Technical requirements for equipment with high sulfur content
Thread Content
One separator, one desulfurization tower; the medium is coalbed methane. The operating pressure is 0.7 MPa, with a required design pressure of 1.6 MPa. The operating temperature ranges from -15 to 40°C, while the ambient temperature ranges from -25 to 50°C. The hydrogen sulfide content is 1267 ppm, and the total sulfur content is 1953 mg/m3. Is it necessary to conduct a sulfur resistance assessment for this equipment? Is ultrasonic testing required for steel plates? Thank you!
Since there is H2S, stress corrosion should be taken into consideration. For plate thicknesses greater than 12, ultrasonic testing is required; HG20581 7.8.2 contains regulations regarding this
GB150 standards require ultrasonic testing for steel plates
