Molsieve-based Dehydration Technology - Frames · 2018. 7. 4. · [email protected]...

Product Definition

Frames Molsieve-based Dehydration Technology achieves very low

dew points for natural gas, associated gas and CO2. Our systems

allow you to efficiently remove water and hydrocarbons in order

to achieve clean gas streams ready for gas compression or even

liquefaction (LNG/LPG).

Product Description

The operation of demanding production systems strongly depends on

a continuous supply of clean gas with very low dew points. Compared

to common absorption (glycol) or low temperature separation (LTS)

technology, Frames Molsieve-based Dehydration Units can achieve dew

points as low as -80°C, and if required, right down to -100°C (<10ppm).

Full design service

At Frames, we are committed to optimizing system design, including

capital expenditure and operating expenses over the life of the

production facility.

Product Leaflet / p 1

Our team of engineers will design and commission

a cost-efficient gas drying system using molecular

sieves. However, selecting the best adsorbents is

only the first step in system design. Our in-house

experts deliver exceptional system performance by

working together with leading desiccant suppliers.

And to enhance performance and add further value,

we incorporate specific switching valves and use

heat conservation and energy-saving technologies.

Molsieve-based Dehydration Technology


Process Description

Feed gas enters the top of the Frames Dehydration Units and flows

downwards through a molsieve desiccant bed which removes the

water. The dried gas then exits at the bottom of the unit and is ready

for downstream processing.

Two-vessel system for peak performance

Frames Units typically use a multi vessel system with each vessel

automatically alternating between an adsorption and a regeneration

phase. The flow is automatically switched between the columns

to optimize system performance. Switching frequency is normally

determined by the required dew point and the selected desiccant, and

can either be time-based or dew point-based.

In the regeneration phase, the bed is first heated by a slipstream of

product gas to remove all water (and hydrocarbon) components. If

required, further heat can be supplied by an electrical heater or a

furnace. The dry adsorbent bed is then cooled by dry product gas and

is ready for re-use.

Dry versus wet regeneration gas

Adsorber regeneration can be achieved by using either dry or wet

gas. Dry gas is normally preferred when the adsorption system

must be maintained at a higher operating pressure. Because the dry

regeneration gas is extracted from the downstream process, the

adsorber capacity must be correspondingly increased. A compressor

may also be required to re-inject the dry gas into the system.

Wet gas regeneration gas has no impact on the system’s adsorption

capacity. The wet gas system does not require a compressor, typically

resulting in a relatively higher pressure drop. However, specific

measures must be taken to ensure safe and efficient cooling of the

adsorption beds.
