Thread Content

The Linfen Wansinda Coking Plant’s upgrade project involves the construction of coking ovens with a capacity of 1.68 million tons per year, and a carbonization chamber height of 6.78 meters. The project is located in the Fushan Shuangxin Industrial Park. The main components of the construction include 127 (63+64) JNDX3-6.78 type coking ovens, each with a carbonization chamber height of 6.78 meters and a single-heating multi-stage heating system. Additional facilities included are a coal preparation system, devices for recovering chemical products, gas purification systems, 2×190 tons per hour dry quenching facilities, as well as environmental protection equipment such as flue gas desulfurization and denitrification systems, along with other auxiliary facilities. Zero discharge of production wastewater; the remaining coke oven gas is sent to Linfen Fuli New Energy Technology Co., Ltd. for the production of LNG as well as hydrogen and liquid ammonia, thereby enabling high-value utilization of coke oven gas. Coal tar can be used as raw material for the project within the park that is planned to process 300,000 tons of coal tar per year, along with the production of 10,000 tons of needle coke. Crude benzene can be sent to another project in the park, which is designed to process 100,000 tons of benzene per year and produce 60,000 tons of 2,4-dinitrochlorobenzene, thereby enabling the centralized deep processing of coal tar and crude benzene within the park. The total investment for the project is 2,066.21 million yuan, with a total land area of 89.92 hectares.
