Abstract:
The company GAA has commissioned us to design a finishing train for a polyethylene glycol production plant in order to increase the production capacity and performance of the reactor. The 3 end products of the process are: PEG 3350, PEG 600 and PEG 1450. With an annual production of 60,000 MT, of which 18,000 MT per year of PEG 3350, 18,000 MT of PEG 600 and 24,000 MT of PEG 1450. For the production of the three polyethylene glycols, they are discharged from the reactor into two Rundown tanks where they are mixed with the magnesium silicate, in such a way that cross-contamination is avoided and the three products can be produced in the same reactor. Once mixed, they will pass through a filter that uses Fundabac candela filtering technology, capable of automating the process and reducing contact between workers and the product, which can filter the three products sequentially to obtain the desired purity without shutting down the reactor. Once the product has been filtered, it is sent to a check tank to verify that it is within specification. In the completion of the finishing train, the different P&ID's (piping and instrumentation diagram) of the equipment, the PFD (process diagram), the design and sizing of the equipment to obtain greater productivity have been carried out. An economic study has been carried out to determine the viability of the project and it has been determined that it is profitable with an VAN of 17.5 M€ over 10 years with an interest rate of 15% and an TIR of 36%.
