Emerson Automation Solutions has designed a new ultra-tight thief hatch to reduce storage tank emissions and help conserve tank contents.
Its new EnardoTM ES-665 spring-loaded device has been created for use on low-pressure storage tanks in response to tighter regulations and the need for improved emissions control from storage tank instruments.
It features increased sealing forces and an “industry-leading” 0.1 standard cubic feet per hour at 90% of setpoint, based on testing at ambient conditions.
The ES-665 (left) provides tank access as well as pressure and vacuum relief to accommodate tank pressure changes that occur under normal conditions. It also limits hatch emissions when pressure or vacuum relief is not required.
In addition to its ultra-tight emissions performance, the device includes an available centre for improved performance of previously installed models, multiple relief settings and material options for application flexibility, and a latching and lockable lid for added security and safety.
Emerson, headquartered in Missouri, US, is a global technology and engineering company for several industrial sectors.
