Petroleum refining, PRO-Environment, Chemical Technical Application, Technical Research, and Project Development are the activities carried out by Wanrong Environmental Protection Technology Co., Ltd. Project design: Manufacturing and selling of equipment. The company collaborates closely with Nanjing Chemical Research Institute and Sinopec Shanghai Research Institute. In the sector, technology has always been at the forefront. The company's most recent research and development of waste engine oil regeneration technology, which is geared toward the oil-gas phase of catalytic cracking, has been finished from the design, research and development volume production qualifying diesel goods.All gasoline and diesel products produced via tire oil-gas phase catalytic separation satisfy national standards for oil products. The Carclazyte New type Thin film + fractional distillation + NMP refining and regenerating base oil technology, along with the New type Thin film + fractional distillation + NMP refining and regenerating base oil technology, have attained international API requirements for their products.The organization is dedicated to the Technology First, Quality First philosophy. For every set of technology and equipment, simulation tests, equipment calculations, and process calculations are performed. Aspen, PRO2, HTRI, HExtran, SW-6, CAD, and Plant 3D were among the design programs used.
