Upstream / Gas Field – Condensate Separator
RotaSep
® offers superior second-stage separation for upstream natural gas applications, extracting up to 5 times smaller particles in a much smaller, robust, and virtually
maintenance-free unit, resulting in higher operational efficiency.
- After natural gas is extracted from underground oil wells, it needs to undergo several separation stages to remove containments naturally occurring in the oil
reservoirs.
- Stage 1: large particles: The first stage consists of separating the large particles, such as mud and carbohydrates, from the gas stream. A generic separator is
mostly used for this purpose.
- Stage 2: fine containments: Next, a second separator focuses on removing the finer remaining liquid containments. These droplets are generally a combination of very
fine carbohydrates, oils, and water.
- Optimal separation performance is critical at this stage, as the natural gas will proceed to be transported through pipelines for processing. Any remaining
containments can cause damage to high pressure pipelines, resulting in high maintenance cost and downtime.
- With exceptional throughput and separation efficiency, RotaSep® is very well suited as second upstream separator. Thanks to its significantly smaller dimensions, it
fits any new or existing plant.
Downstream / Distribution – Pipeline Separator
RotaSep
® adds significant value as a downstream pipeline separator, with its exceptional separation performance in a unit that is 3 to 10 times smaller than comparable
installations, but without consumables or maintenance downtime.
- When high pressure gas transportation pipelines (operated at 40 to 100 bar) reach local distribution networks (operated at 8 to 20 bar), the gas pressure needs to be
reduced to meet local gas network standards through expansion.
- This expansion process leads to cooling and condensation, after which liquids need to be separated from the gas stream.
- If not done properly, liquids accumulating in the distribution pipelines can cause damage to the pipelines, resulting in high maintenance cost, downtime, and
potentially reduced quality of the natural gas at delivered to end-users.
- RotaSep® removes all contaminants (condensed water, oils etc.) from the gas distribution network.
- The RotaSep® unit is much smaller in size than traditional demisting vessels, its separation efficiency is up to 5 times higher and without annual filter replacement,
the maintenance downtime and cost is next to nothing with years of uninterrupted operation.
