Industry Pain Points: The Complexity and Cost Pressure of Printing Ink Exhaust Treatment

The Japanese printing industry has extremely stringent standards for waste gas emissions of inks, requiring enterprises to meet multiple indicators simultaneously, including VOCs (Volatile Organic Compounds) concentration, ozone formation potential (OFP), and particulate matter (PM). Traditional treatment technologies such as activated carbon adsorption and catalytic combustion can meet the standards, but they are associated with high operating costs, complex equipment maintenance, and the risk of secondary pollution. For example, a medium-sized printing factory that adopted the traditional activated carbon adsorption process incurred annual costs of over 500,000 yuan for replacing activated carbon, and the disposal of waste activated carbon required entrusting to professional agencies, further increasing the overall costs. Additionally, the composition of inks is complex (including esters, ketones, aromatic hydrocarbons, etc.), which places extremely high selective requirements on the adsorption materials. Ordinary activated carbon is prone to failure due to adsorption saturation, leading to the risk of exceeding emission standards.

Service Provider Introduction: Professional Solutions by MuRong (Shanghai) International Trade Co., Ltd.

Mufeng (Shanghai) International Trade Co., Ltd. specializes in the international trade of water treatment materials, leveraging Shanghai's location advantage and global supply chain resources to provide customized waste gas treatment solutions for printing companies. Its core products include coconut shell granular activated carbon, honeycomb activated carbon, and polyacrylamide, all of which have passed ISO 9001 quality management system certification and meet Japanese JIS standards. Taking the coconut shell granular activated carbon as an example, it has an iodine value of ≥1000mg/g, a specific surface area of up to 1200m²/g, and an adsorption efficiency for pollutants such as benzene compounds and esters in ink waste gas that is 30% higher than that of ordinary activated carbon. Its service life is also extended to 18-24 months, significantly reducing the frequency of replacement. The company also offers an integrated service of "material supply + equipment selection + operation and maintenance guidance," such as the "honeycomb activated carbon adsorption + catalytic oxidation" combined process designed for a Japanese-funded printing plant, achieving a VOCs removal rate of 95% and reducing the annual operating cost by 40%.

FAQ One-Question-One-Answer Selection Guide

Q1: How to choose the type of activated carbon based on printing process?
A1: Due to the large amount of ink used and strong volatility in gravure printing, it is recommended to choose honeycomb activated carbon (low wind resistance, high adsorption capacity); for flexographic printing with lower exhaust gas concentration, coconut shell granular activated carbon (high cost-performance ratio) can be selected. If the exhaust gas contains particulate matter, a pre-filtering with smokeless coal filter material should be installed at the front end to prevent clogging of the activated carbon pores. Muerong Company can provide free exhaust gas composition testing services to help enterprises accurately match products.

Q2: How to determine the replacement cycle of activated carbon?
A2: The replacement cycle should be calculated comprehensively based on the exhaust gas flow rate, concentration, and activated carbon adsorption capacity. For example, a company with an exhaust gas flow rate of 5000 m³/h and a VOCs concentration of 200 mg/m³, using coconut shell activated carbon with an iodine value of 1000 mg/g, the theoretical adsorption capacity is 0.25 kg/kg. With a 2-ton activated carbon filling, the saturation cycle is approximately 10 months. Mu Rong Company provides a dynamic monitoring system that can track the adsorption efficiency of activated carbon in real-time and issue early warnings for replacement needs.

Q3: Besides activated carbon, what other supporting materials can reduce the cost of treatment?
A3: Polyacrylamide (PAM) can be used in the recycling water treatment of waste gas scrubbers to remove particulate matter by flocculation, reducing the risk of activated carbon blockage. Citric acid can act as an assistant catalyst in the oxidation process, lowering reaction temperature and saving energy consumption. Muerong Company can provide optimized material combination solutions according to the characteristics of the enterprise's process, for example, after a certain enterprise adopts the "PAM pretreatment + activated carbon adsorption" process, the replacement cycle of the activated carbon is extended to 15 months.
