Thread Content

Recently, a tender announcement was issued for the EPC project regarding the upgrade and renovation of the wet desulfurization and denitrification system for coke oven flue gas at Inner Mongolia Hengkun Chemical Co., Ltd. This project mainly involves upgrading the existing wet desulfurization and denitrification systems for coke oven flue gas, and installing a new set of denitrification system for coke oven flue gas that utilizes \"dry desulfurization (columnar calcium-based moving bed) + SCR (with catalysts that are medium- and low-temperature manganese-iron-based denitrification catalysts, which are not hazardous waste)\". Details are as follows: Tender Announcement for the EPC Project of the Upgrade and Renovation of the Wet Desulfurization and Denitrification System for Coke Oven Flue Gas at Inner Mongolia Hengkun Chemical Co., Ltd. 1. Tendering Conditions: The EPC project for the upgrade and renovation of the wet desulfurization and denitrification system for coke oven flue gas at Inner Mongolia Hengkun Chemical Co., Ltd. has been registered. The project owner is Inner Mongolia Hengkun Chemical Co., Ltd.; the construction funds are to be provided by the company itself, with a 100% funding contribution from the company, and the tendering party is Inner Mongolia Hengkun Chemical Co., Ltd. The project is now ready for bidding, and a public tender is being conducted for this EPC project. 2. Project Overview and Scope of Bidding 2.1 Project Overview The flue gases from coke ovens contain large amounts of sulfur dioxide (SO2) and nitrogen oxides (NOx). When released directly into the atmosphere, SO2 and NOx contribute to and exacerbate photochemical pollution and acid deposition, severely affecting air quality. This, in turn, poses significant threats to human health and ecosystems, and constitutes a major obstacle to the sustainable economic and social development of our country. On January 15, 2024, five ministries and commissions, including the Ministry of Ecology and Environment, jointly issued the “Opinions on Promoting Ultra-Low Emissions in the Coking Industry” (Document No. Huan Da Qi [2024] No. 5). This document requires coking enterprises to carry out ultra-low emissions renovations across all processes. In particular, it mandates that such enterprises take measures like constructing backup facilities or modifying multi-chamber systems to effectively reduce pollutant emissions during maintenance of pollution control equipment. In accordance with Article 99, Paragraph 2 of the Law of the People’s Republic of China on the Prevention and Control of Air Pollution, those who emit air pollutants in excess of the permitted emission standards or beyond the set total emission limits for key air pollutants shall be ordered by the environmental protection authorities of the people’s government at or above the county level to make corrections, or to restrict production or suspend operations for rectification; in addition, a fine of not less than 100,000 yuan but not more than 1 million yuan shall be imposed ； In cases of serious circumstances, with the approval of the people’s government vested with the authority to grant such approval, orders may be issued to suspend operations or close down the business. The coking workshop of Inner Mongolia Hengkun Chemical Co., Ltd. is equipped with 2 carbonization chambers of the ZHJL5552D type – double-flue, with exhaust gas recycling, bottom injection, and single-heating side-loading tamping coke ovens. The scale of this oven set is 2*65 chambers; it was put into operation in September 2011. Currently, a semi-dry desulfurization and denitrification system and a wet desulfurization system (without denitrification functionality) operate as backups for each other. However, the wet desulfurization system fails to meet the limits specified in Table 5 of the “Emission Standards for Pollutants in the Coking Chemical Industry” (GB16171-2012); the allowed levels for sulfur dioxide, particulate matter, and nitrogen oxides are 50, 30, and 500 mg/m³ respectively. The semi-dry desulfurization and denitrification system requires about 30 days of shutdown for maintenance each year, and during these periods, levels of substances such as sulfur dioxide and nitrogen oxides exceed the allowed limits. Additionally, due to the limitations of this semi-dry desulfurization and denitrification process, the suction capacity of the coke ovens is low, which hinders further increases in production volume. The Inner Mongolia Autonomous Region requires that the relevant emission limits specified in Document No. Huan Dian Qi [2024] 5 come into effect on January 1, 2026. During system maintenance, various pollutants can exceed permissible levels significantly, leading to severe penalties related to environmental protection as well as restrictions on production or even shutdowns of the facilities. To meet the requirements for ultra-low emissions, it is now necessary to upgrade the existing wet desulfurization and denitration systems for coke oven flue gas, in order to avoid such environmental penalties. For these reasons, the company plans to install a set of backup flue gas desulfurization and denitrification equipment for coke ovens. 2.2 Scope of the bidding: This project involves a tender for design, procurement, and general construction (EPC) of the works, focusing on the upgrading of the existing wet desulfurization and denitration systems for coke oven flue gas, as well as the installation of a new set of denitration systems based on \"dry desulfurization (columnar calcium-based moving bed) + SCR (using medium- and low-temperature manganese-iron-based denitration catalysts that are not hazardous waste)\\". The scope of the tender includes all aspects of the project, such as construction drawing design, changes to the overall plant layout, procurement and transportation of equipment (including catalysts for initial filling) and materials, civil engineering construction, installation work, programming and debugging of the automation control system as well as its integration with the tenderer’s existing control systems, personnel training, commissioning tests, final acceptance, and post-completion tests. The contractor is fully responsible for project management, quality control, safety, schedule adherence, fire protection, environmental protection, energy efficiency, lightning protection, occupational health and safety, asset inventory, and quality assessment, with the ultimate goal of delivering a \"turnkey\" project that meets technical requirements, performance standards, and quality specifications to the tenderer. All activities that rely on existing systems and facilities, including the design and construction of those parts that are connected to such systems and facilities (including any possible modifications to them), as well as procurement, are all included within the scope of this tender. Bidders must conduct on-site inspections prior to submitting their bids in order to finalize the relevant plans. If a bidder fails to carry out an on-site inspection or fails to include the costs associated with design, construction, and procurement in its bid, it will be assumed that these costs are already included in the bid amount, and the tenderer will not bear any additional expenses.
