New developments since the operation of the flue gas desulfurization unit
Thread Content
- Our company’s catalytic flue gas desulfurization project is about to be completed and put into operation. After commissioning, SO2 emissions will **decrease**, and will be well below the levels specified by environmental authorities. Due to the high operating costs of flue gas desulfurization, the company’s management plans to operate this facility intermittently, as long as the total amount of SO2 emitted does not exceed the allowed limits. I wonder if any of you sea friends have encountered similar situations – is it appropriate to do this?
Where is it? Could you reveal that? It’s probably not possible to disconnect the catalytic flue gas system intermittently, as doing so could lead to corrosion at the connection points.
What process, liquid-phase absorption?
It is BELCO’s wet process.
Installing flue gas desulfurization units considers economic benefits on the one hand, and improving the environment is another very important aspect. Generally, the working areas and residential zones of petrochemical plants (refineries) do not have good environmental conditions, with severe air pollution. From the perspective of ensuring the health of employees and their families, it should continue.
Reply 1# Clauspolunit: Could the original poster give some introduction? Why are the operation costs so high? Isn’t just sodium hydroxide used? We’re also getting ready to go
The cost is even higher if sodium hydroxide is used. We use magnesium hydroxide.
The operating costs for flue gas desulfurization are relatively high; currently, this is an inevitable trend.
The operating costs are very high; it’s several tens of millions per year! It seems that there aren’t many companies in the country that use this device; however, all new projects now have to use it, and Beihai Petrochemical is planning to adopt it as well.
Our factory hasn’t used it yet; maybe it’s a public relations issue
The flue gas desulfurization unit, in addition to having high operating costs for treatment, is likely to generate wastewater, which requires close attention to prevent the spread of pollution.
