Producing vinyl monomers is the gateway to the plastics industry, and has been around for decades. The industrial processes for making monomers have become very efficient, with many advances in reaction, distillation and storage technology. However, even today not every plant runs smoothly all the time, and the process can be costly when a plant goes down – for these producers, down time is real money. Fouling is one of the most common problems in the manufacturing of petrochemicals and in particular of vinyl monomers. Deposits of polymeric and other insoluble materials conspire to limit the efficiency of the process. Standard solutions to this problem are to reduce throughput, reduce process temperatures, and on a broader level, to redesign the plant. Although such solutions may reduce fouling, they may also reduce productivity or involve capital investment.
