"The purity of the isobutane sample produced for the first time is about 95% .
On February 1 , the isobutane product produced by the n-butane plant has been passed three consecutive samples, and Fujian United Petrochemical successfully produced qualified isobutane for the first time.
In order to cooperate with the start-up of the new 300,000- tonne alkylation unit, the n-butane unit needs to produce about 560 tons of isobutane through the existing process flow , which is used as the bedding material for the start-up unit of the alkylation unit.
In the face of challenges, the first team of Fujian United Petrochemical Refining Co.
With the completion of the early-stage pipeline transformation and device purging work, the n-butane plant has entered the state of operation in an all-round way.
What caused it? How to adjust? Production managers, technical engineers and post personnel constantly check and observe operating conditions, carefully study the composition of raw materials and products, calculate heat balance and material balance, and analyze every possible cause.
The next focus is to find the optimal operating conditions to increase the concentration of isobutane.
