More than 70 loop reactors are in operation for the production of fatty acids and derivatives with batch capacities of 1 to 50 tonnes. The HH Loop Reactor is the core for all of the following fatty acid derivatives processes.
chart fatty acids fatty amines nitriles

NOTE: partial and full saturation of oil and fats. The loop reactor was adopted due to its simplicity in changing products from batch to batch, batch flexibility, high yields, reduced nickel content in the final product, suitability for ruthenium catalyst, selectivity, highest batches per day capacity, heat recovery and steam generation, high safety standards and reproducibility.
