High energy storage costs for renewable-based technologies are likely to make European long term carbon prices considerably higher than their present levels.

While there is still a considerable push for use of biomass waste as a lower carbon feedstock for chemical production via gasification to syngas, biological processes such as fermentation are increasingly gaining traction as an alternative.

NextChem has been awarded two contracts to upgrade and expand the capacity of the Heydar Aliyev Oil Refinery (HAOR) industrial complex in Baku by state oil company SOCAR. As part of the contract, NextChem will conduct a technological assessment and deliver a process design package to upgrade the existing sulphur recovery unit (SRU) with oxygen enriched air, a cost-effective and flexible solution for expanding its current sulphur production capacity. Additionally, NextChem will provide the licensing and the process design package based on its proprietary NX SulphuRec TM technology for a new SRU. NX SulphuRec TM is a portfolio of proprietary sulphur recovery technologies, based on the integration of modified Claus and tail gas treatment processes, aimed at reducing the environmental impact of acid and sour gases produced during the refining process.

An ammonium nitrate industry geared around producing explosives for the mining sector is now being joined by a major urea project and a number of renewables-based products for export of green ammonia.

QatarEnergy has announced its decision to build a new, world-scale urea production complex that will more than double Qatar’s urea production. The project is aiming to construct three ammonia production lines which will supply four new world-scale urea production trains in Mesaieed Industrial City. Total capacity for the new complex is projected to be 6.4 million t/a, more than doubling Qatar’s annual urea production from about 6 million tons per annum currently to 12.4 million tons per annum. Production from the project’s first new urea train is expected before the end of this decade.

In spite of increasing environmental concerns over the use of coal as a feedstock, it continues to provide around one quarter of the world’s ammonia. But in a world that is decarbonising, is there still a future for coal-based capacity?

Urea revamp activities are performed to achieve improvements of the urea plant. Besides the typical capacity increase there are many options to reduce operation costs, increase plant availability or reduce environmental impact. In this article Marc Wieschalla of thyssenkrupp Uhde GmbH provides an overview of some of the options from an EPC contractor point of view.

With a large number of green ammonia projects under development, financing remains the greatest hurdle to getting ventures off the ground.

QatarEnergy has announced the construction of a new world-scale ammonia-urea production complex at Mesaieed Industrial City in Qatar.
