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.

Although the urea market has weathered the pandemic relatively well, a significant amount of new capacity is due to come on-stream in the next year or so, and could keep prices depressed unless more Chinese capacity closes.

While the covid pandemic has kept refinery run rates down in 2020, new refinery sulphur capacity will nevertheless form the bulk of new additions to sulphur production over the next few years. But delays to projects on both the supply and demand sides could tip a fairly balanced market in either direction.

Metal processing in Northeast Asia is the major source of sulphuric acid exports from the region, and the ramp up of Chinese copper smelter capacity is leading to increased acid availability.

Calgary-based Pieridae Energy Ltd says that it has hired a new Chief Operating Officer as from April 5th. Darcy Reding is a professional engineer with 30 years of experience in small and medium-sized private and public upstream oil and gas companies, 20 years of that in leadership roles. Reding spent the last decade at NAL Resources as VP of Operations and VP Operations & Geoscience. Prior to NAL, Reding held technical and leadership roles with Norcen Energy, Northrock Resources, Samson Exploration and Enterra Energy Trust.

There is an old adage that if you put two economists in a room, you will get three different opinions. As the world enters its second year of dealing with the coronavirus pandemic, that certainly still seems to be the case among those grappling with predicting an increasingly uncertain world.

With declining ore grade feed to a metallurgical smelting process comes an increase in impurity load in the gas cleaning/acid process chain. K. Hasselwander, L. Skilling and C. Bartlett of Metso Outotec discuss a range of process solutions and how to maintain high productivity while keeping costs in check.

We report on the latest potash mining and processing technology from Andritz, Ebner, Köppern, K+S and Veolia. Recent case studies for potash projects globally are also provided.
