Years of continuous improvement and development of the PET process have culminated in the DHI process and eliminated the Solid State Polycondensation step. The ***dealdehydization*** (DAH) step is integrated with palletization and crystallization to remove the acetaldehydes. By reducing the number of process steps, the DHI process increases yield, resulting in lower energy consumption (utility cost savings), less capital investment, which directly translates to CAPEX and OPEX savings.
