Brownfield Facility Expansion – LO-CAT® Trains and Gas Treating System

Facilities

LOUISIANA

Project Overview

Evers & Sons Inc. partnered with the client to expand an existing brownfield treating facility with new equipment supporting the operation of three (3) sulfur recovery units (LO-CAT trains) and a shared chemical storage area. In addition to the LO-CAT train systems, Evers & Sons was also responsible for the installation of all gas treating and ancillary equipment required to enhance overall plant performance.

LO-CAT Train & Chemical Storage – Key Equipment (Per Train):

(1) Inlet Gas Knockout Pot
(2) Liquid Full Absorbers (LFA)
(2) LFA Recirculation Pumps (w/ Pump Seal Pots)
(1) Treated Gas Knockout Pot
(1) Treated Gas Knockout Pump (w/ Pump Seal Pot)
(1) Oxidizer
(2) Absorber Feed Pumps (w/ Pump Seal Pots)
(2) Overspray Pumps (w/ Pump Seal Pots)
(1) Solution Heater
(2) Process Air Blowers
(1) Pressure Filter
(1) Filter Box
(2) Filtrate Return Pumps (w/ Pump Seal Pots)
(3) Chemical Storage Tanks
(3) Chemical Pumps
(1) Biocide Tank with Pump
(1) Potassium Hydroxide (KOH) Storage Tank with Pump

Balance of Plant (BOP) Treating & Compression – Key Equipment:

(1) Acid Gas Screw Compressor Package (VRA 836M)
(1) Discharge Silencer
(1) Lube Oil Skid
(1) Lube Oil Cooler
(1) Seal Water Skid
(1) Acid Gas Aftercooler
(1) Injection Water Surge Vessel
(2) Injection Water Pumps
(1) LP Flare with KO Drum and Pumps
(2) CO2 Vent Scrubber Pumps
(2) Treated Water Pumps
(2) Glycol Heaters
(2) Glycol Circulation Pumps
(1) Fuel Gas Meter
(1) Fuel Gas Scrubber
(1) H2S Scavenger Injection System
(1) H2S Scavenger Tote
(2) H2S Scavenger Pumps

Scope of Work:

Concrete and structural installation for mechanical and electrical foundations
Pre-fabrication of pipe spools and structural packages
Field installation and pressure testing of all process piping
Equipment setting, including grouting of all rotating equipment
Scaffolding, coating, and insulation/jacketing

This project is designed to remove H₂S from acid gas produced by the existing amine regeneration still prior to atmospheric venting. The scope also included full balance-of-plant treating and compression installation, supporting long-term system reliability and environmental compliance.
