Produced in Gansu Project Feasibility Study Report Contents of scheme comparison:
1. Introduction to comparison and selection.
Comparison and selection of production process technical schemes, including demonstration of advancement, applicability, reliability, availability, safety, environmental protection and economic rationality of each technical scheme. The content of process technology scheme comparison and selection is related to industry characteristics. It is necessary to highlight innovation and technical characteristics, and attach importance to the analysis of patents and proprietary technologies.
For large combined plant projects, comprehensive selection should be made according to the overall process flow, material consumption and output, taking full account of the consumption of each unit, the exchange of materials and the matching between technologies. For reconstruction and expansion projects, the combination with the original technology should be considered. It is a way of renewal and substitution, transformation and upgrading or parallel, which should be selected after technical and economic comparison.
2. Comparison method.
The comparison and selection of process technology schemes usually adopts the combination of qualitative analysis and quantitative analysis.
First, quantitative indicators can be used for comparison and selection, mainly including the use of raw materials and auxiliary materials' material consumption indicators, energy consumption indicators, product yield, raw material loss rate, product quality (including high value-added product yield, etc.) and other indicators for technical analysis; Economic analysis is carried out by using indicators such as unit product cost, unit product investment and technology use right cost; Comprehensive analysis shall be carried out by using indicators such as floor area and personnel quota.
Secondly, it conducts quantitative or qualitative analysis on risk factors, mainly including factors affecting technological advancement, applicability and reliability, the possibility of being replaced or eliminated by other new technologies in the future, and the impact of national industrial development and environmental protection policies.
For plant wide projects (or joint projects), the plant wide general process flow scheme, production unit and scale, production unit composition and layout, and plant wide material balance analysis shall be carried out.
The comparison and selection of process technology schemes can be described in words or in the form of process technology comparison table.
Recommend the scheme after comparison. The process flow of the recommended scheme shall indicate the name of main equipment, main materials, fuel flow and flow direction. If the project is planned once, constructed and put into production by stages, the description and flow chart of the stage process shall be provided. If your enterprise needs Lanzhou Feasibility Study Report Compilation can call for consultation at any time.
