Diesel cryogenic fluid improver XY-1

Scale inhibitor for hydrogenation cracking XY-1

1、Introduction

The product is a multi-functional composite additive based on the mechanism of scaling formation in hydrocracking of crude oil , with the small amount of product being put in up-stream of converter or reactor before crude oil being fed in, so as to refrain the heat exchanger or reactor from scaling formation, even to eliminate some of the established scales. Therefore, it can significantly reduce the plant power consumption, by extending the operating cycle and reduce maintenance costs. Moreover, it has no harmful effect on follow-up hydrogenation catalyst and product distribution. The product also shows a good performance of oil solubility, moderate viscosity and easy application, etc.

3、Applications,Storage and Package

1) The product is mostly applied in antifouling of hydrogenation feed oil/heat exchanger, it should be injected upstream of  heat exchangers before the feedstock entering, it will be better to inject the product into pipe which needs pre-cleaning. The injection dose is up to performance of feedstock oil, normally at 50—100ppm, the initial dose should be 100ppm, which can gradually drop to 50ppm.

2) It should be kept away from sunlight, heating source, moisture, impurities, and away from spark.

3) 175kg net /Galvanized iron barrel
