Application: Stabilizers at Oil Refinery

Product : H2S in Crude Analyzer Model 205

Goal: The refinery needs to measure H2S in crude oil for product quality purposes.

Results: After installing the analyzer, the client was able to monitor the H2S levels in the oil continuously online, leading to greater efficiency. This led to great cost savings as well as less time by eliminating the need to grab samples to be carried to the lab for measurement.

Feedback: Lead Process Engineer pleased at the accuracy of the 205 H2S Continuous Analyzer for crude oil when compared to the laboratory. Online automated analysis is great for reducing costs and obtaining a greater efficiency.

Be Alerted of Hydrocarbon Leaks in Cooling Tower Water

oilinwatermonitor — Tue, 03 Aug 2010 21:25:18 +0000

Leaks of hydrocarbons from heat exchangers can emit large quantities of hydrocarbons and Volatile Organic Carbons (VOCs). This can be a hazard from a flammability standpoint as well as cause emissions into the atmosphere. 99.9 to 100% of VOCs are stripped to the atmosphere in cooling towers and have been found to be 12,576 pounds per day from a single exchanger. On-line continuous monitoring can pay for an analyzer in a short time by warning of corrosion leaks. Savings in lost product and laboratory time can be substantial.

Unfortunately, airflow through a cooling tower dilutes the hydrocarbon, allowing higher concentrations than shown on the right column before the cooling tower catches fire.

Hydrocarbons in Cooling Water

Chemical	Saturation in Water PPMw	Headspace Concen. %	Lower Explosive Limit in %	PPMw in Water for Lower Explosion Limit
Benzene	700	11.1	1.35	85
Propylene	762	100	2.00	15
Hexane	140	19.7	1.25	9
Propane	120	100	2.2	2.6

A typical cooling tower with 10 PPM by weight hydrocarbon content will emit 15,000 lbs./day lost product.

The Model 204-V Hydrocarbon VOC in Water Monitor will catch leaks quickly, allowing repairs to be made before major issues arise. The ability to analytically quantify oil in water is greatly enhanced with the Sample Transfer Stripper (Patented Membrane Technology) and the solid state sensor offered by Analytical Systems International (ASI). The analyzer system utilizes many patented and exclusive features only available from ASI.
