With new national standards for emissions in China, our refinery client was desperately searching for a way to bring their operations up to scratch. Their previous packing solution could let out more than 8000PPM leakage and it was their goal to reduce this down to below 100PPM. With the help of the Chesterton team and the Chesterton® Low E Packing 1622, they were able to sufficiently reduce their emissions by close to 40 times at a new 50PPM after several months of operation.
