Abstract

The invention discloses a device and method for detecting heated coke formation propensity of a solid heavy raw material. The device comprises a sealed box. A sample pool is arranged in the sealed box. A heater for heating the sample pool is arranged outside the sample pool. A suspended heating device for providing heat for the solid heavy raw material is arranged in the sample pool. A sleeve for adsorbing coke particles is arranged outside the heating device. The top of the sleeve is connected with a weighing device. The weighing device measures the quality of the electric heating bar sleeve and the quality change, caused by reaction raw material heated coke formation, of the electric heating bar sleeve in real time. The weighing device is connected with a data collecting module which is connected with a data processing module. The data processing module processes signals of a scale, and the percentage content of the coke amount is obtained.

Description

technical field [0001] The invention relates to the technical field of a measurement device and method, in particular to a device and method for measuring the coking tendency of solid-containing heavy raw materials when heated. Background technique [0002] Carbon deposition and coking of heavy raw materials in petrochemical processing is a common problem, such as delayed coking heating furnace tube coking, catalytic cracking unit riser, settler and oil transfer line coking, ethylene cracking unit cracking furnace tube coking, etc. . However, in the furnace tube of the coal direct liquefaction heating furnace, the heavy raw material is heated and coke is deposited on the inner wall of the furnace tube, and in severe cases, the furnace tube is blocked. The hidden dangers, resulting in unplanned shutdowns bring huge economic losses. Therefore, it is a very urgent technical requirement to suppress or reduce the coke deposition on the surface of equipment, pipelines and cataly...
