General：
Heat exchanger is commonly applied to coal chemical industry, petrochemical, fine chemical industry and others, such as ammonia, coal liquifaction, coal gas, coal tar and other projects for energy recovery and recycling.

Doright Heat exchangers are divided into high temperature heat exchangers and cryogenic heat exchangers.
UHT heat exchangers: Temperature range is 650℃ to 1020℃. Heat resulting from chemical processing could be transferred to the medium through row tubes for recycle. This kind of equipment is widely used in the energy recovery of smoke gas coming from carbon black smoke, waste incineration and coal gas.
Waste gas energy recovery project of SMDERI in Nantong
Heat recovery projects for carbon black process in carbon black industries
Sludge incineration project of Degremont (Beijing) in Shenzhen
Cryogenic heat exchangers are widely applied to projects of synthesis of ammonia, coal liquifaction, coal gas, and coal tar, etc.
Supplying full sets of heat exchangers to Xinjiang Qinghua for coal tar lightening 500,000t/a, including equipment made of chrome-molybdenum steel and composite board material.
Supplying methanol synthesis exhaust heat exchanger that is made of 09MnNiDR with pressure level of 3.9MPa.
