The present disclosure relates to sampling devices for sampling solutions, such as high temperature chemical solutions, in certain industrial processes. The sampling device is integrated with a recirculation line from which a sample is drawn thereby reducing or preventing clogging of processes components resulting from precipitation of the solution.

A ballast water monitoring device and a method for detecting live phytoplankton are disclosed. The device comprises a chamber for receiving a sample, at least one light source to emit light towards the sample, a light detector to receive light from the sample and generate a light signal, and a controller. The controller is configured to control the at least one light source to emit a single pulse of light, calculate the variable fluorescence [Fv] of the sample in response to the pulse of light, at time intervals less than the duration of the pulse of light, compare the calculated variable fluorescence to a predetermined reference limit, and perform an action if the calculated variable fluorescence is greater than the predetermined reference limit.

A process for analyzing a hydrocarbon stream comprises: withdrawing a hydrocarbon sample from a hydrocarbon stream; passing the hydrocarbon sample to an analysis device at a target temperature of greater than 120 C. and a target flow rate of greater than 20 liters per minute; and returning the hydrocarbon sample to the hydrocarbon stream. The process may be used for the on-line analysis of crude oil, in order to optimize a refinery operation.
