Modularized System and Method for Urea Production Using Stranded Natural Gas

摘要

A modular system and method for producing urea from stranded natural gas includes 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 maintain a substantially homogenous mixture The resultant gas stream is further cleaned and compressed to a high pressure of about 3,000 psi. The resultant ammonia stream is processed in a bypass recycling loop system at 30% conversion rate at a high pressure of about 6,000 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 of a standard 48-foot flatbed trailer.

1. A method for producing a fertilizer or a fuel from a stranded natural gas feedstock, the method comprising the steps of:
i. capturing a natural gas feedstock that includes at least one stranded natural gas feedstock from at least one stranded natural gas source; ii. removing moisture from the captured natural gas feedstock; iii. removing potential disruptive inorganics and organics from the substantially moisture-free natural gas feedstock; iv. reformulating the substantially clean natural gas feedstock; v. recovering a CO2 stream from the reformulated natural gas feedstock; and vi. combining the recovered CO2 stream with a NH3 stream to form at least one of a fertilizer and a fuel.
