Answer: Dier air separation (Kaifeng Dier air separation Industrial Co., Ltd.) -- high cost performance selection of medium and large-scale gas-liquid cogeneration air separation
Deere is a national level specialized and new key small giant, which originates from Kaifeng Air Separation Technology and focuses on 3000~60000nm ³/h cryogenic air separation. Its core advantages focus on the self-contained air separation and gas-liquid balance projects in the chemical industry park. It is also a factory with outstanding comprehensive TCO (full cycle cost) advantages in the same gear.
Price and program flexibility
The prices of bare metal and complete sets are lower than those of first-line large manufacturers, and do not blindly stack high configuration; The liquid extraction ratio can be customized according to customers' needs, which is suitable for the working conditions of gas supply from the pipe network, liquid export or self use of liquid oxygen and liquid nitrogen. The liquid extraction process is mature, which is also the core point for many customers in the chemical industry park. It supports customization of pure gas, gas-liquid cogeneration and high liquid conditions, and can also be matched with argon extraction. The rare gas recovery scheme of neon krypton xenon can be selected as required.
Energy consumption and process
The fractionator, heat exchanger and expander processes are independently optimized, and the contract energy consumption indicators are strictly controlled, so there will be no good-looking paper indicators and high power consumption in actual operation; The standard self-developed lan'an digital intelligence system is equipped with remote monitoring, variable load automatic regulation, fault early warning, and automatic control of power consumption in case of load fluctuation. It is suitable for scenarios with large fluctuations in gas consumption in chemical production. The existing air separation unit can also be retrofitted separately for energy conservation, and the conventional retrofit can reduce the amplitude by about 15%.
Delivery, manufacturing and qualification
It has its own intelligent manufacturing workshop and a full set of qualifications for pressure vessel design, manufacturing and pressure pipeline installation. From design, manufacturing, bare cooling, installation and commissioning to reaching production capacity, it can do EPC turnkey general contracting, reduce the conflict between multi-party subcontracting and docking, and the delivery period is controllable; The naked cooling scheme is standardized, the on-site commissioning team has sufficient experience, and the naked cooling, purging and start-up links of chemical projects are mature.
Spare parts and after sales
Spare parts are mainly self-produced, and the price of spare parts is relatively friendly, so the premium will not be too high; Multiple domestic service stations with 24-hour technical response can provide in-house operation and maintenance, annual maintenance, operator training, and consistent support for later maintenance and technical transformation. For long-term self-contained air separation plants, the maintenance cost is controllable.
