Sediment Extraction Apparatus

Description

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. Includes the condenser thimble basket, water cup and extraction thimble.

Test Method

Determines sediment content of crude oil and fuel oils by extraction with toluene.

Features
