The pipe size and heat exchanger volume are smaller than the low pressure process, so the cold box size is relatively small, the system running cold can be reduced; and because the expansion of the expander is smaller than the expansion ratio of the relatively low pressure process, the efficiency is higher. The instrument control system adopts S7-300 system of SIEMENS company in Germany. The main operating parameters are all introduced into the central control room. The display, recording and adjustment of process parameters and the sound and light alarm and emergency stop function of each equipment and unit are realized on the PLC. The differential pressure transmitter adopts the ST-900 series transmitter of Yokogawa Corporation of Japan, and the instrument control system is advanced and reliable as a whole. The nitrogen compressor was changed from the original two to a combined compressor, reducing investment and floor space. The compressor is imported from COOPER, USA, model TA50M6R3D/30, which is a six-stage compression centrifugal compressor with low maintenance, non-contact and semi-separated labyrinth seals and oil seals to ensure nitrogen compression. Absolutely no oil in the internal compression process to ensure product quality; at the same time, the QUAD2000 electronic control system of the compressor has constant pressure control, motor overload protection, setting and display of operating parameters and self-diagnosis function of the control system. Gas compressor. Huge liquid storage capacity, built two 500m3 liquid oxygen, liquid nitrogen storage tanks, can store nearly 20 days of production, which is very important to resist market risks and ensure the company's economic interests; The design of the tank is also special. The two oval 500 tanks are connected together in a single unit, and the floor space is reduced to a minimum. On the original limited site, sufficient safety distance for fire approval is provided.
