Product Overview

The Kapwell Horizontal Degasser is the most effective and efficient meets the stringent requirement.

Kapwell supply customised CE marked ATEX Zone 1 certified vacuum degasser to suit the client requirements. All our components are NACE certified and manufactured to the highest quality.

Our degassers are designed to achieve an effective gas-liquid separation and ensure a smooth transition of vapour outlet. In the feedwater tank, the degassed water is collected. The gases can also be evacuated with the generated water vapour using a vacuum pump.

Our Horizontal degassers consist of ASME certified degasser vessel and control cabinet.

Safe Design

Design is the safest way to update values. This is due to highest specification.

High Operating Efficiency

Shell side baffles enabled a high level of operational efficiency while also allowing for manageable reductions in fluid pressure.

The Next Generation of Degassers

A highly experienced team of mechanical, process, and thermal design experts collaborated to optimise each and every aspect of Degasser designs for the next generation design.



Drilling Fluids hd

Drilling operations

During drilling operations, drilling fluids are used to cool and lubricate the drill bit, as well as to remove rock cuttings from the wellbore. These fluids are typically a mixture of water, oil, and various chemicals, including H2S scavengers. A horizontal degasser is used to remove any H2S that may be present in the fluids before they are re-circulated back into the well.

Oil and Gas Production

Oil and Gas Production

Horizontal degassers are also used in oil and gas production operations. When oil or gas is extracted from a well, it contains gas and other contaminants. These contaminants must be removed before the oil or gas can be transported and refined. A horizontal degasser can remove the gas and other contaminants from the extracted oil or gas, making it suitable for transport and refining.

Workover operations hd

Workover operations

Workover operations involve the maintenance and repair of existing wells. These operations may require the use of fluids that contain H2S, such as acidizing fluids or cementing fluids. A horizontal degasser can be used to remove the H2S from these fluids before they are used in the well.

Completion operations

After a well has been drilled, completion operations are conducted to prepare the well for production. This may involve the use of fluids such as brine, which can contain H2S. A horizontal degasser can be used to remove the H2S before the fluids are injected into the well.

Refining and Petrochemical Processing

Refining Operations

Horizontal degassers are used in refining operations to remove gas and other contaminants from crude oil. When crude oil is refined, it is heated to high temperatures, which causes it to release gas. This gas must be removed before the oil can be further refined. A horizontal degasser can remove the gas from the crude oil, making it suitable for further refining.


Petrochemical Industry

Horizontal degassers are also used in the petrochemical industry to remove gas and other contaminants from various chemical processes. These contaminants can be harmful to the equipment used in the chemical processes and can also affect the quality of the final products. A horizontal degasser can remove these contaminants, ensuring that the equipment remains safe and the final products are of high quality.
