Sample receivers and accessories

The PR-23 and PR-53 are 9-L [2.5-galUS] and 18-L [5-galUS] portable sample receivers designed for the collection of crude oil and refined product batch samples. They have no dead volume and include a pressure gauge, relief valve, and a facility for a customs seal. They have integral mixing pipework and keyed connectors for use with the Jiskoot MS53 laboratory mixer to ensure the homogeneity of samples analyzed.

These compact, portable, constant pressure sample receivers are used for the receipt, storage, and transportation of liquid and gaseous hydrocarbon samples. They are designed to be precharged with inert gas to maintain the sample at process pressure for analysis. The receiver can be supplied with external volume indicators, magnetic sensors, and internal mixing balls.

This intrinsically safe electronic weighing system can measure the mass of samples collected in up to two sample receivers. The control system compares the measured and expected mass of the sample, and the difference is used to provide the performance factor measurements required by sampling standards.

In a sample receiver, heavier components—such as water—separate. Consequently, the contents must be thoroughly mixed to ensure that the sample withdrawn for analysis is representative. The MS53 mixer is connected to a sample receiver, and samples may be drawn from a takeoff valve or through an optional septum. The mixer can also be supplied in a heated enclosure for temperature-critical oils.

These noninvasive sensors allow a sampler controller, such as a Jiskoot InSpec™ sampler controller, to continuously monitor the filling of a constant pressure sample receiver. This fulfils the requirements of the sampling standards ISO 3171, ASTM D4177, API MPMS Chapter 8.2, and IP 6.2.
