3、Applications,Storage and Package

1) The general dosage is 20μg / g ~ 100μg / g (based on materials).  The first 100μg / g can be added and then gradually decreased to 5μg / g after running a few days. The optimum dosage should be determined after observation. The injection point is located before feeding into knockout tower, or at the feeding side of reboiler to ensure that the additive is fully mixed with the medium when entering into the system. The additive can be infused evenly by metering pump at room temperature or in situ temperature. When necessary it can also be infused after being diluted to certain concentration.

2) Storage: This additive is inflammable and non-toxic. Prevent it from being exposed to the sun, rain and impact during transportation. Store it in a dry, cool and ventilated warehouse, away from heat and fire source.

3) Package: Steel drum with plastic lining or plastic drum, 170 ± 0.5 kilograms/drum net.
