ZHY-3 delayed coking test device

Product Description:

The delayed coking test device simulates the deep processing technology of residual oil in the laboratory, quickly identifies the process parameters suitable for different residual oil delayed coking, objectively evaluates the effect of delayed coking under different process conditions, and is an ideal pre production experimental device for residual oil secondary processing technology.

Technical parameters:

1. Injection rate: 0.5kg/h to 1.0kg/h

2. Outlet temperature of heavy oil heating furnace heating section: 480 ℃~520 ℃, control accuracy ± 1 ℃

3. The design pressure of the coke tower is 2.0MPa, the operating pressure is 0.14-1.0MPa, and the control accuracy is ± 5KPa

The design pressure of the fractionation tower is 1.0MPa, and the operating pressure is 0.14-0.8MPa

The design pressure of the receiving tank is 1.0MPa, and the operating pressure is 0.1-0.8MPa

4. Water injection rate: 20-200mL/h

Performance characteristics:

1. Equipped with a fractionation tower, the properties of the circulating oil can be analyzed after obtaining it, and the circulating oil can be directly circulated.

2. The heavy oil heating furnace adopts a box type structure with four heating stages. The first stage is a steam generator, and the last three stages are oil steam heating to ensure sufficient heat. Through the reasonable design of the furnace tube and the coordination with steam, the oil and gas in the furnace tube reach a certain line speed to avoid coking.

3. The coke tower insulation furnace is designed in five sections, with three sections for the tower body, one section at the top of the tower, and one section at the bottom of the tower. It can simulate the temperature gradient distribution of industrial coke towers well and ensure the temperature at the top and bottom of the tower.

4. The pressure of the coke tower is controlled through the cooperation of the coke tower top pressure sensor and the pneumatic regulating valve.

5. The device is equipped with a burning system, which can promptly burn the furnace tubes and other parts after each test.

6. The liquid level of the fractionation tower is controlled by a non-contact differential pressure transmitter and a pneumatic control valve.
