Experts, could you please explain the general sequence involved in a gasification project (4 billion cubic meters per year), from the initial planning stage to operation? For example, once the environmental impact assessment is approved, what should be the next step? A contract for the preliminary design is signed with the design institute – what does this preliminary design include? Will an EPC contract be signed after the preliminary design is completed? What is the sequence for purchasing equipment for the entire gasification project? What are some of the long-cycle devices that were developed first? What is the procurement sequence for other equipment? The more detailed, the better. Thank you!
Project approval, introduction of process packages, preliminary design, approval of preliminary design estimates, detailed design (EPC). The procurement process can be initiated once the data sheet for long-cycle equipment arrives. The procurement procedures vary depending on the type of enterprise.
The \"Unified Regulations for Basic Design of Petrochemical Engineering\" specify the required depth of basic design. Besides, since a contract has been signed with the design institute, it should have a detailed project plan as well.
After the preliminary design is completed for a large-scale project, a further initial design is required, along with an review of that initial design. The EPC contractor then submits bids, which include both commercial and technical aspects. Following this is a lengthy bidding evaluation process; after it’s complete, a decision is made regarding the winner based on factors such as the Rationality of the bidder’s design proposals and the fairness of their pricing. Once a winner is selected, an EPC contract is signed to proceed with the detailed design. In this phase, the overall layout, underground piping diagrams, and related construction work must be completed first. Next, it’s necessary to procure long-term-use equipment, equipment sourced through international tenders, as well as equipment that affects the structural and civil engineering designs. The equipment manufacturers provide the necessary basic data for use in the design process. After that, civil and structural drawings are prepared, and non-standard equipment needs to be purchased promptly (especially for projects in cold northern regions). Once the equipment arrives at the site, it must be installed quickly to prepare for the construction of the enclosed factory structure.
