Optimising European SRU incinerators

The 2030 greenhouse gas emission reduction goals in the European Union are driving oil and gas producers to reduce CO2 emissions wherever possible. This extends to even the incinerator attached to a sulphur recovery unit (SRU). In this article Sulphur Experts review the role of the incinerator, how the three most common European TGUs each affect the demand on the incinerator itself, and the potential reduction in CO2 emissions for a generic facility of each type.

Channelling in SRU converters

This troubleshooting case study describes an incident at one of the sulphur recovery units at BPCL Kochi Refinery, India. Following a maintenance turnaround of the unit in 2022, unusually high H2 S and SO2 were observed at the outlet of the Claus section. This created an additional load on the tail gas reactor, which led to frequent plugging in the quench column and frequent outages in the tail gas unit, creating environmental and reliability issues in the unit. The activities to identify the root cause of the incident are described and the measures to solve the problem are shared.

Price Trends

At the end of August, the Qatar Chemical and Petrochemical Marketing and Distribution Company (Muntajat) tendered for 35,000 tonnes of sulphur for September loading from Ras Laffan, with offer prices reported at or around $130s/t f.o.b., according to market sources. Bids were received at multiple levels, with market participants initially anticipating awards around the mid-$120s/t f.o.b. The tender result was higher than market expectations and would equate to delivered prices to key Asian markets at $150-155/t c.fr. But prices in China and Indonesia remained lower this week at around $140-145/t c.fr, with India at $145-150/t c.fr. Prices have increased steeply since Muntajat’s 25 June session, which was indicated awarded in the mid-$80s/t f.o.b.. and Muntajat posted its Qatar Sulphur Price (QSP) for September at $125/t f.o.b., up $19/t from $106/t f.o.b. in August. This represents the highest QSP since March 2023 at $133/t f.o.b., and reflects delivered levels to China nearing $150/t c.fr at current freight rates. Tight supply and strong downstream demand have pushed tender prices higher. Muntajat tenders were previously awarded at $92/t f.o.b. in April, up from $88/t in March and the low $80s/t f.o.b. in February.

Sulphur Industry News Roundup

Shell Deutschland has taken a final investment decision (FID) to progress REFHYNE II, a 100 MW renewable proton-exchange membrane (PEM) hydrogen electrolyser at the Shell Energy and Chemicals Park Rheinland in Germany. Using renewable electricity, REFHYNE II is expected to produce up to 44 t/d of renewable hydrogen to partially decarbonise site operations. The electrolyser is scheduled to begin operating in 2027. Renewable hydrogen from REFHYNE II will be used at the Shell Energy and Chemicals Park to produce energy products such as transport fuels with a lower carbon intensity. Using renewable hydrogen at Shell Rheinland will help to further reduce Scope 1 and 2 emissions at the facility. In the longer term, renewable hydrogen from REFHYNE II could be directly supplied to help lower industrial emissions in the region as customer demand evolves.
