Patented technology with free choice of the export steam’s pressure (typically in the range 10÷70 bar g).
Casale has put in place a program of services to assess the performances from the entire plant down to the single critical items as well as for auditing the plant operations, with the purpose to improve the production efficiency and/or reduce the environmental footprint and/or identify specific bottlenecks.
The operating conditions for a pure oxygen burner for partial oxidation (POX) are extreme due to the extremely high temperature needed to achieve a high conversion of natural gas to CO and H2: the reformed gas temperature at the reactor outlet is maintained in the range of 1,200-1,400°C, with the maximum flame temperature around 2,800-2,900°C.
The pre-reformer is an adiabatic catalytic reactor placed upstream the reformer in which the higher hydrocarbons contained in the natural gas feed are converted into methane thus preventing the formation of coke in the primary reformer feed preheat coil and at the catalyst tube inlet.
Casale's sour CO-shift converter features our well-proven, reliable axial-radial flow internals. With this kind of arrangement, most of the gas passes through the catalyst bed in the radial direction, resulting in very low pressure drop. The balance passes down through a top layer of catalyst in an axial direction, thus eliminating the need for a complicated, gas sealed top cover on the catalyst basket.
