Crude oil residual brines contain salts that can cause serious corrosion and scaling problems and must be removed. Desalination removes salt and residual free water. Although the refinery is the most economical desalination place, it is usually required to enter the oil production site for desalination treatment from the perspective of pipeline protection.

Challenge:

Level gauges are an integral part of settling tanks for single and dual stage desalination systems, perforated plate mixers and chemical desalters. Interface level control prevents free water from reaching the desalination electrodes and prevents high damage. The interface level should be kept constant, otherwise changes in the electric field will interfere with electron coalescence.

LC series intelligent displacer liquid (boundary) level transmitter

LC series displacer type liquid level gauge is designed according to the principle of Archimedes buoyancy, and is used to measure liquid level, interface and density of liquid. It has high measurement stability, especially suitable for liquid level/interface measurement occasions with small range, high temperature, high pressure, and low density, and can meet the interface measurement with small medium density difference. The transmitter can conveniently perform remote configuration and management (monitoring) of the transmitter through the HART communication protocol, using a PC or a general-purpose handheld terminal, and can also be operated with conventional local keys.

Features:

● Double SIL 2 certification of France BV and Shanghai SITIIAS.

● Provides 4-20 mA and with HART, 475 Field Communicator for on-site configuration, calibration and diagnostics.

● Comprehensive fault diagnosis, warning and status history.

● PED pressure vessel certification that meets the requirements of the European Union, and the applicable pressure can reach up to 42MPa.

● Can be used in non-steam applications up to a maximum process temperature of 500°C.

● CSA, ATEX and IEC explosion-proof, intrinsically safe certification.

● Process parameters can be adjusted online.

● The meter head of the transmitter can be switched freely in 8 directions without affecting the on-site process.

● Suitable for interface measurement and density detection.

● (EMC) EU Electromagnetic Compatibility Directive CE certification.
