Author/Source: Date: 2022-11-14. Clicks: 43. 1. Bid Requirements: The bidder for this bid project (re-bid) – namely, the ammonia refrigeration compressors for the integrated optimization project of hydrogen production and ammonia synthesis at Nanjing Chemical Industry Co., Ltd. (WZ20221206-2333-16301-B1) – is the company itself; the funds required for this project come from the company’s own capital, with a contribution rate of 100%. The project is now ready for bidding, and a public tender is being conducted for the procurement of ammonia refrigeration compressors. 2. Project Overview and Scope of Bidding 2.1 The project has been approved and the funding has been secured. 2.2 Scope of the tender: 2.3 Technical specifications: The technical specifications are detailed in the specific tender documents. 3. Qualification requirements for bidders: 3.1 For this tender, bidders must meet the qualifications, experience, and other requirements specified in this paragraph, as well as possess the capacity to supply goods relevant to this tender project. 3.1.1 The bidder shall possess a business license, tax registration certificate, and organization code certificate, or be registered under the \"three-in-one\" registration system, with valid licenses. 3.1.2 By the bid deadline, the bidder has not been included by the administrative department for industry and commerce on the list of enterprises with serious violations of laws and dishonesty in the **Enterprise Credit Information Publicity System ； Nor has it been included on the list of dishonest defendants on the \"Credit China\" website. 3.1.3 The bidder is not under a period of risk suspension or suspension due to breach of contract imposed by Sinopec. 3.1.4 The bidder has not been ordered to suspend operations, have its licenses temporarily seized or revoked, or have its permits temporarily seized or revoked ； There is no situation of entering liquidation proceedings, being declared bankrupt, or otherwise losing the ability to fulfill obligations. A letter of commitment signed by the legal representative or an authorized representative and stamped with the official seal must be provided. 3.1.5 The bidder has not experienced any major safety-related incidents in the past two years. A letter of commitment signed by the legal representative or an authorized representative and stamped with the official seal must be provided. 3.1.6 The bidder’s qualifications must meet the requirements of 4.1.1, including but not limited to: providing certifications for occupational health and safety management systems, environmental management systems, and quality management systems that are still valid; as well as providing copies of the \"Special Equipment Manufacturing License (Pressure Vessels) of the People’s Republic of China\" for the manufacture of pressure vessels of Class II and above (manufacturers’ licenses are also acceptable). 3.1.7 The ammonia compressors (screw type) provided by the bidder shall be proven-to-be-robustly-designed models, with at least two instances of successful operation in China’s coal chemical industry over a period of 2 years or more within the past 5 years (2018–2022), such that these records can be verified on-site. The performance requirements for the model to be used must be no lower than those of the model submitted in this bid; the refrigerant to be used is liquid ammonia, and it should feature a two-stage refrigeration system (with two compressors operating in series at high and low pressure levels). There should be no oil pump, as automatic oil supply for lubrication is achieved through pressure differences during normal operation. The system must have functions for load regulation via slide valves as well as regulation of the volume ratio. The compressors’ bearings must be friction-resistant fully rolling bearings. Copies of the contract, technical agreement, and corresponding invoices are required, as well as copies of relevant performance verification documents (which must be signed and stamped by the client unit and include their contact information). Any absence of one of these documents will result in rejection of the application. 3.1.8 The compressors for this project are required to be supplied in skid form. The structure, external dimensions, and interface positions of these skids must meet the requirements specified in 4.1.8. This includes, but is not limited to, the fact that the compressors shall be installed in the designated areas within the existing compressor plant. Due to the limited space inside the plant, the external dimensions of the new compressors should be as similar as possible to those of the existing ones, and must not exceed 9000×4200×4200 mm (length×width×height) ； Due to the limitations of the lifting equipment in the unit building, the maximum weight of a single repair item for the unit must not exceed 5 tons ； Given that the suction buffer tank, condenser, and liquid storage tank will be shared with the existing units, as well as considering the requirements for on-site piping, the positions of the connection ports on the new compressor unit skids must match those of the original units. 3.1.9 The compression unit for this project is required to utilize a two-stage refrigeration system, with the high-pressure and low-pressure compressors operating in series ； Oil-free pump design; automatic oil supply and lubrication via pressure difference during normal operation ； All compressors are twin-screw compressors driven by motors, capable of operating under both 4°C and -40°C conditions; furthermore, the process parameters at the inlets of the low-pressure and high-pressure stages must remain consistent with those of the existing units ； When the low-pressure stage is not in operation, the high-pressure stage can operate independently, with inlet process parameters identical to those of the low-pressure stage inlet. 3.1.10 The compression unit of this project shall be equipped with a complete and reliable process control and safety interlock system. Functions such as start-up, shutdown, and adjustment shall be carried out by the buyer’s DCS system, while the safety interlock system shall be provided by the tenderer’s SIS system. The bidder is responsible for carrying out the design related to process control and safety interlocks, and providing the technical data required for the tenderer’s system configuration (including content volume ratio control), as well as control flow charts, cause-and-effect diagrams, etc. 3.1.11 The bearings of the compressors for this project must be anti-friction full-rolling bearings, in order to effectively reduce operating power consumption; the standard design life is 100,000 hours at the L10 level. 3.1.12 The bidder must provide responses indicating that it meets each of the requirements specified in the tender document, or provide responses that are more favorable to the tenderer; any failure to provide responses, incomplete responses, or unsatisfactory responses will result in disqualification. 3.1.13 Bidders for this project must be ammonia compressor manufacturers capable of independently carrying out the entire process, including the design and production of the compressor itself and its skid units, system integration, commissioning testing, after-sales service, and training. The bidder shall commit to being responsible for the installation, commissioning, system assembly, trial operation, online testing, long-term operation support, and supply of spare parts for the purchased equipment. Bids from distributors and agents are not accepted, nor are bids from consortia. 3.1.14 Bids submitted by different entities that have the same person in charge, or that are in a controlling or managerial relationship with each other, will be rejected. 3.1.15 Other conditions required by laws and regulations. 3.1.16 For detailed requirements, please refer to the tender documents. 3.2 Joint bids are not accepted for this tender. 3.3 This tender accepts applications from producers/manufacturers; bids from agents are not accepted, nor are bids from distributors. 4. Acquisition of Tender Documents 4.1 All those interested in bidding are requested to *download the electronic tender documents from 9:00 on November 12, 2022, to 17:00 on November 18, 2022 (Beijing time, the same below). 4.2 The price of each set of tender documents is 200.00 yuan, and no refund will be provided after purchase.
