Lehigh Cement’s Picton plant to use alternative fuels

01 September 2022

Canada: Lehigh Cement has initiated the administrative process to begin the use of alternative fuels (AF) in cement production at its Picton cement plant in Ontario. Under the company’s plans, the plant will substitute 200t/day of AF for coal and petcoke at the plant. Possible AF sources include excess seed from farm feed production in Ontario. The Picton cement plant previously reduced its CO2 emissions per tonne of cement by 20% through assorted sustainability initiatives.

Picton plant manager Carsten Schraeder said that the move will support Canada’s 2030 emission reduction plan, and also take pressure off landfill sites.

Ssangyong Cement orders equipment from KHD for Donghae plant

31 August 2022

South Korea: Ssangyong Cement has ordered equipment from Germany-based KHD Humboldt Wedag as part of an upgrade to clinker production line five of the Donghae plant. The scope of supply for the contract includes: a Pyroclon R type calciner with Pyrotop mixing chamber; a Pyrorotor type alternative fuel combustion reactor; a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage four cyclones with new high-efficiency cyclones for calciner connection and an overall pressure drop reduction; a new kiln inlet chamber with orifice, kiln hood and tertiary air ducts; and a new Pyrofloor PFC 738AW type cooler with a Pyrocrusher PRC 420-4ES.

This project will be the fourth Pyrorotor installation at the Donghae plant. KHD’s scope includes the engineering and supply of mechanical equipment for the clinker production as well as electrical equipment for the overall modernisation of the production process. The project scope is the same as the modernisation contract of line four of Donghae plant, which was signed in February 2021 and currently is in commissioning. The commissioning of the modernised line five is scheduled for the fourth quarter of 2023.

Cemex to use hydrogen technology at cement plant in Dominican Republic

30 August 2022

Dominican Republic: Cemex says it is planning to start using hydrogen technology at its integrated San Pedro De Macoris cement plant. It inaugurated the project during a visit by chief executive officer Fernando A Gonzalez. It is part of the company's Future in Action program that seeks to achieve carbon neutrality by 2050.

The group currently uses the technology by injecting hydrogen into cement plant kilns to optimise the combustion process and to increase the use of alternative fuels. It ran a trial at its Alicante cement plant in Spain using hydrogen in 2019 and says it rolled the process out to all of its European cement plants in 2021. Other hydrogen-based projects the cement producer is working on include a partnership with Hiiroc, a gas-to-hydrogen plant producer, and the creation of a renewable hydrogen industrial plant in Spain in collaboration with Acciona and Enagas.

Halla Cement awards upgrade project to KHD

30 August 2022

South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.

This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.

The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NOx emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.

Fletcher Building Materials increases sales and earnings in 2022 financial year

17 August 2022

New Zealand: Fletcher Building Materials recorded consolidated sales of US$5.37bn during its 2022 financial year, up by 4.7% year-on-year from US$5.13bn in the previous year. Its net earnings also rose by 42%, to US$273m from US$193m.

The group's concrete division, which includes Golden Bay Cement, contributed US$556m-worth (9%) of group sales. The figure represents an 8% increase from 2021 financial year levels. The business recorded 'strong performances' across all key product segments, underpinned by 'robust' demand and pricing. It made capital expenditure investments of US$51.1m, including in a waste tyre recycling system upgrade at the Golden Bay cement plant. The latter increased the plant's alternative fuel (AF) substitution to 50% from 35%. The company also continued to focus on developing low-CO2 concrete binders.

Fletcher Building Materials chief executive officer Ross Taylor said "The 2022 financial year has not been without its challenges. Global and national supply chain disruptions have continued into the third year of the Covid-19 pandemic." He added "The New Zealand Commerce Commission recently published its interim market study report into residential building supplies. The final report and recommendations will be published in December 2022 and in the meantime we will continue to work collaboratively with both the commission and the government."

KÇS Kipaş Çimento orders Pyrorotor from KHD Humboldt Wedag

17 August 2022

Turkey: KÇS Kipaş Çimento has placed an order with KHD Humboldt Wedag for a Pyrorotor for its Kahramanmaraş cement plant. The supplier says that the equipment will enable the plant's calciner to achieve an alternative fuel (AF) substitution rate of 90%. It will additionally restrict NOx emissions to 800mg/Nm3. After a short shutdown for assemblage of gas duct connections, KHD expects to commission the upgraded system in mid-to-late 2023.

The company says that the KÇS Kipaş Çimento contract represents its 11th Pyrorotor order globally and the first in Turkey.

Lafarge Cement ends Čížkovice cement plant's natural gas reliance through alternative fuels use

17 August 2022

Czech Republic: Lafarge Cement says that it has achieved an alternative fuel (AF) thermal substitution rate of 95% at its Čížkovice cement plant. The plant's fuel mix includes contaminant fractions from local plastic recycling. As a result of the move, the plant no longer uses any natural gas in its cement production.

In 2022 as a whole, the producer plans to increase its share of reduced-CO2 cement sales, increase construction waste recycling in its products and reduce its cement's water consumption.
