Abstract

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.

First claim

What is claimed is:

1. A process for analysing a hydrocarbon stream, said process comprising:
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; wherein the analysis device is used to measure a chemical property of the hydrocarbon fluid, a physical property of the hydrocarbon fluid, or combinations thereof, and wherein the analysis device measures the chlorine content of the hydrocarbon fluid.

2. A process for analysing a hydrocarbon stream, said process comprising:
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, wherein the hydrocarbon sample is passed through a filter before it is passed to the analysis device.

3. A process for analysing a hydrocarbon stream, said process comprising:
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, wherein the hydrocarbon sample is passed through a filter before it is passed to the analysis device, and wherein the hydrocarbon sample is filtered at the target temperature and the target flow rate.

4. A process for analysing a hydrocarbon stream, said process comprising:
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, wherein the hydrocarbon sample is passed through a filter before it is passed to the analysis device, and wherein the hydrocarbon sample is filtered at the target temperature and the target flow rate, and wherein the filter is backwashed using a backwash medium.

5. A process for analysing a hydrocarbon stream, said process comprising:
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, wherein the hydrocarbon sample is passed through a filter before it is passed to the analysis device, and wherein the hydrocarbon sample is filtered at the target temperature and the target flow rate, and wherein the filter is backwashed using a backwash medium, and wherein the backwash medium is at the target temperature of the hydrocarbon sample.
