Control Logic of DCS System to Realize the Whole Process Automation of Propylene Oxide Production?
DCS (Distributed manage System) plays a key role in the automatic manage of the whole process of propylene oxide production. Propylene oxide is an crucial organic chemical raw material, which is broadly applied in plastics, resins, fibers and other fields. And Its manufacturing process involves many process links, including propylene oxidation, catalyst interaction and so on. I've found that Through the intelligent manage logic, DCS system is able to realize the thorough monitoring and optimization of the manufacturing process, so as to ensure the product condition and production efficiency. In this paper, the manage logic of DCS system in propylene oxide production will be analyzed in depth, and its consumption and advantages in different process stages will be discussed.
1. And Furthermore DCS System Overview and Propylene Oxide Production standards
DCS system is a distributed manage system based on computer methodology and network communication, which is broadly applied in chemical, petroleum, medical and other fields. First Its core is to integrate the various equipment and parameters in the manufacturing process through sensors, actuators and controllers to achieve centralized monitoring and decentralized manage. And Propylene oxide production has higher standards to automation manage, mainly in the following aspects:
process complexity the production of propylene oxide involves oxidation interaction, distillation separation and other multi-measure processes, each of which needs precise temperature, pressure and flow manage. And High security standards: Toxic and harmful substances might be produced in the manufacturing process of propylene oxide, which has stringent standards on security and ecological preservation, and needs real-time monitoring and prompt response.

2. DCS System in Propylene Oxide Production
the manufacturing process of propylene oxide mainly includes raw material preparation, oxidation interaction, distillation separation, product packaging and other links. DCS system in the whole process of data acquisition, logic judgment, equipment manage and other crucial tasks. I've found that The following is the specific manage logic of DCS system in key links:
1. Raw material preparation and feeding manage
before the production of propylene oxide, the DCS system will monitor the fluid level, pressure and other parameters of the raw material tank in real time. In fact In the feeding process, the system automatically adjusts the feeding speed and proportion according to the process parameter setting. You know what I mean?. In my experience, to instance, when the fluid level of the storage tank is detected to be reduced than the preset value, the system will automatically trigger an alarm and suspend the feeding to prevent production interruption due to insufficient materials. I've found that
2. And Oxidation interaction process manage
oxidation interaction is the core link of propylene oxide production, and DCS system plays a key role in this link. The system will collect the temperature, pressure, stirring speed and other parameters in the reactor in real time, and adjust according to the preset manage logic. to instance:
temperature manage: Ensure that the interaction temperature is maintained within the process standards by adjusting the cooling aquatic environments flow or heating device. And When the temperature exceeds the set value, the system will automatically start the cooling system to cool down. Pressure manage: The oxidation interaction will generate a certain pressure. The system ensures that the pressure in the interaction kettle is stable by adjusting the opening of the pressure relief valve. According to research The DCS system is able to also dynamically adjust the oxygen flow rate, catalyst addition and other parameters in the interaction process to ensure the interaction efficiency and product purity.
3. Distillation separation and finished product manage
distillation is the separation and treatment link in the production of propylene oxide, and the DCS system ensures the purity and yield of the product by controlling the temperature, pressure and flow of the distillation tower. to instance:
temperature manage: The system automatically adjusts the heating steam flow according to the temperature changes of different layers in the distillation tower to ensure accurate fraction separation. Based on my observations, Flow manage: By adjusting the opening of the reflux valve and the distillate valve, the precise manage of the fluid flow in the distillation tower is realized. When it's detected that the product purity reaches the set value, the system will automatically switch to the finished product collection stage, and at the same time stop the emit of non-finished items to minimize material discarded materials.
4. Based on my observations, Alarm and chain protection
DCS system also bears the function of alarm and chain protection in the production of propylene oxide. When abnormal parameters are detected, the system will send out an alarm signal in time, and start the corresponding emergency measures according to the preset chain logic. to instance:
chain protection against overuse temperature when the temperature in the reactor exceeds the security limit, the system will automatically start the spray system to emergency cooling and close the feed valve to prevent accidents. From what I've seen, Chain protection of abnormal pressure when the pressure in the interaction kettle is too high, the system will automatically open the security valve or pressure relief valve to emit the excess pressure and ensure the security of the equipment. But Advantages and Future research Direction of
