What are the Water Ballast Process and its functions?
The respective functions of the Water Ballast Process, in the production of formaldehyde through the vaporization of methanol with air and water stems asserts various intrinsic approaches in order to address the various entailed functions effectively. The ultimate conversion of the methanol is concluded through the passing of the vaporized methane through the catalyst beds in order to trigger the respective chemical reaction required for the undertaken process. Moreover, the respective temperature range required for the optimum relay of the entailed processes assert the maintenance of temperature ranges of the included furnaces to be between 550 to 720C. Furthermore, the resultant gaseous formaldehyde extricated through the process is then cooled in the relevant absorption towers in varying solutions respective of the type of end product being required by the process.
According to the process flow diagram depicting the associated processes for the unit operations that occur in the Water Ballast Process for producing Formalin 37/3, fresh methanol is inducted into the process chamber to be mixed with recycled methanol, with the corresponding temperatures being 30C and 68.3C respectively, and the pressure gradients of 14.7 psia and 16 psia. The forwarded mixed methanol for further processing is rendered at 35.4C and pressure of 14.7 psia. For further processing, higher pressure are required. These are established by the pump, which pushes the pressure gradient up to 35 psia of the overall mixed methanol for further processing.
