  4. 제2항에 있어서, HTDC가 약 대기압 내지 약 200psig의 압력범위에서 작동하는 비-비등반응기이며, 유출물이 반응기로부터 나오는 액체 곁흐름임을 특징으로 하는 방법.
  5. 제2항에 있어서, 배출흐름에 있는 물이 800ppm이하임을 특징으로 하는 방법
  6. 제5항에 있어서, 배출흐름이 약 70℉내지 약 130℉온도범위에서 상부콘덴서와 상부농축물드럼에서 나오는 결합된 비-응축상부가스를 포함하고, 배출흐름이 두단계, 첫단계에서는 비-응축물이 약 20℉내지 약60℉ 온도범위에서 떠나고, 두번째 단계에서는 비-응축물이 약 -60℉온도덤위에서 떠나는, 에서 응축됨을 특징으로 하는 방법.
