On the realization of green shutdown of catalytic units

To achieve a green shutdown of the catalytic unit, modifications and actions can be taken in the following areas: 1. Add backup equipment: During the operation of the catalytic unit, backup units can be installed; in the event of a failure or when maintenance is required, these backup units can be activated to ensure that production is not disrupted. 2. Install online monitoring instruments: Install such instruments to monitor the condition of the catalytic unit in real time, detect any abnormalities promptly, and take action to address them, thereby preventing the emission of VOCs. 3. Adoption of cleaning technologies: Cleaning equipment such as activated carbon adsorbers and membrane separators is installed before and after the catalytic units to capture any organic waste gases that may be generated and retain them on their surfaces, thereby reducing the impact on the environment. 4. Strengthen management: Improve management systems, establish comprehensive inspection and maintenance procedures, and carry out regular inspections and maintenance of catalytic units to ensure that the equipment remains in good condition and to reduce the occurrence of failures. At the same time, train the operators to improve their operational skills and reduce the occurrence of human errors. Through the aforementioned modifications and operations, a green shutdown of the catalytic unit can be achieved, thereby avoiding environmental impact. .

Dear Haiyou expert, do you have any valuable insights regarding the environmentally friendly shutdown of catalytic units, especially with regard to the steam purging in the absorption and stabilization systems?

Regarding the environmentally friendly shutdown of catalytic units, which includes the steam purging of the absorption and stabilization system, it can be considered from the following aspects: 1. Before performing steam purging on the absorption and stabilization system, the load on the catalytic unit should be reduced. The catalyst load can be reduced by measures such as lowering the feed temperature, adjusting the catalyst concentration, and reducing the raw material flow rate, thereby decreasing the amount of harmful gases emitted by the catalytic unit. 2. Design a reasonable absorption and stabilization system. During the design and operation of catalytic units, full consideration should be given to the design of the absorption and stabilization system; efficient and energy-saving absorbents should be selected, and their usage amount should be strictly controlled in order to reduce the harmful gases emitted by the system. 3. Install online monitoring devices. During the operation of the absorption and stabilization system, online monitoring devices should be installed to continuously monitor the concentration and composition of the emitted gases, and adjustments should be made promptly to ensure that the catalytic unit does not have an adverse impact on the environment. 4. Implement responsibilities for pollution prevention and control. Enterprises should establish a comprehensive pollution prevention and control system, fulfill their responsibilities in this regard, and carry out regular inspections and maintenance to ensure the proper operation of catalytic units and absorption stabilization systems, thereby avoiding adverse effects on the environment. In summary, through proper design and operational management, as well as enhanced pollution prevention measures, it is possible to achieve environmentally friendly shutdowns of catalytic units, thereby improving the company’s production efficiency and its social reputation. .
