Successful start-up of LAMINOL sulfur removal and recovery unit for Antwerp refinery

November 23/2020

MOSCOW (MRC) -- Frames has supplied, and successfully commissioned, a hydrogen sulfide (H2S) removal unit, based on Frames’ proprietary LAMINOL technology, to a refinery in Antwerp, Belgium, said Canplastics.

With significantly lower cost of ownership than conventional caustic scrubbers and solid bed type H2S removal processes, the LAMINOL process is suitable for low to mid sulfur loads. Researching the most effective solution to comply with the refinery’s stringent flue gas SOX emission limits, various technologies were evaluated during the conceptual design phase, including flue gas treatment and caustic scrubbers. Frames’ LAMINOL technology was selected as most effective, while meeting the refinery’s total cost of ownership requirements. Working to a fast track schedule, the modular H2S removal system was quickly installed and commissioned.

Instead of treating the flue gas directly, the LAMINOL technology removes sulfur components from the distillation overhead gas containing up to 60% H2S before it is combusted in the process furnace. Treating the waste gas in a stand-alone modularized unit meant that the unit was much easier to integrate into the existing refinery facility. The gaseous sulfur removed is converted into elementary sulfur in solid form.

“LAMINOL is a highly effective, and economically attractive, method for deep H2S removal at high concentrations,” says Lennard Spit, gas treatment specialist, Frames. “And unlike many other removal systems, the technology is robust and capable of infinite turndown and handling feed gas fluctuations that are more representative of ‘real world’ refinery waste streams."

Frames LAMINOL technology is the result of an in-house R&D program initially developed and applied in the biogas market where it provides a cost-effective alternative to conventional biogas sweetening processes. The LAMINOL technology is capable of selectively removing H2S from CO2 rich gas streams to a few ppm even at near atmospheric gas pressure and is suitable for treating any gas stream.

As MRC informed previously, global oil demand may have already peaked, according to BP's latest long-term energy outlook, as the COVID-19 pandemic kicks the world economy onto a weaker growth trajectory and accelerates the shift to cleaner fuels.

Earlier this year, BP said the deadly coronavirus outbreak could cut global oil demand growth by 40 per cent in 2020, putting pressure on Opec producers and Russia to curb supplies to keep prices in check.

And in September 2019, six world's major petrochemical companies in Flanders, Belgium, North Rhine-Westphalia, Germany, and the Netherlands (Trilateral Region) announced the creation of a consortium to jointly investigate how naphtha or gas steam crackers could be operated using renewable electricity instead of fossil fuels. The Cracker of the Future consortium, which includes BASF, Borealis, BP, LyondellBasell, SABIC and Total, aims to produce base chemicals while also significantly reducing carbon emissions. The companies agreed to invest in R&D and knowledge sharing as they assess the possibility of transitioning their base chemical production to renewable electricity.

Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).

According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,594,510 tonnes in the first nine months of 2020, up by 1% year on year. Only high denstiy polyethylene (HDPE) shipments increased. At the same time, PP shipments to the Russian market reached 880,130 tonnes in the nine months of 2020 (calculated using the formula: production minus exports plus imports, exluding producers' inventories as of 1 January, 2020). Supply increased exclusively of PP random copolymer.
