Abstract

The invention relates to the technical field of carbon removal, particularly provides a carbon remover for heat-conducting oil and a removing method, and aims to solve the problem that carbon deposits of a heat-conducting oil system are difficultly cleaned. The carbon remover comprises, by weight, 20-30 parts of basic water, 27-37 parts of anionic surface active agents, 22-32 parts of non-ionic surface active agents and 10-20 parts of complex agents. The removing method of the heat-conducting oil includes the steps: treating the heat-conducting oil by the aid of the carbon remover; adding the complex agents and process water into the heat-conducting oil to uniformly mix and stir; circularly heating to remove carbon deposits in the heat-conducting oil. Removing efficiency of the carbon deposits reaches 98% or more, influence of the carbon deposits to heat-conducting oil performances is reduced, the service life of the heat-conducting oil is prolonged, operating cost is reduced, and heat utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of carbon removal, and in particular provides a carbon removal agent for heat transfer oil and a removal method. Background technique [0002] Heat transfer oil is an excellent medium for conducting heat. It can be used as both a heating medium and a cooling medium. It has the advantages of uniform heat transfer, high temperature under lower pressure, simple operation and convenient transportation. It is an indispensable heat transfer medium in the rapid development of modern continuous automation fine chemical industrial production. With the continuous operation of the heat transfer oil system, the heat transfer oil undergoes oxidative polymerization or condensation reaction with oxygen at high temperature, so that the viscosity of the heat transfer oil in the system increases, and the heat transfer oil in the heat transfer oil system is formed due to the reduced flow rate of the heat transfer oil. , the c...
