Diseño de un sistema y equipos auxiliares para el manejo de gas de producción petrolera para la estación Sacha Norte 1.

Abstract

The purpose of this project was to dimension a system for the final separation and burning of fuel gas together with auxiliary relief, pumping and transport systems for the fluids resulting from the liquid-gas separation process at the Sacha Norte 1 station, belonging to the Campo Sacha located in the Province of Orellana, specifically in the northeastern area of Ecuador, in the Ecuadorian Amazon. The sized system is mainly made up of a KOD-type drum separator, a gas flare or flare, and a crude oil pump to return the collected fluid to the storage tanks. The related auxiliary systems comprise a set of relief valves selected for the fire contingency criteria and the sizing of process lines for the suction and discharge of the crude oil pump and for the transport of the separated gas to the flare. For this, a mass balance was initially made of the 50 active wells belonging to said station, resulting in a total of 2 280.00 MPCSD (0,75 m3/s) of fuel gas and a fluid of 17 904 BPPD as the design capacity of the new system, resulting in a Drum KOD separator with a diameter of 2.00 m and a length of 3.00 m together with a drop separator mesh as an accessory, a flare with a flare diameter of 4.00 inches and a height of 552.10 cm and a 1.36 kw crude oil pump 7 pressure relief valves and 4 process lines were dimensioned. The economic evaluation shows a required investment of USD 329 313.60 and a CAUE of USD 42 245.00 resulting in savings of 77 % of the annual costs of environmental remediation.
