Modularized system and method for urea production using a bio-mass feedstock

A method for producing urea from bio-mass, the method comprising the steps of:

• (i) cleaning a bio-mass feedstock to remove non-organic matter, the cleaned bio-mass feedstock including no more than 1% non-organic matter by weight;
• (ii) blending the cleaned bio-mass feedstock to obtain a homogeneous blend;
• (iii) pelletizing the blended bio-mass feedstock to a substantially uniform size;
• (iv) pulverizing the pellets to a fine particle size of 1 mm or less;
• (v) gasifying the pulverized pellets in a gasifier to create a syngas stream while maintaining a constant temperature of the gasifier within ±25° C.;
• (vi) removing a CO2 stream from the syngas stream;
• (vii) compressing the CO2 stream to a pressure no less than 6,000 psi and no greater than 7,000 psi;
• (viii) providing an NH3 stream in a bypass recycling loop at 30% conversion and a pressure no less than 6,000 psi and no greater than 7,000 psi;
• and
• (ix) combining the compressed CO2 stream with the compressed NH3 stream to form urea.
