In order to achieve the country's goal of reducing carbon emissions from GDP, the China Petroleum and Chemical Industry Association is working on an industry-wide guideline. “We call it the 'low-carbon economic roadmap for the petrochemical industry'.†The person told the China Securities Journal reporter that “Now the association is still doing preliminary research and will be issued as a guideline later.â€
Eliminating backward thresholds will increase
On November 26, China officially announced that its CO2 emissions per unit of GDP by 2020 would be 40% to 45% lower than in 2005. The China Securities Journal reporter was informed that the “Low-carbon Economic Road Map†planned by the Petrochemical Association may be mainly requested from the aspects of encouraging technological progress and eliminating backward production capacity.
The relevant personage of the association said: “We will encourage some technological developments that are conducive to reducing carbon emissions, such as reducing raw material consumption, reducing energy consumption, reducing pollutants and carbon dioxide emissions, etc.â€
The petrochemical industry is an industry with a relatively large resource and energy consumption. Coal, petroleum, and natural gas are both necessary for the development of the industry and an indispensable raw material for production. At present, the petrochemical industry has high dependence on resources and energy, with crude oil approaching 50%, potassium chloride exceeding 50%, natural rubber exceeding 75%, and sulfur up to 90%.
In the "Guidelines for Structural Adjustment of the Petroleum and Chemical Industry" previously drafted, the Association has proposed the goal of energy-saving and emission-reduction across the industry: By 2015, the entire industry will ensure the completion of the national "Twelfth Five-Year Plan" energy-saving and emission reduction targets. The comprehensive energy consumption of calcium carbide unit products has dropped to 1 ton of standard coal, yellow phosphorus has dropped to 7 tons of standard coal, and synthetic ammonia has dropped to 1.7 tons of standard coal. Compared to the end of the 11th Five-Year Plan period, COD emissions have dropped by 8%, and ammonia nitrogen emissions have decreased. 15%, sulfur dioxide emissions in the process decreased by 5%.
“The situation in the industry is changing, and the 'low-carbon economy roadmap' may have higher requirements for energy saving and consumption reduction, and the threshold for eliminating backward production capacity may be higher than the “Guidance Opinionâ€,†the source said.
Heavy development "multiple production"
"In the existing technology, we will focus on encouraging the development of polygeneration of coal chemical industry," said the association's source.
He said that the large-scale polygeneration system can combine the power generation, coking and downstream chemical industries in the upper reaches of the industrial chain, and recycle the waste heat generated from power generation, waste gas generated from power generation, tail gas from coking, coal tar and other resources from chemical companies, as raw materials. use. If we combine the petrochemical and coal chemical industry, we may have better emission reduction and higher economic benefits. However, he also pointed out: "The problem of polygeneration is the need for coordination among multiple departments. If it can be coordinated, the benefits may even be 1+1>4."
Liu Yanwei, deputy chief engineer of the Institute of Petroleum and Chemical Industry Planning, told the China Securities Journal that the current main research on carbon emission reduction is based on the recycling and storage of carbon dioxide, whether carbon capture and storage (CCS) or clean coal power generation (IGCC). ) In the country's initial stage, the cost is very high. "If we can increase the structure and pressure scale from the source and increase the added value of follow-up products, it is a relatively realistic way to achieve carbon reduction."
Poly-generation as a strategic direction for the development of clean coal technology refers to the acquisition of a variety of clean secondary energy sources such as electricity, liquid fuels, hydrogen and other gaseous fuels and various high- Value of chemical by-products. According to reports, if the power generation industry adopts a polygeneration system, the power generation efficiency will increase by approximately 10%, and the cost will decrease by 30%. The polygeneration system can also significantly reduce the production costs of chemical products. For example, the cost of producing methanol will be reduced by 40%.
