Abstract
본 발명은 반응장치를 조업중지 또는 냉각할 필요없이 탄화수소 반응공정 경로를 코크스제거하는 방법에 관한 것으로서, 탄화스소 공급 흐름을 차단하는 단계와, 코크스가 제거될 때까지 코크스의 연소를 위해 증기 매트릭스 안으로 제한된 지속시간 동안 일련의 공기펄스를 유입시키는 단계와, 탄화수소 공급을 재개하는 단계를 포함한다.The present invention relates to a method for coking off a hydrocarbon reaction path without the need to shut down or cool down the reactor, the method comprising the steps of shutting off a carbon carbide feed stream and into the vapor matrix for combustion of coke until coke is removed. Introducing a series of air pulses for a limited duration and resuming the hydrocarbon feed.
