Sediment Extraction Apparatus for Petroleum

Electrometric Salt Determinator

The Salt in Crude Analyzer determines the salt content, conductance, and temperature of crude oil samples according to ASTM D3230 and IP 265 specifications. Salt content is determined by measuring the conductivity of a solution of crude oil in a polar solvent when subjected to an alternating electrical current and is obtained by comparison of the resulting conductance to a calibration curve of known salt mixtures.

Utilizes the latest low-voltage, synchronous detection technology for conductivity measurements and a high-accuracy thermistor array to measure sample temperature. Automatically calculates salt concentration directly from acquired temperature and conductivity values. Measures conductivity over four ranges 0-2, 2-20, 20-200, and 200-1500 mS with automatic range selection.

Sediment Extraction Apparatus

The Sediment Extraction Apparatus determines sediment content of crude oil and fuel oils by extraction with toluene. A test portion of the sample is placed in a refractory thimble. Toluene is gently boiled and its vapors condensed and allowed to drip into the sample funnel. The toluene washes out all of the crude oil or fuel oil leaving the insoluble residue only in the thimble. The mass of the residue is calculated as a percentage and is referred to as the sediment by extraction.

Features

• Conforms to ASTM D473 and related specifications
• Includes condenser thimble basket, water cup and extraction thimble

Specifications

Conforms to the specifications of: ASTM D473; IP 53; ISO 3735; DIN 51789; FTM 791-3002; NF M 07-010
