Energy-saving renovation using lightweight calcium carbonate
Thread Content
Universal Hai Chuan Hai, hello! We are a company that produces light calcium carbonate using limestone and anthracite as raw materials. While anthracite is used as a raw material, biomass fuels such as wood chips are employed as fuel for all subsequent processing steps. Now, due to environmental regulations, the use of anthracite as a raw material and biomass as fuel has been prohibited; improvements must be made this year. The available options are natural gas and alcohol-based fuels. Obviously, the choice is pretty much unanimous: natural gas. It is indeed clean, and its cost is also much lower than that of alcohol-based fuels. However, we’re not familiar with the technical aspects involved, nor do we know how to meet the required standards while also ensuring energy efficiency. Could any experts provide some guidance or offer cooperation? Thank you so much! Waiting online!
:) The raw materials are no longer allowed to be used? Then wouldn’t your entire manufacturing process have to be changed? Environmental regulations have been too strict in recent years; anthracite is indeed no longer allowed to be used.
It has to be changed. . . . But using natural gas to burn limestone is, damn, such a luxury. The key is whether one understands the subject or not.
Have you consulted your peers? This environmental regulation is really forcing companies to change their business areas! It is recommended to consult peers first. If you don’t understand, you can learn it. The fear is that the huge investment will be too much for the company to bear. That’s not good.
It’s not a question of whether to consult or not; it must be done, otherwise the factory will have to close. But as for the specific steps, one needs to consult experts in detail.
There is a low-energy process that can produce precipitated calcium carbonate without calcining limestone.
It involves first turning it into gypsum, or using gypsum as a raw material to react with carbonates at low temperatures to produce light calcium.
This won’t work; the only raw material available here is limestone, which can only be processed into quicklime through calcination in a lime kiln.
