The Ministry of Ecology and Environment issued a notice on July 27 to carry out pilot work on environmental impact assessment of carbon emissions from construction projects in key industries. According to the notice, by the end of June 2022, the carbon emission level and emission reduction potential of key industries will be basically figured out, and technical methods will be explored to form the coordinated management and control evaluation of pollutants and carbon emissions of construction projects to achieve the synergy of pollution reduction and carbon emission reduction from the source. The pilot areas and industries are as follows:
Energy conservation and emission reduction is the general trend of society, and it is a huge challenge for the chemical industry. One of the core paths to achieve this goal is technology research and development. Let us see how these companies that have been effective on the road to energy conservation and emission reduction are What do you do?
Ineos Aromatics Zhuhai plant mainly produces PTA, which is the raw material used to manufacture fibers, textiles, films and PET bottle flakes in the polyester industry. The Zhuhai plant took the lead in adopting the latest generation of PTA technology in 2015, significantly reducing carbon emissions and waste. Since the introduction of this technology, the Zhuhai plant has effectively converted the heat generated during the PTA production process into electricity. This not only saves production energy consumption, but also enables the factory to export electricity to the grid. By the beginning of 2021, the factory's total output of electricity to the grid reached 200 million kilowatt-hours, which is equivalent to a reduction of approximately 125,000 tons of carbon dioxide emissions.
Huntsman (Huntsman) has developed a recycling technology for recycled PET plastics. The technology is used to produce TEROL polyester polyols. Up to 60% of its ingredients come from recycled PET plastics, while polyester polyols are used One of the important raw materials for the production of polyurethane materials. This recycling technology is being applied at Huntsman's polyurethane composite material plant in Tianjin. In addition, Huntsman also intends to build an environmentally friendly recycled polyester plant in mainland China.
WACKER’s Nanjing production base adopts a backward integrated polymer production process to integrate all of the company’s polymer production in China into the same production base to achieve synergy in energy consumption and reduce carbon footprint. On this basis, the factory continues to continuously improve the production process, and continues to invest in the transformation and upgrading of existing equipment to further reduce carbon emissions. At the same time, WACKER's Nanjing production base is also upgrading the waste gas incinerator, using waste heat to produce steam. After the project is completed, it is expected to reduce 17,000 tons of carbon emissions each year. In addition, with the long-term implementation of the "WACKER Operating System", the WACKER Nanjing production base is also reducing the unit output consumption of raw materials, energy and water, and the discharge of waste solids, liquids and gases year by year.
Hengli Petrochemical applies embedded wastewater integrated treatment technology to achieve a reclaimed water reuse rate of more than 80%, and the treated wastewater COD is controlled below 20mg/L, which is better than the national standard of 50mg/L. Hengli Petrochemical has also applied the first PTA residue recovery system in the PTA industry-R2R device, which overcomes the problem of PTA residue recovery and treatment, and achieves zero emissions. It can recover nearly 6000 tons of benzoic acid, 1.5 tons of cobalt acetate, and CMB (catalyst ) About 3000 tons.
BASF Ludwig Chemical Park is located on the banks of the Rhine. According to the concept of circular economy, dozens of basic materials are produced from several raw materials in the park, and hundreds of intermediates are produced, which are then used in the value-added chain to produce more than 8,000 Products, and the park is lined with trees, and there is no dripping or dripping. From planning, decision-making, design, construction, operation to management, with rigorous and down-to-earth style, a typical case of green and low-carbon circular development of chemical enterprises has been established.
As one of the six high-energy-consuming industries, the petroleum and chemical industries have generally not got rid of the development mode of high investment, high consumption and high emissions. Energy saving and emission reduction benefit the country and the people, and there is a long way to go. Looking forward to the transformation and development of the industry , Can emerge more new technologies and new paths with high efficiency, energy saving and green environmental protection!
