General 1.1 Foreword In Shanghai Meishan Iron and Steel Co., Ltd., coke oven No. 1 was put into operation in 1970 and No. 2 coke oven was put into operation in 1971. Both coke ovens are of type 58-II in 65 ducts and have been operating for over 30 years. They are aged with backward technology, featuring high consumptions and unable to meet the modern environmental protection requirements; No. 3 coke oven is of type JNX43-58 in 65 ducts, and was put into operation in 1996. Baosteel Chemical Meishan Branch is subordinated to Shanghai Baosteel Chemical Co., Ltd. under the Baosteel Group. The coal gas purifying system of Baosteel Chemical Meishan Branch is the associated production facilities of the 3 coke ovens of Meishan Iron and Steel Company, built in early 1970s. Due to the long history of the Branch, the gas purifying system equipment has become aged, with serious corrosion, backward in technology and low in automatic control level, resulting in many leaking points in the production area that are difficult to control. The existing facilities and production, equipment and environmental protection level cannot meet the daily increasing requirements in environmental protection. To meet the requirements of modern environmental protection and the admitting conditions set by the state for coking industry, the Company has decided to perform relocated transformation for the three existing 65-duct coke ovens (the site being the newly requisisted land of Meishan Iron and Steel Company), and a new associated gas purifying workshop will also be built. It has been determined that the scale for relocated overhaul of 1# and 2# coke ovens will be 1 million t/a of coke, and the coke ovens will 2
