Small air separation plant 2000 solution in petroleum industry

Small air separation plant 2000 solution in petroleum industry
Project Background

The industrial gases used in petrochemical industry include oxygen and nitrogen. The main applications include the use of natural gas or heavy oil to produce synthetic ammonia, olefin and petrochemical products, and providing nitrogen for oil extraction. Based on the principle of mutual benefit and win-win cooperation, DEAR air separation plant and the client jointly signed the small air separation plant 2000 project again, the implementation of the project will be beneficial to the improvement of the customer's crude oil processing scale and the full play of the production equipment efficiency of the whole factory. Meanwhile, it expands the development space of oil products processing and improves the comprehensive economic benefits of products and the level of clean and green production. To promote the quality upgrade of oil products.

Scheme Introduction

Solution advantages

This unit adopts molecular sieve purification, pressurized turbine expansion machine to supply the unit with cooling capacity, and at the same time adopts double-tower and double-condensation nitrogen production process, and the extraction rate of nitrogen production reaches about 70%:

1. Good security

The whole set of equipment has low operating pressure, simple process, high level of equipment safety, long switching cycle of molecular sieve system, longer service life of switching valve and reducing potential safety hazard.

2. High reliability

Use water chilling unit to reduce the malfunction of dynamic equipment.

3. Convenient operation and maintenance, simple craft
