Guide for Process Design, Cost and CO2 Emission Estimation with Relevant Database:
Structuring Knowledge Base on Equipment, Material and Cost Information

Summary

 This document is intended to guide the paths towards process design, cost and CO2 emission estimation with relevant database in order to realize the quantitative analysis on the low-carbon technologies whose frame has been described ( “Comprehensive strategies and scenarios for building a low-carbon society”, July 2012) [1].

 In order to evaluate the performance of low-carbon processes (mainly manufacturing costs and environmental impact), the process design procedure is useful. In general, process design will start to decide the design base such as capacity and specification of the aimed product, boundary conditions such as incoming and outgoing of raw materials, utilities, product, by-product and effluents. Then, process flow diagram (PFD) with operating condition, material balance and heat balance process will be created by utilizing the physical chemistry knowledge, experimental data and so on. Next step is to select the type of equipment and determine its specification. Based on the above mentioned knowledge, production cost is calculated as well as environmental impact.
 In this paper, following items are described.
 1. Selection of the type and specification of process equipment
 2. Calculation of production costs
 3. The calculation of the environmental impact
