C-Capture's solvent-based carbon capture system wins IChemE Global Awards Energy award

25 November 2022

UK: C-Capture won an IChemE Global Award in the Energy category for its solvent-based carbon capture system. C-Capture's model differs fundamentally from currently commercially available systems, offering a lower energy penalty than technologies including amine-based capture. It is robust in handling impurities in flue gases, including O2, SOx and NOx, while offering competitive cost and safety performance.

CEO Tom White said “Being shortlisted was honour enough, but to win the global Energy award is fantastic recognition for the C-Capture team and our unique carbon capture technology. The IChemE Global Awards represent the pinnacle of excellence in chemical process engineering. This achievement is testament to our exceptional team and their commitment to accelerating the global adoption of carbon capture and storage to achieve net zero by preventing greenhouse gases from entering the atmosphere.”

Fives to supply Pillard NOVAFLAM burner to cement plant in France

30 September 2022

France: Fives has secured a contract to supply a 65MW Pillard NOVAFLAM Evolution burner to a cement producer. The customer’s aims are to continue to maximise alternative fuel (AF) use, to improve clinker quality and to reduce NOx emissions at its cement plant. The order also includes precalciner burners and a natural gas-powered 35MW Pillard hot gas generator, as well as valve trains and pumping systems.

Cemex UK purchases 10 reduced-CO2 tipper trucks

01 September 2022

UK: Cemex has bought 10 Volvo 460 8x4 tipper trucks for use at its Angerstein Wharf aggregates depot in Greenwich. From there, the trucks will deliver sand and aggregates all around London. The trucks’ bodies are made of lightweight aluminium, and they conform to Euro 6 emissions standards. This corresponds to 80% NOx emissions reduction and 50% particulate emissions reduction compared to Euro 5 standards.

Cemex UK fleet engineering manager Nigel Ponton said “The addition of these new trucks to our fleet will enable us to better meet customer demand, safely and efficiently. Safety is the number one focus whenever we add new trucks to our operation and these Volvos tick every box in that respect.” Ponton continued “These trucks will all be working in busy streets across London so it’s imperative we provide our drivers with the best tools possible to do the job and help protect any vulnerable road users. Moreover, thanks to the improved fuel efficiencies and enhanced payload these new Volvos are the most sustainable vehicles we’ve ever had and will help decarbonise our delivery footprint.”

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.

Cementos Molins targets 20% CO2 emissions reduction by 2030

16 February 2022

Spain: Cementos Molins has committed to a 20% reduction in its CO2 emissions between 2020 and 2030. The company has set out its strategy in its 2030 Sustainability Roadmap. The roadmap covers five areas: health and safety, energy and climate change, the circular economy, nature and the environment, and corporate social responsibility. Thus, Cementos Molins aims to achieve an accident-free workplace, to source 55% of its electricity consumption renewably, to increase its alternative fuel (AF) substitution rate to 40% and reduce its cement’s clinker factor to 68%, to halve particulate matter emissions and cut nitrous oxides (NOx) and sulphur oxides (SOx) emissions by 40% and 10% respectively and to have signed official agreements with all host communities and employ women in over 23% of management positions.

Chief executive officer Julio Rodríguez said “Sustainability is the cornerstone of our strategy here at Cementos Molins, and today we are delighted to announce the specific targets that we have set out in our 2030 Sustainability Roadmap. The targets and their corresponding action plans - the result of the hard work and dedication of the Cementos Molins team, together with our stakeholders – will help drive our company forward in actively tackling climate change.” He added “We are deeply committed to achieving zero emissions and building a better world for everyone.”

FLSmidth to supply 11,500t/day kiln line for Shree Cement’s upcoming Nawalgarh cement plant

12 October 2021

India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

Henan Province to raise utility costs for polluting cement producers

09 July 2020

China: Henan Province has announced a planned rise in water and energy tariffs for cement producers that fail to meet current emissions standards and clean transportation requirements. Reuters News has reported that companies subject to the measures will pay US$0.07 – US$0.14/m3 more for water and up to US$0.01/kWh more for electricity. Henan enacted ‘ultra-low’ emissions limits of 10Mg/Nm3 of dust, 50Mg/Nm3 of NOx and 100Mg/Nm3 of SO2 in 2018. Cement plants in the province produce 105Mt/yr of cement.

Cement producers agree on NOx emissions reduction in South Korea

11 June 2020

South Korea: All nine domestic cement producers and the Ministry of Environment have agreed on measures to reduce NOx emissions. Asia Cement, Halla Cement, Hanil Cement Manufacturing, Hyundai Cement, Korea Cement, Sampyo Cement, Ssangyong Cement Industrial, SungShin Cement and Union Corporation have agreed to invest in upgrades to filters or new high-efficiency filters and process improvements, according to the Korea Times newspaper. There was also an agreement to set NOx emissions reduction targets for the allocation of funding. The Korea Environmental Industry Technology Institute is investing US$2.93m in research towards developing methods of selective catalytic NOx emissions reduction and selective non-catalytic NOx emissions reduction.

The government aims to reduce national NOx emissions by 20% to 155,000t/yr from 195,000t/yr through subsidies to emissions reduction technologies development and uptake. The cement sector presently emits 62,500t, 32% of the domestic total.
