a Comparison between Screw Compressor and Other Machines

What are Screw Compressor? Screw compressors have been used on air and various refrigeration and process applications for a great number of years. In recent years the machines have become very popular in the natural gas industry in booster and gas gathering applications. Declining field pressures in the USA and Canada are forcing the industry to look at […]

Smart Instruments and Systems

Smart Instruments and Systems By Akram S. Alkhuzaie Introduction: Smart Transmitters are advancement over conventional analog transmitters. They contain microprocessors as an integral unit within the device. These devices have built-in diagnostic ability, greater accuracy (due to digital compensation of sensor nonlinearities), and the ability to communicate digitally with host devices for reporting of various process […]

what are Boiler Types

Industrial ,Commercial and Institutional Boilers Combustion boilers are designed to use the chemical energy in fuel to raise the energy content of water so that it can be used for heating and power applications. Many fossil and non-fossil fuels are fired in boilers, but the most common types of fuel include coal, oil, and natural gas. During […]

what does choke valve mean

Most Common Choke Valves: •Positive: –Fixed orifice. –Disassemble to change bean. •Adjustable: –Provides variable orifice size through external adjustment. A choke is a restriction in a flow line that causes a pressure drop or reduces the rate of flow. It commonly uses a partially blocked orifice or flow path. Variable Chokes – good for bringing […]
