Vepica's Downstream Experience

Apr 15, 2019 6:00:00 AM / by Vepica Corporate


The downstream oil sector involves the refining of crude oil and the sale and distribution of natural gas and products derived from crude oil. Over the last ten years, Vepica has developed and executed the following projects in this sector:


PROJECT NAME: Davis Refinery North Dakota

CLIENT: Meridian Energy Group

SCOPE: Engineering studies

HIGHLIGHTS: Engineering studies to define the design basis, costs and schedule for the Davis Refinery, a high-conversion crude oil refinery to be constructed in southwestern North Dakota to serve Bakken crude oil producers and local liquid fuels and chemicals markets. Upon completion of these studies, Meridian, with BASIC’s and Vepica’s support, will complete the permitting and approval requirements, finalize full project financing, and make final announcements regarding the commencement of detailed design, procurement, construction and start-up of the Davis Refinery

Completed in 2015


PROJECT NAME: Crude Fractionation Facilities

CLIENT: Petromax Ref. – Sunoco Logistics

SCOPE: Basic Engineering / Detail Engineering

HIGHLIGHTS: Project scope included the design of new Crude Fractionation facilities to process 25,000 BSPD of light crude (API 38.2° or API 45.8°). The facilities will handle single crude streams or a combination of these two feedstock mixed at any ratio.

Fractionation facilities consisted of an Atmospheric Distillation Unit (ADU) designed to process 25,000 BSPD and to provide products run to storage facilities, along with the utilities required to support the proper and safe operation of the process systems.

Completed in 2015


PROJECT NAME: Technical assistance for El Palito Refinery


SCOPE: Technical assistance services

HIGHLIGHTS: Technical assistance services in all disciplines for El Palito Refinery included:

  • Compressed air Merox process for olefins and gasoline Merox units.
  • Update safety relief valves (for the end of 2009 plant maintenance)
  • Cathodic protection system
  • Assistance in detail engineering for power plants La Cabrera and El Palito
  • Operations control room and storage facilities for diesel power generators (8 units for a total of 15 MW)
  • Improvements in warehouses, roads and parking lighting admitted. Section Q.
  • Improved rainwater drains
  • Installation of two boilers
  • Access to marine terminal
  • Extension CCTV systems, ACS and SDI
  • Technical assistance for various social projects developed by PDVSA in neighboring communities (clinical, sports facilities, urban planning).

Completed in 2011


PROJECT NAME: Santa Inés Refinery


SCOPE: Conceptual and basic engineering

HIGHLIGHTS: The refinery will have a 60,000 BPSD capacity for processing Guafita crude (24 - 28.8 °API) for the production of gasoline (regular and premium), diesel, jet fuel (A-1), LPG, fuel oil and asphalt. The new refinery will be located in Barinas State, Venezuela.

Vepica’s scope covers the following facilities:

  • Asphalt production
  • Sour Water Stripper:
  • Amines plant
  • Utilities: raw water supply and treatment, compressed air (services and instruments), N2 system, storage facilities, dispatch facilities, firefighting System, chemicals injection Package.
  • Electric system: electric facilities buildings, grounding, lightning protection, lighting.
  • All buildings
  • Route study, ports and transport
  • Crude oil pipelines and gas pipelines
  • Water and sewage pipelines
  • Electrical ducts

Completed in 2010


PROJECT NAME: Deep Conversion Puerto La Cruz Refinery


SCOPE: FEED, detailed engineering, procurement management, construction management, start-up assistance

HIGHLIGHTS: The project’s objective is to increase the Refinery’s capacity to process heavy and extra heavy oils from the Orinoco Oil Belt, using PDVSA/ INTEVEP HDHPLUS / SHP proprietary technology.

This will be achieved through the revamp of two atmospheric distillation units (DA-1 y DA-2) in order to process 170 MBD of Merey heavy crude (16º.API). The project includes new process units, utilities and off-sites:

  • Vacuum distillation: 117,000 BPSD (total for 2 trains)
  • HDHPLUS ® 50,000 BPSD (total for 2 trains)
  • SHP: 100,000 BPSD (total for 2 trains)
  • Additional production: 127 TPD
  • Residue process / flakes solidification 554 TPD
  • (total for two trains)
  • Gas recovery: 36,741 BPSD
  • Hydrogen production:230 MMSCFD
  • Hydrogen recovery: 122 MMSCFD
  • Hydrogen compression: 314 MMSCFD
  • Sour water stripper: 1,553 GPM
  • Amine regeneration: 1,573 GPM
  • Sulfur Recovery & Tail Gas Treatment: 426 TPD

Completed in 2010


PROJECT NAME: El Palito Refinery Expansion Project

CLIENT: Y&V Ingeniería / PDVSA

SCOPE: Procurement, detailed and basic engineering

HIGHLIGHTS: Capacity improvement to 140,000 bbl/d.  Revamp and installation of the following units:

  • Atmospheric distillation units revamp to process an increased volume of heavy and extra heavy oil, consisting in a 22o API mixture formed by Mesa 30 and Merey 16
  • New Naphtha Hydrotreating Unit to reduce the S and N2 content to 0.5 ppm max
  • New CCR Unit (Fluidized Catalytic Reforming Unit) for naphtha reforming, improving the RON Number to 100 as a minimum
  • The Distillates Treatment Plant involves a new Diesel Hydrotreating Unit for cetane No. improvement to 51 and S reduction to max. 7 ppm.wt
  • Deep Conversion Plant: new HDHPLUS/SHP plant for Hydroconvertion and Hydrotreating to transform the vacuum residue in commercial products and to produce a VGO

Completed in 2010
