Woven Mesh
Structured Packings & Random Packings

1.Structured Packings

Features
  • Structured packings usually offer less pressure drop and have higher efficiency and capacity than random packings.
  • The corrugated metal sheets of structured packings are arranged to create flow channels for the vapor phase.

QWP MAKE STRUCTURED PACKINGS are effectively used for separation application in the Gas Processing Plants, Chemical Processing Industries and in the Oil & Gas industries typically for separation applications.

Non-Metal Structured Packing
  • PVC, PP, PVDF & Teflon – Non metallic Structured Packings

Our in house process engineers design and supply various types of Structured Packing’s depending upon the requirements along with support bed and other internals according to the needs of the end user.

Metal Structured Packing
  • Wire Mesh Gauze Structured Packing
  • Sheet Metal Structured Packing in Carbon Steel, Stainless Steel and in Nickel Alloys
Types of structured packings
  1. Metal Based Structured Packings
    • QWP Type 1
    • QWP Type 2
    • QWP Type 3
    • QWP Type 4
  2. Plastic Based Structured Packings
    • QWP Type 5
  3. Ceramic Based Structured Packings
    • QWP Type 6
Advantages of structured packings as compared to the use of random packing and trays
  • Lower pressure drop.
  • Higher efficiency.
  • Higher capacity.
  • Reduced liquid hold-up.
  • Excellent liquid spreading characteristics.

2.Random Packings

Features
  • Random packings are inexpensive but efficient option to increase a tower’s capacity and/or efficiency.
  • The main reasons for using tower packings are:
    – to reduce pressure drop throughout the column.
    – to increase the contact surface.
    – to reduce liquid holdup in the column.

Quality Wire offers the following packing internals which are used in the refinery and gas processing industry and mass transfer applications.

a. QWP Progressive Metal Packing

Quality Wire Progressive Metal Packing (QWPMP) is made of metal sheets and give the best performance with relation to low pressure drop and high efficiency. These Packings are made in progressive die tool with complete precision to ensure the best quality. Common sizes available is 12, 25, 40, 50 & 70.

b. QWP Q – PAK Metal Packing

Q-Pak is also a progressive die tool products and Q Pak is an excellent improvisation of the traditional pall rings and is considered the most efficient ring type packing. With more numbers of internal strips, the interactive areas increases for gas liquid contact, so these type of rings maintain the efficiency of packing when compared to normal pall rings. With the same efficiency it gives lower pressure drop than pall ring. Due to the special design the thickness of the rings are reduced, reducing investment costs while replacing pall rings with the same.

c. QWP Pall Rings

Traditional Pall Rings are simple rings with no internal strips mostly used as replacement tolls. They are available in metal, plastic and ceramic. These rings are used in the heat transfer applications, absorbers,scrubbing and stripper.

d. QWP Carbon Raschig Rings

Raschig Rings are made from Carbon or Graphite used in specific applications to withstand good corrosion and thermal shock resistance. They are resistant to most acids, alkalis and solvents at high temperature and also display good erosion and thermal stock resistance. At the same time, they have high crushing strength and thus have a long life. They are available in variable sizes such as 10mm, 19mm, 50mm & 75mm.
