Application
The pilot unit simulating the delayed coking process is designed to scale the coking technologies of heavy oil residues and secondary gas oil fractions.
3 devices are included in the set:
- Stand A is designed for simulating both dynamic and static coking modes in automatic mode;
- Stand B is designed to simulate the static coking mode;
- Muffle furnace for final cleaning of coke.
Stand – A
The reactor is made of steel and is equipped with flange seals with a reusable gasket, has a range of operating temperatures up to 600°C and operating pressures up to 1 MPa. Reactor dimensions: height 574 mm, internal diameter 94 mm. The reactor furnace is a three-zone flap , temperature up to 650°C.
Preheater (1.5m, 3m, 6m) is a stainless steel spiral tube located in the third zone of the furnace.
A plunger pump for feeding raw materials into the reactor with a head heated to 100°C and a capacity of 0.4 to 4 l/hour is installed.
Inert gas flow formed by an electronic mass gas flow controller (from 0 to 1000 ml/min)
raw material container with 8 liters capacity, pressurized with nitrogen, removable for weighing, equipped with a stirrer with a drive, is placed in a heat-insulated glass heated to 100°C.
There is a 3-stage separator with condenser-refrigerators at the input of each stage. The temperature of the first of them is 80 ÷ 30°C, the second 30: 0°C, the third 10 ÷ -10°. The temperature of the first stage is maintained by an automated heat exchanger, the second and third - by a cryostat. The volume of each separator vessel is 2 liters.
Automation unit on LCD + PLC.
