The Intricacy of Proper Instrumentation in Cleaning Produced Water

The cleaning of produced water during oil and gas production and exploration is a crucial, although costly endeavor. In the process of bringing oil and gas up to the surface from a well, several byproducts are also produced. Water is the largest of these byproducts by volume, with 882 billion gallons produced per day. This produced water contains a variety of other compounds and substances, including organic and inorganic compounds, grease, bacteria, and dissolved solids such as iron.

Flow Technologies: Out With the Old, In With the New

As technology advances and new ways to solve old problems are discovered, consumers are left to decide whether existing technology suffices for their specific needs or if they need to pursue new, higher cost technology alternatives. This is very much the case when considering flow instrumentation where moving parts, such as turbines and paddles, are being replaced with non-moving part technologies, such as: ultrasonic, thermal, or electromagnetic sensors. But how do you decide which of these products to select for your flow application? Below is a list of items to take into consideration when deciding between mechanical or non-mechanical technology flowmeters. Continue reading “Flow Technologies: Out With the Old, In With the New”

Control Valve Trim Styles and Flow Characteristics

Hi-Flow™ Valve Cutaway

Hi-Flow™ Control Valves vary the flow in a system by throttling the valve plug in and out of the valve seat. The corresponding flow rate through the valve is based on the valve plug and seat type, which is part of the valve trim. Dwyer Instruments, Inc. offers several flow characteristics, needle plugs, and restricted trim options for the Hi-Flow™ Control Valve series.

There are two types of inherent flow characteristic trim styles available in the Hi-Flow™ product line: Linear and Equal percentage. Continue reading “Control Valve Trim Styles and Flow Characteristics”
