Recently, Shanghai Petrochemical Refining Department's No.
2 atmospheric and vacuum unit with an annual output of 6 million tons used the water-based purge-free grease cleaner for the first time during the shutdown of the 250 series and 350 series, instead of the traditional shutdown purge method.
The device performs descaling, which effectively solves the problems of increased steam consumption, heavy odor on site, and large labor demand during the previous parking process
.
The water-based purge-free grease cleaning machine includes a dosing device and an oil-water separator.
It uses water-based purge-free grease cleaning (RFC-1) technology, uses water as a solvent carrier to dissolve the cleaning agent in the water, and then uses the inorganic Or the dissolution, complexation, and transformation of organic solvents make it easier for grease stains to be separated from the surface of the equipment
.
Using the device process and temporary pipelines, technicians connect the cleaning equipment to the water-based purge-free grease cleaning machine to establish a circulation process that can effectively remove oil and achieve the cleaning purpose
According to statistics, this cleaning saves more than 5,000 tons of purge steam, and the entire operation process has a small amount of work and a low degree of difficulty, which greatly reduces the work intensity of the operators
