Definitions
- the present invention relates to the use of a plate heat exchanger as feed/effluent heat exchanger in multiple reactor systems.
- Plate heat exchangers are generally formed by an elongate impervious chamber and a bundle of plates arranged in the chamber and providing therewith a free space.
- the plate bundle consists of a stack of mutually parallel plates that provide between them a double circuit for the flow of two independent and generally counter-current fluids.
- a plate heat exchanger is a compact, cost efficient heat exchanger solution which is used whenever the process conditions can allow it. High pressure, above 10-20 bar, and a heavy fouling feed stream represent typical
- feed/effluent exchangers E are used as shown in the appended figure.
- the principle is that cold feed gas (1) is heated by the outlet gas (2) from the reactor (s) R.
- the absolute pressure in such a feed/effluent exchanger can be high, i.e. up to several hundred bars, but the pressure difference is limited to the pressure drop in the reactor system, which can be kept below 20 bar, preferably below 10 bar. This allows for use of a plate heat exchanger as feed/effluent exchanger, provided that it is installed in a pressure shell that can withstand the high absolute pressure.
- US 9.120.068 describes a chemical isothermal reactor with an internal plate heat exchanger having heat exchange radial plates and radial ducts parallel to sides of the plates for distributing and collecting a heat exchange fluid. A part of the radial ducts has a smaller cross section near the inner converging ends .
- WO 2007/096699 describes a multiple reactor chemical production system, where multiple reactors in a common pressure shell one by one are connected to multiple plate type feed/effluent exchangers in a common pressure shell.
- reaction conditions are adjustable to the respective local
- composition of the reaction mixture and variable over the reactor length A comparison of one standard shell-and-tube type heat exchanger with a plate heat exchanger in a pressure shell results in an advantage for the shell-and-tube type.
- the present invention relates to a process for performing one or more exothermal reactions, wherein a plate heat exchanger is used as feed/effluent exchanger in connection with two or more reactors, which are operating in parallel performing exothermal reaction (s) at a pressure above 30 bar abs .
- the reactors are preferably boiling water reactors, quench type reactors, adiabatic reactors or any combination of these reactors working in series.
- the primary reaction in the reactors is preferably a conversion of synthesis gas to methanol or ammonia or dimethyl ether (DME) or any other exothermal reaction.
- DME dimethyl ether
- this invention provides a process of
