DCS control system used for amination workshop section in methyl cyclopentenolone production line

Abstract

The invention discloses a DCS control system used for an amination workshop section in a methyl cyclopentenolone production line. According to the invention, connecting pipelines of a hydrochloric acid storage tank, a methanol storage tank, a dimethylfuran storage tank and a liquid alkali storage tank with an amination kettle and an alkalization kettle are respectively provided with a flow meter; a PH meter, a component analyzer and a temperature sensor are correspondingly arranged on the amination kettle and the alkalization kettle; and the DCS control system controls devices like all cut-off valves and regulating valves according to feedback datum of the sensor on the amination workshop section, strictly and accurately controls process steps and drop-by-drop addition amount of reaction raw materials in the amination workshop section, realizes real-time control of steam and recycled water, and guarantees reaction temperature, so stable reaction process and more complete reaction are realized; human factors are eliminated; and the rate of finished products is improved.

Description

technical field [0001] The invention relates to the field of food additive production, in particular to a DCS control system for the amination section of a methylcyclopentenolone production line. Background technique [0002] Methylcyclopentenolone, also known as MCP, is a commonly used food additive, and the amination section is the most important in the production process of methylcyclopentenolone. The amination section includes salt formation, The three parts of amine methylation and alkalization are currently usually operated manually in a kettle. The dripping of raw materials is not accurate and the operation method is unstable, which is easily affected by human factors; The amount of material input becomes larger, and the material contact is not sufficient, so it is easy to cause incomplete reaction, so the yield of the product is low. Contents of the invention [0003] The object of the present invention is to provide a DCS control system for the amination section ...
