A solid carbonaceous product from the Coal Tar Filtration plant is fed into a coker unit at high temperature and pressure. The light products produced in the cracking process in the coker drums are routed back to our refining units. A solid black substance form in the coker drums. The solid black substance (also known as green coke or raw coke) consist of around 90% fixed carbon. This is also known as SASGREEN material. The SASGREEN material is then fed into a kiln (calciner) with the operating conditions closely controlled within specific parameters depending on final application. During the calcination process the structure and physical properties of the material change while most of the moisture and volatile matter are removed. The result of this process is a calcined pitch coke used for the production of SASCARB, SACOKE and CORRCARB material. SASCOKE of different grades are shipped internationally in bulk depending on customer requirements and final application. The SASCARB material is packed into different bag sizes from 8kg to 1ton bulk bags and different particle size distributions (PSD) depending on customer requirements. The SASCARB material is containerised and distributed Worldwide. One of the highly specialised materials produced in our process is known as CORRCARB which is used in the corrosion protection industry for the protection of pipelines and vessels against the destructive force of oxidation of the construction metal.
