In this gas station, the water bath heater is located to heat up a maximum of 1000 m 3 /hr natural gas at nominal load. The inlet pressure in normal condition is 50 bar (5000 kPa) and the outlet pressure should be 16 bar (1600 kPa) [20] .
Indirect fired heaters Gas Smart Metering
Gas heaters are fired with natural gas which will be supplied to the burner at a specific pressure thanks to a dedicated fuel gas pressure regulators complete of all the required safety devices and electrical heating on a dedicated line. Used in order to reduce the viscosity to ease the oil stream transportation.
Study of preheating natural gas in gas pressure reduction
The natural gas first passes through a heater for preheating before it enters the regulators. Because the CGS heaters consume large amounts of gas, any decrease in gas consumption provides
Self Heating Pressure Reducer Gas Decompression CNG
VPRS Vortex Pressure Reduction Stations for Pipeline Natural Gas and CNG. A proprietary CNG decompression process (Vortex PRS_CNG) allows for complete elimination of high pressure gas preheat and raises the pressure regulated gas temperature also without applying any external man made energy.

US6155051A Method of heating natural gas in a city gate
Natural gas from a main supply line 4 enters the City Gate station. The temperature of the gas in the main supply line 4 will vary depending upon the particular climate, but may be as low as approximately 35 degrees Fahrenheit. The natural gas from the main supply line 4 is directed into a heat exchanger 6.
Natural gas reducing and metering stations Gas
Natural gas reducing and metering stations The aim of a pressure reducing skid is to regulate the NG outlet pressure to a setting value. One typical solution consists mainly of two reducing streams (2x100% capacity) with two regulators each: one is the main regulator and the other is
GAS SUPPLY DESIGN GUIDE Home AERCO
AERCO Innovation and Reconseries heater s require a stable natural gas (all units) and propane (Innovation only) input pressure. The nominal inlet supply pressure to the heater is 7.0” W.C. The allowable natural gas inlet pressure range is 4.0” W.C. (min.) to 14.0” W.C. (max.) when firing at maximum input. For
Efficiency and heat losses of indirect water bath heater
At present, water bath heater is widespread used for gas industry to heat the natural gas. Its large size, the need for water reposition, its low thermal efficiency and large
Journal of Natural Gas Science and Engineering
Heater gas consumption Natural gas Temperature controller abstract Some stations in the gas transportation system experience a decrease in natural gas (NG) pressure. The drop in pressure occurs in the regulators and causes the temperature to drop so that the gas must be preheated to prevent it
Feasibility of employing solar energy in natural gas

Method of natural gas pressure reduction on the city gate
A method of natural gas pressure reduction at a City Gate station providing an elimination of the station's energy consumption for gas flow heating together with the creation of a cooling duty for further utilization which comprises connecting a vortex tube inlet with a gas flow line for applying the whole gas flow entering the City Gate, connecting a cold fraction gas flow outlet from the
Study of Preheating Natural Gas in Gas Pressure Reduction
Gas pressure reduction station has built to reduce gas pressure. Process of passing through regulator lead to forming hydrated and pipe obstruction. Indirect water bath heater is a common device to heat natural gas before regulation. Most of thermal energy generated in burner of these heaters wasted by flue gas
Vortex Pilot Gas Heater Universal Vortex Inc
Results: After installing a Dual Path Vortex Pilot Gas Heater at both Stations, UVI's client was able to shut down its line heaters during the summer months and reduce the gas discharge temperature to 0ºC (32ºF) in the winter time. The estimated savings for the client in fuel gas is $150,000/year.
Natural Gas Preheaters Wattco
The natural gas preheaters are generally designed to prevent the Joule Thompson effect using Electrical Block Type Process Heaters. It is an indirect heater with aluminum encased block protected by stainless steel or carbon shell. It is called heat exchangers and is one of the best methods to heat up the natural gas before transmission.
Natural Gas EXHEAT
Natural Gas. Usually, a pressure reduction valve (PRV), ie a throttle valve (also known as Joule Thomson valve) is used at Pressure Reduction Stations (PRS) to reduce natural gas pressure before supply to a local gas distribution network. This pressure reduction in a PRS by a throttle valve results in reduction of both pressure and temperature of natural gas.
Reducing energy consumption in Natural Gas Pressure Drop
liquid or solid phase condenses at the station exit. Indirect Water Bath Gas Heaters (known as line heater) are employed in the CGS to preheat the natural gas. The heaters are consuming a considerable amount of natural gas flowing though the CGS as fuel to provide the required heat for preheating the natural gas stream.
