New innovations, services and latest technologies to improve the operation and reliability of steam methane reformers from AMETEK Land, Kontrolltechnik, BD Energy Systems, Koch Engineered Solutions, and Quest integrity.
Ricardo L. Sepulveda of PegasusTSI reviews options to decrease the CO2 footprint of a fertilizer industrial complex and illustrates the technical and economic feasibility of utilising clean energy from a sulphuric acid plant in a fertilizer complex to produce green hydrogen, which in turn can be used to produce green methanol or green ammonia.
The production of syngas from hydrocarbon feedstock uses a number of catalytic steps to increase efficiency and maximise conversion while minimising energy consumption. In this article we report on the latest developments in water gas shift catalysis from Johnson Matthey, Clariant and Topsoe, and shift converter design from Casale.
As a quick glance through the Index of last year’s articles and news items in this issue of the magazine will amply demonstrate, 2021 was a year full of project announcements for low carbon ammonia and methanol projects of all hues; blue, green, turquoise and many other shades besides. Market analysts CRU said in December that they calculated that there have been a total of 124 million t/a of low carbon ammonia projects announced, 80 million t/a of which came in 2021 alone, equivalent to 55% of current ammonia capacity. These range from tentative pilot plants that are fully costed and often with government grants already secured to blue sky visions of vast electrolysis hubs in the deserts of Arabia with timescales towards the end of the decade – it’s often the case that the longer the proposed timescale, the less likely a project is to happen.
The ammonia market has entered 2022 looking very different to last year, with early January Pivdenny prices $875/t higher on a mid-point basis than they were at the start of 2021, and the likelihood of further gains ahead.
The Bia Energy Operating Company says that it is evaluating a $550 million blue methanol plant at the port of Caddo-Bossier in Shreveport, Louisiana. The unit would have a capacity of 530,000 t/a of methanol using natural gas feedstock with downstream carbon capture, reducing CO2 emissions by more than 90% compared to other methanol plants. The company is expected to make a final decision in 1Q 2022, with construction expected to last approximately two years, and commercial operations to begin soon after.
As the world looks to a lower carbon future, refineries are having to examine their operating models, and look to, for example, renewable hydrogen production for desulphurisation technologies.
Topsoe has begun operations at a demonstration plant for the production of methanol from biogas. The aim is to validate the company’s electrified technology for cost-competitive production of sustainable methanol from biogas as well as other products. The project is supported by the EUDP Energy Technology Development and Demonstration Program and is developed together with Aarhus University, Sintex A/S, Blue World Technology, Technical University of Denmark, Energinet A/S, Aalborg University, and Plan-Energi. The demonstration plant is located at Aarhus University’s research facility in Foulum, and will have an annual capacity of 7.9 t/a of CO 2 -neutral methanol from biogas and green power and is scheduled to be fully operational by the beginning of 2022. It uses Topsoe’s eSMR ™ technology, which is CO 2 -neutral when based on biogas as feedstock and green electricity for heating. It also uses half the CO 2 that makes up about 40% of biogas and typically is costly to separate and vent in production of grid quality biogas.
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.
