Air Pollution & Wastewater Experience for Refineries and Petrochemical Plants in the Gulf Coast Region

Refineries, Chemical, and Petrochemical plants use significant amounts of water in their processes. Water consumption can be reduced by optimizing and improving the efficiency of a plant’s water and wastewater treatment processes, as well as its wet scrubbing and water consuming applications for air pollution control.

Consider these findings from independent studies:

  • Oil refineries use about 1 to 2.5 gallons of water for every gallon of product produced. United States, which refines nearly 800 million gallons of petroleum products per day, consumes about 1 to 2 billion gallons of water each day to produce fuel (USDOE, 2006).
  • According to the United Nations, the energy sector is responsible for approximately 15 percent of global water withdrawals, making the reduction, reuse and mitigation of water a top priority.

multi-stage-scrubber-for-chemical-plant

Two-stage Wet Scrubber with C-276 hastelloy Quench Tower and FRP Packed Tower to remove HF from gas stream at a chemical plant using KOH. The systems included integral scrubber sump, recirculation pump, piping, instruments, valves, and supports for hurricane wind speeds.

Wastewater treatment Clarifier

API Separator to remove free oils and solids from plant runoff wastewater at an aviation lubricants plant in Louisiana. The system included an energy dissipating influent, solids collection and surface skimming conveyors, and was rated for 100 GPM.

API 421 standards, 140ft. long API Separator

API 421 standards, 140 ft. long API Separator rated for 900 GPM for primary oil water separation and solids removal from refinery wastewater.

Horizontal Clarifier for PVC plant wastewater

Cost-effective expansion of manufacturing capacity via wastewater reclamation and re-use: 600 GPM Horizontal Clarifier to separate suspended solids from wastewater for a PVC resin manufacturing plant. Read More

Lamella Plate Clarifier For Metal Hydroxide Reduction

660 GPM Lamella Plate Vertical Clarifier for the reduction of cobalt hydroxides from a process water stream at a petrochemical plant. Read More

vertical-clarifier-rebuild--before-after

Retrofit of two Lamella-type Plate Clarifiers at a chemical plant. A competitor’s clarifier was insufficiently designed to handle process temperatures and was warping and buckling, causing safety and process hazards. Monroe gutted the clarifier and installed new supports and plates to allow the unit to operate properly, saving the plant over $200,000 versus replacing the clarifier. Read More

Quench TowerWet Scrubber with high temperature Quench Tower to remove SO2 from the combustion exhaust. The system was designed to treat 27,000 ACFM at 800°F and achieve +99% SO2 removal efficiency. Read More
