HZI's fabric filter is a product developed by Zosen Inova to remove solids (dust) from the flue gas. It is a physical separation process where the solids are filtered out at the surface of a gas-permeable fabric. If the fabric filter is used in a dry sorption (the XeroSorp process) or semi-dry sorption (HZI SemiDry) process, a filter ...
Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.
