Redsun's analysis of the energy-saving and carbon-reduction benefits of empowering petrochemical enterprises across the entire industrial chain
2025-07-23
Tianjin Redsun Science and Technology Development Group Co., Ltd. (hereinafter referred to as "Redsun Group") is a comprehensive high-tech enterprise integrating intelligent environmental protection and biomass new energy industries. Since its establishment in 2002, it has invested 1 billion yuan, building a 40,000 t/d domestic sewage treatment plant, a 20,000 t/d industrial sewage treatment plant, a 30,000 t/d pure water plant, a 400 t/d organic solid waste resource utilization plant, a 100 million-plant reed rhizome tissue culture base, a 200,000 t/a biomass fuel processing plant, a functional chemical production base, and an environmental monitoring center. Relying on the deep layout of the entire industrial chain, it has successfully created the country's only green zero-carbon circular economy demonstration model, forming a full-chain carbon-neutral solution covering planning, design, investment, and operation, providing technical support for petrochemical enterprises to move towards zero carbon.
I. Biomass Energy Replacing Fossil Energy
Currently, carbon emissions from the petrochemical industry mainly come from fossil fuel combustion, industrial production processes, and the purchase of electricity and heat. Data shows that fuel combustion and electricity and heat supply during the production process account for 66.1% of the carbon emissions from petrochemical production, and the industrial production process accounts for 3.9%, making the green transformation of energy for petrochemical enterprises a top priority. As early as June 2022, Redsun Group launched scientific research cooperation with Tianjin Petrochemical on biomass fuel co-firing, testing co-firing ratios of 10% and 20% biomass pellets. Experimental results show that the 465 t/h ultra-high-pressure circulating fluidized bed boiler (CFB) in the thermal power department can operate stably at a 20% biomass pellet co-firing ratio. Subsequently, Redsun Group pioneered the "three stable and one guaranteed" (stable output, stable quality, stable cost, and guaranteed supply) biomass fuel supply system, promising to provide petrochemical enterprises with sufficient and stable biomass fuel.
Taking Tianjin Petrochemical as an example, from August 2023 to February of the following year, the company supplied a total of 20,000 tons of biomass pellets, with a co-firing ratio fluctuating between 5% and 20%. During use, the circulating fluidized bed boiler operated smoothly, and environmental protection indicators were qualified and met standards. The entire process reduced carbon dioxide emissions by 28,800 tons, reduced sulfur dioxide emissions by 16 kg, and saved costs of 56,000 yuan based on the amount of limestone used in the plant. Taking this as an opportunity, Redsun Group is serving petrochemical enterprises such as Dagang Power Plant and Yangliuqing Power Plant to build biomass coal co-firing projects, continuously expanding its achievements. For the fuel needs of petrochemical enterprises outside the region, Redsun Group can invest in the construction of plants to provide supporting supplies. Within a radius of 200 kilometers around 1-2 petrochemical enterprises, a 500,000-ton/year biomass pellet processing plant needs to be built to achieve stable supply. After full production, it can replace 350,000 tons of power coal annually, reducing carbon dioxide emissions by 665,000 tons and sulfur dioxide emissions by 4,000 tons, resulting in carbon benefits of 52 million yuan. At the same time, it reduces the amount of desulfurization raw materials by 57%, reduces ash slag production, and greatly reduces disposal pressure and costs.
II. Reed Planting Replacing Coal to Achieve Carbon Reduction Goals
"Green Island No. 1" polyploid reed is a highly efficient energy plant. The dry matter yield of reed can reach more than 4 tons per mu, with a calorific value of 3800-4400 kcal/kg, 800 kcal/kg higher than the average of other straws, superior to most agricultural raw materials, and has advantages such as strong resistance, soil improvement, and soil and water conservation. According to calculations, each link in the reed seedling cultivation-planting-processing-utilization industrial chain can produce corresponding carbon emission reductions. For every ton of dry reed produced, an average of 0.3 tons of organic fertilizer is consumed, producing 1 ton of biomass fuel, which in turn produces 0.4 tons of green methanol or replaces the combustion of 0.57 tons of standard coal. Based on last year's highest carbon market price (i.e., 100-110 yuan/ton carbon emission rights price), the use of dry reed per ton instead of coal can create carbon sink income exceeding 304 yuan.
Redsun Group plans to cultivate 20 million mu of reed by 2032, generating nearly 10 billion yuan in annual carbon sink revenue. A stable supply system will be ensured through the targeted delivery of reed biomass fuel, supporting the "three stable and one guaranteed" policy. Carbon offsetting from reed carbon sinks will contribute to the company's zero-carbon goals. Based on a 15,000-mu demonstration project focused on improved reed cultivation, Redsun Group, through full-chain technological empowerment and standardized management, commits to supplying petrochemical companies with reed at a dry-matter price of no more than 400 yuan per ton, establishing a long-term stable market price.
III. Functional Chemical Supply
Redsun Group's subsidiary, Ruide Sain New Materials Co., Ltd., established in 2007, is an innovative enterprise focusing on the production and sales of coal chemical auxiliaries, petroleum chemical auxiliaries, and water treatment agents. The company has developed more than 100 products, including ethylene refining agents, coal chemical agents, and water treatment agents, covering various aspects of petrochemical equipment, from reaction catalysis to product refining and pollutant treatment. All of them have the functions of ensuring smooth operation of equipment, extending service life, and energy saving and carbon reduction.
