China Petroleum Network News August 9th, Jilin Petrochemical Co Research Institute completed the "fertilizer plant steam condensate treatment and reuse technology research" results through expert acceptance, and entered the preparatory stage of industrial applications. According to the person in charge of the project, after the implementation of the project, through the reduction of sewage charges and water conservation, is expected to earn 1 million 950 thousand yuan per year.
"Steam condensate treatment and reuse technology" is aimed at chemical fertilizer plants after stripping process condensate, as well as the device produced carbon black water technology research. Condensate does not meet the requirements of water supply, carbon black water by filter press, carbon black after the recovery is discharged, resulting in waste.
Environmental Protection Research Institute of Jilin Petrochemical respectively in the desalted water and circulating cooling water for reuse, a large number of experiments, proposed condensate biological filter filtering process, which can meet the requirements by using plant demineralized water reuse; the carbon black coagulation adsorption stripping process. The effluent can reach the circulating cooling water with recycled water quality standard, evaluation system using circulating water treatment chemicals, water treatment chemicals preferred optimal dosing scheme; put forward fertilizer plant condensate and carbon black water treatment and reuse project.
After calculation, the project has not only saved water, but also has better environmental and economic benefits after the implementation of the chemical fertilizer plant.
