Glycol Dehydration Unit Operation

Glycol Dehydration Unit Operation

Glycol Dehydration Unit Operation | Process Flow Diagram

 Better dehydration results and significant saving are achieved when dehydration systems are operated properly. Efficiently operated glycol dehydration systems require good understanding of dehydration process, process variables and dew point. We must also understand the operations of the individual components within the system.

Inlet Gas Separator
Let’s start with the inlet separator. The inlet gas stream first enters the gas dehydration unit through an inlet gas separator. Here free liquids are removed, wet gas leave the separator through a mist eliminator. Which eliminate almost all carrier free liquids to the contactor column.

                                                                 Daily Check-up
The inlet separator should check regularly. Overloading the inlet separator causes excess liquid carrier over into the contactor column which cause foaming. Therefore for proper operation it is important to rotationally monitor liquid levels and there controls.

FLASH TANK(Gas Condensate Glycol Separator)

Image
Gas Condensate Glycol Separator (Flash Tank) The gas condensate glycol separator also known as flash tank or glycol gas separator. Remove gas and liquid hydrocarbons carried out the contactor by the glycol solution. The gas leaves from the top of the vessel and is vented or may be supplement to use the fuel gas required for the re-boiler. Pressure relief valve A pressure control valve maintains the back pressure on the vessel usually 50 to 85 psig (345 to 587 kpa) any excess gas is discharge through this back pressure valve. Advantages of Separating of Hydrocarbons from Glycol Separating liquid hydrocarbons from glycol before they enter the re-boiler provided several benefits. Reduce load on carbon filter. Prevents carbon buildup on the fire tube. Prevents glycol contamination in glycol still column. Which can result in flooding, glycol losses and possibly damage to the column. Control Systems on Flash Tank Two level control systems are typically install

CONTACTOR COLUMN (Absorption Column)

Image
Contactor Column The function of the contactor column, also called absorber, is to remove water vapor from natural gas by physically bringing together. The up flowing natural gas with the down flowing glycol solution. The glycol absorbs the water vapor from the natural gas.                                                                  Design Specifications Contactor column are design to accommodate certain gas volume and pressure, if these design specification are exceeded, then glycol losses and outlet gas dew point will increase. Contactor column usually contain either Trays Random packing Structural packing Contactor at Nandpur field contain structure packing. Structure packing is group of core gadded metal sheets welded into a specific pattern and place on edge in the contactor. Glycol coats these sheets and the gas flow between them. This type of packing is more efficient than bubble caps or random packing. Structure is used in c

TYPICAL CONDITION WHICH EFFECT GLYCOL LOSSES

Image
Typical Condition Which Effect Glycol Losses Carryover with outlet gas leaving the contactor. Leaks at the pump or pipe fittings. High still overhead temperature. Contactor column operating at excess gas rates. Foaming. Rapid changes in the gas rate. But Who do we know if our system operating efficiently or not. Well, we take glycol samples in the field have lab test them, in term of the results then you make the necessary adjustments to reach maximum drying efficiency. Now we can find out by analyzing the glycol, now it can tell us Glycol weight percentage Water content Hydrocarbon content Salt contaminant Solids contaminant The pH of glycol Iron content Foaming tendencies Glycol weight Percentage The glycol weight percentage reefer’s to the amount of glycol in the glycol solution also known as glycol purity. Lean glycol should contain about 98.5 to 99.9% glycol. Rich glycol content varies about 93 to 96% glycol. Let’s assume rich glycol sample is i
