Based on the URS and physical property analysis provided by the customer, we can design the PFD process flow chart, including production process, capacity calculation, unit operation, etc. After the PFD is completed, we will design P&ID diagrams to provide a more detailed description of the process, instrumentation and utilities; At the same time, technical specifications for process equipment and utility equipment in the process production system are also presented. At the same time, during the whole process design process, we will conduct several audits to ensure that the design meets the requirements of the customer's URS.
