SYSTEM AND PROCESS FOR THE PRODUCTION OF A SYNTHESIS GAS HAVING A LOW SPECIFIC H2/CO RATIO AND A LOW RESIDUAL METHANE CONTENT

摘要

A SYSTEM AND PROCESS FOR THE PRODUCTION OF SYNTHESIS GAS WITH A SPECIFIC H2CO RATIO, FOR EXAMPLE, 0.7 TO 1.2 AND A LOW RESIDUAL METHANE CONTENT, FOR EXAMPLE, LESS THAN 5 PERCENT (5 ). EXCESS HYDROGEN FROM THE SYNGAS FEED STREAM IS REMOVED BY A MEMBRANE (11) AS A PERMEATE (23) AND THE RETENTATE GAS (26) CRYOGENICALLY (13) SEPARATED. (FIGURE 1)
