Manufactured in corrosion resistant ceramics, Ceramic Structured Packing is an economical alternative to exotic metals and engineered plastics, and provides excellent service life in most corrosive applications.

our proprietary ceramic structured packing is constructed of corrugated sheets of ceramic. The angle of inclination of the corrugations of adjacent sheets is reversed with respect to the vertical column axis, forming mixing cells at every point where the corrugation intersect. This promotes intimate mixing and radial distribution of the liquid and gas streams. Each subsequent element is rotated about the column axis so that the sheets of one element are opposed to the sheets of the elements above and below. In passing through each element, gas and liquid are thoroughly mixed in the direction parallel to the plane of the sheets. By rotating subsequent elements, excellent mixing and spreading, both side to side and front to back are obtained over the entire cross section of the tower. The flow characteristics developed by the structured geometrical arrangement creates high effective surface area resulting in good efficiency as compared to other mass transfer devices. Improved hydraulic performance of our structured packing result from the corrugated sheets being vertically oriented, eliminating any horizontal surfaces which create resistance to fluid flow. As a result, towers packed with our structured packing have a very low pressure drop and a corresponding higher capacity.

Our structured packing system stands up to the toughest operating environments whether applying the technology to retrofits, upgrades or new construction, our professionals draw on an accumulated body of knowledge that nobody else can offer: more installations, more years of experience, more technical expertise than any other supplier.

Unique features of  ceramic structured packing system provide significant benefits over traditional random packing

---

• Geometric Design- Effectively minimizes channeling and radically distributes gas and liquid uniformly over the tower cross section.
• Rigid Construction- Significantly less breakage and fouling of downstream equipment normally associated with random ceramic packing.
• Natural Wettability- Improve film formation for high surface tension aqueous liquids enhance efficiency.
• Higher Capacity- Increase flow to existing towers or reduce diameters of new tower designs.
• Lower Pressure Drop- Lower energy costs without sacrificing capacity

Like sieve trays, valve trays have been in use as far back as the 1950’s but nowadays have become the more popular choice because of their greater operating range properties. With our technical expertise in design, manufacturing, and installation, a well designed valve tray generally provides the most economically attractive solution for grassroots column construction projects. Valve trays combine high capacity and excellent efficiency with a wide operating range. Using proprietary design techniques and wide range of valve types available for valve trays, design engineers at Saiptech can assist you in optimizing performance for your application.

Material of Construction

Fractionation trays are fabricated from a wide variety of materials. When corrosion is expected to be extremely low and design temperatures are not excessive, carbon steel is a logical choice because of its favorable mechanical design properties, malleability and low cost. However, since the material of construction is dictated by the process of each particular system for which the trays will be used many different material types may be required because of unique properties which allow some mate to have resistance to corrosion and to maintain their mechanical strength at elevated temperatures.
The most common tray materials that Saiptech utilizes are listed below starting from least expensive:

• Carbon steel
• Stainless steel: 410s/304/316L/321/904L
• 2205/2507 Duplex Steel
• Titanium
• Zirconium
  
• Monel 400
• Hastelloy C276

Bubble cap trays are used primarily in applications with very low liquid loading and very high flexibility, where large turndown ratios are required. it usually have a lower capacity (10%-20%) than properly designed valve or sieve trays; however, they are capable of efficient performance over a wider operating range due to their superior leak proof characteristics.

Saiptech designs and provides a variety of bubble cap trays in which are the most leak free trays available. Our most common bubble cap designs include conventional slotted caps (some have slots for vapor passage and others do not). Of course, custom designs are available as well. The potential mechanical configurations for the various riser and cap assemblies are numerous . Typical manufacturing methods to secure the riser and cap assembly to the tray floor include seal welding, press fitting, through bolting and swaging riser into extruded opening.

Bubble Cap Types Available

• Round type--Size 3",4",6", also tailor made

• Tunnel type--Thormann Tray

• Plastic type--PP, PVDF

• Cast Iron

• Copper

SPT mesh pad type demister remove droplets by impingement on the wire surface. The liquid collected on the filaments is then able to drain from the pad under gravity. They have a limited range of useful operation in which they provide almost complete removal of droplets down to about 3-5 microns. Turndown range of the vapour rate is around 3:1. At excessively high vapour velocities, the liquid droplets that impinge on the wire surface are sheared off by the vapour and re-entrained before they are able to drain. At very low vapour velocities, all but the larger droplets are able to follow the vapour path through the mesh and thus avoid impingement; however the inherent design of the separator vessel means that in most applications an effective turndown performance of 10:1 or better can be achieved.

Wire mesh demisters are well suited to remove mechanically formed entrainment from packed and trayed process towers, spray columns, venturi scrubbers and other gas scrubbing devices. They are also a widely used de-entrainment device in knock out drums and separators. With its superior design, Saiptech has developed a serious of mesh type mist eliminators depending on direction of gas flow and the complexity of the vane profile.

Manufactured in virtually any size from a wide range of material, over 14 different styles can be designed and fabricated.
