Process Design Service Introduction
Our process design services cover the following areas:文章源自CIDIGITAL-https://www.cidrg.cn/en/services/engineering/479.html
- Participation in Engineering Design: Process engineers join client projects, providing professional advice and technical support.
- Professional Drafting: Using intelligent P&ID software such as AutoCAD, Smart P&ID, and AVEVA Diagrams, we complete the drawing and modification of PFD and P&ID diagrams.
- Process Calculations: Utilizing software like Aspen HYSYS, Aspen EDR, and HTRI, we perform material and energy balances (H&MB), equipment design and calculations, safety valve design and verification, pipeline hydraulic analysis, and flare system design.
- Document Preparation: Assisting clients in preparing key process documents such as equipment lists, line lists, and instrument data sheets.
- Procurement and Commissioning Support
- Additional Services: Providing training and technical support services for commonly used process software.

Typical Process Design Case Studies
Propylene Project Intelligent Data Conversion Case 2020 - Nanjing - SP P&ID
During the production and operation of actual plants, ongoing maintenance and modifications, as well as annual overhauls, involve continuous updates and additions to P&ID diagrams. New installations also require timely updates to reflect the actual site information in the P&ID intelligent system, ensuring consistency between the system and the site.
In 2020, after a year of organization, the client required the addition and updating of nearly 2,500 P&ID drawings, each containing approximately 300 pieces of information. The total workload involved processing over 700,000 pieces of P&ID information within two months. Due to the tight timeframe, efficient project management and quality control were essential. Despite the strict schedule, high-quality results were delivered.文章源自CIDIGITAL-https://www.cidrg.cn/en/services/engineering/479.html
Commonly Used Process Design Software
Our process design team uses a wide range of software to complete different tasks. Here's a list of some commonly used software:文章源自CIDIGITAL-https://www.cidrg.cn/en/services/engineering/479.html
