Digital Sulfuric Acid DCS

The design principle of digital sulfuric acid DCS system is to follow the human-machine friendly, avoid people's memory limitations, in line with thinking logic thinking design. Digital sulfuric acid DCS system uses three-layer structure technology to automatically find problems, assist in analyzing problems, and quickly deal with problems. Realize automatic operation of the device and assist the operator to adjust the operating parameters quickly in the initial fault stage of the device. The digital sulfuric acid DCS system uses the technology of situation sensing, electronic operation procedure and error prevention. Use situation perception technology to assist operators to think, electronic operating procedures to prevent misoperation, to prevent safety accidents. Comprehensively improve the economic efficiency of sulfuric acid plant.

Digital Sulfuric Acid Value

With the popularization of digital technology application, sulfuric acid plant with The Times, the new sulfuric acid plant DCS control system has become a standard configuration, the production control of sulfuric acid plant, in order to improve the safety, environmental protection and economy of sulfuric acid plant. However, the reason for the reduction of safety, environmental protection and economy of the sulfuric acid plant is caused by the abnormal state of the sulfuric acid plant. American ASM (Abnormal State Management Association) research, chemical equipment caused by the abnormal state of 36% is caused by equipment failure, 22% is caused by the process, 42% is caused by operator error, reducing operator error or eliminate operator error, will greatly improve the safety, environmental protection and economy of sulfuric acid equipment. According to the ASM Association research results can. Reduce operator errors with a digital sulphuric acid DCS system, and detect process faults in time to reduce abnormal plant conditions by 64%. The digital sulfuric acid DCS system has a friendly human-machine interface, long-term vision, sensory memory, reliable alarm management, operation optimization, to provide start-stop permits, troubleshooting guidance (electronic operation manual). The digital sulfuric acid DCS system is no longer as simple as the PID flow chart into the DCS system, but the integrated sulfuric acid plant overview picture, PFD (process key parameters), PID (automatic control), efficient alarm management and electronic operating manual. The overview screen provides investors, managers and operators with sulfuric acid plant operation KPI (Key performance indicator), PFD managers, engineers and operators with sulfuric acid plant operation health status, and embed alarm management into the PFD. Automatic operation of the unit PID provides the operator with process control of each section of the sulfuric acid plant, and the electronic operating manual and misplaced measures are implanted into the PID.

Digital Sulfuric Acid DCS System

The digital sulfuric acid DCS system is to informationize the sulfuric acid device operating data, presented in front of the operator is the sulfuric acid device operating information, rather than operating data, no longer like the traditional DCS system operator also needs to informationize the operating data. And accurately and quickly present the information of the sulfuric acid device in front of the operator, and guide the operator to process the information. Therefore, the digital sulfuric acid DCS system is designed according to the operator's thinking process, and the operator's thinking mode in the operation process is to find problems, understand problems, and deal with problems. The design follows the logical principle of the operator's thinking on the process and equipment, so as to achieve fast and accurate operation without too much thinking. The operator thought process is shown in Figure 2. To reduce operator thinking, the digital sulfuric acid DCS system incorporates technology to address human short-term memory limitations. By using sensory memory technology, the operator can distinguish the operation information of the device effectively and intervene the device accurately through intuitive state perception technology. Improve the efficiency and safety of plant operation.

Overview Screen

The sulfuric acid device is displayed by a comprehensive view screen, through which the health status of the sulfuric acid device can be fully understood. The comprehensive view screen information is composed of KPI data. In order to reflect the simplicity of the overview screen, the overview screen uses an instrument panel style to distinguish between different types of data, so that the operator does not have to convert in the brain at a glance.

PFD Screen

The sulfur acid making device is displayed by the gas acid PFD and the soda water PFD. The PFD screen is mainly for the operator to quickly analyze and understand the problem. Therefore, the PFD screen not only displays the control point and measurement data, but more importantly, uses the DCS computing power and the correlation between the measurement data. Some virtual instruments are designed in the DCS background program to accurately judge the fault logic of the device, provide the cause of the problem directly to the operator on the screen, and put the problem processing process on the PFD screen to guide the operator to operate.

Digital Sulfuric Acid DCS System Advantage

provides a set of human-machine friendly control system for the operator, integrated sulfuric acid plant production, management, control logic clear and fast operation of the new sulfuric acid plant control system, the application of new technologies such as state sensing, electronic procedures, error prevention and efficient alarm to change the traditional DCS system only PID process control function. The digital sulfuric acid DCS system makes full use of the computing power of DCS system, and programs the traditional work that relies on manual processing, and realizes the standard program of operation experience. The application of digital sulfuric acid DCS system of sulfuric acid device device abnormal state reduced by 64%, economy increased by at least 5%, operation error rate decreased by 90%, assist safety control to reduce 99% of the device start-stop start-stop accidents.
