Abstract

The invention provides a detecting device for wax content in a synthetic gas, comprising a first cooling part, a flow detecting element and a weighing part, wherein the synthetic gas is introduced into the first cooling part to be subjected to cooling separation of wax and gas, the flow detecting element is arranged at the outlet end of the first cooing part and used for detecting the volume of gas discharged from the first cooling part, and the weighing part weighs the initial mass and the cooling mass of the first cooling part. When the detecting device disclosed by the invention is used, the wax and the gas are separated in the first cooling part, the wax is condensed to be solid, the mass of the solid wax can be weighed by the weighing part after the experiment is completed, the volume of the gas can be measured by the flow detecting element, and then the percentage of the mass of the solid wax in the volume of the gas can be obtained by calculation, so that the content of the wax in the synthetic gas can be measured, and workers can timely regulate production, thus overhigh content of the wax in the synthetic gas can be avoided, the production quality is ensured, the production cost is lowered, and the problem that the wax blocks the equipment is solved.

Description

technical field [0001] The invention relates to the technical field of wax content detection in gas, and more specifically, to a detection device for wax content in synthesis gas. Background technique [0002] In the present invention, synthesis gas refers to coal-to-methanol synthesis outlet gas. [0003] Coal-to-methanol is synthesized from hydrogen, carbon monoxide and a small amount of carbon dioxide, using Cu-Al-Zn as a catalyst to synthesize methanol. During this reaction process, a small amount of acid substances corrode the equipment pipeline to generate iron ions, which form complexes with carbon monoxide in the synthesis gas, thereby accelerating the formation of waxes, ethers, higher alcohols and other substances. Among them, wax is a hydrocarbon mixture containing more than 15 carbons. It is liquid when it is higher than 40 degrees Celsius, and it adheres to the tube wall of heat exchanger, separator and equipment in a solid (viscous) state when it is lower than...
