摘要

Abstract

In this work

the absorption-hydration hybrid method was used to recover (hydrogen+nitrogen) from (hydrogen+nitrogen+methane+argon) tail gas mixtures of synthetic ammonia plant through hydrate formation/dissociation. A high-pressure reactor with magnetic stirrer was used to study the separation efficiency. The in-fluences of the concentration of antiagglomerant

temperature

pressure

initial gas-liquid volume ratio

and oil-water volume ratio on the separation efficiency were systematically investigated in the presence of tetrahydro-furan (THF). Antiagglomerant was used to disperse hydrate particles into the condensate phase for water-in-oil emulsion system. Since nitrogen is the material for ammonia production

the objective production in our separation process is (hydrogen+nitrogen). Our experimental results show that by adopting appropriate operating conditions

high concentration of (hydrogen+nitrogen) can be obtained using the proposed technology based on forming hydrate.
