11 Performance Separations Separators Separators repel water droplets to guard the outlet To see if a separator has been disarmed, run a warm water test

16 Performance Separations Applications High Flow Applications Coalescer Applications –liquid-liquid –liquid-gas Refinery Applications Petrochemical Applications

17 Performance Separations HF Series – High Flow Applications HF Series Filtration Systems Hydrocarbons at Refineries Pipeline Pigging Amine at Refineries R. O. Pre-filters/Desalination Produced Water Salt Dome Leaching Removal of Black Dust in gas What to look for: Flow rates over 1000 lpm Efficiency needs

18 Performance Separations Liquid-liquid Coalescer Applications Remove water from hydrocarbon fuels such as gasoline, diesel, low sulfur diesel, kerosene/jet fuel, bio-diesel and lube oils Separate insoluble process fluids such as acids, aromatics, and esters Remove carried-over caustic, glycol, amine in hydrocarbon streams Remove hydrocarbons/oil from cooling tower water or waste water Protecting catalysts, packing or trays

19 Performance Separations Liquid-Gas Coalescer Applications 0.3um Coalescers protecting high tolerance equipment such as turbines, high effiency compressors, fuel gas burner nozzles, gas separation membranes, and absorbent beds 0.3um Coalescers and 1um Filter-Separators remove compressor lube oil, water and hydrocarbon/condensate aerosols from natural gas and process gas Carried-over glycol after dryers and/or amine after amine sweetening

20 Performance Separations Refinery Applications Common Refinery Applications – Chemflos high performance products are excellent for: –Load Out Rack –Tank Farms –Glycol –Natural Gas Filter-Separators More difficult Refinery Applications – Chemflo also has products for refinery applications where unique products are required: –Lean and Rich Amines –Caustic Treating –Alkylate –Reformate –Low Sulfur Diesel

21 Performance Separations Refinery Applications Common Refinery Applications – Chemflos high performance products are excellent for: –Load Out Rack –Tank Farms –Glycol –Natural Gas Filter-Separators More difficult Refinery Applications – Chemflo also has products for applications where common products fail: –Lean and Rich Amines –Caustic Treating –Alkylate –Reformate –Low Sulfur Diesel

22 Performance Separations Sweetening Sweeting is the removal of sufur acid compounds found in hydrocarbons often called: Hydrogen Sulfide (H 2 S) or Mercaptans The main types of process equipment in sweetening systems are called: Amine Hydrotreaters Caustic Treatment (Merox Process) Sulfur Recovery Units (Claus Unit)

23 Performance Separations Amine Sweetening

24 Performance Separations Amine Sweetening Amine Systems –sweeten natural gas and remove CO2 Amine Systems are a closed loop system so contaminants build up over time in the system Main contaminants over time are iron sulfides Improved filtration can cause fewer upsets, less amine losses and lower amine concentrations CHEMFLO recommends 100% Filtration at 10um absolute or tighter

25 Performance Separations Amine Sweetening Rich Amine – after the contactor –can have a hydrocarbon content to high for polypropylene Lean Amine – after the exchanger – can have temperatures too high for polypropylene Common Types of Ethanolamine's –Mono-ethanolamine (MEA), Di-ethanolamine (DEA), Mono-diethanolamine (MDEA) Other types of solvents (less common) –Selexol, Rectisol, Purisol

26 Performance Separations Hydrotreater - naphtha HYDROTREATING naphtha FROM DISTILLATION ISOMERIZATION CATALYTIC REFORMING Fuel Gas Naphthas have an aromatic content that dissolves many common filter and coalescer materials over time

27 Performance Separations Caustic Treating - Merox Process The Merox Process is a common Caustic sweetening process developed by UOP

28 Performance Separations Caustic Treating Sodium Hydroxide sweetens liquid hydrocarbons Caustic is most commonly used to sweeten: –Kerosene (jet fuel) –LPGs –Light Naphthas (commonly used in ethylene production) Caustic reacts with many common filter materials including polyester, phenolics, glass fiber, urethane adhesives, aluminum and carbon steel. Coalescers remove carried over caustic by removing water downstream of caustic washes Caustic lowers interfacial tensions substantially causing emulsions that are difficult to remove

29 Performance Separations Catalytic Reforming Unit Conversion of Low Octane Petroleum Refinery naphtha Feedstock to High Octane Gasoline (Petrol) Products. Other byproducts include methane, ethane, propane and butanes.

30 Performance Separations Catalytic Reforming Unit Reformate is added to gasoline to boost octane and to get more of the crude distillate into gasoline The Catalytic Reformer converts naphtha, usually heavy naphtha, into reformate. The aromatic content in reformate attacks many common filter and coalescer materials including common adhesives, common glass fiber binders and cellulose/paper medias.

31 Performance Separations Akylation Process whereby isobutane combine with light olefins in the presence of a strong acid catalyst to produce a high octane alkylate Hydrofluoric Alkylation Process

32 Performance Separations Akylation Commonly called the alky unit Alkylate is added to gasoline to boost octane and to get more crude distillate converted into gasoline (similar to reformate) The feed stock is isobutane and propylene/butylene but usually we are asked to filter or coalesce either isobutane or isobutylene The Alky unit uses either a HF(hydroflouric acid) or sulfuric acid catalyst The combination of acid carryover and isobutylene is a very aggressive solvent and dissolves many common filter materials

33 Performance Separations Low Sulfur Diesel Commonly called the Green Diesel or ULSD (Ultrao Low Sulfur Diesel) There have been huge investments by diesel refiners to add hydrotreaters to reduce sulfur content of diesel because of government regulations across the world Low Sulfur diesel can have low interfacial tensions causing coalescers not to work well unless designed for low IFTS Low Sulfur Diesel and especially ultra low sulfur diesel is a powerful solvent and attacks cellulose, binder in common glass fiber filters/coalescer and many adhesives
