Liquid and gas inlet devices

Spliteks manufactures liquid and gas inlet devices based on the best engineering traditions of Sulzer Chemtech. These internals are designed to introduce and distribute streams efficiently in mass-transfer equipment, ensuring stable process operation in the oil and gas and chemical industries.

Purpose and operating principle

Liquid and gas inlet devices perform several functions at once: uniform flow distribution across the column cross-section, preliminary phase separation, momentum dissipation and foam suppression.

Their operating principle is based on optimising the direction and velocity of the incoming flow. Special designs prevent the jet from striking the packing or trays directly, minimise liquid entrainment and ensure uniform irrigation of the contact elements. This is particularly important under variable flow-rate and high-pressure conditions.

Types and designs of devices

Spliteks offers various types of device adapted to specific operating conditions. The main designs include:

• Inlet manifolds with deflectors for dissipating flow energy.

• Distribution devices with perforated pipes for uniform liquid introduction.

• Combined assemblies integrating inlet and preliminary gas-liquid separation functions.

All devices are designed for the vessel diameter, operating pressure and properties of the process medium. The designs comply with GOST requirements and provide minimal hydraulic resistance.

Use in industrial processes

Liquid and gas inlet devices operate successfully in a wide range of equipment:

• Distillation and stripping columns.

• Absorbers and scrubbers.

• Gas separators and stabilisers.

• Gas dehydration units and other mass-transfer equipment.

In columns, these devices prevent damage to the packing bed, reduce the likelihood of flooding and increase mass-transfer efficiency. They are particularly effective for introducing two-phase streams, where rapid, uniform distribution of vapour and liquid is required.

Manufacture and supply

Its own manufacturing facilities in Serpukhov enable devices to be manufactured to the customer’s individual parameters, including column diameter, process type, material and operating conditions. Each assembly undergoes quality control and hydraulic testing.

Liquid and gas inlet devices can be purchased directly from the manufacturer. Spliteks arranges prompt delivery throughout Russia with a complete set of technical documentation. The company’s specialists help select the optimum solution for the specific process configuration.

Spliteks liquid and gas inlet devices are reliable components of modern columns that increase separation-process efficiency, reduce operating risks and ensure the stable operation of all process equipment.
