How to reduce the initial investment and operation cost of low-temperature chiller for chemical plants

 Nowadays, chemical plants always consider how to reduce the initial investment and operation cost when they need to install a  low-temperature chiller system for the factory. Because low temperature refrigeration unit is a very important equipment in chemical plant, which plays an important role in safety production. The initial investment of low-temperature refrigeration unit is large, and it is also one of the equipment with large energy consumption in chemical plant. How to reduce the investment and operation cost of Glycol low temperature chiller and system is very important for enterprises.

This is one of H.Stars Group projects for one of the chemical base . The cryogenic unit and chilled water circulation system are designed and implemented .At first, the company's design engineers only chose the Ultra low temperature chiller and system design according to the cooling capacity required by customers. However, with the deepening of the project, H.Stars Group has found that the project can reduce the amount of chiller assembly by recycling the cooling capacity, so as to reduce the initial investment and operating costs.

This is a low-temperature crystallization chemical project. The whole process is heating up first and then cooling down to obtain different chemical products. The next stage of process cooling is completed by low-temperature refrigeration unit, and then the crystalline finished solution is separated by centrifuge. The separated low-temperature solution is cooled again in the previous process (called tank B) to obtain another product. However, because the volume of tank B is limited, it is necessary to supplement low-temperature water to obtain the desired product in tank B.

In this process, H.Stars Group has designed an external heat exchanger to be added to fully exchange the heat between the high-temperature mixture entering the tank B and the low-temperature solution, fully absorb the cold capacity of the low-temperature solution, and then enter the tank B to crystallize to form the product, thus greatly reducing the cost of low-temperature preparation cooling capacity of chiller unit.

Through such a change, the low-temperature chiller unit needed 1800kW before, but now it only needs 1300kW, and the investment cost and operation cost have been reduced by about 25%, which has brought great value to the enterprise. At the same time, H.Stars Group also realize that it is particularly important to fully understand the production process of customers for the selection of refrigeration equipment, which not only reduces the initial investment cost, but also greatly reduces the operation cost, bringing great value to customers.

H.Stars Group has rich experience in the design and selection of low temperature chiller unit, and 28 years of professional experience has won constant praise in the field of cryogenic chemical industry.
