Fujian Yongrong Technology currently has a caprolactam production capacity of 280,000 tons in Phase I, and 300,000 tons in Phase II. Currently, the second-phase capacity expansion and renovation are underway. The capacity after the renovation is 370,000 tons. The planned Caprolactam Phase III project will have a production capacity of 350,000 tons. The total capacity of the entire plant is 1 million tons. One set of methanol-to-hydrogen plant for Phase I project. With a capacity of 20,000 m3/h, the methanol-to-hydrogen plant utilizes methanol cracking and PSA pressure swing adsorption technology. One set of sulfuric acid plant. A \"3+2\" five-stage two-conversion, two-absorption process is adopted, with imported catalysts used. The capacity is 300,000 tons per year. One set of hydrogen peroxide plant. It adopts the anthraquinone hydrogenation technology, with a capacity of 240,000 tons per year. One set of cyclohexanone plant. The route of producing cyclohexanone from cyclohexene is adopted. Technology for the partial hydrogenation of benzene to produce cyclohexene, the hydration of cyclohexene to produce cyclohexanol, and the dehydrogenation of cyclohexanol to produce cyclohexanone. The capacity is 227,000 tons/year (of which an additional 10,000 tons/year is under construction as part of a capacity expansion). One set of caprolactam plant. Cyclohexanone oxime is produced using an ammonia oximation process route, involving multi-stage rearrangement and neutralization crystallization techniques. The capacity is 280,000 tons per year. One set of cyclohexane dehydrogenation unit. Cyclohexane is dehydrogenated and purified into product benzene and product hydrogen. One set of coal-to-hydrogen and ammonia synthesis units for the second-phase project. It employs space furnace gasification, shift reaction and low-temperature methanol washing for carbon removal, pressure swing adsorption for hydrogen production, the Keyang wet process for acid production, liquid nitrogen washing, and domestic low-pressure ammonia synthesis technology. The ammonia production capacity is 300,000 tons per year, while the hydrogen production capacity is 40,000 m3/h. One set of sulfuric acid plant. A \"3+1\" four-stage, two-transformation, two-absorption process is adopted, using imported catalysts. The capacity is 480,000 tons per year (an additional 80,000 tons per year will be added through expansion, currently under construction). Two sets of hydrogen peroxide systems. The anthraquinone hydrogenation technology is employed. The scale is 30% hydrogen peroxide at 2×250,000 tons per year. One set of cyclohexanone plant. The existing route for producing cyclohexanone from cyclohexene is still used: benzene is partially hydrogenated to produce cyclohexene, cyclohexene is hydrated to yield cyclohexanol, and cyclohexanol is dehydrogenated to produce cyclohexanone. The capacity is 1×350,000 tons per year (an additional 50,000 tons per year will be added through expansion, currently under construction). One set of caprolactam plant. Cyclohexanone oxime is produced using the ammonia oximation process, along with multi-stage rearrangement and neutralization crystallization techniques. The caprolactam plant has a capacity of 1×370,000 tons per year (with an additional 70,000 tons per year added through expansion, currently under construction).
