The Shenma Project’s 1,000-ton high-temperature nylon 6T resin renovation project has been approved! 2025-08-09 On August 5, the draft environmental impact assessment report for the high-temperature nylon 6T resin modification project at Pingdingshan Shenma Engineering Plastics Co., Ltd. was made public for approval. The main products currently produced at the plant are nylon 66 chips. The plant’s nylon 66 chip production facilities include 2 sets of batch polymerization units (with capacities of 23,000 tons per year and 30,000 tons per year respectively), as well as 2 sets of continuous polymerization units (with capacities of 20,000 tons per year and 30,000 tons per year respectively). The 23,000-ton-per-year batch polymerization unit was shut down in May 2023; thus, the company’s actual total production capacity for nylon 66 chips is 80,000 tons per year. The existing facility has passed the clean production audit, and its current level of clean production is among the advanced levels in China. Project Overview Project Name: High-temperature Nylon 6T Resin Modification Project of Pingdingshan Shenma Engineering Plastics Co., Ltd. Construction unit: Pingdingshan Shenma Engineering Plastics Co., Ltd. Construction type: Renovation. The 23,000-ton batch polymerization unit was shut down in 2023; the company plans to renovate this unit, with this renovation project involving the replacement of the 1,000-ton capacity portion of it. The project is constructed in the eastern part of the 23,000-ton intermittent polymerization plant. Industry category: C2651 Manufacturing of primary plastic and synthetic resin products. Construction location: The eastern part of the 23,000-ton intermittent polymerization plant within Pingdingshan Shenma Engineering Plastics Co., Ltd., in the Pingdingshan High-Tech Industrial Development Zone. Construction scale: Annual production of 1,000 tons of high-temperature nylon. Floor area: The total floor area is 550 m2. Project investment: The total investment in the project is approximately 33 million yuan, of which 2.8 million yuan is allocated to environmental protection measures, accounting for 8.48% of the total investment. The total investment for the project is 33 million yuan, with a design capacity to produce 1,000 tons of high-temperature nylon resin. The project plans to renovate floors 1–4 of the existing, now defunct 23,000-ton intermittent polymerization plant on its east side; this renovation will replace the production capacity of 1,000 tons, while the remaining 22,000 tons of production capacity will be upgraded in line with the company’s development plans. Some floor slabs are intended to be removed, new high-temperature nylon production equipment will be installed, along with environmental protection facilities, utility systems, and fire safety measures. The project has 1 set of production equipment and 4 types of products. The main raw materials include hexamethylenediamine, adipic acid, terephthalic acid, isophthalic acid, sodium hypophosphite, etc. The main equipment includes a salt formation reactor, a concentration reactor, a flash drum, a complete set of granulation units, reaction vessels, cyclone separators, heat transfer pumps, heat exchangers, etc. The heat transfer oil furnace is heated by natural gas. The production processes for the four products of this project are basically identical; the main difference lies in the proportions of raw materials used. The key processes include salt formation, pre-polymerization, flash drying and granulation, final polymerization (polycondensation through heating in a heat transfer oil furnace), and packaging.
