Fairport Engineering reports work on filters at Ketton cement plant
15 February 2017UK: Fairport Engineering has reported work on its replacement of two electrostatic (ESP) filters at Hanson’s Ketton cement plant in Rutland. Following discussion in early 2016 Fairport was contracted to replace ESP filters at the plants Mills 9 and 10. Both mills were shut down for planned three-week periods each to remove the old filters and install the new ones. The new system on Mill 9 also required the installation of new screw conveyors, rotary airlocks and the reconfiguration of existing control panels, plus the installation of new 160KW central exhaust fans and associated clean gas ducting. Fairport reports that, to date, the daily averages on both filters are well below the target emission level.
Filter system to be upgraded at Vencemos’ Pertigalete plant
24 January 2017Venezuela: The filter system at the Venezolana de Cementos (Vencemos) plant in Pertigalete is to be upgraded. The plant has reportedly had a capacity utilisation rate of 20% due to its filters, according to the Nueva Prensa newspaper. The state-owned company lacks the funding to import new equipment so the work will be conducted locally with a budget of US$25m. The upgrade is expected to be completed by the end of February 2017.
Following inspections at the plant, managers denied that the plant was operating at 20% of its capacity, despite the comments of workers at the plant. However, they did agree that its was operating below full capacity due to faulty equipment at the Planta I unit. Workers protested in mid-January 2017 over high levels of emissions at the plant
The Pertigalete plant reportedly produced 45% of all cement in the country in 2016 and it has a target of 66% in 2017.
Netzsch Trockenmahltechnik releases details of Smart Removal filter hose changing system
20 September 2016Germany: Netzsch Trockenmahltechnik, the dry products processing arm of Netzsch, has released details about its Smart Removal filter hose changing system, which combines the advantages of top and side removal systems in one product. The new system was developed to enable a filter hose change without tools, which could be carried out easily and rapidly, to cut costs. Additional focus was placed on reducing the residual dust content down to that of a top removal system. The new technology is designed to reduce mounting errors. Netzsch describe the mounting of the Smart Removal as up to 80% faster than previous side removal systems and that its low residual dust content is comparable to that of conventional Top Removal systems. The development was announced at the Powtech exhibition in Nuremberg in April 2016.
Algeria: Cement production has resumed at the Société des Ciments Sour El-Ghozlane plant following maintenance work and an upgrade to add an electrostatic precipitator filter. The 1Mt/yr plant, a subsidiary of Buzzi Unicem, has been shut for nearly two months causing a shortage of cement in the central region of the country. This has led to some construction projects stalling and the cost of cement rising, according to El Watan.
US: Haldor Topsoe, a catalysis producer, and FLSmidth, a supplier of equipment and services to the global cement and minerals industries, have signed a cooperation agreement that marks the beginning of a joined global effort to commercialise a new catalytic filter bag technology.
"Developing this product has been a combination of the very best that Topsoe and FLSmidth have to offer from an R&D perspective," said Bjerne S Clausen, CEO of Haldor Topsoe.
The product has been designed over the last four years and will carry the brand name EnviroTex catalytic filter bags. It is capable of removing dust, volatile organic compounds and nitrogen oxides in one integrated and cost-effective process. The patent-pending catalytic filter bags use three layers of filter fabric. Each layer contains a tailored catalyst optimised for the removal of specific kinds of compounds from the off-gas that passes through it.
As part of the agreement between FLSmidth and Topsoe, the new product will be manufactured at FLSmidth's bag production facilities in Georgia, USA. The filter bags will then be catalysed and assembled at Topsoe's catalyst production site in Houston, Texas. Topsoe's production site will be expanded with a new production line dedicated to the production of EnviroTex catalytic filter bags. The goal is to complete construction of this facility by the end of 2015.
Suez Cement orders bag filter system from Boldrocchi
11 December 2013Egypt: Suez Cement has ordered a bag filter system from Boldrocchi srl for its Helwan Plant. The turnkey contract includes new bag filters, a heat exchanger and fans for the kiln, raw mill and clinker cooler. This will replace the plant's existing baghouse and glaver bed filters.
Previously Italian engineering firm Boldrocchi had signed a contract with the Helwan Plant in 2012 to provide bag filters and fans for the Helwan Plant. Line one was commissioned in November 2013 and Line two is expected to be completed at the end of May 2014.
ENTECCOgroup acquires Turbofilter GmbH
05 December 2013Germany: ENTECCOgroup announced on 2 December 2013 that it has acquired Turbofilter GmbH in order to further strengthen its activities in the steel and flue gas cleaning industry.
Turbofilter GmbH, founded by Fritz von Opel in Essen in 1958, has more than 50 years of experience in offering process-oriented solutions for industrial dust removal and flue and exhaust gas cleaning worldwide. It manufactures standard filters and complicated turnkey plants in the field of environmental technology.
"The union with the ENTECCOgroup and the restructuring of Turbofilter GmbH concerning long-term job and location security, as well as the positioning in the market, are the right steps at the right time. Together with the ENTECCOgroup we will speed up our expansion even faster," said Rainer Bertling and Jürgen Waller, shareholder and manager of Turbofilter GmbH.
ENTECCOgroup has made the environmental technology industry a priority. The industry expanded from US$560m in 2003 to US$744m in 2010 and currently employs more than 3.5 million workers in Europe. These numbers are expected to double by 2020.
Cimentos Mozambique order US$8m filter from American Air Filter
12 September 2013Mozambique: Cimentos Mozambique has signed a contract for the manufacture and installation of a filter to reduce the emissions from its cement plant in the southern city of Matola. The US$8m order has been placed with American Air Filter for installation in 2014.
"Protecting the environment and the health and well-being of the residents of Matola and the surrounding area was one of the first points on the agenda of the new management of the factory. We are convinced that we will be in a much better situation when the new filter is installed next year," said Cimentos Mozambique spokesman Sergio Bandeira.
Cimentos Mozambique is Mozambique's largest cement producer. In late 2012 Brazilan cement producer InterCement took over the company from Cimpor.
Hima to install US$3.2m bag filter upgrade at Kasese by May 2013
06 February 2013Uganda: Hima Cement has decided to spend US$3.2m to upgrade its bag filter technology at its Kasese cement plant in western Uganda. The move follows a history of complaints from local communities over dust emissions. The upgrade will be installed at the factory's old production line, which plans to bring stack emissions in line with global standards. It is expected to be completed by May 2013.
"We are confident that this time round the problem of emissions will become a thing of the past since the same technology was installed at our Bamburi Cement factory in August 2012," said David Njoroge, Hima Cement general manager.
The upgrade is the second attempt that Hima Cement has made at its old line in Kasese. Previously an electrostatic precipitator (ESP) failed due to frequent power cuts. In 2011 Kasese's new production line, which uses bag filter technology, was opened to increase cement production capacity from 300,000t/yr to 850,000t/yr.
