A modular system and method for producing urea from stranded natural gas incldes removal of foreign particulate matter to obtain a substantially homogeneous gas. The gas is processed by controlling the quality of the stranded natural gas to obtain a substantially homogeneous mixture. The resultant gas stream is further cleaned and compressed to a high pressure of about 3,000 psi. The resultant ammonia stream is processes in a bypass recycling loop system at 30% conversion rate at a high pressure of about 6,000 psi to 7,000 psi. The equipment associated with each of the process steps may be skid mounted for portability and/or contained within the footprint fo a standard 48-foot flatbed trailer.
