Reactor description with the INS-27C basket

Reactor with the INS-27C basket has two adiabatic catalyst beds, two heat exchangers (1 and 2) as well as an electric start-up heater placed in the reactor’s axis. The gas flow through the beds is axial. Synthesis gas (140 ÷ 200 °C) washes a pressure vessel and flows into the space between tubes in a preliminary heat exchanger (1) and then it flows into the tubes of another inter-bed exchanger (2), where it is heated to 370 ÷ 400 °C. The heated gas is divided into two streams, which flow simultaneously through IA and IB beds, after which they are joined and flow into space between tubes of an inter-bed exchanger (2). Gas from adiabatic beds, after cooling to the temperature of 400 ÷ 420 °C is separated into three streams, which flow simultaneously through IIA, IIB and IIC beds. They are later joined and flow into the preliminary exchanger tubes (1). The post-reaction gas, cooled to 340-380°C, leaves the reactor.
