Digital delivery technology and methods have matured internationally. Domestic digital engineering delivery is being practiced. In addition to satisfying enterprise users in the basic data correlation, digital delivery should also be practical to meet the requirements and expectations of the chemical industry for establishing digital factories and even intelligent factories in the future. Under the guidance of “double carbon” strategy, the chlor-alkali industry has been defined as a high energy-consuming industry. As such, it is urgent to conduct carbon and energy control, strive to build a new generation of digital factories, promote the path and system optimization in the digital transformation and conduct the integration design throughout the industrial chain and life cycle from design, operation, maintenance and other aspects.

Bluestar (Beijing) Chemical Machinery (BCMC) has been committed to the development strategy of international engineering services being more specialized and intelligent. To meet the new requirements of chlor-alkali customers for safety, environmental protection, energy saving and high efficiency, BCMC has invested nearly 10 million yuan in R&D, introduced AVEVA design platform and established the first digital factory in the chlor-alkali industry. The enterprise has specialized in logic design, 3D collaborative design, engineering material management, plant digital management, process monitoring and control management, predictive maintenance & management of equipment, and process optimization to offer customized services to other enterprises. It has improved its efficiency as a whole, filled the digital delivery gap in the chlor-alkali industry, built an internal 3D digital transfer operation center, and provided the digital management and whole lifecycle support for production.

Enterprise users can obtain timely and reliable information on plant construction and operation to improve management capabilities in the construction period. They can optimize the process of data transfer, improve data transfer quality, and reduce costs of data transfer and processing. They can achieve low-cost, high-quality and fast start-up while accumulating knowledge for future operation, maintenance, renovation, life extension, and decommissioning. They can reduce equipment downtime, enhance the overall efficiency of plant operation, and cut the overall costs.

BCMC has provided long-term services for other enterprises through cloud-based model maintenance, transformed digital delivery from static data to whole lifecycle delivery services, and enabled plant configuration management for a truly digital factory, delivering a basic platform and carrier to smart factories.

Recently, BCMC undertook the EPS general contracting project of a digital chemical plant with an annual production of 120,000-ton caustic soda. The project has given full play to the advantages of digital engineering design, creatively utilized AVEVA software to facilitate the owner’s remote access to engineering data during the construction period and fed it back to the company’s designers. The cloud library of the project has been established, with the digital twin service model consistent with the cloud data, enabling an intelligent dialogue between devices. The project achieved digital delivery and intelligent operation and became China’s first “Digital Chlor-alkali Plant”.

Throughout the entire lifecycle, the digital delivery design of plants based on the cloud platform won the Excellent Innovation Achievement Award of Lunjian National Industrial Digital Technology Innovation Contest 2021.

BCMC’s first EPS turnkey project chlor-alkali digital factory construction solution has transformed the digital delivery from static data delivery to plant-based whole lifecycle delivery services, realizing a truly digital factory. The company has also provided a fundamental platform and carrier for developing intelligent factories. This will be a starting point and new development trend for developing China’s digital intelligent factories in China’s future chlor-alkali industry.
