2. Project Overview and Scope of Comparative 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‑reduction 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‑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 governed by 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 the 1-million-ton-per-year salt‑production facility of Chongqing Sote Salt Chemical Co., Ltd., which includes the upgrading and retrofitting of both the brine‑purification unit and the salt‑production unit, with a five‑effect configuration. Key construction items for the brine‑purification unit comprise: the erection of a complete new set of production facilities, including four first‑stage and four second‑stage reaction‑clarification tanks; the concurrent construction of a lime‑storage and lime‑slurry‑preparation system, a reaction‑sludge‑treatment system, material‑conveying equipment and process piping, as well as storage facilities for raw and auxiliary materials; and the simultaneous installation of carbon‑dioxide gas‑supply equipment, associated pipelines, and ancillary infrastructure. For the salt‑production unit, the main construction elements include: optimizing the feed‑in method by switching from counter‑current to co‑current feeding; adding preheating units for brine and condensate; modifying the mother‑liquor, circulation, and settling pipelines of each effect; and refining the structure of the salt foot. Additionally, the mixed condenser, circulating water system, secondary steam system, and non‑condensable gas system will be comprehensively upgraded; the existing hot‑water pump, hot‑water tank, and mixed‑condensation vacuum system will be decommissioned, while a deoxygenator will be installed. Furthermore, the operating pressure of the heating chamber in Effect I will be increased, and a review will be conducted to assess whether existing equipment can be reused or replaced. 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 design, process equipment, civil engineering, utility systems, fire protection, safety measures, energy‑saving strategies, environmental protection, investment estimation, and financial evaluation.
