Abstract

요소제조공정에서 원료로 사용되는 탄산가스에는 미량의 수소가스가 불순물로 함유되어 있어서 부식억제책으로 별도 주입한 산소와 함께 폭발성이 강한 수소와 산소의 혼합기체를 형성하게 된다.
최근에 Stamicarbon회사에서 보다 효율적인 요소제조공정을 개발하였으나 상기폭발성 문제점을 정개하지 못하여 실용화에까지 이르지 못한 것을 충비기술진에서 다시 연구한 결과, palladium 촉매에 의한 수소가스 제거공정을 적용함으로써, 이 점을 해결하였다.
In the new Stamicarbon urea process, there exists a danger of possible formation of an explosive mixture of hydrogen and oxygen in the crude carbon dioxide gas. By use of the palladium catalyst, we have been able to eliminate the trace of the hydrogen in the gasstream and thus remove the danger. This results in a safer and more economical process for commercial production of urea.
