Proven Results

Equistar Chemicals

Application: Heat Exchanger and Cooling Towers

Product Type: Model 204 – Hydrocarbon (VOC) in Water Analyzer


This ethylene plant had two goals: to prevent the loss of their product; and to save hundreds of thousands of dollars by early detection of hydrocarbon leaks in the water of heat exchanger / cooling towers.


1) Saved the client hundreds of thousands of dollars of lost product by early leak detection in heat exchangers.

2) At a level of 2 PPB, the client was able to take corrective action and benzene concentration began to decrease.

3) A typical cooling tower with 10 PPM by weight hydrocarbon content will emit 15,000 lbs/day lost product at 1,500 million lbs/day flow rate.

Enterprise Products

Application: Measure Sulfur to Protect Catalytic Beds

Product Type: Series 1700 – Total Sulfur Analyzer


This chemical plant was required to measure their total sulfur in order to prevent costly damage to the system by warning of total sulfur concentrations.


1) The client was able to measure total sulfur with the series 1700 total sulfur analyzer in the catalytic bed to prevent poisoning.

2) This saved the client millions in damages to the catalytic beds.

Customer Feedback:

“Initially, measurement of the output to the catalyst was purchased but after reliable operation and costs savings were verified, analyzers were installed in the plant inlet in the middle of the process and outlet to optimize plant performance and reduce costs associated with catalyst replacement. These analyzers are extremely cost effective.”

Royal Dutch Shell

Application: Government Compliance Mandate for Hydrocarbons in Cooling

Product Type: Model 204 – VOC in Water Analyzer


California’s environmental regulations required this client to use a precise and reliable method to monitor VOC’s in the cooling towers for environmental protection.


1) ASI KECO provided an analyzer to the client enabling them to comply with California’s strict environmental mandate.

2) Enhanced plant safety.

3) Hundreds of thousands of dollars in cost savings and environmental protection.


Application: Measure H2S Content in Waste Water

Product Type: Model 205 – H2S in Water Analyzer


This wastewater treatment company needed to prevent odor and costly corrosion repairs to equipment.


1) Analytical Systems saved the client tens of thousands of dollars in costly repairs by preventing inefficient product loading into the wastewater for treatment.

2) Provided an accurate and reliable continuous analyzer to monitor the specific concentration of H2S in the water.

Hanla IMS

Application: Monitor Oil in Water for Vessel Bilge Water and Produced Water

Product Type: Model 204 – Oil in Water Monitor


This client produces water FPSO sea vessels. They needed a highly customizable oil in water monitor to operate in extreme conditions with caustic sea water service. The product needed to be rugged, and able to withstand the tropical environment and corrosive components in the sample water.


1) Analytical Systems Int’l. provided a highly efficient and accurate Oil in Water monitor customized for the client’s exact application needs.

2) Provided an ideal analyzer capable of handling toxic components and withstand the extreme operation environment.

Saudi Aramco

Application: Crude Oil Stabilizers

Product Type: Model 205 – H2S Content in Crude Oil Analyzer


This oil refinery must meet sales permit specifications of their crude oil. The client also needed a continuous, reliable and accurate measurement of the H2S content in crude oil.


1) The client was able to reliably, accurately and continuously measure H2S content level directly in the crude to meet stringent permit specifications for sales purposes using the Model 205, H2S in crude analyzer.

2) This greatly reduced client costs by eliminating the need for costly, laborious and inaccurate lab analysis which was required multiple times per day.

3) Outdated laboratory methods require grab samples which deteriorate with time and H2S escapes during sampling.
