How many days (hours) was your plant’s sulfuric acid production shut down in 2007?
Excluding the 13-day shutdown for major repairs in August this year, there were a total of 70 hours of minor shutdowns.
The parking time here is calculated on a monthly basis.
Suzhou Shuangshi’s 1 million tons per year sulfur-based sulfuric acid plant is scheduled for a 12-hour shutdown for maintenance in 2007
Does Jiahua Sulfuric Acid undergo major repairs every year? What are the reasons for frequent stops?
Equipment aging, employees’ skill levels and sense of responsibility, as well as climate conditions, all affect the driving rate
Our company waited for three years, from September 2004 to August 2007, before carrying out a major overhaul; other short-term shutdowns were for routine maintenance, including turbine maintenance, repairs for acid leakage in the acid coolers, and sealing up leaks in the flue gas.
What kind of factory is that? It goes through a major overhaul every three years – what luck! I’m really envious
How is the annual inspection for special equipment carried out? **It is stipulated that boilers must be inspected once a year – can this be done without shutting down the plant?
In Suzhou, when producing acid from 40,000 tons of pyrite, the plant is shut down for 1 month per year, and undergoes a major overhaul once a year. When producing acid from 80,000 tons of pyrite, the plant is shut down for 20 days per year, and a major overhaul is carried out every two years. When producing sulfuric acid from 300,000 tons of sulfur, the plant stops operating for 1 day per year, and undergoes a major overhaul once every 5 years. This shows that process management is important; sulfuric acid plants are prone to damage when they are started and stopped frequently, but they won’t get damaged if operated continuously without stops.
