ATI Group Appears at the 25th Annual Conference of China Adhesive and Tape Industry

In order to strengthen the exchange and cooperation of the industrial chain, promote the reform of the adhesive and adhesive tape industry, and promote the sustainable, innovative and high-quality development of the industry, the 25th China Adhesive and Adhesive Tape Industry Annual Conference was grandly opened in Changzhou, Jiangsu Province from September 8 to 9, 2022. With the theme of "accelerating industrial transformation and upgrading, promoting green and low-carbon development", the conference attracted nearly 900 participants from domestic and foreign manufacturers, engineers and technicians, raw material suppliers, distributors, equipment manufacturers, and experts and scholars from the adhesive, sealant and adhesive tape industries.

Dr. Mao Xiulin, General Manager of Wuxi ATI Group Technology Co., Ltd., was invited to attend the meeting as an expert in the industry, and made a speech on the site of VOCs organic waste gas treatment in the coating and adhesive industries.

Volatiles of adhesives are mainly benzene series, aldehydes, alcohols, styrene and other components, which can be applied to printing products, coated paper, plastic film and other industries. Because the ethyl acetate contained therein is a flammable component, VOC waste gas emissions during the production of adhesives are high, which will have a very important adverse impact on the surrounding environment. If the waste gas is not properly treated, it will also affect the health of employees and the normal life and social ecological environment of nearby residents. Therefore, waste gas from viscose products must be treated to meet the discharge standard.

The waste gas entering RTO consists of ethyl acetate and ethyl lactate, without other trace elements. This part of the composition is organic, free of trace elements such as N and P, and free of benzene, toluene, xylene and other substances. The burner uses natural gas or the solvent specified by the customer as the fuel.
To sum up, the RTO outlet needs to monitor non methane total hydrocarbons and nitrogen oxides. According to the analysis of inlet concentration and removal rate (99%), the total non methane hydrocarbon is less than 30mg/m ³， 50mg/m lower than environmental requirements ³。 For the emission of nitrogen oxides, according to the EIA document, the emission of nitrogen oxides does not need to be converted. According to more than 2000 projects completed in the United States and more than 300 RTO projects completed in China, the emission of nitrogen oxides is far below the emission standard.
The burner system adopts gas-liquid dual purpose burner, which is divided into three groups of pipelines, natural gas ignition pipeline, natural gas main pipeline and carbitol solution pipeline. Natural gas shall be used during normal startup and temperature rise. After the temperature exceeds 800 ℃, switch to the solvent pipe designated by the customer to consume the solvent designated by the customer.
