Definitions

  • the present application relates to methanol production.
  • Methods for the production of methanol by catalytic conver ⁇ sion of synthesis gas containing hydrogen and carbon oxides have been known for a long time to persons skilled in the art .
  • a methanol plant with natural gas feed can be divided into three main sections. In the first part of the plant natural gas is converted into synthesis gas.
  • the synthesis gas re ⁇ acts to produce methanol in the second section, and metha ⁇ nol is purified to the desired purity in the tail-end of the plant.
  • a reactor such as a boiling-water reactor (BWR) is used to convert the synthesis gas from a reformer/gasifier unit and recycle gas, i.e.
  • BWR boiling-water reactor
  • the Methanol synthesis gas is characterised by the stoichiometric ratio (H 2 - CO2 ) / (CO + CO2 ) , often referred to as the module M.
  • a module M of 2 defines a stoichiometric synthesis gas for formation of methanol.
  • Other important properties of the synthesis gas are the CO to CO 2 ratio and the concentration of inerts.
  • the synthesis gas is often referred to as make-up gas.
  • a high CO to CO 2 ratio will increase the reaction rate and the achievable per pass conversion.
  • the formation of water will decrease, reducing the catalyst deactivation rate.
  • High concentration of inerts will lower the partial pressure of the active reactants.
  • Inerts in the Methanol synthesis are typ ⁇ ically methane, argon and nitrogen.
  • the methanol synthesis is exothermic and the maximum con ⁇ version may often be obtained at low temperature and high pressure.
  • the capacity of methanol plants is increasing to reduce in ⁇ vestments, taking advantage of the economy of scale.
  • the capacity of a world scale plant has increased from 2500 MTPD a decade ago to about 5000 MTPD today. Even larger plants up to 10,000 MTPD or above are considered to further improve economics and to provide the feedstock for the Methanol-to-Olefin (MTO) process.
  • MTO Methanol-to-Olefin
  • a first aspect of the present process and plant is pro ⁇ vided a way to increase the conversion of the CO and C0 2 per pass and in this way increasing the carbon efficiency and/or the synthesis loop recycle gas flow rate and thus improve the energy efficiency and reduce the size of the recycle gas compressor.
  • the present process can be further extended by one or more separator/Methanol reactor sets. For example it is possible to have a series of First reactor - first separator - sec ⁇ ond reactor - second separator - third reactor - third separator etc. In case of more than two methanol reactors the recycle lead to mixing with the syngas is preferably taken from the last separator.
  • the first and second methanol reactor may be of the same or different type.
  • the first reactor and or second reac- tor may be a boiling water reactor (BWR) , an adiabatic re ⁇ actor and/or a quench reactor.
  • BWR boiling water reactor
  • first and second type is the same in form of BWR re ⁇ actors it may be an advantage that the two reactors can be made identical facilitating the reactor manufacturing.
  • the first and second reactor may be of different types. For example if the first methanol reactor is a boiling water reactor the major part of the conversion is done in this reactor and the second methanol reactor can be a simpler type e.g. a simple adiabatic reactor with a relative small ⁇ er catalyst volume.
  • the catalyst in one or more of the Methanol reactors may for example be a known Methanol catalyst such as an Alumina based catalyst.
  • Methanol catalyst such as an Alumina based catalyst.
  • Examples are 6x4 mm Cu/Zn/Al 2 03 catalyst for example Tops0e MK-121 or MK-151 FenceTM.
  • the first reactor and or second reactor can be operated at the same or different inlet temperatures in order to opti- mize the efficiency of the conversion and/or catalyst in the individual reactor.
  • first and/or second reactor may be operated in the temperature range 150-310°C, preferably 190-280°C and/or at pressure 50-150 kg/cm2 g, preferably 70-90 kg/cm2 g-
  • the first reactor and/or second reactor can depending on e.g. the type of reactors be operated with the same or dif- ferent catalyst. If the second reactor is an adiabatic re ⁇ actor it can be possible to utilize a more thermo-stable catalyst than used in the first reactor of a different type .
  • a purge can be taken preferably from the final recycle stream in order to avoid accumulation of inerts in the loop .
  • At least one compressor can be arranged in one or more of the unreacted streams such as in the first and/or second unreacted stream (recycle) . In case the methanol loop com ⁇ prises a third, fourth etc. set of Methanol reactor/ separator, a compressor may alternatively/also be arranged in one or more of the unreacted stream from these.
  • the present process and plant it is possible to increase the conversion of the CO and CO 2 per pass and in this way increasing the carbon efficiency and/or the synthesis loop recycle gas flow rate and thus improve the en ⁇ ergy efficiency and reduce the size of the recycle gas com ⁇ pressor .
  • the present process can be used in new methanol production plants, and it is also usable for revamping of existing plants comprising at least one Methanol loop in order to increase the capacity of such plants.
  • the present process and plant may be partic ⁇ ularly useful in relation to revamp projects. In many revamps of existing Methanol plants actions are taken to im ⁇ prove the module of the synthesis gas to the methanol reac ⁇ tor thereby increasing the molar weight of the recycle gas.
  • the capacity increase can be obtained by using the present process alone, or in combination with other revamp options.
  • the present process may be carried out in a plant compris ⁇ ing one or more Methanol loops wherein at least one of the methanol loops is arranged with two or more serially con ⁇ nected methanol with belonging separators for separating cooled reactor effluent into unreacted gas and raw metha ⁇ nol.
  • the plant may further comprise a compressor for the syngas entering the loop and one or more compressors ar ⁇ ranged in one or more of the unreacted streams.
  • the plant may comprise means for heating the streams before each reactor as well as coolers and condensers for condens ⁇ ing the effluent from each of the reactor before entering the subsequent separator.
  • the raw methanol streams, one from each separator may advantageously be collected into a collected raw methanol stream.
  • a schematic of the process and Methanol loop 1 is seen.
  • Recycle gas 2 and Make-up gas 3 is mixed to a mixed stream 4.

  • the effluent 5 from the first reactor is cooled in E1/E2, and most of the produced methanol is condensed and separated in a gas/liquid separator, VI.
