Zeta-pdm Ltd

Sand Jet Systems

We supply a fantastic range of cost effective sand jet systems which are widely used with horizontal separators. When the bulk of produced solids accumulates in the primary gravity oil-gas separator vessel it must be cleared periodically. Our sand jet systems use little water but provide a powerful tool for this purpose. They are supplied at competitive prices and are designed to be tough and reliable for regular re-use. Please visit our website to find out more about our sand jet systems or contact us at Zeta pdm Ltd for further information.

Inlet Devices

We also offer a complete range of traditional inlet devices as well as many proprietary inlet devices of advanced design. Our products include:

• ZP-4G Inlet Cyclone
• ZP-Vane Type Inlet Device
• ZPV Rainmaker Inlet Device
• ZSQ Squirrel Inlet Device

As well as resulting in reduced capital expenditure (CAPEX) and operating expenditure (OPEX), the advantages of using the optimum inlet device for a particular application include:

• Minimised inlet nozzle and upstream piping size

• Lower feed stream momentum and minimised droplet shatter

• Prevention of liquid / liquid interface mixing and prevention of liquid re-entrainment from the gas / liquid interface

• Separation of "bulk" liquids and de-foamed incoming fluid

• Proper distribution of liquid and gas to downstream equipment

Gas-Liquid Coalescing Devices

Separating the smallest liquid droplets from the gas stream is difficult, as the required velocity may be higher than that above which liquid re-entrainment will occur. The installation of a pre-conditioner or coalescing device upstream of the demister is a frequent solution to this problem.

We offer two types of coalescing devices, Mesh Type and ZP-090 Vane Type systems, both of which operate as a coalescing device in a flooded condition at approximately three times normal design velocity. This enlarges the liquid droplets within the device, enabling the downstream demisting device to more easily separate them, and substantially improving gas / liquid separation efficiency.
