
As with styrene-in-steam emissions, the basic equation for calculating
cost effectiveness is as follows:
