Invitation for Quotation and Comparison on the Preparation of the Feasibility Study Report for the Optimization and Energy-Saving Project of the Ammonia Gas System from Xiangyu Salt & Chemical Synthesis to Combined Alkali, as well as the Upgrade and Renovation Project of the Combined Alkali Ice Machine

To reduce costs and improve efficiency, our company plans to optimize the gas ammonia process from synthetic to combined alkali production at Xiangyu Salt & Chemical. At the same time, we will upgrade and technically reconfigure the ice machines currently in use at the combined alkali plant. The preparation of feasibility study reports for these two projects is proposed to be carried out through a request-for-quotation and price-comparison procurement process to select the consulting service provider. We hereby invite your company to participate in the bidding for the preparation of these feasibility study reports. Please provide a quotation for the fees required for the preparation of the consulting services.
I. Project Overview:
1. Project Location: Within the premises of Xiangyu Salt & Chemical Co., Ltd., No. 98 Longxiang Avenue, Wanzhou District, Chongqing City.
2. Project Overview:
(1) Optimize and upgrade the existing gaseous ammonia process at Xiangyu Salt & Chemical: Specifically, by adding a low-power, low-Methanol gas ammonia booster compressor, the gaseous ammonia from the low-temperature methanol wash will no longer be compressed through three stages. Instead, it will be boosted in temperature and pressure by this new compressor and then sent to the combined alkali ammonia absorption unit. The gaseous ammonia from the combined alkali ammonia cooler—equal in quantity to the amount absorbed—and the gaseous ammonia from the first ammonia cooler will be mixed together and fed into the combined alkali ice machine. After being boosted and heat-exchanged, the mixture will be sent to the liquid ammonia storage tank.
(2) Upgrading and replacing the ice machines currently in use at the Xiangyu Salt & Chemical Ice-Making Plant—replacing five screw-type ice machines with a single large-scale centrifugal ammonia refrigeration unit—can reduce the overall power consumption of the ice-making system, thereby achieving energy savings and lowering operating costs.
The total construction cost of the above two projects is approximately 40.5 million yuan, and the construction period is two years.
II. Preparation Requirements and Content:
Based on the renovation technical plan described above, prepare a project feasibility study report. The prepared feasibility study report must comply with relevant national policies, standards, codes, and regulations pertaining to project construction, and must meet the requirements for project approval submitted to the administrative department of the Economic Development Zone in Wanzhou District, Chongqing. Additionally, you will be responsible for passing the expert review of the feasibility study report and cooperating to complete all related procedures for project filing, approval, and project initiation.
III. Relevant Consulting Qualifications and Construction Period Requirements:
Bidding entities must possess Grade B or higher design qualifications in the chemical, petrochemical, and pharmaceutical industries.
Project feasibility study report submission deadline: 40 days.
4. Quotation Method and Requirements for Quotation Materials:
1. The consulting service fee for this project will be awarded through a single-round bidding process involving price comparisons. The total quoted amount already includes taxes (tax rate: 6%, with special VAT invoices), expert review fees, and other related expenses.
2. The quotation materials must include:
Your company’s business license, relevant qualification documents (photocopies stamped with the company’s official seal), and the “Quotation Letter” and “Itemized Quotation Table” attached to this invitation letter (both stamped with the company’s official seal).
