For calcined petroleum coke our company produces, the kilns we adopt are downstream pot calciners with eight-layer fire tunnels. Kilns of Phase 1 uses general types of silicon bricks as pot wall bricks, and consists of 10 kilns with 32 pots each and calcination temperature of 1250℃～1350℃ with capacity of 280kt/a; Kilns of Phase 2 uses patented product developed independently by our company as pot wall bricks, and consists of 8 kilns with 48 pots each and calcination temperature of 1350℃～1450℃ with capacity of 350kt/a.

Our Company
Sinoway Carbon Co.,Ltd.(SINOWAY), set up in 2011, jointly invested by Sinoway Carbon Energy Holdings Ltd.(Shenzhen) and Dubai Aluminium (UAE), is mainly engaged in production and sales of calcined petroleum coke (CPC) and steam with registered capital of USD 15,500,000 and total investment of RMB690 million. SINOWAY’s CPC products are mostly exported to Middle East, USA, Australia, Russia, India, etc.
SINOWAY has planned capacity of 640,000 tonnes of CPC per year to be built in two phases, of which first phase was smoothly put into operation in Jun., 2013 and second phase will go into operation by end of 2015. SINOWAY has a high efficient system of waste heat recycling, which can supply around 700,000 tonnes of clean energy per year to chemical plants nearby.
