ʻO ke apo ʻo Raschig ka mea mua loa i hoʻomohala ʻia i ka packing random, he ʻoki ʻoki liʻiliʻi ia, ʻo ia ka mea ma waho o ke anawaena e like me kona kiʻekiʻe, e hāʻawi ana i kahi ʻili no ka (re) evaporation o ka hapa nui loa i ka refluxing distillate. paʻa kemika, a me ka hoʻomanawanui wela maikaʻi loa, hiki i ka Ceramic Raschig Ring ke pale i ka wela kiʻekiʻe, ka waikawa (koe wale ka HF), ka alkali, ka paʻakai a me nā mea hoʻoheheʻe kūlohelohe.Hoʻohana nui ʻia i loko o nā hale kiaʻi packing like ʻole o ka desiccation, absorption, cooling, washing, and regeneration in the industry of petrochemical, chemical, metallurgy, gas and oxygen generation.No ke apo raschig me ka nui nui ma luna o 100mm, hoʻopiha mau ʻia i ke kolamu i hoʻonohonoho pono ʻia.Inā emi kona nui ma mua o 90mm, ua hoʻopaʻa ʻia ke apo raschig i loko o ke kolamu.
