About AGZ

Wuhan AGZ Technology Co., Ltd., founded in 2018 in Wuhan, China, is a world-class high-tech enterprise specializing in proprietary technology and equipment for oil slurry electrical separation and deconsolidation. In collaboration with the U.S.-based LaBaer company, AGZ has pioneered a revolutionary approach to oil slurry treatment. Through extensive research and development, LaBaer redefined traditional filtration methods by applying advanced electromagnetic field science, resulting in the innovative DiSep® electrical separation technology. This cutting-edge solution effectively removes fine solid particles and metal compounds from oil slurry, addressing a long-standing challenge in China’s petrochemical industry.

As the sole authorized provider of LaBaer’s electric separation industrial equipment in China, AGZ is leading the promotion and deployment of DiSep® technology across the Chinese market. Currently, AGZ has successfully implemented several large-scale oil slurry deconsolidation projects, processing 500,000 tons of oil slurry annually. The clarified slurry, reduced to less than 50 ppm of solid content, represents a significant advancement for the industry. With DiSep® oil slurry deconsolidation technology, AGZ is set to deliver world-class solutions to China’s petrochemical sector, addressing critical industry needs with unmatched precision and efficiency.

Social & Environmental Protection

Since its inception, AGZ has prioritized solving China’s oil slurry deconsolidation challenge and addressing the environmental pollution caused by oil slurry. With a catalytic cracking capacity of 300 million tons, China leads the world, producing approximately 15 million tons of catalytic oil slurry annually. This slurry contains 3,000 ppm of catalyst powder—equating to 3 kg of catalyst powder per ton of oil slurry. Due to the lack of effective deconsolidation technologies for FCC (Fluid Catalytic Cracking) slurry, a significant portion of untreated slurry is used as low-cost heavy fuel oil, contributing to severe pollution. Nearly half of the fine powder particles are less than 2.5 microns (PM2.5), a major concern for air quality, as even burning one ton of slurry can pollute hundreds of thousands of cubic meters of air, exceeding acceptable PM2.5 limits. In contrast, as early as the 1970s, Europe and the U.S. set strict fuel oil solid content limits at under 120 ppm. The burning of untreated oil slurry results in more pollution than the combustion of hundreds of millions of tons of gasoline and diesel combined.
