  • Common Refinery Applications – Chemflo’s high performance products are excellent for:
    • Load Out Rack
    • Tank Farms
    • Glycol
    • Natural Gas Filter-Separators

Refinery Applications
  • Common Refinery Applications – Chemflo’s 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
sweetening
Sweetening

Sweeting is the removal of sufur acid compounds found in hydrocarbons often called:

  • Hydrogen Sulfide (H2S) or
  • Mercaptans

The main types of process equipment in sweetening systems are called:

  • Amine
  • Hydrotreaters
  • Caustic Treatment (Merox Process)
  • Sulfur Recovery Units (Claus Unit)
amine sweetening1
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
amine sweetening2
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

Fuel Gas

naphtha FROM DISTILLATION

ISOMERIZATION

HYDROTREATING

CATALYTIC REFORMING

Naphthas have an aromatic content that dissolves many common filter and coalescer materials over time

caustic treating merox process
Caustic Treating - Merox Process

The Merox Process is a common Caustic sweetening process developed by UOP

caustic treating
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
catalytic reforming unit
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.

catalytic reforming unit1
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.
akylation
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

akylation1
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
low sulfur diesel
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
chemical and petrochemical processes
Chemical and Petrochemical Processes
  • Vinyl Chloride Monomer (VCM) Process
  • Hydrogen Peroxide
