Abstract

A multi-test assembly for evaluating, detecting and monitoring processes at elevated pressure is described. The Mufti-test assembly has a pressure vessel equipped with trays or plates with a multitude of individual test cells, an optional lid for sealing the cells, and a system for the detection and/or monitoring of the processes in each individual test cell, in situ. Uses of the invention are detection of solid structure formation or phase transformation in, for example, hydrocarbon systems or mixtures of hydrocarbon and water, and also in an automated test which is optimized simultaneously with regard to several test parameters in the testing of inhibitors for gas hydrate formation. The multi-test assembly has built-in systems for pressure and temperature control. The assembly may also be connected to a set-up for the automatic dosing of reagents.
