Southeast Asia has been a major site for new syngas projects in recent years as countries such as Indonesia, Malaysia and Brunei continue to monetise their natural gas resources.

Methanex has said that, in light of the uncertainty in the global economy from the Covid-19 pandemic, it will defer approximately $500 million of previously announced capital spending on its $1.4 billion Geismar 3 methanol project for up to 18 months. Geismar 3, which is intended to eventually produce 1.8 million t/a of methanol, will be placed on temporary “care and maintenance” for up to 18 months, enabling the company to complete the project when market conditions improve. Methanex says it will spend $100 million in Q1 2020 and a further $200 million from April 1, 2020 to September 30, 2021 on the project, the majority of which is spending that occurred or was committed during Q1 2020. This is approximately $500 million lower than the $800 million that was expected to be spent over that same period. Construction activity and procurement of non-critical equipment and bulk materials will be suspended until market conditions allow the Geismar 3 project to restart.

Imagine an industry that only uses carbon-free fuels and does not have any carbon footprint. Assume this is feasible within a decade. Now wouldn’t that be an ambition worth pursuing? Duiker believes this is achievable. A. Lanser provides Duiker’s view on how its SCO technology can act as an enhancer for reducing industrial carbon footprint.

Olefins production from methanol, particularly in China, has come to dominate the methanol market over the past few years. However, environmental and market concerns complicate the outlook there.

A Stamicarbon urea plant attempts to start up after a scheduled turnaround. Due to maintenance issues, it is necessary to shut down and block in the synthesis section several times. Although licensor’s procedures have been followed, several signs of active corrosion are noticed in the liner of the reactor. What could the cause be for this unexpected behaviour? Can sharing experiences from colleagues from other urea plants provide valuable support to find the root cause or even provide new insights into possible new causes? One observation is that the typical heating up rate of a liner in a reactor is much higher than recommended (refer to diagram). The condensation heat of steam heats up the liner much faster than the carbon steel pressure bearing wall. This creates stress on the liner and affects the lifetime of the liner. Another observation is a temperature rise in the reactor during a blocking in situation. This can be a cause for loss of oxygen required for passivation, resulting in higher corrosion rates.

As existing facilities grow older, service requirements increase. Equipment needs to be low maintenance and back in operation quickly after service and repair. Technology licensors are expanding their technical services with new digital tools, using digitalised expertise with real time insights and data driven analytics to boost chemical production and ensure that equipment operates reliably and efficiently, while maintaining product quality.

The devastating effects of the Covid-19 pandemic continue to be felt around the world. At time of writing, nearly 4 million cases have been recorded, and at least a quarter of a million people have died, with the suspicion of many more, either from accidental or deliberate undercounting. Figures for excess deaths above a normal seasonal baseline show that places such as Turkey, Ecuador and Indonesia have probably been far worse affected than the official statistics show. There are nevertheless finally hopeful signs that Europe, so far the worst affected region, is beginning to follow the pattern of East Asia and Oceania and that cases are falling. The infection also seems to have peaked in North America, though in the US there is a long tail of infections. Elsewhere, cases are still rising in countries such as Brazil and Mexico.

Alistair Wallace, Head of Fertilizer Research, Argus Media, assesses price trends and the market outlook for nitrogen.

Paving the way for commercially attractive, sustainable, decarbonised fertilizer production, J. Dobrée of Stamicarbon BV discusses the latest developments for nitrate fertilizer production based on renewable feedstocks sourced from solar and wind energy. Stamicarbon has upgraded plant designs used in the past to create a new type of small-scale fertilizer plant capable of producing a product mix that can be adjusted to meet specific local requirements with maximised output value, thereby maintaining a competitive position towards imported products and large-scale producers.

Nitrogen+Syngas’s annual listing of new ammonia, urea, nitric acid and ammonium nitrate plants shows that the key areas for new project developments are Egypt, India, Nigeria and Russia.
