2. Project Overview and Scope of Competitive Selection
2.1 Project Location: Salt Production Section, Salt Manufacturing Division, Chongqing Suote Salt Chemical Co., Ltd.
2.2 Project Scope: Preparation of the feasibility study report for the energy‑saving and consumption‑reducing technical renovation project of the salt‑production system at Chongqing Suote Salt Chemical Co., Ltd., to support an annual raw salt production capacity of 1.5 million tonnes via vacuum evaporation. The scope includes the construction of one new brine‑purification unit, encompassing but not limited to site master planning, civil engineering, process equipment, installation works, utility systems, as well as associated electrical, instrumentation, automation and intelligent control systems, fire protection, safety measures, environmental protection, investment estimation, and financial evaluation. Specific details shall be subject to the minutes of the joint meeting attached hereto.
2.3 Project Duration: The completed feasibility study report shall be submitted within 60 calendar days from the date of contract signing (subject to Party A’s specific requirements).
2.4 Project Scope: The technical renovation project for optimizing the 1 million-ton-per-year salt‑production facility of Chongqing Suote Salt Chemical Co., Ltd., which includes comprehensive upgrades to both the brine‑purification unit and the salt‑production unit, specifically the five‑effect evaporator system. Key construction items for the brine‑purification unit comprise: the erection of a complete new brine‑purification production line, including four first‑stage and four second‑stage reaction‑clarification tanks; associated facilities such as a lime storage and lime‑milk preparation system, a reaction‑sludge treatment system, material‑handling equipment and process piping, and a raw‑and‑auxiliary‑materials warehouse; concurrently, carbon‑dioxide gas‑supply infrastructure, pipelines, and ancillary supporting facilities will be constructed. For the salt‑production unit, the main works involve: optimizing the feed‑in method by switching from counter‑current to co‑current feeding; installing additional preheating equipment for brine and condensate; modifying the mother‑liquor, circulation, and settling pipelines of each effect; and refining the salt‑foot structure. Furthermore, the mixed condenser, circulating‑water system, secondary‑steam system, and non‑condensable‑gas handling system will undergo comprehensive upgrades; the existing hot‑water pump, hot‑water tank, and mixed‑condensation vacuum system will be decommissioned, with a deoxygenator newly installed. In addition, the operating pressure of the heating chamber in Effect I will be increased, and a thorough review will be conducted to determine whether existing equipment can be reused or needs replacement. Both the brine‑purification unit and the salt‑production unit will achieve intelligent and automated operation. The scope encompasses, but is not limited to, site‑plan layouts, process equipment, civil‑engineering works, utility systems, fire‑protection measures, safety protocols, energy‑saving initiatives, environmental protection requirements, investment estimates, and financial evaluations.
