Germany: Mexico-based Cemex has joined a consortium with Sasol EcoFT and Enertrag that plans to use CO₂ and hydrogen to produce aviation fuel. The project is part of Cemex’s Future in Action program and is part of its plan to develop a carbon neutral operation at its Rüdersdorf cement plant by 2030. The consortium will source green hydrogen generated from wind and solar energy from Enertrag. The CO₂ will come from the Rüdersdorf cement plant, which will provide 100t/day CO₂ in the project’s initial stages. Sasol will then contribute its technology to produce e-kerosene, which, once certified, can be blended to constitute up to 50% of jet fuel.

The Rüdersdorf carbon neutral alliance includes over 20 start-ups, universities, companies from other industries and authorities working to develop industrial-scale solutions achieve the first carbon-neutral cement plant in the world.

Enertrag is a renewable-energy company based in Brandenburg. It operates utility-scale integrated energy plants in 10 countries. Its plants produce electricity and green hydrogen from wind and solar sources.

Sasol EcoFT is part of Sasol Group. It uses its technology to produce sustainable fuels and chemicals from green hydrogen and sustainable carbon sources, via the Power-to-Liquids process.

Taiwan: Ta-Ho Maritime has announced its decision to buy a new cement carrier. The subsidiary of Taiwan Cement said that the investment cost would be up to US$50m. The bulk shipping company transports dry bulk commodities around the world, including cement. Its fleet consists mostly of ‘Kamsarmax’ sized ships and cement carriers with a total deadweight upwards of about 700,000t. It operates five dedicated cement carriers, two of which use alternate maritime power (AMP) that are used to reduce pollution.

US: Titan America plans to spend around US$37m towards expanding its Norfolk terminal in Chesapeake, Virginia. The plans at the terminal, run by subsidiary Roanoke Cement Company, include building a 70,000t dome, enlarging truck and railway capacity and enabling the site to import and distribute raw materials such as fly ash, slag and aggregates. At present the unit has a bulk storage capacity of 35,000t. Titan says that the upgrade will enable it to meet growing demand for its products in the Mid-Atlantic region. The project also follows a similar investment in a 70,000t dome currently under construction at Titan's import terminal in Tampa, Florida.

"The major expansion and modernisation of these two marine terminals is another important step toward meeting fast-growing demand for our products and services in critical infrastructure, commercial and residential projects in our communities," said Bill Zarkalis, president and chief executive officer, Titan America.

The dome and associated expansion projects are scheduled for completion in 2023.

US: Switzerland-based Elex has completed a cold start-up of an electrostatic precipitator (ESP) it has supplied to National Cement’s Ragland plant in Alabama. The ESP will be used for primary dedusting and it has a separation area of approximately 7000m². The cement plant, owned by France-based Vicat, is currently building a new 5000t/day production line that is due to be commissioned in mid-2022.

India: Aumund Engineering India has been selected by ACC to refurbish a 175.3m high bucket elevator, the tallest in the world. The elevator is installed at ACC’s Wadi Cement plant in Karnataka where it is used for raw meal pre-heater transport at a rate of 600t/hr.

Originally, the machine was fitted with a steel cord belt of width 1320mm and tension rating of 3150N/mm. Aumund has decided to offer an alternative based on its own design concept resulting in a belt width of 1300mm but with higher tension rating of 4000N/mm with a bucket size of 1250mm at bucket spacing of 450mm. The Aumund belt concept will use continuous close pitch longitudinal ropes without rope free bucket mounting spaces. However, it will use additional wire ropes running laterally across the width of the belt adding lateral stiffness without significantly changing the belt longitudinal flexibility. This cross-stabilised construction is intended to improve stability to the belt with improved bucket fixing.

To make the necessary belt punching, Aumund has developed a special punching machine design which gives clean fixing holes that are accurately aligned relative to the belt edge and at precisely the correct pitch. The belt is held in a cassette and advanced automatically under the punching frame using a precision encoder to measure the pitch. The belts are prepared at the Aumund production in Rheinberg, Germany and shipped to site at the exact required dimensions including a prepared joint and the required clamping connection.

In addition to the new belt the elevator will also be fitted with new drive pulley including friction linings and rubber bucket mounting strips. The casings, inlet and outlet plus the complete drive unit remain unchanged.
No commissioning date for the project has been announced.
