Water recycling system renovation at Weihe Chemical Plant – Author/Source: Sinochem News Network – Date: 2022-03-04 – Clicks: 7. Recently, Shaanxi Weihe Chemical Company completed energy-saving renovations to the water recycling systems in its two methanol production units; the system recovers around 300 cubic meters of water per day, which is expected to save approximately 420,000 yuan in costs each year. It is reported that the vast majority of the equipment in the company’s Dimethylethane production workshop uses water cooling; the cooling water is drawn from the water supply system, and after undergoing the cooling cycle, it is discharged directly into the drainage ditches on site. This not only leads to waste of water resources and increased production costs, but it also causes the ditches to become clogged, making it difficult to clean them. To this end, the company established a special team for water conservation efforts, strengthened the management of water resources allocation, conducted a comprehensive review of water usage, and developed plans for the optimized allocation of water resources in order to improve its water conservation management system. Specifically, the company improves the operational efficiency of its equipment by strengthening daily maintenance efforts, eliminates problems such as leaks and losses, thereby reducing the rate of steam and water loss from the equipment. They also ensure the safe and efficient operation of the equipment by promptly sealing and isolating leakage points, as well as strengthening the maintenance of systems such as those for flash vaporization and desulfurization wastewater to eliminate potential hazards. In terms of device operation management, the company adjusts the operating parameters of systems such as steam supply, condensate volume, and industrial wastewater based on the actual operating conditions of the devices, thereby increasing the rate of wastewater reuse, reducing the amount of fresh water required by water-intensive processes, and cutting water consumption costs.
