Safety Pre-evaluation Report for the Comprehensive Energy-Saving Renovation Project of the Xiangyu Salt & Chemical Ammonia System and Wastewater Treatment System (Second Price Comparison)

Our company’s safety pre-assessment design for the comprehensive energy-saving renovation project of our ammonia system and wastewater treatment facilities is planned to be carried out through a request-for-quotation and price comparison procurement process to select the design service provider. We hereby invite your company to participate in the bidding for design services and kindly request that you provide a quotation for the fees required for the project’s design services.
I. Project Overview:
1. Project Location: Within the premises of Chongqing Xiangyu Salt & Chemical Co., Ltd., No. 98 Longxiang Avenue, Wanzhou District, Chongqing City.
2. Project Overview: 1. Combined-Alkali Screw Chiller Project: Within the premises of Chongqing Xiangyu Salt & Chemical Co., Ltd., a new centrifugal ammonia chiller with a rated power of 6,670 kW will be added to the combined-alkali unit. The existing seven screw chillers at the combined-alkali unit will be decommissioned, as will the current ammonia chiller at the synthetic ammonia unit. 2. Gas Ammonia System Project: A new low-power, low-temperature methanol wash gas-ammonia booster compressor will be installed. Instead of passing through the three-stage ammonia compression process, the low-temperature methanol wash gas ammonia will now be boosted in temperature and pressure by this new compressor before being sent to the ammonia absorption process in the combined-alkali unit. The gas ammonia from the combined-alkali ammonia cooler—equal in quantity to the amount absorbed—and the gas ammonia from the first ammonia cooler will be mixed together and fed into the combined-alkali chiller. After being boosted and heat-exchanged, the mixture will then be sent to the liquid ammonia storage tank.
The total project construction cost is approximately 51 million yuan.
