Contract signed for the fixed-bed inter-cooling renovation at Dongguang Chemical’s Second Plant (Phase 3); operation to begin by the end of 2020! Author/Source: Shanghai Jingye Environmental Protection Date: 2020-08-21 Clicks: 8 News Update: Contract signed for the cooling system renovation of the fixed-bed reactors at Dongguang Chemical’s Second Plant (Phase 3); operation is set to begin by the end of 2020! In Cangzhou in June, the sun is scorching hot ； Within the gas production workshop area of Hebei Dongguang Chemical Plant No. 1, there was the sound of people and horses, creating a bustling atmosphere. In the first half of 2020, the UGI fixed-bed coal gasification multi-pollutant purification project (Phase II), carried out jointly by Shanghai Jingye Environmental Protection Energy Technology Co., Ltd. (hereinafter referred to as “Shanghai Jingye”) and Hebei Dongguang Chemical Co., Ltd. (hereinafter referred to as “Dongguang Chemical”), was in full progress. The construction of this project is now nearing completion. The gas purification and filtration module GCM has been installed in place, and work is currently underway on the installation and commissioning of the associated process pipelines, electrical systems, and instrumentation. It is expected that the project will be completed as planned by the end of July, ready for operation. I. Contract signed for the inter-cooling renovation project at Dongguang Plant No. 2. Shanghai Jingye Environmental Protection Company has developed a multi-pollutant purification system for coal-to-gas production, tailored for the environmental improvement of fixed-bed processes; this system has received high recognition from industry professionals and environmental protection authorities. It is believed that this system represents the best approach to rapidly reducing the total amount of pollutants under the current challenging circumstances: it requires a short renovation period, involves low investment costs, and enables a significant reduction in the total amount of pollutants ； It also helps to reduce the assessment of indicators such as tons of ammonia per unit of wastewater, exhaust gas, waste residue, and ammonia consumption per ton. It was precisely recognizing this that the decision-makers at Dongguang Chemical acted with foresight, investing substantial funds and showing great courage. With a spirit of being pioneers, they joined forces with Zhengyuan and Shanghai Jingye to carry out comprehensive environmental protection upgrades for all 42 gas generation furnaces in the plant; the completion of these upgrades is expected by the end of November this year. To date, the pilot plant has been operating stably for 7 months, and the pilot-scale samples meet the expected standards; by then, environmental hazards such as gray water, VOCs, and wet slag that affect production will be fully addressed, controlled, and utilized sustainably. II. Further Reading – Multi-pollutant Purification System for Coal-to-Gas Production in Shanghai Jingye (for UGI gas generation) 1. Overview of the main environmental issues associated with traditional UGI gas generation processes 1. The process generates large amounts of wastewater with a complex composition, containing significant quantities of organic and inorganic substances, volatile compounds, as well as toxic and harmful materials; the amount of wastewater produced per ton of ammonia can reach up to 1200 Kg ； 2. There is a large amount of wet slag; the factory area has a poor environment, the value of on-site conversion and utilization is low, and there is a phenomenon of pollutants being transferred to other areas ； 3. The wastewater recycling and cooling processes result in large amounts of VOCs being released into the atmosphere, severely affecting the local environment and worker health ； 4. Current status of environmental protection measures for UGI gas production: According to the survey results, aside from Dongguang Chemical, which has invested significant resources in taking proactive actions to address this issue, several companies in Shanxi province have also contacted our company to pursue similar efforts. 3. Features of the treatment technology: (1) Three system modules integrating patented technologies – the GQCM system (gas upgrading), the GCM system (syngas purification and filtration), and the WPSCM system (purification, treatment, and conversion of process wastewater) – for which Jingye Environmental Protection holds core patent rights. The company is at the forefront in terms of emission standards and control of total emissions. http://img.yf116.cn/image/img/20200821/1024263746682.jpg (2) Short transformation cycle with rapid results: Without altering the existing gas production process or the parameters related to gas composition, taking the transformation of 20 UGI furnaces as an example, the construction time for our company’s multi-pollutant purification system for coal-based gas does not exceed 5 months, and the downtime required for all transformations is no more than 2 weeks. (3) Low consumption, low operating costs
