Abstract

The decline in the pressures of natural gas wells is forcing industries to either find more sustainable alternatives or temporarily make up for the shortfall. One such Pakistani gas field is the Mari Gas Field reservoir, from which the natural gas is extracted and used to produce ammonia which is the precursor of urea production. To temporarily cope with the declining pressures, this study proposes that a mixture of exported RLNG (30%) and Mari gas (70%) be used as feed. Material and Energy balances and the reactor designs were carried out and compared with the existing feed. Results showed that the proposed blend of RLNG and Mari gas could be used for ammonia production. However, alterations in the form of increased tube lengths, reactor volumes, and catalyst loading will be required in the main equipment of plants. Nevertheless, these modifications result in 20784-20791a +20.65% increase in hydrogen production, +4.53% increase in ammonia production, and +4.54% increase in urea production. Thus the proposed scheme can be adopted to manage the shortfall of Mari gas.
