Gordon Feller looks at Gasunie’s plans to build a new nitrogen plant at Zuidbroek to allow for the progressive shutdown of the Groningen gas field, one of the largest in Europe.

Recent spikes in natural gas prices, particularly in Europe, have highlighted the tightness of natural gas markets around the world going into the northern hemisphere winter. Are ammonia and methanol producers on for a run of high gas prices in 2022?

Last year the International Energy Agency (IEA), in conjunction with IFA, published the Ammonia Technology Roadmap, which looks at ways of achieving decarbonisation of the nitrogen fertilizer industry by 2050. In this article we look at the scenarios and technology options that will define the industry over the next three decades.

Stamicarbon offers advanced scrubbing technologies for fertilizer granulation plants and prilling towers. This article describes the technology and experience with the second operational MMV scrubber, which is installed at the Dakota Gasification Company’s (DGC) urea granulation plant, and highlights the successful pilot test with its JV scrubbing technology.

With globalisation seemingly in retreat, the protectionist impulse is seeing a rise in barriers to trade, from quotas and tariffs to anti-dumping actions and domestic subsidies.

A move towards smaller scale feedstocks such as renewable energy and waste and biomass gasification is leading to increased focus on improving the efficiency of small-scale, modular plants.

Reducing carbon footprint in the synthesis of chemicals is a new challenge, a necessary requirement in the pursuit of sustainable products designed to minimise environmental impacts during their whole lifecycle. So-called “green” technologies for ammonia, methanol and hydrogen are being developed to meet these challenges. Casale, Linde, thyssenkrupp Industrial Solutions, Toyo Engineering Corporation, Haldor Topsoe and Stamicarbon report on some of their latest developments.

A detailed rain and wastewater concept is an important part of a urea plant to meet current stringent environmental standards. Wastewater can originate from the process reaction or from outside the process equipment. In order to optimise the wastewater system of a urea plant, both the amount and type of contamination need to be known. With this knowledge, non-contaminated rainwater as well as process drains can be kept separate as much as possible to minimise the amount of wastewater to be treated, saving costs and energy. Wastewater treatment concepts from thyssenkrupp Industrial Solutions and Toyo Engineering Corporation are described.

Scanfeld™ is the world’s first remote sensing solution for fully automated early-warning gas leak detection for chemical plants. Using FTIR spectroscopy, Scanfeld™ identifies hundreds of different gases in real time from kilometres away. With just a few Scanfeld™ sensor units, large production sites, tank farms, or gas loading areas can be monitored reliably. Gas leaks are quickly detected, and the formation of dangerous gas clouds is monitored, measured, and visualised. René Braun of Grandperspective discusses how the system works and how it is being applied in industry.

In China, requirements for methanol to produce olefins, mainly propylene and ethylene, from coal, has driven much of the growth in global methanol demand over the past decade. However, a new wave of ethylene cracker investment may put a stop to new MTO plant building.
