Consult on propylene desulfurization and dehydration technology
Thread Content
What technologies can be used to maintain the sulfur content in propylene at less than 1 ppm and the water content at less than 10?
The control of sulfur content in propylene can be achieved through adsorption techniques or distillation techniques. You can use molecular sieves or activated carbon for deep adsorption to remove sulfur components. At the same time, desiccants such as molecular sieves can be used to remove moisture, ensuring that the water content remains below 10 ppm. Furthermore, the use of integrated desulfurization and dehydration equipment can also be considered to improve processing efficiency and ensure the quality and purity of the propylene product. .
Which technology is currently being mainly used to achieve this goal?
Currently, adsorption technology is commonly used in industry to achieve deep removal of sulfur and water from propylene. In particular, the use of molecular sieves as adsorbents enables effective stabilization of sulfur content at below 1 ppm, thanks to their high efficiency and selectivity; meanwhile, molecular sieves or activated alumina are also used to remove moisture, keeping the water content below 10 ppm. Furthermore, steam or regenerating gas can be used to regenerate the molecular sieve, improving the efficiency of the adsorption cycle. .
