The furnace designed for heating and partial evaporation of diesel fraction coming from column cubeТ-401, with subsequent return into T-401 column as a “hot stream”.
features
Operation conditions should correspond to U, HL by GOST 15150-69.
Placement category –1 by GOST15150-69.
Maximal block installation area seismic activity – 6 points by SNiP 11-7-81.
The furnace has 2 coils:
1) Coil №1 works with diesel fraction;
2) Coil №2 works with fuel gas.
