Diesel cryogenic fluid improver XY-1

Inhibitor in Compressor XY-1

1. Introduction:

The auxiliary is a highly effective inhibitor in anti-oxidation and works well in reducing、preventing and removing the free radicals and polymers from chain growth formed by unsaturated aromatic hydrocarbons generated in the presence of oxygen, light, heat, and metallic ions, so that polymers are dispersed in the medium and flown away without blocking of system, at the same time it makes the metal passivated.

The additive is mainly used in preventing compressor set and related systems of ethylene plant from inhibition, which extends the operational life of the compressor and ensures the normal production of ethylene plant.

3、Applications,Storage and Package

1) The general injection dosage is 2μg / g ~ 10μg / g and up to the feed rate of the compressor. It is suggested to inject 10μg / g separately in the first 7 days in each stage, in order to make the active ingredient in the additive form a protection film on the surface of the cylinders and pistons and have the metal passivated. Then, the injection dosages in the first stage, the second stage and the third stage drop to 8μg / g, and the dosages of the fourth stage and the fifth stage drop to 4μg / g, all of which are injected evenly and continuously. In order to make the additive injected to each stage of compressor together with washing oil and realize the effect of inhibition for the whole compressing system, the inlet of washing oil pump of cracked gas compressor should be selected as the injection point. The additive can be injected by metering pump evenly and continuously, or diluted with gasoline to a certain concentration based on actual demand.

2) Storage: This additive is of non-toxic alkaline and flammable. 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 kg/drum net.
