Amine absorption is the mainstream technology for removing acidic H₂S and CO₂ from natural gas and LPG via recyclable MDEA, DEA and MEA solvents. Long-term operation causes solvent contamination with organic hydrocarbons, oils, degradation products and solids, which conventional filters cannot remove. Such impurities induce severe amine foaming, lowering gas purification efficiency, triggering system instability, solvent loss and high operating costs. Granular activated carbon (GAC) serves as a core side-stream filtration medium for amine systems. With superior adsorption performance, GAC removes dissolved organic pollutants and foaming substances, effectively inhibiting solution fouling and foaming, stabilizing operational performance and extending solvent lifespan. Its purification effect relies on sufficient contact time and proper dosage. For optimal filtration, activated carbon should feature an iodine number over 900 mg/g; coal-based carbon suits large-molecule foam contaminants while coconut shell carbon targets small degradation products, ensuring efficient and stable operation of gas sweetening units.

Complete Guide to Activated Carbon: Definition, Safety, Customs Code, Principles, Applications and Prices This article systematically introduces the core knowledge of activated carbon, covering the following six aspects: Definition Clarification: Activated carbon and activated wood charcoal are the same substance. The terms "medical grade" and "industrial grade" differ but the essence is the same. Safety and Regulations: Safe Operation: Non-toxic but flammable and explosive. Be cautious of dust inhalation and moisture prevention. Customs Coding: Mainly classified under 3802.10.00 (especially coconut shell steam activated carbon). Principles and Applications: Adsorption Principle: Mainly relies on physical adsorption (microporous van der Waals force) and a small amount of chemical adsorption. Main Applications: Covering water purification, air treatment, food decolorization, medicine, catalyst carrier, and defense protection. Market Prices: Significant Price Variability: Coal-based carbon approximately 5,000 - 8,000 yuan/ton, coconut shell carbon 12,000 - 20,000 yuan/ton, and high-end medical grade can reach 25,000 - 45,000 yuan/ton. Key Influencing Factors: Raw materials, iodine value, and particle size. Summary in One Sentence: This article is a comprehensive technical guide on activated carbon, providing clear and practical reference information from basic definitions, safety regulations, customs coding, to core adsorption principles, market applications, and price trends.

Municipal drinking water generally uses chlorine and chloramine as disinfectants to eliminate harmful microorganisms. Chlorine is efficient and low-cost yet unstable, while chloramine features better stability and longer-lasting disinfection effect but is far harder to remove. Their residues cause unpleasant taste and odor, generate harmful disinfection by-products and damage precision water treatment equipment, failing to meet the strict water quality requirements of food, pharmaceutical, electronics and other industries. Coconut shell activated carbon delivers excellent adsorption and catalytic reduction performance to effectively remove residual chlorine and chloramine from water. In particular, catalytic coconut shell activated carbon works remarkably well on chloramine. Boasting high hardness and long service life, it is widely applied in municipal water purification, industrial water treatment, household water filters and aquaculture systems, serving as an efficient and cost-effective solution to eliminate chlorine-based residues, improve water quality and protect water treatment facilities.
Introduction With the acceleration of urbanization, most urban sewage treatment plants are located on the outskirts of cities or densely populated areas. Malodorous gases generated during sewage treatment have become a major air pollutant. These unpleasant odors not only undermine the living quality of nearby residents but also contain harmful substances such as hydrogen sulfide and ammonia, posing potential risks to human health. In recent years, authorities have imposed increasingly stringent requirements on air quality, making odor control at sewage treatment plants a key part of environmental protection work. Against this backdrop, pellet activated carbon specially developed by Yihang for odor control in municipal sewage treatment has played a vital role in addressing this issue thanks to its outstanding adsorption performance. This article elaborates on relevant applications from multiple aspects below.
This article provides a comprehensive overview of 8-30 mesh and 12-40 mesh coconut shell activated carbon, core products in the water treatment industry. It clarifies the industry definition of "mesh", the particle size range and applicable scenarios of the two key specifications, sorts out the main categories and characteristics of water treatment activated carbon, and focuses on the core functions of coconut shell activated carbon in drinking water purification, including heavy metal adsorption, taste optimization and water softening. It also highlights the price trend from 2024 to May 2026: prices remained stable in 2024, continued to rise in 2025, and have surged sharply by May 2026, with a maximum increase of over 140%. The core driving factors of the price surge are analyzed, and professional suggestions on specification selection, cost control and procurement planning are finally provided.
