Plate Heat Exchanger for Pharmaceutical


Each of us should focus on a healthy diet. Take medicine when you are sick, and the safety and hygiene in drug production are key. Hofmann Company provides you with important heat transfer and heat exchange solutions for pharmaceutical products to ensure the hygienic production of pharmaceuticals.

1. Introduction to Pharmaceutical Technology

General pharmaceutical technology mainly includes the following stages:

Raw material, pretreatment, chemical reaction, separation, purification, product, preparation, and medicine.

Taking the synthesis of nitrobenzene as a pharmaceutical intermediate as an example, the process is introduced as follows:

2. Preparation of Nitrobenzene by Mixed Acid Nitration of Benzene

Mixed acid composition: HNO3 5%, H2SO4 68%, H2O 27%; the molar ratio of HNO3 in benzene to mixed acid is 1:1.1, and the reaction pressure is 0.46MPa; reaction temperature: 130 C; after the reaction, the nitrate enters the continuous separator, and after separation, the temperature of the acid nitrobenzene and the waste acid is about 120 C. The acidic nitrobenzene is sent to the refining section after cooling, alkali, water, and like.

3. Process Introduction

Power wave purification system is mainly used for dust removal and removal of arsenic, selenium, fluoride and other impurities. The dust furnace first enters the primary power wave washing device, rapidly cools and removes impurities, passes through the gas cooling tower for further cooling, and finally passes the second power wave washing device to further impurities and acid mist. The plate heat exchanger is mainly used to cool the cooling medium in the gas cooling tower to achieve circulating coolant. Hofmann can provide you with a full range of heat exchange solutions, greatly reducing your production costs. In addition, it can also provide you with heat exchanger spare parts and a subsequent heat exchanger cleaning and maintenance.
