The application fields of highly active calcium hydroxide desulfurizers continue to expand, and the market development prospects are promising

Highly active calcium hydroxide desulfurizer is a high-efficiency calcium-based desulfurizer. Compared with ordinary calcium-based desulfurizers, high-activity calcium hydroxide desulfurizer has the advantages of high desulfurization efficiency, large specific surface area, and high activity. Compared with sodium-based desulfurizers, Desulfurizer, highly active calcium hydroxide desulfurizer solves the problem of ineffective utilization of sodium-based desulfurization ash and hidden dangers of secondary pollution. Against the background of increasingly stringent environmental protection supervision and the gradual advancement of air pollution prevention and control actions, the market for highly active calcium hydroxide desulfurizers has broad room for development.

According to the “2021-2026 China Highly Active Calcium Hydroxide Desulfurizer Industry Market In-depth Research and Development Prospects Forecast Report》shows that the representative manufacturer of high-activity calcium hydroxide desulfurizers in my country is Beijing Yuzhi Environmental Protection Technology Co., Ltd. As a pioneer, Beijing Yuzhi Environmental Protection Technology has filled the gap in the domestic market of high-specific surface area, high-activity calcium hydroxide desulfurizers. Beijing Yuzhi Environmental Protection Technology has a 100,000-ton/year high-activity calcium hydroxide production device located in Anyang, Henan.

In 2021, with the active layout of enterprises, the market promotion and application of highly active calcium hydroxide desulfurizers will accelerate, and the downstream application fields will gradually expand to coking, steel, glass, lime, ceramics, refractory materials and other fields. At the same time, in order to achieve product standardization and standardized production, Beijing Yuzhi Environmental Protection Technology compiled the enterprise standard “Highly Active Calcium Hydroxide Desulfurizer” (Q/YZKJ1 0101-2021) and announced it to the public on October 26, 2021.

According to different raw materials, desulfurizers can be divided into sodium-based desulfurizers, calcium-based desulfurizers, etc., among which sodium-based desulfurizers are the mainstream products. Dry desulfurization technology (SDS for short) uses the sodium-based desulfurization agent sodium bicarbonate as an alkali source desulfurization technology. It has the advantages of high desulfurization efficiency, wide sources of desulfurization agents, and low cost. In recent years, with its advantages, dry desulfurization technology The application fields are gradually expanding, and its application proportion in the coking industry is close to 40%. However, as the number of equipment increases, the problem of difficulty in processing sodium-based desulfurization ash appears.

Sodium-based desulfurization ash is a mixture of sodium sulfate, sodium sulfite, and sodium carbonate. It is a general solid waste that is difficult to dispose of in compliance with regulations. In 2020, the output of my country’s coking industry will be close to 420 million tons, and the annual output of sodium-based desulfurization ash corresponding to the coking industry alone will reach About 280,000 tons. Against the background of increasingly stringent environmental protection regulations, the need for reasonable treatment of sodium-based desulfurization ash has become increasingly urgent, and the market demand for high-performance desulfurizers continues to be released, providing a broad space for the development of the highly active calcium hydroxide desulfurizer market.

Industry analysts said that as a high-efficiency desulfurizer, highly active calcium hydroxide desulfurizer has the advantages of high desulfurization efficiency and large specific surface area. , its large-scale application can help solve the problem of sodium-based desulfurization by-product disposal and promote the environmentally friendly and sustainable development of coking, steel and other industries. Driven by the increasingly strict environmental protection supervision and the active layout of relevant enterprises, the market for high-activity calcium hydroxide desulfurizers has broad development space.
