Inlet diffuser for fixed-bed reactors

A fixed-bed reactor for uniform liquid distribution, the fixed-bed reactor comprising:

• a feed pipe for introducing a stream of gas-liquid mixture into the reactor;
• a catalyst bed comprising catalyst downstream to the feed pipe;
• a distribution tray above the catalyst bed and comprising distribution units for distributing the stream of gas-liquid mixture on the catalyst bed;
• an inlet diffuser between the feed pipe and the distribution tray for uniformly distributing the stream of gas-liquid mixture on the distribution tray;
• and
• an outlet for conveying the stream of gas-liquid mixture out of the reactor,
• wherein the inlet diffuser comprises:
• a truncated cone adapted to receive a stream of gas-liquid mixture, wherein the truncated cone includes at least one opening formed on a circumference of the truncated cone;
• a vertical baffle plate in each of the one or more openings in truncated cone to break the stream;
• at least one horizontal baffle coupled to the truncated cone and adapted to absorb momentum of the stream received by the truncated cone;
• a cylindrical chamber in fluid communication with the truncated cone and adapted to receive the stream from the truncated cone, wherein the cylindrical chamber includes at least one slot adapted to discharge the stream from the inlet diffuser;
• and
• a splash plate disposed at a bottom portion of the cylindrical chamber and comprising one or more apertures adapted to discharge the stream from the inlet diffuser.
