Plastic corrugated plate packing has advantages such as light, high capacity, low pressure drop, large specific surface area, easy replacement, etc. It is widely used in unit operations like rectification, absorption and extraction. The material's heat resistance reaches 100°C for PP and 150°C for PVDF. The packing sheet may be perforated with small holes to increase mass transfer efficiency. If the separation requirement is not high, it needs no perforation to increase sheet stiffness.
Suitable for the absorption process under normal temperature and pressure 0.1 – 100 KPa, and for the reflux recycle of little spray, eg. exhaust gas cleansing. Usually, it’s used in water, acids, alkali solvent to absorb NH3, HCl and SO2 under low temperature (below 80 centigrade). And it can absorb the solvent infiltrations in the water, such as acetone, methanol, ethanol, formaldehyde, etc. It can be sued for absorbing the chemicals with very bad smell, such as amine, mercaptan, etc.
The Plastic Corrugated Plate Structured Packing has the advantages of light weight, big flow, low drop pressure, big specific surface, easy change, etc. It’s able to endure 100 centigrade if it’s made of PP. And it’s able to endure 150 centigrade if it’s made of PVDF. The plastic plate can be perforated to increase the transfer efficiency.
This packing is widely used in the operation of absorption and decomposing absorption units, it’s especially used in the production procedure of heavy liquid loading and high operative pressure, such as hydrochloric acid (HCl) and sulphuric acid (H2SO4) production, deaerating CO2 and H2S from natural gas, drying chlorine, making ammonia liquid, waste gases purification and decomposing absorption deaeration apparatus.
