Shanghai Prime Metallurgical Technology Group Co., Ltd. (hereinafter referred to as Prime Group) is a group company integrating technical consultation and service, general contracting of engineering projects, and production and processing of environmental protection materials;
It is a high-tech enterprise in Shanghai mainly focusing on metallurgical engineering, industrial furnace engineering,
and environmental protection engineering.
Prime Group has a complete professional design team for reheating furnace technology, smelting technology,environmental protection technology, mechanical equipment, three-electric automation, vaporization cooling,hydraulic lubrication, water supply and drainage, HVAC, and civil engineering;It has professional procurement with rich experience and strict construction management system; and it also has a perfect after-sales service team.
The Industrial Furnace Division, Smelting Division and Environmental Protection Division are closely connected and coordinated to
achieve a true combination of process + environmental protection, which can better ensure the production effect and index emissions.
In particular, its own processing plant is combined with the environmental protection business department to undertake the research and development and production of materials in the field of environmental protection, and can provide high-quality desulfurizers, calcium-based
ultrafine powders, denitrification agents, catalysts, etc.
In particular, its own processing plant is combined with the environmental protection business division to undertake the research and development and production of materials in the field of environmental protection, and can provide high-quality desulfurizers, calcium-based ultrafine powders, denitrification agents, catalysts, etc.;
In the field of furnaces and kilns, we can undertake various types of slab/rod reheating furnaces, walking beam/pusher type reheating furnaces, regenerative combustion/conventional combustion reheating furnaces, or heat treatment furnaces of various steel pipes/round bars, etc.;
In terms of energy conservation and environmental protection, we have covered the technical services and project general contracting of the whole process of iron and steel enterprises from ironmaking, steelmaking, reheating furnace to steel rolling, including blast furnace gas pressure equalization recovery, off-air ventilation recovery, zero emission; blast furnace gas source fine desulfurization, slag roasting/rolling mill/sintering wet dedusting, heating furnace gas backflush, furnace flue gas desulfurization, dust removal and denitrification, furnace fixed bed dry desulfurization, furnace fixed bed dry desulfurization and denitrification integrated, calcium-based ultrafine powder dry desulfurization (replacing baking soda), etc.;
Based on its own technological accumulation and platform advantages, Shanghai Prime Group has established strategic partnerships with Shougang Group, Baosteel, and some national-level design institutes. Based on these partnerships, our company is capable of undertaking comprehensive flue gas treatment projects and businesses in various industries and civil sectors, including but not limited to coke oven gas treatment (dry quenching, coke oven gas), ceramics, cement, construction materials, and civil applications such as heating. Prime Group offers comprehensive services and project management for various forms of flue gas treatment processes, including desulfurization, dust removal, and denitrification. It also specializes in various new process forms, including but not limited to dust and nitrogen integration (ceramic filter cartridges) and fixed bed dry desulfurization and denitrification integration.
Desulfurization agent and denitrification agent production base:
Jiangsu Xuanding New Material Co., Ltd. is a subsidiary company (joint venture) of Prime Group. It is a research and development, production and sales company for new materials for environmental protection, mainly focus on product development and production in the fields of desulfurization agent, ammonia-free denitrification agent, calcium-based ultrafine powder (replacing baking soda), flue gas denitrification catalyst and other fields.
In order to better meet the needs of customers, especially the short-term demand for high-volume desulfurizers and other environmental protection materials, Prime Group has established production and processing bases for environmental protection materials in Jiangsu Hai'an, Anhui Tongling, Anhui Chizhou, and other places, which can achieve an annual production capacity of 20,000 tons;
Relying on Prime Group and its own scientific research team, each material production base provides comprehensive process solutions to end-users for various working conditions. Combined with the process route, we provide users with targeted special materials, in order to achieve user environmental protection standards and achieve the most optimal investment and operating costs.
Based on the above, Prime Group can also provide the following services:
1)Based on the close combination of our own furnace and environmental protection business division, we can provide fixed-bed dry desulfurization and calcium-based dry desulfurization project general contracting services;
2)Relying on the synergistic cooperation of several processing bases under the Group, we can provide desulfurizers, ammonia-free denitrification agent, calcium-based ultrafine powder(replacing baking soda), and flue gas denitrification catalyst material supply service;
3)We provide corresponding technical consultation and transformation services to the client's existing projects so as to help steel companies meet emission standards;
Shanghai Prime, as an engineering and technology company, also has an environmental materials production and processing base, which enables a close integration and complementarity between engineering projects and core materials production.
Based on this, we can simultaneously provide the following services:
Supply of environmentally friendly materials.
Integrated services such as operation and maintenance(if needed)
Recovery of calcium-based desulfurization byproducts
Assisting the client in achieving closed-loop recycling and comprehensive utilization of by-products.
By-products can be further utilized and formed into a closed-loop recycling system.
The by-products, which are calcium-based, primarily consist of Ca(OH)2. With calcium sulfate (gypsum) as the main component of the final by-product, it can be utilized in subsequent processes such as brick making and cement plants. It can also serve as a raw material for wet flue gas desulfurization, forming a "closed-loop recycling of by-products" (as mentioned in note 1).
Note 1:
Closed-loop recycling of by-products refers to the application of calcium-based desulfurization by-products in alkaline liquid preparation, such as wet flue gas desulfurization, to form a self-contained closed-loop recycling system.
Calcium-based ultrafine powder
Calcium-based ultrafine powder is a high-surface area powder composed of calcium hydroxide. It differs from traditional micron-sized calcium hydroxide and is a nanometer/submicron-sized powder with high surface area and high interfacial reactivity. This product is characterized by its larger specific surface area, well-developed porosity, and smaller particle size.
Compared to regular calcium hydroxide, high-surface area calcium hydroxide has slightly smaller geometric dimensions. The particle morphology transforms from compact clusters into porous and irregular shapes. The interface changes from relatively smooth plates or steps to a rough and irregular interface with scattered protrusions. The fine microstructure of the particles becomes more complex, resulting in increased roughness, and the specific surface area multiplies accordingly.
From another perspective, the surface characteristics of high-surface area calcium hydroxide can be reflected in terms of average particle size being smaller and having a narrower particle size distribution. The majority of particles are smaller than 30 μm, accounting for 99% of the total cumulative volume. Furthermore, more than 70% of the particles have medium to small pore sizes below 20 nm. In contrast, regular calcium hydroxide is primarily composed of larger pores above 40 nm. This difference in pore sizes is the root cause of variations in BET specific surface area, pore volume, and adsorption performance towards acidic gases.
Specifications for calcium-based ultrafine powder:
Purity: 90% .
Particle size (D50, scanning electron microscopy) ≤18 micrometers, corresponding to a mesh size of 800 or above.
Specific surface area (BET): ≥35 m²/g.
Moisture content: ≤2%.
