More than 80% of the world's sulphur (some 40,000,000 tonnes per year) comes as a by-product in the refining of oil and gas. The sulphur is removed as a molten liquid, and then must be processed into a solid form that can be handled both safely and responsibly.
Today's sulphur forming processes can be divided into two categories: premium (GX granulation) and non-premium (wet prilling and slating).
We have experience in designing and operating versions of all of the forming processes being used commercially today, as well as our own patented GX™ granulation system, the industry's process of choice.
We also look to our own Canadian sulphur forming and handling operations for technical field support and assistance in process development. This means that we are running your equipment in our own plants.
In response to the need for a new generation of formed sulphur to meet the increasingly stringent standards imposed by both environmental considerations and customer preference, Enersul developed and successfully commercialized the sulphur forming process known as the GX™ granulating process. The GXM1™ has a design forming capacity of 1250 metric tonnes per day. It's the choice of producers who want to form large quantities of premium sulphur granules to supply the international market.
It's completely self-contained: a compact design with a rotating drum, a cooling water system, a wet scrubber, vibrating screens and conveyors.
The GXM1™ equipment is in a class by itself. Operation is simple, so on-time performance is high, labour requirements are minimal, and costs for repair, maintenance and utility consumption are kept low.
The GXM3™ is the first - and only - portable sulphur forming unit on the market. Its patent pending technology was developed for use on sites with smaller plant footprint spaces, for clients that want shorter start-up times, and/or require smaller production rates.
The GXM3™ arrives 90 per cent assembled, with most of the system checks already completed, thus saving on construction and commissioning time and costs.
Each unit can produce up to 400 metric tonnes of high quality granules per day. If greater capacity is required, two or more units can be attached together on common walkways so operators can move freely from one to the other, without constructing additional expensive walkway systems.
The GXM3™ is designed according to the same principles of safety and environmental responsibility as others in Enersul’s GX™ series of granulators, a series that has been the standard-setter in the worldwide sulphur forming industry for more than 30 years. Just another way Enersul has found a solution for the sulphur market,
The Enersul WetPrill™ sulphur forming process has been a staple in Canadian operations since 1978. The process has been continually improved using in-plant operational development and a research pilot plant. Enersul's patented WetPrill™ process is used in sulphur facilities around the world.
In the WetPrill™ process, molten sulphur is pumped onto perforated trays that direct the sulphur in narrow streams into an agitated water bath. Pellets form as the sulphur comes in contact with the water. The low thermal conductivity, high specific heat, and long transformation time of sulphur make it necessary to maintain the pellets in suspension for as long as possible, allowing them to harden. This process produces spherical, uniformly sized, low moisture pellets.
The standard Enersul WetPrill™ unit produces 1000 tonnes per day, however the unit can be sized to produced a range of 500 - 2500TPD. Higher throughput can be achieved with multiple process lines.
