Dow Powered Low-Carbon Cracking Technology

Recently, Dow Chemical executives stated that the company is advancing more environmentally friendly ethane dehydrogenation (EDH) and electro-cracking (e-cracking) technologies in order to significantly reduce the carbon emissions of existing cracking units, and hope that one day it will be built with low carbon carbon emissions.

According to Dow Chemical's carbon neutral plan, by 2030, the company will reduce its annual net carbon emissions by 5 million tons, which is 15% less than the baseline level in 2020; by 2050, the company will achieve carbon neutrality.

Progress in low-carbon technology

Dow Chemical is using its proprietary technology to develop ethane dehydrogenation, and is evaluating some potential technology suppliers, such as the U.

Dow Chemical Hydrocarbons Global Sustainability Director Manavi Rahorti said: “Dow will demonstrate this propylene production technology next year, while continuing to research ethylene production technology.

Dow Chemical also cooperated with Shell to develop electrolytic cracking technology.

In electric cracking technology, electricity will be used to heat the cracking furnace instead of natural gas.

Lahoti also pointed out: "In the future, Dow Chemical will consider reducing carbon emissions as an important consideration when deciding to build a new cracker.

Play the important role of hydrogen

　　Dow believes that hydrogen can play an important role in the future cracker, not only for heating the cracker, but also for the new process of ethane to produce ethylene.

　　The company believes that the most likely hydrogen used in chemical production in the future is blue hydrogen produced when methane is injected into an autothermal reformer (ATR).

　　In addition, Dow Chemical is also cooperating with Eco Catalysis Technology Company and Southwest Research Institute on "Integration of Hydrogen Combustion and Energy-Saving Ethylene Production".

　　No matter which technical route can be achieved in the future, hydrogen will play a more important role in chemical production in the future.

　　Drive carbon reduction through the value chain

　　Dow Chemical believes that the timing of using low-carbon emission cracking technology depends not only on the development of the technology, but also on the value that customers place on the products produced using these technologies.

　　Stone said: "Our customers are very interested in low-carbon solutions.

　　Dow Chemical is also working on many different technologies and methods to reduce carbon emissions, including blue hydrogen, carbon capture and storage, renewable energy and energy efficiency projects.
