Commodity markets are often volatile, and sulphur and sulphuric acid can be more so than most, with much of their supply coming from involuntary production, and sulphur supply in particular often dependent on the timing of large scale oil and gas projects. Even so, this year’s price rises, in some cases tripling in just over a year, have been especially eye-catching.
The continuing spread of alkylation technology and the preference for the sulphuric acid route are leading to increased demand for acid in refineries.
Sulphur processing and handling equipment manufacturer IPCO has completed the commissioning of a groundbreaking new drum granulator in Italy that will serve as a global showcase for this patented system. C. Metheral of IPCO, describes the innovative approach and key features of the SG20 sulphur granulation system.
Developments in sulphuric acid technology and engineering know-how are highlighted by recent project case studies from DuPont Clean Technologies, Metso Outotec and thyssenkrupp Uhde.
What lessons can be learnt from the successful commissioning and start-up of major fertilizer industry construction projects? Recent case studies from the nitrogen, phosphate and potash industries provide some interesting answers.
Magnesium, a key constituent of chlorophyll, plays a vital role in plant photosynthesis and carbohydrate production. Commercial sources of this essential crop nutrient include Epsom salt, kieserite, langbeinite, magnesium chloride and magnesium nitrate.
We compare and contrast the 2020 financial performance of selected major fertilizer producers, following the publication of fourth-quarter results.
Vacuum filtration is a key process step in phosphoric acid production. We highlight the main equipment options and recent project installations.
Maya Rehill of Anglo American Crop Nutrients discusses the latest crop trial findings for the polyhalite product POLY4 with the company’s regional agronomists. These highly positive trial results add to an already extensive evidence base on POLY4’s crop benefits.
A recent report from BloombergNEF (New Energy Foundation) looking ahead to 2050 argues that green hydrogen can be cheaper than natural gas. It finds that ‘green’ hydrogen from renewables should become cheaper than natural gas (on an energy-equivalent basis) by 2050 in 15 of the 28 markets modelled, assuming scale-up continues. These countries accounted for one-third of global GDP in 2019. In all of the markets BNEF modelled, ‘green’ hydrogen should also become cheaper than both ‘blue’ hydrogen (from fossil fuels with carbon capture and storage – CCS) and even ‘grey’ hydrogen from fossil fuels without CCS. The cost of producing ‘green’ hydrogen from renewable electricity should fall by up to 85% from today to 2050, the report predicts, leading to costs below $1/kg ($7.4/MMBtu) by 2050 in most markets. These costs are 13% lower than BNEF’s previous 2030 forecast and 17% lower than their previous 2050 forecast. Falling costs of solar photovoltaic (PV) electricity are the key driver behind the reduction; BNEF now believes that PV electricity will be 40% cheaper in 2050 than they had thought just two years ago, driven by more automatic manufacturing, less silicon and silver consumption, higher photovoltaic efficiency of solar cells, and greater yields using bifacial panels.
