Client Description Waste-Management Education and Research Consortium (WERC)  Typically, the environmental tasks have no known solution or the available solutions do not meet performance criteria 3 Ali Hasan The goal of the competition is to design, develop, and test actual environmental processes for real-world problems.

Problem Statement  Task:  Emulsion techniques  Separate emulsified oil in water  Design:  Cost effective  Efficient  Robust  Ideal solution:  High degree of separation  100% water 0% oil  100% oil 0% water 4 Ali Hasan Non-emulsion Vs. Emulsion

Project Significance 5  Increased use of petroleum creates a need to remove emulsified oil from water before disposal  This project removes oil contaminants from the water  Safer and cheaper to dispose  Recovers oil

Needs Statement  Full Scale Model:  100 GPM  Uses industrial waste oil  Uses brackish water  Bench Scale:  Emulsified vegetable oil  Represents the industrial waste oil in full scale  Environmental Health and Safety (EHS) disposal Given:  10 gallons of emulsified oil-water solution 200 mg/L concentration  Must obtain one gallon of separated water and 8 ml of oil 6 Ali Hasan

Preliminary Research: Emulsion  Physical Emulsion  Shearing Power  Chemical Emulsion  Emulsification Agent  Sound Energy  Sonicator 7 Christina Holt Sonicator

Emulsion Techniques for Bench Scale Vitamix 7500  ~2.2 horsepower motor  120 V or 12 A  23,000 RPM  Can boil water in under 10 minutes  Cost: $500 8 Christina Holt

Preliminary Research: Separation  Physical Separation  Plate Separation  Electrical Separation  Electrocoagulation  Chemical Separation  Coagulation and Flocculation  Gas Injection System 9 Christina Holt Physical Separation Electrical Separation

Overall System 10 Gas Injection Tanks Coagulation & Flocculation Chemical Injection Storage Tank Mahdi Mohammad

Storage Tank  16,000 gallon storage tank will accommodate flows up to 130GPM for 2 hours. 11 Mahdi Mohammad * All the dimensions are in inches

Coagulation and Flocculation System  Best Chemical?  Chemical: Ferric Sulphate  Dose = 30mg/L  Amount: kg/day  0.2 gram every second 12 Mahdi Mohammad

Coagulation and Flocculation System 13 Mahdi Mohammad Dry Chemical Injection Coagulation & Flocculation * All the dimensions are in inches

Gas Injection System 14 Daniel Pardo  3 gas injection tanks : 1 coagulation system  When 3rd tank is ½ full, 1st tank ready for more emulsion

Gas Injection Tank 15 Daniel Pardo Multiple Gas Spargers Water Exit Oil Exit Valve * All the dimensions are in inches  Compressed Nitrogen Gas  Small Bubble Size  Oil Layer (25 mm = 1inch)  Collection

Bench Scale 16 Daniel Pardo Gas Injection Tank Coagulation and Flocculation System  Coagulation  2 minutes rapid  5 minutes slow  Gas Injection  45 Minutes

Competition Results  NMSU Chemical Team  Clean water  No oil found in water sample  Minimum oil recovery  Losses occurred during transfers  7 Teams  Only first and second announced 17 Daniel Pardo

Analysis 18 Daniel Pardo Stage 1: Emulsion Stage 2: Coagulation System Stage 3: Gas Injection System  Head losses  No overflow  Oil particle size  1. Emulsion Stage  2. Coagulation  3. Gas Injection  Confirms oil will separate
