EZX-4 deep purification fine desulfurizer is used in large methanol plants or coal to oil plants, which can further remove the sulfur content from the low-temperature methanol wash outlet of<0.1ppm to<20ppb, especially for working conditions where the gas source contains trace amounts of thiols. It achieves the goal of deep purification of hydrogen sulfide, carbonyl sulfide, and thiol in a product, extending the service life of the methanol catalyst to 5-6 years, achieving the replacement of the methanol catalyst only once every two major maintenance cycles, doubling the service life of the Fischer Tropsch synthesis catalyst, and achieving greater economic benefits for the enterprise.
1. Performance Characteristics
1. Good catalytic activity, with export H2S, COS, and thiol content all<7ppb, ensuring total sulfur<20ppb.
2. Use high airspeed, which can be used at airspeed up to<5000h-1.
