Key points for controlling the temperature of the main tower reactor: 1. Factors affecting the temperature of the main tower reactor: 1. Liquid level in the main tower reactor. 2. Main return flow rate. 3. Steam addition rate to the main tower boiler. 4. Predictive flow. 5. Preconditioning fluid temperature. 6. Pressure at the base of the main tower. 7. Production rates of isobutyl oil and isooctane. II: Key adjustment points: 1. Stabilize the liquid level in the bottom of the main tower: Maintain the normal liquid level at 40%–50%. Adjustment methods include: (1) Adjusting the flow rate of the pre-treatment liquid. (2) Adjust the main return flow rate. (3) Adjust the steam flow rate to the main tower boiler. (4) Adjust the residual liquid discharge valve. 2. Maintain normal reflux ratio values: Control the reflux ratio between 1.7 and 2.0. Methods for adjustment include: (1) reducing or increasing the production from the main tower. (2) Adjust the prognostic flow rate. (3) Adjust the steam flow rate to the main tower boiler. (4) Adjusting the main reflux temperature means adjusting the amount of circulating water in the tower top reflux condenser. 3. Control the steam flow to the boiler in the main tower using a control valve: to stabilize the heat at the bottom of the main tower. The adjustment method mainly involves adjusting the opening degree of the main tower steam control valve. 4. Adjust the flow rate of the conditioning solution: maintain a stable feed rate to the main tower. The main adjustment method is to adjust the control valve of the prognosis pump feed line. 5. Precipitate liquid temperature control: The main method of adjustment is to regulate the flow rate of the condensate water entering the precipitate preheater. 6. Main tower pressure regulation: The adjustment methods include (1) adjusting the steam flow rate to the main tower boiler. (2) Adjust the circulating water flow rate of the tower top reflux condenser. (3) Adjust the reflux flow rate. 7. Regulating isobutyl oil and isoheptane recovery: The main method of regulation is to adjust the flow rate using on-site flow meters.
