Chemical industry energy-saving emission reduction

The oil and chemical industry is a vital sector that serves as both an energy source and a supplier of raw materials, but it also carries high energy consumption and significant environmental pollution. Among the key energy-consuming enterprises identified by the National Development and Reform Commission, 340 oil and chemical companies account for one-third of the total. Meanwhile, the Ministry of Environmental Protection has listed 482 oil and chemical companies as key polluters for waste gas and wastewater emissions, with 803 more under monitoring—representing 13.4% and 25.8%, respectively. This highlights the critical challenge the industry faces in achieving energy conservation and emission reduction. To meet national targets, the China Petroleum and Chemical Industry Association set specific goals during the "Eleventh Five-Year Plan." These included reducing energy consumption per 10,000 yuan of industrial added value by 15–20% compared to 2005, cutting water usage per unit of industrial added value by 30%, increasing the recycling rate of industrial water to 90%, raising the comprehensive utilization rate of industrial solid waste to 70%, and decreasing the total discharge of major pollutants by 10%. Efforts to implement these goals have already begun. The association introduced six key measures, such as raising awareness about energy efficiency, optimizing industrial structure, promoting circular economy, advancing technological innovation, cultivating specialized talent, and establishing an evaluation system for energy saving and emission reduction. In collaboration with the National Standards Committee, the association also worked on setting energy consumption limits for four high-energy products: ammonia, caustic soda, calcium carbide, and yellow phosphorus. These standards took effect in June this year, raising industry access thresholds and helping to eliminate many heavily polluting enterprises in sectors like nitrogen fertilizers, soda ash, and others. Pollution surveys were conducted in key river basins, and non-compliant wastewater discharge outlets were closed. Clean production initiatives were launched, and mature energy-saving technologies were promoted. As a result, energy consumption growth in the industry was curbed, pollutant emissions decreased, and corporate reputations improved. In 2007, energy consumption for six major products, including crude oil processing, caustic soda, and ethylene, saw reductions of 2.28%, 4.03%, 1.03%, 2.96%, 1.1%, and 4.1%, respectively. In the first quarter of this year, energy use continued to decline, with an average drop of 3.68%, up 1.2 percentage points from 2007. Despite progress, challenges remain. High-energy and high-pollution production capacity continues to grow rapidly, making it harder to control. Basic data collection and statistical methods are still lacking, and the development and application of energy-saving technologies need improvement. Looking ahead, the focus will be on restructuring the industry, reducing high-energy and high-pollution sectors through shutdowns, reorganization, and technological upgrades. Investment in new industries with high technology and low resource use will be encouraged. Strengthening statistical systems, setting clear benchmarks, and promoting practical technologies will also be priorities. Engineering design plays a crucial role in energy efficiency and emission reduction. The petrochemical association now requires that energy-saving concepts be prioritized in all project designs. In October, the association will hold a conference to showcase achievements, share experiences, and display new energy-saving technologies and equipment. Although the chemical industry is inherently polluting, the issue lies in management and approach. With national emphasis on energy conservation and environmental protection, the industry must adapt. Energy-saving and emission reduction are not just regulatory requirements—they are essential for sustainable development and industrial transformation. The domestic chemical sector is actively seeking solutions, recognizing that these efforts are key to its long-term success.

Peephole Drilling Machine

• This type of machine is operated by hand. It is relatively simple in structure and usually consists of a hand-held drill and a guide device. Operators need to manually position the drill and apply force to drill the hole for the peephole. Manual peephole drilling machines are suitable for small-scale operations or occasional use.
• Advantages: Low cost, easy to operate and carry. Disadvantages: Low drilling efficiency, requires a certain level of skill and physical strength from the operator.

• Semi-automatic peephole drilling machines combine manual and mechanical operations. They typically have some automated features such as a motor-driven drill bit and a positioning mechanism. Operators still need to manually place the door or workpiece, but the drilling process is partially automated, which improves drilling accuracy and efficiency compared to manual machines.
• Advantages: Moderate cost, improved efficiency and accuracy compared to manual ones. Disadvantages: Not fully automated, still requires some manual intervention.

• Automatic peephole drilling machines are highly advanced and are designed for large-scale production. They are equipped with computer-controlled systems, automatic feeding mechanisms, and precision drilling heads. These machines can automatically detect the position of the door, adjust the drilling parameters, and complete the drilling process with high speed and accuracy.
• Advantages: High drilling efficiency, precise drilling, suitable for mass production. Disadvantages: Higher cost, complex maintenance requirements, and need professional operators to handle.
