How to Monitor H2S in LACT Units March 27, 2020 Midstream companies have a need to monitor the H2S concentration at LACT Units (Leased Automated Custody Transfer Units). When the crude oil is transferred from the leased location into a pipeline, the midstream company buying the crude has the necessity to get accurate readings of the concentration of H2S in the crude before they take ownership. Controlling H2S is critical to ensure the quality of the crude and to avoid scavenging costs caused by cross-contamination. Furthermore, it protects personnel from toxic and harmf...

Not All Oil in Water Monitors Are Created Equal March 21, 2018 Many widely used oil in water monitors in service today only detect a fraction of hazardous hydrocarbons in water samples, leaving many hydrocarbons un-monitored and contributing to pollution issues around the world. Other oil in water monitors offer a total hydrocarbon measurement including aromatic and aliphatic hydrocarbons and results in more accurate readings. It is important to understand the fundaments differences between the oil in water monitors available before choosing to purchase a monitor. Unfortunately, the widely used o...

Choosing the Right H2S Analyzer for Your Specific Application January 19, 2016 Not all H2S analyzers are created equal, and certain H2S analyzers work better on different applications than they do others. Significant amounts of time, money and headaches can be saved by learning about the different H2S analyzer principles of operation and choosing the correct analyzer for your given application. Measurement of H2S (hydrogen sulfide) is a critical task for product quality control and personnel safety applications. Higher H2S levels results in a less valuable product.

How to Reliably Measure Hydrogen Sulfide in Crude Oil December 10, 2015 The measurement of hydrogen sulfide (H2S) in crude oil is a critical practice for quality control and safety purposes. Without precise quantification of H2S in a process, efficient processing of crude oil is not possible. To maintain safety when transporting crude oil and condensate, measurement of the H2S content is vitally important. Measurement of hydrogen sulfide (H2S) is a beneficial practice for product quality control purposes and for personnel safety of those who may come in contact with sometimes fatal sour gas. Crude oil wit...

Why Lead-Acetate Tape Analyzers Remain the Most Reliable for H2S Analysis November 12, 2015 Over the years new process analyzers have been developed to measure hydrogen sulfide. These include TDL (laser) and UV absorption spectroscopy and electrochemical cells. However, in many applications these analytical methods are not meeting the user expectations and are now being replaced with tape method analyzers. So why, after several decades, are tape method analyzers still dominating the market for H2S analysis? Four (4) Primary Reasons Why Tape Method Analyzers Dominate the Market for Analyzing Hydrogen Sulfide 1.) The tape me...

How to Prevent Process Analyzer Downtime in Wet Weather October 18, 2015 Wet weather can wreak havoc on process analyzers installed outdoors. If it’s your responsibility to ensure process analyzers are running smoothly, there are easy steps you can take to prevent analyzer downtime in wet, rainy weather. This H2S analyzer is properly prepared for wet weather. It is installed in a 3-sides shelter with a roof and has desiccant bags placed inside the analyzer’s cabinet. Not all process analyzers installed outdoors in the field are protected from the elements. Many analyzers have no analyzer shelt...

4 Critical Things You Need to Know When Using Online H2S Analyzers October 7, 2015 If you operate an H2S analyzer, there are 4 things you must know for successful measurements. If you haven’t considered the 4 steps listed below, it’s likely your gas H2S analyzer is not operating as accurately or as reliable as it could. 1.) Check the Material of the Wetted Parts It’s far too often manufactures of H2S analyzers use wetted parts in their analyzers that readily absorb H2S. When H2S is absorbed into parts materials, a phenomenon called “in-gassing” will occur. In-gassing results wh...
