Clariant, Siemens Team Up
Technology to decrease total capital cost; optimize, simplify plant concepts
Siemens Energy and Clariant, a leader in specialty chemicals, have signed an agreement to cooperate in the commercialization of a jointly developed sour gas shift (SGS) technology for coal gasification.
The agreement appoints Clariant as the exclusive catalyst supplier for all projects where Siemens offers SGS systems. While the collaboration covers all global projects, commercialization will focus on China, which has the highest growth rate of coal-to-chemical projects.
Clariant and Siemens said the SGS technology significantly decreases total capital cost for coal-to-chemical and IGCC applications through optimization and simplification of total plant concepts. The entrained-flow Siemens Fuel Gasifier (SFG) is able to produce syngas from a wide range of fuels – even for low ranks of coal; Clariant's ShiftMax 821 catalyst enables a simple, once-through process without further adjustment of the exit gas from the gasifier, the companies said.
The simplified layout uses smaller and fewer reactors, and requires no steam adjustment for temperature control. Siemens said the technique can handle different steam-to-gas ratios and high carbon monoxide (CO) content in the gas, resulting in improved availability and reliability of the whole process.
