CASE STUDIES FOR TEXTILE PRINTING
CASE NO. 8
Description: RJR Archer, Inc. is a paper printing
operation. The company was having a great deal of
problems with air emissions from its printing presses.
Courses of Action:
RJR Archer installed a carbon adsorption system to
capture and recover 98% of the solvents lost to the
atmosphere from drying ovens. This amounted to an average
of 2,655 gallons per day. This solvent could be either
reused or sold. By properly recirculating air exhaust from
its drying ovens before distillation, the size of the
system was smaller than originally predicted.
Additionally, all inks formulations were reviewed and
reformulated using a maximum of two solvents per blend,
therefore increasing the recovery system efficiency.
Savings:
RJR Archer saves over $6,300 per day in solvent costs.
The payback for the $4.3 million recovery system was 2.5
years. After payback, RJR Archers estimated an annual
$1.7 million net cost savings.
Air emissions are also very important to a number of
textile printers.
