Portable MEG Reclamation Demonstration Plant

Portable MEG reclamation demonstration plant

Project: Portable MEG reclamation demonstration plant

Client: Leading global energy industry technology innovator

Background

Monoethylene glycol (MEG) is an important raw material for industrial applications and is widely used by the oil and gas industries as a reagent for hydrate inhibition in wellheads and pipelines. If recovered, regenerated and reinjected, it minimises both operating and environmental costs surrounding MEG disposal and replacement, which can save operators millions of dollars annually.

Strata was commissioned to design and supply a portable Dynamic Cross Flow Filtration (DCF) test unit to demonstrate and validate DCF for the removal of salts and other solids from rich MEG process streams. The demo unit needed to be fitted into a standard 20ft shipping container, fully certified for transportation and operation in hazardous areas. The minimum requirement to be met was Hazardous Area Class 1, Zone 2, IIA, T3.

Challenges

In April 2017, Strata began work on designing, assembling and supplying a containerised DCF test unit to the required DNV 2.7.2 standards.

One of the biggest challenges to overcome was understanding and implementing the design and build requirements under DNV 2.7.2 (Strata’s first project needing to meet these standards) and sourcing suitable equipment which would meet the ATEX requirement for the project.

Involving Strata staff across multiple departments and disciplines including projects, process, procurement, workshop, quality and Health & Safety, the successful delivery of this project required regular inter-department communication and teamwork.

Solutions

The team opened a dialogue with DNV and kept in regular contact to ensure the project was progressing per their standards, as well as obtaining DNV verification of proposed equipment documentation before any purchases were made. Keeping open communication channels with both DNV and the client throughout the life of the project was a key part of the successful delivery.

Speaking about the project, Dr Roger Kimber, Managing Director, Strata Technology said:

“The client’s support throughout the project over the past two years has been key in delivering this monumental project. The build of the Demo Plant brought new challenges to the business, ones which were fundamental to the delivery of the project and it’s fantastic to see how my staff have worked together to overcome the challenges we faced. We are very proud of the end result and look forwarding to seeing the Demo Plant go into action.”

Completion

The demo plant underwent successful (FAT) Factory Acceptance Testing and after trials at the customer’s own dedicated MEG reclamation R&D facility in the UK, the containerised unit will be shipped to Houston and deployed onto offshore drilling platforms in the Gulf of Mexico in November 2019.
