MP CLEAN AIR C5323 Reducing SO2 emissions in Borneo
To comply with its SO2 emission licence, Indocement could see no alternative but to import expensive low sulphur coal.
The client worked with Jord to develop a cheaper alternative to the imported coal. The solution was to use locally available raw meal as a reagent to produce synthetic gypsum and reduce SO2 emissions. If it worked, the plant could use less expensive local coal together with the raw meal to keep under the required SO2 limits.
The result has delighted Indocement. The stack emissions are now well below the license limit, lower cost coal can be burnt and the synthetic gypsum has replaced about $US250,000 p.a. worth of imported gypsum. Jord had the pleasure of meeting the environmental, community and economic needs of its client, in a remote and demanding location.

MP CLEAN AIR C7000 Dust scrubbers for Panama copper
Without effective scrubbing, the conveyors in the reclaim tunnel become buried in dust, reducing efficiency and risking the health of those who work in the area. Cobre was required to control the dust concentration to protect its operators, maintain production levels and comply with its operating licence.
For this challenge, Jord chose the Low Energy Venturi Scrubber (LEVS), a robust bag-less scrubber with few moving parts, few instruments and simple controls. It uses relatively little energy, has a small foot-print and requires little maintenance. Characteristics that are ideal for a remote location such as this.
Jord’s design met the brief, efficiently collecting 15 tonnes of dust per day, all but eliminating dust build up in the reclaim tunnel and significantly reducing the ‘housekeeping’ collection of fugitive dust. That in turn improved operational efficiency, maintenance and production throughput.

O&G DC FT&C C4094 and C7323 5,000km up the Amazon River
With the mighty Andes mountain range prohibiting access by road from Lima to site, transporting the equipment safely to site caused heads to scratch.
The optimal route of transporting the 18 air coolers and 9 scrubber vessels was a 5,000 km barge journey to the upper reaches of the Amazon river. Meeting the project schedule was critical, as the river is only navigable for a short duration after the wet season. Any delay would push the plant start up back 12 months.
The air coolers were delivered in modular form, to provide better protection during the long voyage from Jord’s Asian based fabrication centre. Close attention was paid to corrosion protection of the coolers and scrubbers, given the many months of ocean and river travel, between workshop and site.
The high pressure scrubbers vessels used a combination of internals; multi-cyclones for solids removal and vane packs for liquids. Maximum flexibility was incorporated into the designs, to handle 28 operating cases over four phases of the gas plants expected design life.
