TECHNOLOGY AND PRODUCTS

Heavy oil scale chemical cleaning technology

Heavy oil scale chemical cleaning technology

Introduction The surfaces of the trays, heat exchangers, tanks and pipelines of oil refineries and chemical plants will accumulate a large amount of heavy oil scales during operation due to various reasons. These oil scales are highly carbonized and difficult to remove. The heavy oil stain cleaner developed by our company can effectively remove it after chemical transformation by using special cleaning technology and cleaning process. This technology does not require dismantling equipment and mechanical descaling, which can greatly reduce the difficulty of inspection and speed up the inspection progress.

Chemical cleaning of flue gas side of waste heat boiler

Chemical cleaning of flue gas side of waste heat boiler

Introduction Ash accumulation and fouling on the flue gas side of the waste heat boiler (economizer, outside of the water-cooled wall, etc.) is one of the main reasons for the decline in boiler thermal efficiency. Or carbonization, the removal method is more difficult than removing scale. Our company adopts spray cleaning, and then uses a unique cleaning formula, which can effectively descale and the fuel gas consumption can be significantly reduced after cleaning.

Basic sludge drying technology

Basic sludge drying technology

Basic sludge drying technology The exothermic reaction between lime and part of the free water in the sludge will increase the temperature of the sludge, which will cause the other water in the sludge to evaporate. The moisture content of the sludge can be reduced from about 85% to less than 35%. The dual effect of chemistry and chemistry achieves the purpose of sludge reduction and stabilization.
