Powerful! Deeply purified 40,000 liters of oil in a large ethylene facility within 20 days, boosting the company's efficient production!

Three Ethylene Cracking Units

Cracker gas compressors, propylene compressors, and ethylene compressors

The "heart" equipment of the cracking unit in the chemical industrial zone.

The performance directly impacts production load and economic benefits.

The quality of the oil is crucial to the operation of the aircraft.

Due to the prolonged operation of the crew under high temperatures, pressures, and high speeds.

The rate of oil oxidation is accelerating continuously.

It will lead to film buildup and increased temperature.

Severe cases may severely impact the safety and production of aviation personnel!

How to efficiently remove paint film and reduce the water temperature?

01Electrostatic Adsorption + Ion Resin Technology for Paint Film Removal

Weishengda's Anti-Film Purification Unit for lubricants containing varnish and胶质 materials effectively combines electrostatic adsorption purification technology with ion exchange technology. It efficiently removes and prevents the formation of soluble and non-soluble oil sludge generated during the normal operation of large-scale equipment, thereby preventing the formation of varnish. Through Weishengda's electrostatic adsorption technology, suspended varnish and fine particles can be quickly removed, and the exchange groups on the ion resin can effectively adsorb the dissolved varnish in the oil.Quickly resolves issues like shaft bearing temperature fluctuations caused by paint film, strips and removes suspended and dissolved paint film, MPC ΔE ≤ 10, deep cleaning, improves system operating environment, cleanliness maintains ≤ NAS 5 level, extends lubricant life, reduces unplanned downtime and maintenance costs.

Electrostatic Adsorption for the Removal of Non-Dispersible Oil Sludge/Lacquer Film

The WJD technology for electrostatic adsorption of non-dissolvable sludge/film effectively removes insoluble pollutants at an early stage in the oil degradation process. Numerous case studies demonstrate that the electrostatic adsorption principle can attract both hard and soft pollutants through the flow of charged particles in the system during the oil circulation process, keeping your system free from sludge/film contamination. Compared to similar technologies, Weishengda's environmental protection electrostatic adsorption technology can at least accelerate the removal rate of sludge/film by...200%。

Ion Adsorption Technology for Removing Soluble Colloidal Substances

Ion exchange resin technology can remove soluble pollutants. Shear stress in the lubrication system leads to the automatic degradation of oil quality, which is the fundamental cause of sludge/film contaminants. When these stresses are present, they cause soft contamination, leading to control failure. The by-products of oil degradation are highly soluble and not suitable for removal by electrostatic adsorption equipment. However, the ion adsorption-DICR™ technology is fully capable of removing the soluble pollutants from the oil.

02Weishengda's actual treatment effect of the paint film cleaner oil separator

A petrochemical client's ethylene unit has significant production capacity, demanding high standards of safety, stability, and continuity in operation. Due to the heavy load and high temperatures of the equipment, the oil gradually oxidizes and particle contaminants increase over time, leading to a gradual rise in the bearing temperature within the unit, which is detrimental to the equipment's safety. Replacing the oil is costly, and a device capable of addressing cleanliness and oxidation issues is required to ensure long-term stable operation. To help the client address current pain points and maintain the long-term stable operation of the equipment, the client introduced the Weishengda Anti-Film Oil Purifier. Before installing the Weishengda Anti-Film Oil Purifier, a sample of the in-use oil was taken from the equipment. After 20 days of operation of the purifier, another sample was taken from the equipment.

Two batches of lubricants were sent for third-party testing, revealing an improved cleanliness to NAS 4 level, a decrease in the paint film tendency index (MPC) to 2, and noticeable purification effects within just 20 days for 24,000 liters of lubricant.
