Building blocks for everyday life

Transforming natural gas

All of our products are derived from the conversion of natural gas feedstock. From humble beginnings, a 500,000 metric ton per year methanol plant, we have continually reinvested to develop our portfolio, which now includes anhydrous ammonia, urea ammonium nitrate and melamine. Today, Proman has an annual installed production capacity in excess of 10 million metric tons and we continue to grow, expanding into new markets and territories.

Methanol, anhydrous ammonia, urea ammonium nitrate and melamine are all crucial ingredients for the production of many everyday commercial, consumer and industrial products. Examples include automotive parts, paints, fertilizers, and fire-retardant coatings.

We are proud to be one of the leading partners for methanol in the world and one of the ten leading global fertilizer companies.


Methanol is a colorless liquid basic chemical and the starting point for the production of a multitude of everyday products like clothing, automotive parts, paints or building materials. Looking ahead, new applications for the use of methanol as a clean fuel are becoming more common - for example, in powering marine vessels.

Trinidad Plant Proman

In our production facilities in Trinidad and Tobago and the United States, methanol is made from natural gas and water. These are combined, heated and passed over a catalyst to produce a mixture called synthesis gas. Using a further catalyst, the synthesis gas is reacted to become methanol which is finally distilled to make the pure product. Proman has a total annual installed production capacity of approximately 7 million metric tons globally.

Nitrogen is an essential nutrient for healthy plant growth and high crop yields, and as such, nitrogen-based fertilizers play a significant role in the global agricultural industry.

We have a total annual installed production capacity of approximately 2 million metric tons of ammonia, which is the most common source of nitrogen content in fertilizers and a base chemical for a vast range of nitrogenous compounds. Ammonia has also found use in pollution control applications such as selective catalytic reduction (SCR) of nitrogen oxides (NOx) levels in motor vehicle exhausts.

We also produce urea ammonium nitrate (UAN), a liquid nitrogen-based fertilizer. Solutions containing UAN are very versatile as a source of plant nutrition. Due to its chemical properties, UAN can be combined with other nutrients or chemicals. Therefore, the liquid fertilizer can be customized to meet the needs of a soil or crop.

Our annual installed production capacity for UAN is 1.5 million metric tons.

The intermediate product, urea, is also used to manufacture melamine. Melamine is a white, organic, crystalline chemical used, for example, in the production of plastics and kitchen surfaces. Our two melamine plants have a total installed production capacity of 60,000 metric tons.


Melamine formaldehyde resins show excellent fire-retardant properties. When burned, nitrogen is released which inhibits the combustion.
