Call for Bids for the EPC General Contracting Project for Replacing Liquid Ammonia with Urea as a Reducing Agent in Flue Gas Denitration at Hubei Company of Inner Mongolia Company – Author/Source: Date: 2022-04-26 Clicks: 9 1. Bidding Conditions The name of this bidding project is: Public Bidding for the EPC General Contracting Project to Replace Liquid Ammonia with Urea as a Reducing Agent in Flue Gas Denitration at Hubei Company of Inner Mongolia Company*. The bidder is Inner Mongolia Guohua Hulunbuir Power Generation Co., Ltd., and the project owner is also Inner Mongolia Guohua Hulunbuir Power Generation Co., Ltd.; the funding for this project comes from internal sources. *The tender conditions for this project have been met; therefore, a public tender with post-qualification review is being conducted domestically for this project. 2. Project Overview and Scope of Bidding 2.1 Project Overview, Scope of Bidding, and Division into Bids/Packages: 2.1.1 Project Overview: The site of Inner Mongolia Guohua Hulunbuir Power Generation Co., Ltd. (hereinafter referred to as “Hulunbuir Company”) is located to the south of the Baorixile Coal Mine, approximately 14 km away from Hailar District. The boiler for the first phase’s two 600 MW supercritical units is a 600 MW lignite-fired supercritical once-through boiler independently developed by Harbin Boiler Co., Ltd. The boiler model is HG-1913/25.4-HM15, and it is designed to burn coal from the Borixile open-pit mine. Unit 1 completed its 168-hour trial operation in one go on November 20, 2010, and was handed over for commercial operation ； Unit 2 completed its 168-hour trial operation in one go on December 1, 2010, and was handed over for commercial operation. Hubei Company uses the selective catalytic reduction (SCR) process for boiler denitrification; the reducing agent for this process is liquid ammonia purchased from external suppliers. The denitrification reactors are located between the economizer and the air preheater. Each unit is equipped with two SCR reactors, with the catalyst layers arranged in a 2+1 configuration. Currently, two layers of catalysts have been installed, with one layer reserved as a backup. The denitrification system is designed to handle an NOx concentration of 350 mg/Nm3 at the SCR inlet (under standard conditions, on a dry basis, with 6% O2). By 2016, both units had undergone upgrades to achieve ultra-low emission levels, with NOx emission concentrations below 50 mg/Nm3. The denitrification ammonia area is located on the northwest side of the plant site and consists of a truck loading/unloading area, a liquid ammonia storage area, and an evaporation area. The ammonia area is equipped with two 80 m³ horizontal liquid ammonia storage tanks, with a total liquid ammonia storage capacity of approximately 56 tons; this constitutes a major hazard source. To ensure the personal safety of power plant personnel and the safe and stable operation of all units in the plant, as well as to build a safe, green, and environmentally friendly power plant and achieve its sustainable and coordinated development, Hubei Company has decided to renovate the denitrification ammonia area. This will eliminate major hazards associated with the ammonia area and replace the liquid ammonia-based ammonia production process with a urea-catalyzed hydrolysis process for ammonia generation. 2.1.2 Scope of bidding and division of packages: The EPC project for replacing liquid ammonia with urea as the denitration reducing agent for the flue gas of two 600 MW-class boilers at Inner Mongolia Guohua Hulunbuir Power Generation Co., Ltd. (hereinafter referred to as “Hulunbuir Company”) (hereinafter referred to as the “Project”). This includes all tasks related to the design, procurement of equipment and materials, manufacturing, supply, transportation, and storage; construction and installation; metal testing; commissioning; a 168-hour continuous trial run; performance testing; project completion; engagement of a qualified entity to conduct the “three simultaneities” assessment and acceptance of safety facilities; engagement of a qualified entity to handle the approval, filing, and final acceptance regarding the environmental impact assessment under the “three simultaneities” principle; engagement of a qualified entity to carry out the “three simultaneities” assessment and acceptance concerning occupational health; energy conservation evaluation; submission for review and acceptance of fire protection designs, as well as fire protection filing; engagement of a safety assessment agency to prepare an evaluation report on the deregistration of major hazard sources; registration and filing of newly added special equipment; third-party reviews, acceptance, performance testing, defect rectification, training; transition of the two ammonia production systems, and their eventual commissioning and handover. The project also includes the demolition of old facilities in the area containing raw ammonia, site hardening, road planning, as well as the removal and disposal of waste materials in accordance with relevant laws and regulations. This also includes, in accordance with the requirements of local **departments** such as quality supervision, technical supervision, and engineering management, handling the registration of usage certificates for special or unique equipment such as pressure pipelines, pressure vessels, and lifting equipment; non-destructive testing of pressure pipelines and pressure vessels; as well as periodic inspections regarding quality and safety.
