Calcium Oxide
Calcium oxide is highly hygroscopic exothermically. Air leaks in the containers and plastic bags which can permeate air must be avoided. The simplest solution is to pack in used but good MS drums, evacuating with a hand air pump and sealing the lid.

Transporting Calcium Oxide
Have you considered using 1 or 2 tonne bags for packing and transportation. The bags could be loaded instandard containers or moved to port in lorries.

Transporting via Drums or Bulk bags is not a cost effective way of transporting large volumes of CaO. I realise that CaO has a high affinity with moisture and is exothermic.
What I am looking for is new technology in bulk transport. It doesnt necessarily have to be via shipping containers, we are willing to look at alternative presurrised container vessels, and if any engineer out there believes that he has designed a new revolutionary presurrised vessel, then we would be willing to talk with that person. ■
Re: Transporting Calcium Oxide
There are (or certainly were) certainly options out there for pressurised and non-pressurised ISO container sized vessels for transport. Metalair (UK) made both horizontal and vertical types, Zeppelin (Germany) had their Bulktainer and Silotainer and I think Clyde (UK) did something on similar lines as well.
What they not un-naturally had in common though is that they are more expensive than a standard ISO container. The reason that there are so many ISO containers around the world are that they are a very cost effective way of transporting products.
It sounds as if you have tried the custom bulk material ISO container and a standard unit with liner. One is too expensive and the other not techncially accpetable. I know of nothing that is cheaper. We use hundreds of ISO's and haven't found anything cheaper for 20 to 30 te loads over longer distances.
As a rule of thumb, if it is a short distance (2 to 3 hours drive) a tanker is best, for longer distances (say 12 to 24 hours) a special dedicated bulk container is best and for deep sea transport go for a standard container with liner and bulkhead.
By the way, most people don't buy their own ISO containers, they hire them as an when required from the shipping lines. ■
Silotainer For Calciumoxide
Hello,
did you find a solution for transporting Calciumoxide by sea? ■
Transporting Calcium Oxide
Does anyone have any idea's of how to effectively transport Calcium Oxide via either shipping containers or alternative.
Currently we use ISO containers, however due to the cost purchasing new ISO containers, and the constant demand to keep them in circulation, we are unable to cost effectively transport our product over longer distances, prefferably by sea.
We have trialed pumping our product into shipping containers, with specially designed plastic liners, however we found that due to the density of our product 1,200 (kg/m3), the product compacted down after travelling for 2 weeks in the shipping container, and was unable to be pumped out of the container. We are seeking a solution, to either overcome the compaction of our product, or an alternative means of transporting our product via shipping.
Any suggestions would be appreciated. ■
