Industrial buyers need calcium hydroxide that performs consistently in demanding process environments, supports accurate dosing, and remains stable throughout storage and transportation. Tianjin Huineng Environmental Protection Technology Co., Ltd. supplies high-specific-surface and high-end calcium hydroxide for international customers in emissions control, water treatment, steel, coking, glass, waste-to-energy, and calcium-based materials applications.
With mature production processes, dedicated technical capabilities, and experience in industrial environmental protection, Huineng provides more than a standard hydrated lime powder. Its product portfolio is designed for customers who require dependable reactivity, controlled particle size, low heavy metal content, and compatibility with automated handling systems.
High-Specific-Surface Calcium Hydroxide for Efficient Gas Treatment
Huineng's high-specific-surface calcium hydroxide is produced from high-activity quicklime and customized composite active additives. Process parameters are precisely controlled to support a porous, reactive powder structure. This design helps the material contact acidic components in flue gas more effectively and makes it suitable for dry flue gas desulfurization and related industrial emission control processes.
The product is available in First Grade and Superior Grade specifications. First Grade offers calcium hydroxide purity of at least 90%, a specific surface area of at least 45 square meters per gram, pore volume of at least 0.20 cubic centimeters per gram, heavy metal content of no more than 10 milligrams per kilogram, and a 325 mesh sieve rate of 90%. Superior Grade provides at least 95% purity, at least 55 square meters per gram specific surface area, at least 0.25 cubic centimeters per gram pore volume, heavy metal content no higher than 10 milligrams per kilogram, and a 325 mesh sieve rate of 95%. Drying loss is controlled at no more than 1% for both grades.
This material can be used as a substitute for sodium bicarbonate in dry desulfurization systems. Its operating temperature range for dry desulfurization extends from ambient temperature up to 500 degrees Celsius, allowing application across different furnace, boiler, kiln, and process gas conditions. The resulting desulfurized ash is calcium-based solid waste and may be suitable for resource recovery, subject to the user's process and local regulatory requirements.
Stable Calcium Hydroxide for Water Treatment and Manufacturing
Huineng also supplies high-end calcium hydroxide for water treatment and calcium-based material production. The product is designed for stable performance in automated dosing systems used in municipal and industrial water treatment. Its low heavy metal content supports applications where raw material control and treated-water quality are important purchasing considerations.
High-end calcium hydroxide is offered with calcium hydroxide purity of at least 90% for First Class and at least 95% for Superior Grade. Both grades specify heavy metal content of no more than 10 milligrams per kilogram and a 325 mesh sieve rate of 90% and 95%, respectively. Drying loss is limited to no more than 0.5%, while whiteness is specified at 90 for First Class and 92 for Superior Grade.
Beyond water treatment, this grade can be used as a raw material for calcium stearate and petroleum lubricants. The controlled powder characteristics provide purchasing flexibility for chemical manufacturers and industrial users seeking a dependable calcium source with repeatable handling behavior.
Packaging Designed for Long-Distance Supply
For overseas buyers and distributors, packaging integrity is a practical part of product performance. Huineng provides moisture-resistant packaging options in 25 kilogram, 50 kilogram, 750 kilogram, and 1,000 kilogram woven bags with polyethylene inner bags. This configuration is intended to reduce moisture exposure and help prevent caking during long-distance sea transportation.
The supplied product images show white calcium hydroxide powder in bulk bags, smaller packaged bags, and presentation samples. The bulk packaging format is suitable for warehouse handling, forklift operations, and industrial dosing logistics. Final packaging selection can be discussed according to order quantity, application requirements, and the buyer's distribution or production system.
Proven Applications Across Process Industries
Huineng's calcium hydroxide products have been applied in several demanding industrial scenarios. Reported application references include 4,500 blast furnace hot stove desulfurization at Baowu Steel Shaogang Co., Ltd., dry coke quenching desulfurization at Shougang Jingtang Iron and Steel Co., Ltd., and dry desulfurization combined with SCR denitrification at Shandong Taishan Shenglvyuan Glass Co., Ltd. In the waste-to-energy sector, the product has been used for acid removal in a 350 tons per day boiler at Tianjin Quantai Domestic Waste Treatment Co., Ltd.
Additional application references include electroplating wastewater treatment at Tianjin Liqun Investment Co., Ltd. and industrial wastewater treatment at Chengde Jianlong Special Steel Co., Ltd. These examples demonstrate the material's relevance to steel, coking, glass, waste-to-energy, chemical, and industrial water treatment operations.
