Gas-Phase Polyethylene Production Technology (SGPE)

1. Simplicity of process, less equipment, less material consumption, less energy consumption;
2. Because of the absence of solvent and of high activity of catalyst, solvent recovery, catalyst and oligomer removal are not needed;
3. Mild operation condition, high operation flexibility, smooth grade switch and stable product quality;
4. Condensing operation mode effectively solves the problem of removal of reaction heat, so time space yield of reactor is improved greatly;
5. Less waste emission and meeting environment requirement easily;
6. Compact plant design, small floor area, less operation and maintenance staff, less capital investment and operation expense.
