Recently, two sets of aromatization Shandong plant put into production,

gas processing project Adds "newcomer." With the value of gas

hydrocarbons are gradually excavated, in addition to aromatization

completely apart, isomerization, methyl ethyl ketone, butyl acetate and

other gas processing has been rapid development of gas catalytic cracking

process to be accelerated to as the main civil gas resources, consumption

structure, are turning to high value-added chemical products processing,

chemical products and liquefied petroleum gas processing, solvent

processing from the original, turned to the olefin and other basic raw

materials. Gas into chemical products deep processing times.
LPG is the main component of a mixture of propane and butane, and

accompanied by a small amount of propylene and butene. In recent years,

large-scale refineries come on stream, along with a substantial increase

in gas production, and gradually show signs of excess production; while

natural gas and other natural gas projects as well as dimethyl ether and

other alternative energy applications, further squeezing the liquefied

gas the civilian market, gas processing profits shrunk dramatically.

Processing into chemical products, liquefied petroleum gas has become an

important way.
Pushing gas level of profitability
Aromatization is the use of gas inside the olefin component, the

production of high octane aromatics and high-clean gas production

process, and liquefied petroleum gas and gasoline, aromatics and other

products spread significantly, thus the use of gas as a raw material for

profitable processing . Therefore, LPG and gasoline into aromatics, can

effectively improve the economic efficiency of local refineries. Since

2009, the local concentration of refineries in Shandong have been started

on the aromatization device. And now the new gas on the catalytic

cracking unit, is liquefied in the olefin components through pyrolysis,

propylene, industrial-grade isobutane, propane and mixed aromatic

hydrocarbons (blending component) as the main part of the gas cracker

there ethylene output.
According to a company of Dongying gas cracker person in charge of the

preparations, their yield of propylene is expected to reach 20% to 30%

ethylene yield is expected in 30% to 40%, the rest of propane, isobutane,

and mixed aromatic components , which isobutane purity above 95%.

Pyrolysis products of propylene, ethylene is higher than the price of

aromatics. According to Zhuo record information data show that olefin-

rich gas resources in Shandong Province mainstream market price - 6,200

yuan in 6 100 (t value, the same below), propylene market in the 12400 -

the mainstream price 12,500 yuan, the mainstream market price of propane

in 6000 ~ 6200 yuan, mixed aromatics mainstream price ~ 8300 yuan in

8200, 95% isobutane content of the mainstream market price in 5800 ~ 5900

yuan. A 20 million ton / year gas cracker gross margin is 1.23 times the

cost of production, creating an annual net profit is expected to reach

2.5 billion, catalytic cracker gas level of profitability is much higher

than aromatization device.
Upgrading of traditional craft products
Gas processing chemical products, but also some of the traditional

chemical production processes have an impact.
Butyl acetate traditional production process, is the use of acetic acid

and butanol dehydration from the reaction, the main raw material is

butanol, the current market price has risen to 15,000 yuan, of which

acetic acid in the current market price of 3,500 yuan, the final butyl

acetate generated the current market price is only 7500 yuan. Count

catalyst unit operating costs and labor costs, butyl acetate has been

well below the market price of the cost line, eliminate backward

production technology workers to find new methods of production is

imminent.
Relatively low gas prices butanol, the use of gas inside the olefin

component, butyl acetate can reduce the production cost of raw materials,

carbon-ene-product - high-octane gas, the octane number and the heat was

significantly increase, the market price around $ 5100, but also as a

vehicle for further processing liquefied petroleum gas, greatly reducing

overall costs, so that butyl acetate production cost of raw materials

needed in 3000 to 4,500 yuan, with a larger profit margins. Compared to

the acetic acid and butanol dehydration reaction of the process line, the

cost has been substantially reduced.
According to the reporter, Shandong Weifang Chemical Technology Co., Ltd.

Yixing produce 50,000 tons of butyl acetate, the project put into

operation, still have to start construction this year 50,000 tons / year

plant. Kenli Petrochemical, Shandong, Hebei joint petrochemical, Jilin

Petrochemical, Yangzi Petrochemical and Daqing Petrochemical Company have

launched plans for the project sec-butyl acetate.
Nourish the development of downstream products
China's fine chemical products, raw materials, production costs are high,

gas processing chemicals to liquefied petroleum gas as raw material

components for olefin aromatization, isomerization, catalytic cracking,

producing methyl ethyl ketone, butyl acetate, maleic anhydride with

hydrocarbons as raw material , butadiene, isobutylene, to produce

olefins, aromatics, alkanes and other 10 types of chemical products, this

will rise to Oxo alcohols, vinyl acetate, xylene, and more fine chemical

products. Gas catalytic cracking olefins with methanol to olefins is

expected to become common olefin resources to add. Shandong enterprises

intend to use a catalytic cracking gas and coal to take the propylene

synthesis gas (carbon monoxide and hydrogen) Oxo Oxo, gas processing

chemical products to the oil industry, coal chemical, salt chemical

industry chain to form a network.
It should be noted that chemical products, liquefied petroleum gas

processing project quickly launched, boosting the gas prices rise, the

current focus on gas processing project in Shandong, significantly higher

gas market conditions, raw material procurement is gradually transferred

to the outside.
