Methanol and Ammonia Production – process gas purification (Natural and Syngas)

RotaSep^® is a reliable and robust choice for liquid-gas separation applications for process gas purification, separating even the smallest particles to increase yield and stability, and prevent reactor fouling without annual filter replacements.

• Separation of liquids from the gas input stream in methanol and ammonia production installations is paramount. Containments could result in lower yields, more side reactions, lower catalyst lifespan and reduced stability of the entire plant.
• RotaSep^® offers an unprecedented separation efficiency at similar or higher throughput, but with a much smaller footprint than traditional solutions – making it a great fit with both new and existing installations. In terms of maintenance, RotaSep^®’s industrial build quality and internals without any consumables or replaceable filters makes it possible to operate for years without any downtime or costs.

Fertilizer Production – Sensitive Equipment Protection

RotaSep^® offers the best possible protection for sensitive equipment, such as CO₂ compressors in process gas applications, separating particles up to 5 times smaller than alternative solutions in a much smaller, lighter, and maintenance-free unit.

• Typically, the CO₂ compressor in a urea plant forms the bottleneck for higher plant loads - any improvement easily leads to increased profits for the operator.
• Generally, the suction and interstage separators applied in CO₂ compressors are not very effective in separating moisture, oil, methanol and washing fluids from the CO₂ desorber column in the ammonia plant.
• This causes fouling of the compressor internals, hydrogen converter catalyst and further downstream, resulting in reduced capacity, higher energy consumption, vibrations, higher pressure drops and expensive downtimes.
• Some plants perform online flushing procedures to solve these problems, risking side-effects like corrosion and vibrations.
• RotaSep^® makes it possible to have the best of both worlds, combining optimal impurity protection thanks to an exceptionally clean compressor, gas turbines and membranes input with uninterrupted, maintenance-free operation, as no annual filter replacement is necessary. With a significantly smaller footprint, RotaSep^® fits any new or existing plant.
