| JFE Chemical has developed the effective agents for intensive desulfurization in the gas purification under dry condition. We supply three types of desulfurizing agent to remove organic sulfur compounds such as H2S, CS2 or COS in response to the wide variety of customer needs. Remarkably, our products can show the desulfurization performance at comparatively low temperature, which can realize smaller facilities and lower cost. |
