Focusing on the chemical industry, we have continuously explored and deepened our expertise in the "one salt, two alkalis" value chain. We possess proprietary technologies in the consulting, design, EPC contracting, and production of the following chemical products: membrane-cell caustic soda, allyl chloride, epichlorohydrin (via chlorohydrin, glycerol, and direct hydrogen peroxide oxidation routes), ethylene dichloride (via direct chlorination and oxychlorination), vinyl chloride, polyvinyl chloride, chloroacetic acid (continuous process), chlorinated methanes, methyl chloride (liquid-phase process), trichlorosilane, carbon emission reduction (soda ash production from flue gas), propylene oxide, and oxidative dehydrogenation butadiene.

The novel direct hydrogen peroxide oxidation technology effectively addresses the pollution issues of traditional processes, complies with national environmental protection policies, and offers broad industrialization prospects. It enables the resourceful utilization of high-salinity wastewater and waste hydrochloric acid, establishing a new circular economy model.

The vinyl chloride process technology package via the ethylene route employs direct chlorination and oxychlorination of by-product HCl to produce ethylene dichloride (EDC), followed by EDC cracking to vinyl chloride (VCM). The production process aligns with national industrial policies, and all key equipment can be domestically manufactured. Its main technical indicators have reached internationally comparable levels, delivering excellent economic and environmental benefits.

The chloroacetic acid process package utilizes a continuous acetic anhydride-catalyzed chlorination process, yielding higher-purity products while conserving energy.
