System and method for syngas clean-up

摘要

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

1. A method of processing unconditioned syngas, comprising:
(a) removing solids and semi-volatile organic compounds (SVOC) from the unconditioned syngas to form a first depleted syngas stream which has a reduced amount of solids and SVOC relative to the unconditioned syngas; (b) after step (a), removing volatile organic compounds (VOC) from the first depleted syngas stream to form a second depleted syngas stream which has a reduced amount of VOC relative to the first depleted syngas stream; (c) after step (b), removing at least one sulfur containing compound from the second depleted syngas stream to produce a sulfur-depleted syngas stream which has a reduced sulfur amount of sulfur relative to the second depleted syngas stream.
