Process stability is the basis for the sustainable development and innovation of hazardous chemical production enterprises. The status quo of process management in chemical production enterprises, the construction of GB/T 44693 "Process stability of hazardous chemicals enterprises" comprehensive management system, innovation and upgrading The first-level process management model builds a scientific, efficient and standardized process operation control mechanism to effectively prevent and resolve hazardous chemicals. To reduce major safety risks in manufacturing enterprises, it is of great significance to ensure the smooth and safe production process. GB/T 44693 "Process Stability of Hazardous Chemicals Enterprises" is intended to consist of the following 6 parts.

1.Management guidelines. The purpose is to determine the general principles and relevant requirements that need to be followed for process stability management.

2.Technical specification for control loop performance evaluation and optimization. The purpose is to provide control loop performance evaluation and optimization for process stability management. Provides actionable and verifiable methods for assessment and optimization.

3.Standard operating procedures preparation and use specifications. The purpose is to clarify the standard operating procedures in process stability management (Work Instructions) Principles and requirements that need to be followed in writing and using.

4.Start-up process management specifications. The purpose is to determine the requirements for the start-up management of the device in process stability management. basic principles and working norms.

5.Technical specification for process alarm optimization. The purpose is to provide operational A proven method.

6.Technical specifications for key performance indicators. The purpose is to provide operational, Verifiable indicators and calculation methods. This document aims to comprehensively guide hazardous chemical manufacturers to carry out process management, and to establish a systematic thinking of process stability control. process, continuously strengthen the process management, improve the stability of equipment production, reduce abnormal fluctuations, ensure that production meets the expected goals, and continuously Improve the level of refinement and standardization of enterprise process management. Process stability of hazardous chemical enterprises Part

1 Scope

GB/T 44693.1-2024 is the management guideline part of the Chinese standard on process stability in hazardous chemical enterprises. The premise is one that Chinese process safety regulation has arrived at after a series of major accidents: most serious incidents are preceded by a period in which the plant is not running steadily, with parameters excursioning, alarms flooding, interlocks bypassed and operators intervening manually, and the instability itself is therefore a leading indicator that can be managed. The standard sets the management framework: the definition and scope of process stability, the responsibilities and organisation, the identification of the critical process parameters and their stable operating envelopes, the monitoring and the indicators including alarm rates, operator interventions, parameter excursions and interlock bypasses, the analysis of instability and its causes, the control and improvement measures, the management of change and of temporary operation, the training and the assessment, and the continuous improvement cycle. It takes effect on 1 April 2025.

This document specifies the general principles, leadership, planning, support, operation process control, performance management, and other aspects of process stability management for hazardous chemical production enterprises. Management requirements for process stability management elements such as efficiency evaluation and improvement. This document applies to process stability management of hazardous chemical production enterprises.

Note. In order to avoid confusion, the "hazardous chemical production enterprises" in this document are hereinafter referred to as "enterprises".
