Natural Gas Condensate RPS-demister

Natural Gas Condensate RPS-demister

Enexis, a gas provider in the Netherlands, is equipped with a RPS-demister for condensate removal at a gas distribution station. The RPS handles the full gas flow of the station(16,000 Nm3hr-1, 8 bar, -15 °C) (14 MMSCFD, 120 PSI, 5 °F).

Filter Element of the RPS

Filter Element of the RPS

The filter/coalescing element consists of a large number of axially oriented channels. Channels can range from stainless steel tubes to plastic straws

Industrial RPS-deduster

Industrial RPS-deduster

The all stainless-steel RPS-deduster is developed for ash removal from hot flue gas of combustion installations and for product recovery in pharmaceutical and food industry. For these applications the RPS-deduster is equipped with an integrated dust removal system

On-Site Demonstration RPS-demister

Multi purpose demonstration unit presented on the left with computer aided design shown on the right. The unit which can handle 2400 Nm3hr-1 at 8 bar and 20 °C (2 MMSCFD, 120 PSI, 70 °F) was tested at Eindhoven University with water and air. The unit features an optional drive with magnetic coupling. The performance was according to design specifications. The unit was subsequently installed in a slip stream of an Enexis gas reduction station and operated for a year without difficulty.

It is operated with water and air under ambient conditions to investigate high liquid loading and separation performance under semi-turbulent conditions in the rotating element. The flow is equivalent to a natural gas flow of 100,000 Nm3hr-1 at 8 bar, 20 °C (80MMSCFD, 580 PSI, 70 °F). Performance was found to be according to expectations.

Low Temperature RPS-demister in CRS Test Loop

Low Temperature RPS-demister in CRS Test Loop

Proof of principle of the CRS process was executed at Shell Global Solutions in Amsterdam. As part of the lab-scale plant a RPS-demister was built which handles 60 Nm3hr-1 at 30 bar, -50 °C (0.05 MMSCFD, 435 PSI, -58 °F). The unit is fabricated from duplex steel and features ceramic bearings and a magnetic coupling of the drive.

Two-Step CRS

Two-Step CRS

The two-step CRS process operates at two different temperatures and pressures including an internal loop. It results in maximum purities of the gas and liquid streams at the exits.

Upgrading Sour Gas by CRS

Upgrading Sour Gas by CRS

Shown on scale is a design schematic of a plant based on the two-step CRS process to upgrade natural gas contaminated with 27% H2S and 14% CO2. The plant can handle 100 MMSCFD (124.000 Nm3hr-1 ) which is typical for medium sized gas fields. Compared to conventional methods of Amine scrubbing and Cryogenic Distillation the plant is 100 times smaller in volume. It can be further reduced in size by applying plate heat exchangers. CRS-based plants cost less and consume little energy despite high H

Carbon Capture by CRS

Carbon Capture by CRS

Shown is a CRS based process to separate and liquefy the greenhouse gas CO2 from flue gases. The two step CRS process is suited for flue gases with CO2 concentrations >50% encountered among others in oxy-coal power plants and several industrial processes. Compared to conventional condensation methods, installations based on CRS are small in size and cost less. They can recover up to 98% of the CO2 of the feed in the form of a liquid of purity of up to 99%, all this at lowest energy penalty.
