Good results achieved in the renovation of steam condensate water at Shanxi Coking Company / Author/Source: Sinochem New Network / Date: 2020-08-20 / Clicks: 6. Just a few days ago, the project to renovate the steam condensate water system in Shanxi Coking Company’s water treatment plant was completed after more than two months of intensive work. Once operational, this system can reduce the amount of desalinated water used by about 60 tons per day, saving over 900 yuan in water costs; over the course of a year, this can result in savings of more than 270,000 yuan. The renovation of steam condensate is aimed at centrally collecting the steam condensate from the company’s chemical production system’s steam pipes, and then using it as a substitute for some of the costly desalinated water as supplementary water for gas boilers and waste heat boilers. This approach helps to save water and reduce the amount of wastewater discharged. Guo Zeng, the director of the water treatment plant, explained that this system collects the steam condensate from the steam pipes into a collection tank. When the water level in this tank rises to a set height, a level gauge and an automatic start/stop control system send signals to activate the condensate pump, which then pumps the collected steam condensate into the soft water tank located in the gas boiler room. Once the water level in the collection tank drops to the lowest set level, the pump stops automatically and the process of filling the tank resumes. The soft water pump then supplies water to various users as needed, thus enabling the recycling of steam condensate through this cycle. It is reported that, based on the results achieved after the renovation, Shanxi Coking Company has included the recycling of steam condensate from the alcohol-ammonia temperature and pressure reduction system in its implementation plan, with the aim of further tapping potential and increasing the amount of condensate recovered.
