Indirect water bath heater are sometimes called line heaters. Indirect fired water bath heater /Line Heaters is the process equipment need to prevent hydrates. Hydrates are often formed during depressurization or sudden decrease in pressure. Hydrates are poison which will block and damage downstream equipments , valves and instruments.

Indirect fired heaters /Line heaters heat the gas stream before and / or after the choke so that the gas is maintained above the hydrate temperature. Indirect fired water bath heater / Line Heaters can be used to heat crude oil for treating, heat a hot fluid circulating medium. Most common equipment type used to heat a well stream is the indirect fired water bath heater/Line heater.

Indirect fired water bath heater/Line Heater is used to maintain or increase above 120 deg F, which is well above hydrate formation temperature for LTX.

In fire tube Indirect fired water bath heater/Line heater, the coils are immersed in a bath of water, the water is heater by fire tube that is in the bath below th coils. That is fire tube in indirect fired water bath heater(Line heater) provides heat flux that heats the water bath. Indirect fired water bath heater(Line Heater) exchanges heat by convection and conduction to the process fluid. On other hand, instead of fire tube the electrical immersion heaters are used to heat water bath in indirect fired water bath heater/Line heater. Fire tubes in indirect fired water bath heater (Line heaters) are by far most common source of heat.

Limitation in indirect fired water bath heater /Line heater is bath temperature to 190 deg F to avoid evaporating the water, if higher temperature are needed, glycol can be added to the water in indirect fired water bath heater/Line heater.

Purpose of indirect fired water bath heater/Line heater is to prevent hydrates from forming downstream of the heater, the outlet temperature will depend on the hydrate formation temperature of gas. The coil size of a indirect fired water bath heater/Line heater is depends onn the volume of fluid forming through the coil and the required heat duty.

Vertical Heater Treater For Well Testing Industry

Vertical Heater Treater The most commonly used single-well treater is the vertical heater-treater . The vertical heater-treater consists of four major sections: Gas separation Incoming fluid enters the top of the treater into a gas separation section, where gas separates from the liquid and leaves through the gas line. . If the treater is located downstream of a separator, the gas separation section can be very small. The gas separation section should have an inlet diverter and a mist extractor. Free-water knockout The liquids flow through a down-comer to the base of the treater,which serves as a free-water knockout section. If the treater is located downstream of a free-water knockout or a three-phase separator, the bottom section can be very small. If the total well stream is to be treated,this section should be sized for 3 to 5 minutes’ retention time to allow the free water to settle out. This will minimize the amount of fuel gas needed to heat the liquid stream risi...

Chemical Injection Skid

Happy to Blog about Skid for Students ! Chemical Injection Skid are designed to inject accurate amount of various chemicals into process flow lines at a required pressure continuously or at irregular intervals SKID STRUCTURE : A Skid is basically a steel flat structure built to carry tank, pump, motor, valves, instruments and related auxillaries . The base structure of a skid is integerated with drip pan to collect the drained chemicals. CHEMICAL STORAGE TANK : The chemicals are stored in skid mounted single or multi-compartment tanks. Storage tanks are constructed in horizontal cylindrical or vertical cylindrical with flat dished bottom and top. Tanks are provided to store the chemicals , injected in the process lines. The external effects such as heat, cold, pressure, and vaccum may impact the tank ability to hold and maintain the viability of both the chemicals and container. DOSING PUMP : The Hear...

Manufacture and Supplier of 1440PSI TEST SEPARATOR sales@vienerg.com

Test Separator is one of the Key Equipment in Crude oil production Industry , which separates three phases such as Oil, Water, sand and gas from crude oil from oil well. separator skids are either manufactured in high pressures as well as low pressure. Separators are widely used in following industries such as Crude oil Well testing , Early Production Facility, Refineries, Petrochemicals and solvents industries. Separator in Upstream oil and gas industry are three phase separation and in Downstream oil and gas industry they are called as Two phsae separators. Other names for separator skids are Knock out drum, Scrubbers, Free water Ko drum, Oil separators etc
