Case Study

Using PipelineStudio from ESI, Transierra S.A.has successfully planned and optimized a capacity expansion for a critical natural gas pipeline:

Margarita Natural gas field output is connected through a 10 “ set line (17km) with Sabalo GASAN gas field export lines 28 “OD (20 km) , which goes to Villamontes GASYRG compressor station (MOP 1440 psig) and is connected with Yabog.

“Gasan” Maximun Transport Capacity

The maximum design transport capacity is 21 MMCDΦ ¢o achieve ǘƘƛǎΣ ŀƴ ƻutput pressure of 1080 Psi (Sabalo) ƛǎ NJŜljdzƛNJŜŘ and arrival pressure of 1030 Psig (Villamontes) ŀs showƴ in the simulation below.

Capacity Expansion for Transportation Project - San Antonio’s Project, Bolivia

Current Transportation System

Transport Capacity with System Compression Booster

Average Volume Margarita = 1.43 Mmcd Average Volume San Antonio = 13.39 Mmcd total Volume SAN + MGT = 14.82 Mmcd Pressure out San Antonio = 1080 psig Pressure in Villamontes = 1030 psig

To increase transport volume and meet the GTCS, we propose the following alternatives based on simulation: 1. Independent booster system 2. Integrated booster system 3. Loop +booster independent/integer

Installing a booster compression system, at operating conditions of: * Suction Pressure = 850-900 Psig * Discharge Pressure = 1030 Psig * Sabalo Pressure = 1073 Psig * Required Power (Approx.) = 8400 Hp is reached at 34 Mmcd Transport Capacity.

Transport System’s Simulation, Using Pipeline Studio, Ver. 3.1

Gasan with Loop 28 Mmcd

As has been mentioned beforeΣ ƛǘ is required ǘƻ build a 7Km Loop and 28 OD to increase the transport capacity.

The simulation shows that, to achieve an arrival Pressure of 979/940 Psig (Villamontes) with a 34 Mmcd Flow and an output pressure 1050/1080 Psig (Sabalo Gas Plant), it is necessary to use compression for this volume, because the conditions of delivery required are not achieved at this point.

The simulation shows that, to achieve an arrival pressure of 1036 Psig (Villamontes) with a 28 Mmcd Flow and an output pressure 1080 Psig (Sabalo Gas Plant), it is not necessary to use compression for this volume, because the conditions of delivery are achieved at this point.

The simulation shows that, to achieve an arrival Pressure of 1030 Psig (Villamontes) with a 34 Mmcd Flow and an output pressure 1080 Psig (Sabalo Gas Plant), it is necessary to use a system compression booster with a power of 3000 Hp.
