UniverSUL Consulting

Remove all doubt

We are a unique owner’s engineering firm made up of a collective of sour gas and sulphur technology experts who provide specialized, technology-neutral expertise.

Sulphur processing plant

We started UniverSUL Consulting in 2014 in Abu Dhabi, UAE, where some of the world’s largest sour oil and gas projects are taking place. Our team of hand-picked consultants has the depth and breadth to address any of your sulphur-related challenges, whether they be related to process, mechanical, layout, constructability and/or plant operations.

But it’s not just our work experience that makes us recognized as the industry’s most trusted experts – it’s also the fact that we are technology neutral. Because we do not sell technology, there is no incentive for us to recommend one process over another unless it provides true technical or commercial advantages. When we say something is the best fit for your business, you can take our word for it – we stake our reputation on it.

In addition to our technical expertise, we are truly effective communicators who regularly engage with the global sulphur community. Our relationships and communication skills make it possible for us to facilitate effective information and knowledge transfer between you and your technology providers and contractors; the result is increased productivity, less rework and ultimately lower risk. When you take us on as a partner, you can rest assured that our primary objective is to help you remove all doubt that your facilities can be developed and operated safely, efficiently and at lowest lifecycle cost.   

Our Services & Areas of Expertise

Let's get to work

From H2S removal to elemental sulphur production, degassing, forming, handling and transportation, our team can help you navigate the landscape of available process and technology options and select the alternatives that are best suited to meet your objectives.

Gas Sweetening & Acid Gas Enrichment

Whether it’s generic or formulated amines, hybrid or physical solvents, we can help you select the most beneficial option through comprehensive net present cost analyses, including consideration for optimization measures such as integration of the gas sweetening unit with the downstream sulphur recovery facilities.

Sulphur Recovery

While many sulphur recovery facilities appear to be the same, key differences exist that create unique, often critical design concerns for the plant. We can help you determine the most practical and effective means of tackling various challenges such as lean acid gas processing, contaminant destruction and revamps to address requirements for increasing capacity or recovery efficiency in existing facilities.

Tail Gas Treating

The goal of sulphur plant tail gas treating is to comply with SO2 emission regulations, while also minimizing net present cost. Of the various technology possibilities such as sub-dewpoint Claus, tail gas direct-oxidation or amine-based tail gas treating for absorption of H2S or SO2, we can help you select and implement the most cost effective option that will allow operation safely inside permit limits.

Sulphur Degassing

Due to its toxic and explosive nature, removal of H2S from Claus-produced sulphur is essential to accommodate safe handling in downstream facilities. We have experience with all types of sulphur degassing processes and technologies including in-pit, external and elevated pressure systems, and can help you determine the right choice for you, based on process performance, off-gas disposal requirements, plot constraints and cost.

Sulphur Product

While elemental sulphur is a byproduct of oil and gas processing, it is also the primary raw feedstock for the production of sulphuric acid, one of the world’s most important chemicals. We can help you select and implement proper forming, handling and transportation design elements, throughout every step of the value chain, from production to consumer, ensuring that premium product arrives safely in the end-user’s custody.

Sour Water Stripping

Various sour water streams produced in oil and gas processing facilities must be treated to remove H2S and NH3 prior to discharge. Although sour water stripping is primarily an open-art endeavor, experience and know-how are essential to ensure robust operation and long plant life. Our experience can be leveraged to provide you with the tools you need to manage sour water streams in your facility safely, effectively and economically.
