Scope of Work for Phase I of the Molecular Sieve Expansion Project at Luoyang Tianping Molecular Sieve Co., Ltd.

Public Notice of Completion of Supporting Environmental Protection Facilities

The first phase of the molecular sieve expansion project at Luoyang Tianping Molecular Sieve Co., Ltd. has been completed, and our organization intends to conduct a phased environmental protection acceptance inspection upon its completion. In accordance with current environmental protection policies and EIA requirements, the plant’s auxiliary facilities for treating waste gas, wastewater, and controlling noise pollution have been constructed. In compliance with relevant regulations, we hereby publicly announce the completion status of the project’s supporting environmental protection facilities, as follows:

I. Project Overview:

1. Project Name: Phase I of the Molecular Sieve Expansion Project of Luoyang Tianping Molecular Sieve Co., Ltd.

2. Project Location: North side of Daonan Road, Petrochemical Industrial Park, Advanced Manufacturing Development Zone, Mengjin District, Luoyang City (formerly the Petrochemical Industry Cluster Area of Luoyang City, Henan Province)

3. Nature of the construction project: renovation and expansion

II. Project Scope:

1. The total investment for the first phase of the project is RMB 4.5 million, of which RMB 2.1 million is allocated to environmental protection.

2. Environmental protection facilities for the project: (1) Production Workshop 1: Exhaust gases from the mesh‑belt dryer’s loading and unloading processes are treated by one baghouse dust collector (shared with the original molding process); flue gases from gas combustion, after low‑NOx combustion, are discharged through the existing stack. (2) Production Workshop 3: ① For the expansion project, molding exhaust is collected via hoods and centrally captured, then processed by two baghouse dust collectors before being discharged through a 15‑m‑high stack; ② The two existing calcination furnaces and the newly added vibrating fluidized bed—along with their loading and unloading exhaust—are treated by two baghouse dust collectors; flue gases from gas combustion all employ staged pre‑mixing low‑NOx combustion technology, with emissions discharged through a 15‑m‑high stack; ③ The two expanded calcination furnaces’ exhaust is likewise treated by two baghouse dust collectors, with flue gases from gas combustion utilizing staged pre‑mixing low‑NOx combustion technology, and discharged through a 15‑m‑high stack. (3) Finished‑goods warehouse: Packaging exhaust is collected by hoods, treated by one baghouse dust collector, and discharged through a 15‑m‑high stack. (4) Boiler room: The newly installed 3‑t gas‑fired boiler is equipped with a low‑NOx burner and discharges its flue gases through a 15‑m‑high stack. (5) ① Alkaline wastewater generated during the washing of 5A molecular sieve after crystallization, low‑concentration saline wastewater from ion‑exchange cleaning, and acidic/alkaline laboratory wastewater are treated at the existing production wastewater treatment plant prior to discharge. ② Wastewater from purified water production, periodic boiler blowdown, and resin regeneration in purified water production is directly discharged into the park’s sewage network. ③ Domestic sewage is treated and discharged using the existing integrated treatment facilities. ④ High‑concentration saline wastewater produced during the ion‑exchange process for 5A molecular sieve is sent to a triple‑effect evaporator; the resulting mother liquor is recycled, condensate is reused, and the crystallized salt is sold as a byproduct.

III. Completion Date: The environmental protection facilities were completed on January 10, 2025.
