SURGE TANK & PUMP

Surge Tank or Accumulator

Now the surge tank store regenerated glycol for pump suction and it is commonly position under the re-boiler. Vapor which are trapped in the surge tank could cause circular pump to vapor lock. Therefore a vent line is provided to remove these vapors from the surge tank.

Pump

  • Most small dehydration unit used a fluid driven pump (Nandpur Field).
  • Larger units generally used electrical driven reciprocating pumps in either case.
 The pump is a critical part of the unit because it has the only moving part in the system.
Pump Safety
Now before the rich glycol enters the pump it passes through a strainer to remove large particles leaks can be a problem around glycol column pumps. Proper packing land maintance and use the manufacture recommended packing can minimize this problem.

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
