Heating of wastewater containing polymers
Thread Content
In 2005, two heating furnaces were installed at Daqing Junan to heat water containing 1% polymer and 2% oil. The furnace operated well for the first two months after installation, meeting all the design requirements. After running for two months, the temperature of the hot water failed to meet the design requirements; the design specification was 80°C, but in reality it only reached 50°C. What is the reason for this? Is it due to the polymer? Because other furnaces designed in the same way are all operating normally. 5
Molecules with a relative molecular mass of over 10,000 are generally referred to as polymers. Polymers are usually composed of 103 to 105 atoms connected by covalent bonds. Since polymers are mostly produced by the polymerization of small molecules, they are also often referred to as polymers or polymeric substances; the small molecules used in polymerization are called “monomers”. Low-molecular-weight compounds that can undergo polymerization are called monomers; their main components are carbon and hydrogen. Under certain conditions and with the action of catalysts, monomers polymerize to form long chains with carbon atoms as their backbone, which are then known as polymers. Polymer compounds have almost no volatility and exist in solid or liquid state at room temperature. Regarding the issue of tank heating mentioned by the poster, I think there’s a problem with the heating component; it would be advisable to check that part.
This type of heating device is used in oil field gathering and transportation processes, and the polymer it contains is polyacrylamide. After various tests, there is no issue with the heating section; the problem is that the heat supplied does not get carried away by the water. Does the presence of this substance in the water have a significant impact on heat transfer?
