Producing sodium bicarbonate using carbon dioxide captured from the flue gasses of waste incineration (NAHCO3)

Download PDFDownload PDF
In this project Twence will demonstrate an innovative technology for re-using carbon dioxide by capturing the waste product from the flue gasses of the Waste-To-Energy (WTE) plant and using it for the production of sodium bicarbonate (NaHCO3) as a result of the alkaline reaction with either sodium hydroxide (NaOH) or with soda (Na2CO3). The choice for the product to be used is largely depending on the price level and large-scaled availability of the raw materials. The sodium bicarbonate will be used at the incinerator for flue gasses cleaning purposes (removal of acid components), thus avoiding the current expensive purchase of sodium bicarbonate.

Results

  • Validation of the chemical, thermodynamic and physical properties of the system; Validation of the process models, model calculations and simulations; Validation of the effects of the process conditions on the product properties .
  • Detailed design of both the carbon capture plant as well as the sodium bicarbonate reactor; Construction of a demo plant with a capacity of 8,000 tons of sodium bicarbonate on an annual basis; Technical evaluation of both the carbon capture process as well as the re-use process; Integration of the demo plan with the regular WTE-plant (specifically with the flue gasses cleaning system).
  • Availability, volumes and prices on the raw materials; Evaluation of the storage, transport and recycling of raw materials and finished product; Business process evaluation (operational costs, level of investment and return-on-investment); Calculation of the market volume of the demonstrated technology.
