The cap has a (1) first, open position in which at least one body opening and at least one shutter opening are not aligned and the cap is configured so that fluid cannot readily pass therethrough, (2) second, open position in which the at least one body opening and the at least one shutter opening are aligned and the cap is configured so that fluid can pass therethrough, and (3) third, closed and locked position, in which the at least one shutter opening and the at least one body opening are not aligned and fluid cannot readily pass through the cap, and the cap is configured to not be moved to an open position.

The present invention relates to a method and system for measuring total chloride content in a process product stream. In particular, the present invention relates to a method of measuring hydrogen chloride and organochloride content, in situ, for a gaseous refinery process product stream. This method allows for measurement of hydrogen chloride and organochloride content in a single test method, which allows for optimised performance and maintenance schedules for chloride guard beds used within the refinery process.

A relief valve in a hydrocarbon site is shown. The relief valve is disposed within a housing. The housing includes a first engagement component coupled with a valve spring and a second engagement component axially aligned with the first engagement component. The second engagement component is configured to engage with the first engagement component during an operation cycle to translate the stem along the axis in response to the pressure within the relief valve being above the predetermined threshold. In some embodiments, the second engagement component is formed at least in part of a carbide substrate.
