Not all Water is Equal
Water plays an integral part in the petroleum refining process. A tremendous amount of water is used in a refinery – from mixing and separating the crude oil, to cooling the distillation tower with cooling water, and finally discharging the treated wastewater to surface water or wells. This is a general overview of the petroleum refining process, highlighting the composition of water at different stages in the refining process. However, this article will specifically discuss the Importance of proper elastomer selection for seals in valves, pumps and gaskets in refinery processing equipment that handles these varying water compositions.

BTG Tail Gas Butterfly Valves
Design and Construction
DeZURIK has specially designed the Tail Gas High Performance Butterfly Valve to meet the rigorous requirements of services where polymerization or solidification of media can prevent valve operation, including tail gas service in refinery sulfur recovery units, polymer processing or adhesive manufacturing. DeZURIK standard High Performance Butterfly
Valves are available with standard steam jackets for less rigorous requirements, but Tail Gas Valves include unique features which keep the valve at process temperature and protect critical bearing and seat areas. In addition to steam jacketing the body, internal steam passage ports are located near the upper and lower body bearings. These features
prevent hydrogen sulfide and other media from solidifying, freezing the bearings, damaging the seat and preventing tight shutoff. NACE trim is standard (NACE MR0175) with 316 stainless steel bearing.
