Abstract
This disclosure relates to a system and method for controlling a carbonaceous feedstock into a devolatilization reactor. The system includes a control valve system for modulating slurry. The control valve system includes a valve, an actuator, and a position controller. The valve includes a flow restrictor and a seat. The valve may be configured to control the flow of the slurry, wherein when the flow restrictor is engaged with the seat, the valve is in a close position, and when the flow restrictor is not engaged with the seat, the valve is in an open position. The actuator may be configured to control opening and closing of the valve. The actuator may be coupled to the position controller. The position controller may be configured to determine the position of the actuator. The seat may be configured to support the flow restrictor.
