Emergency shut-off valve for crude oil cracking unit
Project: Russian "Ural Chemicals" Factory
Task:
Due to the slow response of the valve when pressure suddenly rises, there is a risk of explosion.
The sealing components corrode due to sulfur compounds (such as H₂S, with a concentration exceeding 5000 ppm).
Solution:
120 Betis™ HTS type pneumatic-hydraulic actuating devices were installed, with a response time of only 0.3 seconds.
The shell and sealing components were made of nickel-based alloy Inconel 625.
Result:
The emission of harmful gases has decreased by 99.7%.
The service life of the valve has been extended to 5 years, compared to the original 6 months.
