Replacement waste heat boiler for formaldehyde plants
In the production of formaldehyde, managing the high temperatures generated during methanol dehydration is essential. Traditional methods often fail to efficiently recover the significant amount of heat produced, leading to energy losses and reduced operational efficiency.
Recover heat from formaldehyde production processes
The replacement waste heat boiler by BORSIG is designed to meet the specific requirements of formaldehyde plants using the Silver Contact Process. This system effectively recovers heat from the heated product gas mixture of methanol, water, and air, which heats up to 600 to 700 °C during oxy-dehydration reactions. Integrated directly into the reactor, the waste heat boiler produces saturated steam as the gas cools down to 150 °C, which can then be utilized in the main process. Characterized as a fired-tube boiler, it ensures optimal energy recovery and operational efficiency. BORSIG’s boilers typically operate with pressure parameters at 20 bar (2,000 kPa) and temperatures at 200 °C, and are built to replace existing units provided by BORSIG or STEINMÜLLER. This product is essential for plants focusing on nitric acid, formaldehyde, and caprolactam production.
